Book excerpt: Petrophysical and geomechanical properties of the formation such as Young's modulus, bulk modulus, shear modulus, Poisson's ratio, and porosity provide characteristic description of the hydrocarbon reservoir. It is well-established that static geomechanical properties are good representatives of reservoir formations; however, they are non-continuous along the wellbore, expensive and determining these properties may lead to formation damage. Dynamic geomechanical formation properties from acoustic measurements offer a continuous and non-destructive means to provide a characteristic description of the reservoir formation. In the absence of reliable acoustic measurements of the formation, such as sonic logs, the estimation of the dynamic geomechanical properties becomes challenging. Several techniques like empirical, analytical and intelligent systems have been used to approximate the property estimates. These techniques can also be used to approximate acoustic measurements thus enable dynamic estimation of geomechanical properties. This study intends to explore methodologies and models to dynamically estimate geomechanical properties in the absence of some or all acoustic measurements of the formation. The present work focused on developing empirical and intelligent systems like artificial neural networks (ANN), Gaussian processes (GP), and recurrent neural networks (RNN) to determine the dynamic geomechanical properties. The developed models serve as a cost-effective, reliable, efficient, and robust methods, offering dyanmic geomechanical analysis of the formation. This thesis has five main contributions: (a) a new data-driven empirical model of estimating static Young's modulus from dynamic Young's modulus, (b) a new data-driven ANN model for sonic well log prediction, (c) a new data-driven GP model for shear wave transit time prediction, (d) a new dynamic data-driven RNN model for sonic well log reproduction, and (e) an assessment on the ANN as a reliable sonic logging tool.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable assessment of static and dynamic petrophysical properties of hydrocarbon-bearing reservoirs is critical for estimating hydrocarbon reserves, identifying good production zones, and planning hydro-fracturing jobs. Conventional well-log interpretation methods are adequate to estimate static petrophysical properties (i.e., porosity and water saturation) in formations consisting of thick beds. However, they are not as reliable when estimating dynamic petrophysical properties such as absolute permeability, movable hydrocarbon saturation, and saturation-dependent capillary pressure and relative permeability. Additionally, conventional well-log interpretation methods do not take into account shoulder-bed effects, radial distribution of fluid saturations due to mud-filtrate invasion, and differences in the volume of investigation of the various measurements involved in the calculations. This dissertation introduces new quantitative methods for petrophysical and compositional evaluation of water- and hydrocarbon-bearing formations based on the combined numerical simulation and nonlinear joint inversion of conventional well logs. Specific interpretation problems considered are those associated with (a) complex mineral compositions, (b) mud-filtrate invasion, and (c) shoulder-bed effects. Conventional well logs considered in the study include density, photoelectric factor (PEF), neutron porosity, gamma-ray (GR), and electrical resistivity. Depending on the application, estimations yield static petrophysical properties, dynamic petrophysical properties, and volumetric/weight concentrations of mineral constituents. Assessment of total organic carbon (TOC) is also possible in the case of hydrocarbon-bearing shale. Interpretation methods introduced in this dissertation start with the detection of bed boundaries and population of multi-layer petrophysical properties with conventional petrophysical interpretation results or core/X-Ray Diffraction (XRD) data. Differences between well logs and their numerical simulations are minimized to estimate final layer-by-layer formation properties. In doing so, the interpretation explicitly takes into account (a) differences in the volume of investigation of the various well logs involved, (b) the process of mud-filtrate invasion, and (c) the assumed rock-physics model. Synthetic examples verify the accuracy and reliability of the introduced interpretation methods and quantify the uncertainty of estimated properties due to noisy data and incorrect bed boundaries. Several field examples describe the successful application of the methods on (a) the assessment of residual hydrocarbon saturation in a tight-gas sand formation invaded with water-base mud (WBM) and a hydrocarbon-bearing siliciclastic formation invaded with oil-base mud (OBM), (b) estimation of dynamic petrophysical properties of water-bearing sands invaded with OBM, (c) estimation of porosity and volumetric concentrations of mineral and fluid constituents in carbonate formations, and (d) estimation of TOC, total porosity, total water saturation, and volumetric concentrations of mineral constituents in the Haynesville shale-gas formation. Comparison of results against those obtained with conventional petrophysical interpretation methods, commercial multi-mineral solvers, and core/XRD data confirm the advantages and flexibility of the new interpretation techniques introduced in this dissertation for the quantification of petrophysical and compositional properties in a variety of rock formations.

Book excerpt: Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.

This book was released on 2019 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the Haynesville shale has become a target for natural gas exploitation, especially with the advent of horizontal drilling and hydraulicfracturing. Located in East Texas and Northwest Louisiana, it is believed to be one of the largest producing natural gas plays in the U.S., with estimated recoverable reserves of around 75 TCF according to the Energy Information Administration (EIA, 2011). Current total daily production for the entire play is around 5.4 Bcf/d. The economic potential of the Haynesville shale gas play is propelled by recent gradual rebounds in natural gas prices, increased industrial utilization of gas, and expansion of LNG export terminals along the gulf coast due to the lifting of the decades-old ban on exporting petroleum products. Consequently, it is imperative to properly evaluate the petrophysical attributes of the shale in order to understand the reservoir characteristics that may ultimately influence production. This study focused on the petrophysical evaluation of wells in East Texas and Northwest Louisiana. Wireline logs and core data were integrated to provide a predictive template for targeting and landing lateral wellbores within the shale in order to provide useful insight for hydraulic fracture stimulation with the view of optimizing production. The critical factors determined to influence the target zones include geomechanical properties such as brittleness, and geochemical properties such as the mineral volumes in the rock. These were calculated from logs using equations previously published in literature and correlated to nearby core measurements for verification. Already drilled and completed laterals were also evaluated to identify potential refracturing opportunities that could remedy production decline. The stimulation techniques and production outcomes of these laterals were examined in an attempt to identify possible trends and contrasts accordingly. The results show that the geomechanical properties vary across the shale play area. The geomechanical and geochemical properties can be useful in target selection for landing horizontal wells and effective fracture treatments, but they cannot by themselves guarantee productivity as other factors have to be taken into consideration such as completions method. The various operational constraints and development patterns such as different lateral lengths and age/style of completions make it difficult to do effective well-to-well production comparison; however the results points to trends such as longer lateral lengths with greater fracture stages to boost production. Additionally, in some areas, it has been established via the petrophysical analysis that there may be additional intervals in which to land a second horizontal well. This will surely lead to better exploitation and increased production from the reservoir.
