Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic fracturing is a common method employed to increase the production of oil and gas fields. Recently, there has been increased interest in monitoring the microearthquakes induced by hydraulic fracturing as a means of obtaining data to characterize reservoir changeS induced by the injection. Two types of microearthquakes have been observed during hydraulic fracturing. Tensile events have been observed and modeled as the parting of the surfaces of a fracture. A majority of the events observed have been shear-slip events, where two sides of a fault plane slip parallel to each other but in opposite directions. The locations of the microearthquakes can be analyzed to determine regions where significant seismic energy was released, which presumably are regions where injected fluid penetrated into the rock along pre-existing fractures or zones of weakness. The spatial patterns in the locations can be analyzed to fine regions where events cluster along planes, which are interpreted to be the dominant fluid flow paths. Imaging methods can also be applied to the travel time and waveform data to obtain direct evidence for the locations of the fractures or fracture zones. 27 refs., 2 figs.

This book was released on 2013-08-14 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past several years, some energy technologies that inject or extract fluid from the Earth, such as oil and gas development and geothermal energy development, have been found or suspected to cause seismic events, drawing heightened public attention. Although only a very small fraction of injection and extraction activities among the hundreds of thousands of energy development sites in the United States have induced seismicity at levels noticeable to the public, understanding the potential for inducing felt seismic events and for limiting their occurrence and impacts is desirable for state and federal agencies, industry, and the public at large. To better understand, limit, and respond to induced seismic events, work is needed to build robust prediction models, to assess potential hazards, and to help relevant agencies coordinate to address them. Induced Seismicity Potential in Energy Technologies identifies gaps in knowledge and research needed to advance the understanding of induced seismicity; identify gaps in induced seismic hazard assessment methodologies and the research to close those gaps; and assess options for steps toward best practices with regard to energy development and induced seismicity potential.

Available in PDF, EPUB and Kindle. Book excerpt: Microearthquakes induced by hydraulic fracturing have been studied by many investigators to characterize fracture systems created by the fracturing process and to better understand the locations of energy resources in the earth's subsurface. The pattern of the locations often contains a great deal of information about the fracture system stimulated during the hydraulic fracturing. Seismic tomography has found applications in many areas for characterizing the subsurface of the earth. It is well known that fractures in rock influence both the P and S velocities of the rock. The influence of the fractures is a function of the geometry of the fractures, the apertures and number of fractures, and the presence of fluids in the fractures. In addition, the temporal evolution of the created fracture system can be inferred from the temporal changes in seismic velocity and the pattern of microearthquake locations. Seismic tomography has been used to infer the spatial location of a fracture system in a reservoir that was created by hydraulic fracturing.

Available in PDF, EPUB and Kindle. Book excerpt: The main goal of the thesis is to characterize the attributes of conventional and unconventional reservoirs through passive seismicity. The dissertation is comprised of the development and applications of three new methods, each of which focuses on a different aspect of fractures/faults and the resulting seismicity. In general, the thesis work discusses reservoir characterization from two aspects: 1) understanding fractures and faults in reservoirs as seismic sources with induced seismicity, and then inferring other properties of the reservoirs, such as stress regime and velocity structure (Chapters 2, 3, 4); 2) understanding the fractures in reservoirs as seismic scatterers (Chapter 5). First, I introduce a new method to determine the source mechanisms of the induced earthquakes by incorporating high frequency waveform matching, first P-arrival polarities and average S/P amplitude ratios. The method is applied to 40 induced earthquakes from an oil/gas field in Oman monitored by a sparse near-surface seismic network and a deep borehole seismic network. The majority of the events have a strike direction parallel with the major NE-SW faults in the region, and some events trend parallel with the NW-SE conjugate faults. The results are consistent with the in-situ well breakout measurements and the current knowledge of the stress direction of this region. The source mechanisms of the studied events together with the hypocenter distribution indicate that the microearthquakes are caused by the reactivation of preexisting faults. Then I introduce a new method to locate microseismic events induced by hydraulic fracturing with simultaneous anisotropic velocity inversion using differential arrival times and differential back azimuths. We derive analytical sensitivities for the elastic moduli (Cij) and layer thickness L for the anisotropic velocity inversion. The method is then applied to a microseismic dataset monitoring a Middle Bakken completion in the Beaver Lodge area of North Dakota. Our results show: 1) moderate-to-strong anisotropy exists in all studied sedimentary layers, especially in both the Upper Bakken and Lower Bakken shale formations, where the Thomsen parameters (E and y) can be over 40%; 2) all events selected for high signal-to-noise ratio and used for the joint velocity inversion are located in the Bakken and overlying Lodgepole formations, i.e., no strong events are located in the Three Forks formation below the Bakken; 3) more than half of the strong events are in two clusters at about 100 and 150 meters above the Middle Bakken. Re-occurrence of strong, closely clustered events suggests activation of natural fractures or faults in the Lodgepole formation. Finally, I introduce a new hybrid method to model the shear (SH) wave scattering from arbitrarily shaped fractures embedded in a heterogeneous medium by coupling the boundary element method (BEM) and the finite difference method (FDM) in the frequency domain. The hybrid method can calculate scattering from arbitrarily shaped fractures very rapidly, thus Monte Carlo simulations for characterizing the statistics of fracture attributes can be performed efficiently. The advantages of the hybrid method are demonstrated by modeling waves scattered from tilted fractures embedded in complex media. Interesting behaviors of the scattered waves, such as frequency shift with the scattering order and coherent pattern of scattered waves through strong heterogeneities, are observed. This method can be used to analyze and interpret the scattered coda waves in the microseismic observations, e.g., the reverberating multiples in the Bakken microseismic data which cannot be explained by the determined layered anisotropic velocity model alone.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The classical concept of hydraulic fracturing is that large, wing-shaped tensile fractures propagate away from the wellbore. However, in low matrix permeability settings such as Enhanced Geothermal Systems (EGS) and gas shale, hydraulic fracturing creates complex networks that may contain both newly formed fractures and stimulated natural fractures. In this research, the overall approach has been to integrate field observations, laboratory observations, and understanding of fundamental physical processes into computational modeling that is specifically designed for complex hydraulic fracturing and to apply the modeling to develop deeper understanding and to solve practical problems. A computational model was developed that coupled fluid flow, stresses induced by fracture opening and sliding, transmissivity coupling to deformation, friction evolution, and fracture propagation in two-dimensional discrete fracture networks. The model is efficient enough to simulate networks with thousands of fractures. A variety of novel techniques were developed to enable the model to be accurate, efficient, realistic, and convergent to discretization refinement in time and space. Testing demonstrated that simulation results are affected profoundly by the stresses induced by fracture deformation, justifying the considerable effort required to include these stresses in the model. Four conceptual models were formulated that represent the main hypotheses about stimulation mechanism from the literature of hydraulic fracturing. We refer to the stimulation mechanisms as Pure Opening Mode (POM), Pure Shear Stimulation (PSS), Mixed-Mechanism Stimulation (MMS), and Primary Fracturing with Shear Stimulation Leakoff (PFSSL). Computational models were used to investigate the properties of each mechanism. Geological factors that affect stimulation mechanism were identified. Techniques for diagnosing stimulation mechanism were devised that incorporate interpretation of bottom hole pressure during injection, shut-in, and production, microseismic relocations, and wellbore image logs. A Tendency to Shear Stimulation (TSS) test was proposed as a way to help diagnose the mechanism by unambiguously measuring a formation's ability to experience shear stimulation. Modeling results suggested several potential sources for error in estimation of the least principal stress in low matrix permeability settings. The Crack-like Shear Stimulation (CSS) mechanism was identified as a potentially important physical process that may control the spreading of shear stimulation through the interaction of fluid flow, deformation, and slip-transmissivity coupling. The computational model also has the capability to couple fluid flow with rate and state earthquake simulation. The model was used to investigate the interaction of fluid flow, permeability evolution, and induced seismicity during injection into a single large fault. Using the model, a variety of observations about induced seismicity in EGS were explained. Producing fluid back after injection and gradually reducing injection pressure during stimulation were identified as strategies for minimizing induced seismicity. A review of historical EGS projects demonstrated that the severity of induced seismicity has been correlated to the degree of brittle fault zone development in the interval of injection. The fracture networks at each project were categorized along a continuum from thick, porous fault zones to thin cracks. Observations from specific EGS projects fell across the full continuum, a result that has implications not only for induced seismicity, but for fractured reservoirs in general. A pressure transient analysis was performed using data from the EGS project at Soultz-sous-Forêts. At Soultz, fluid injection induced slip and transmissivity enhancement in large fault zones. The pressure transient analysis showed that these fault zones are best described as slabs of single porosity, single permeability material. Evidence of dual porosity behavior was not found.

Book Synopsis Induced Microearthquakes and Seismicity-Permeability Relationships in Fractures by : Yi Fang
Download or read book Induced Microearthquakes and Seismicity-Permeability Relationships in Fractures written by Yi Fang and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Permeability evolves monotonically for smooth fractures but in a fluctuating pattern for highly roughened fractures. A higher roughness is likely to result in alternating compaction and dilation during shearing. Significant permeability damage may occur for rough samples when asperities are highly worn with wear products blocking fluid pathways. (4) There is no obvious correlation between permeability evolution and frictional behavior for rough fracture samples when fractures are subject to sudden sliding velocity change. Implications of our lab-scale experimental results suggest that characterization of fracture geometry would be beneficial for better understanding and managing induced seismicity and permeability development. In shale reservoir stimulation, fractures are propped to increase the permeability of the formation. On the other hand, the proppants may also influence the frictional strength of fractures. Thus, in the appendix, we explore the evolution of friction and permeability of a propped fracture using shearing-concurrent measurements of permeability during constant velocity shearing experiments. We observe that (1) the frictional response is mainly controlled by the normal stress and proppant thickness. High normal stress results in the crushing of proppant particles although this change in particle size distribution has almost no impact on the frictional response of the proppant-fracture system. The depth of shearing-concurrent striations on fracture surfaces suggests that the magnitude of proppant embedment is controlled by the applied normal stress. Moreover, under high normal stress, the reduced friction implies that shear slip is more likely to occur on propped fractures in deeper reservoirs. The increase in the number of proppant layers, from mono-layer to triple-layers, significantly increases the friction of the propped fracture due to the interlocking of the particles and jamming, suggesting that high proppant density during emplacement would help stabilize the fractures during injection. (2) Permeability of the propped fracture is mainly controlled by the magnitude of the normal stress, the proppant thickness, and the proppant size. Permeability of the propped fracture decreases during shearing due to proppant particle crushing and related clogging. Compared to the multi-layered specimen, the mono-layer case which has fewer displacement degrees-of-freedom exhibits the smallest initial permeability due to proppant embedment. Proppants are prone to crushing if the shear loading evolves concurrently with the normal loading. These combined conclusions suggest that the use of high-density proppants not only provides high hydraulic conductivity for hydrocarbon production but may also help to mitigate the risk of induced seismicity.

Available in PDF, EPUB and Kindle. Book excerpt: North America's largest hydraulic fracturing opeations have been conducted at Fenton hill, New mexico to creae hot dry rock geothermal reservoirs. Microearthquakes induced by these fracturing operations were measured with geophones. The large volume of rock over which the microearthquakes were distributed indicates a mechanism of hydraulic stimulation which is at odds with conventional fracturing theory, which predicts failure along a plane which is perpendicular to the least compressive earth stress. Shear slippage along pre-existing joints in the rock is more easily induced than conventional tensile failure, particularly when the difference between minimum and maximum earth stresses is large and the pre-existing joints are oriented at angles between 30 and 60)degree) to the principal earth stresses, and a low viscosity fluid like water is injected. Shear slippage results in local redistribution of stresses, which allows a branching, or dendritic, stimulation pattern to evolve, in agreement with the patterns of microearthquake locations. Field testing of HDR reservoirs at the Fenton Hill site shows that significant reservoir growth occurred as energy was extracted. Tracer, microseismic, and geochemical measurements provided the primary quantitative evidence for the increases in accessible reservoir volume and fractured rock surface area. These temporal increases indicate that augmentation of reservoir heat production capacity in hot dry rock system occurred. For future reservoir testing, Los Alamos is developing tracer techniques using reactive chemicals to track thermal fronts. Recent studies have focused on the kinetics of hydrolysis of derivatives of bromobenzene, which can be used in reservoirs as hot as 275)degree)C.

Book Synopsis Long Period Long Duration Seismic Events During Hydraulic Stimulation of Gas Reservoirs by : Indrajit Das

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis attempts to identify and characterize the range of deformation processes that occurs during hydraulic stimulation of extremely low-permeability shale-gas reservoirs. The aim is to improve the mechanical understanding on how multi-stage hydraulic fracturing leads to reservoir stimulation. While monitoring the microseismicity that accompanies hydraulic fracturing provides information about the depth, extent and growth patterns of the induced fracture network, several lines of evidence indicate that microearthquakes are only part of the total deformation. The central topic of this dissertation is to describe a previously unknown class of Long Period Long Duration (LPLD) seismic events, much larger in magnitude than microearthquakes. Interpreted to represent sustained slow slip on relatively large faults, LPLD events can help explain the development of hydraulically conductive surface area and the overall increase in reservoir permeability associated with hydraulic fracturing. More importantly, the LPLD events are indicative of potentially widespread slow aseismic processes that enhanced the effectiveness of the hydraulic fracturing process. The first chapter introduces the problem of understanding hydraulic fracturing in shale gas reservoirs in the light of recorded seismic signals during the monitoring process. It also talks about the motivation for this research. The second chapter discusses the advantages of applying passive seismic tomography to a typical microseismic data set recorded in a single, nearly vertical well to monitor hydraulic stimulation of a shale-gas reservoir. In this method, the event locations and the velocity model are estimated simultaneously unlike the conventional industry practice of using a fixed velocity model derived from sonic logs and perforation-shots. Essentially the velocity model and the event locations are constantly updated till the desired fit is achieved. In this way we are making use of the information carried by the microearthquakes themselves for improving the model and consequently, the locations. This added flexibility not only makes it possible to accurately predict traveltimes of the recorded P- and S-waves, but also provides a convincing evidence for anisotropy of the examined shale formation. While we find that velocity heterogeneity does not need to be introduced to explain the data acquired for each stage of hydraulic fracturing, the obtained models are suggestive of possible time-lapse changes in the anisotropy parameters that characterize the stimulated reservoir volume. The third and fourth chapters discuss the principal topic of the thesis, which is identifying, characterizing and locating LPLD seismic events that have been observed during hydraulic fracturing in several shale-gas and tight-gas reservoirs. The LPLD events are low amplitude signals lasting for 10-100 seconds and are most conspicuous in the 10-80 Hz frequency band and are identified by their high amplitudes in stacked spectrograms in this particular frequency band. Band-pass filtering of the raw seismic data in this band is used to eventually isolate all the LPLD events. Third chapter of this thesis describes the waveform characteristic of the LPLD events and the fourth chapter discusses the location and mechanism of these events. LPLD events are similar in appearance to tectonic tremor sequences observed in subduction zones and transform fault boundaries. LPLD events, which are complex but coherent wave trains, have finite moveouts, the direction and amount of which confirms that they originate in the reservoir. They are predominantly composed of S-waves but weaker P-waves have also been identified. In some cases, microearthquakes are observed to occur during the LPLD events. Based on the similarity with tectonic tremor and our observations of several impulsive S-wave arrivals within the LPLD events, LPLD events have been interpreted as resulting from the superposition of shear slip events on relatively large faults. Using a method akin to empirical Green's function, the energy carried by the larger LPLD events is estimated to be about ~1000 times greater than a microseismic event of moment magnitude (MW) ~ -2, that is typical of the events that occur during hydraulic stimulation. In the course of the entire stimulation activity, LPLD events were found to release cumulatively, as much as two orders of magnitude higher energy than the microearthquakes. The large size of these LPLD events compared to microearthquakes suggests that they represent slip on relatively large faults during stimulation of these extremely low-permeability reservoirs. The fourth chapter describes how within the limitations of the recording geometry, it is possible to determine the general area in the reservoir from which the events originate for the two case studies in the Barnett shale. In the first study, LPLD events occur in the region where the density of natural fractures as well as the fluid pressure during pumping was highest. In the second case study, the LPLD events are observed to occur between two wells and seem to establish a hydraulic connection between these wells. In both data sets, the LPLD events occur in areas with very few microearthquakes. There are likely many faults in the reservoir not producing microseismicity that are slowly slipping in response to the stimulation; LPLD events are, however, expected to be generated where faults large enough to produce a sequence of slow slip events exist. A combination of factors such as high fluid pressure and/or high clay content is potentially responsible for slow slip on faults. This thesis identifies a number of topics for future studies (hopefully better data sets having improved recording geometries and sensors) to better study the relation of LPLD events to microearthquakes. LPLD events can provide useful insights into the primary deformation mechanism responsible for production post hydraulic stimulation. Knowing that these newly discovered events evidently caused by pervasive slow slip on relatively large faults are significantly impacting the stimulation of these extremely low-permeability reservoirs, it might be possible to better design reservoir stimulation by mapping the distribution of faults and fractures and areas with rock properties that favor slow slip.
