Available in PDF, EPUB and Kindle. Book excerpt: Oil recovery by steam injection is a proven, successful technology for nonfractured reservoirs, but has received only limited study for fractured reservoirs. Preliminary studies suggest recovery efficiencies in fractured reservoirs may be increased by as much as 50% with the application of steam relative to that of low temperature processes. The key mechanisms enhancing oil production at high temperature are the differential thermal expansion between oil and the pore volume, and the generation of gases within matrix blocks. Other mechanisms may also contribute to increased production. These mechanisms are relatively independent of oil gravity, making steam injection into naturally fractured reservoirs equally attractive to light and heavy oil deposits. The objectives of this research program are to quantify the amount of oil expelled by these recovery mechanisms and to develop a numerical model for predicting oil recovery in naturally fractured reservoirs during steam injection. The experimental study consists of constructing and operating several apparatuses to isolate each of these mechanisms. The first measures thermal expansion and capillary imbibition rates at relatively low temperature, but for various lithologies and matrix block shapes. The second apparatus measures the same parameters, but at high temperatures and for only one shape. A third experimental apparatus measures the maximum gas saturations that could build up within a matrix block. A fourth apparatus measures thermal conductivity and diffusivity of porous media. The numerical study consists of developing transfer functions for oil expulsion from matrix blocks to fractures at high temperatures and incorporating them, along with the energy equation, into a dual porosity thermal reservoir simulator. This simulator can be utilized to make predictions for steam injection processes in naturally-fractured reservoirs. Analytical models for capillary imbibition have also been developed.

This book was released on 2011 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spontaneous imbibition is one of the key mechanisms for oil production from naturally fractured reservoirs. The final oil recovery and the rate of oil recovery by spontaneous imbibition depend on many rock and fluid properties and wettability of the rock. Important factors that affect wettability are the rock type, initial water saturation, crude oil type, aging time, brine composition and salinity, and displacement temperature. Understanding wettability through spontaneous imbibition studies is crucial because wettability can affect the fluid location, fluid flow, and residual oil distributions of reservoirs. Many factors that affect imbibition oil recovery and wettability have not been studied extensively for carbonates. Better understanding of the effects of wettability and scaling laboratory spontaneous imbibition data is important to predicting oil recovery from fractured reservoirs. The objectives of the present study were to investigate various crude oil/brine/rock (COBR) interactions and factors which could affect wettability, to evaluate correlation of spontaneous imbibition data with various wetting conditions for carbonates, and to improve oil recovery by spontaneous imbibition with change in invading brine composition and salinity and by use of surfactants. Reproducibility of the spontaneous imbibition results is also emphasized. The variation of aqueous phase viscosity was performed for three distinct wettability conditions classed as Very Strongly Water-Wet (VSWW), Uniformly-Wet (UW-CO) and Mixed-Wet (MXW), to study the effects on spontaneous imbibition as well as to extend previous studies on spontaneous imbibition correlations. The Mason et al. (2010) scaling group (a modification of the Ma et al. (1997) scaling group) developed mainly for wide variation in aqueous phase viscosities of VSWW Berea sandstone was used to satisfactorily correlate most of the data obtained for VSWW carbonate spontaneous imbibition results. The mechanism of VSWW imbibition was investigated by use of Magnetic Resonance Imaging (MRI) to monitor oil recovery from spontaneous imbibition of brine. The saturation profiles and images obtained for linear and radial imbibition indicate that the pore structure plays a significant role during spontaneous imbibition of brine into an oil saturated rock. Formation of a sharp piston-like imbibition front also validates previous assumptions made for development of imbibition scaling groups. Under wettability conditions that made capillary forces very weak, imbibition was controlled by change in density of the aqueous phase. For UW-CO, improved correlation was given by using weighted viscosity terms. Data was correlated by scaling with respect to the product of dimensionless time (basically the ratio of capillary to viscous forces) times the ratio of gravity to capillary forces. The initial water saturation, crude oil type, aging time, and displacement temperature have been varied for selected rocks to evaluate wettability and its effects on oil recovery by spontaneous imbibition. Improved oil recovery was demonstrated for spontaneous imbibition through reduction in invading brine salinity and also by addition of various types of anionic, amphoteric, cationic, and nonionic surfactants. Increases in recovery were fastest and highest for nonionic surfactants.

Mayorquin-Ruiz and published by . This book was released on 2015 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alternatives for enhanced oil recovery processes in heavy oil containing deep naturally fractured reservoirs (NFR) are limited due to excessive heat losses when steam is injected. Air injection at high temperature oxidation conditions (in-situ combustion) has been considered as an alternative to aqueous based thermal applications. However, its implementation has serious limitations including poor areal distribution of injected air and poor combustion efficiency due to the heterogeneous nature of these reservoirs as well as the safety risk of unconsumed injected oxygen (O2) reaching the production wells. Taking advantage of the low cost and availability of air, one option is to use air at low temperature conditions (low temperature oxidation, LTO) as a pressurizing agent in NFR. Oxygenated compounds are generated at these conditions resulting in oil viscosity increase, reducing fluid mobility. In order to minimize this detrimental effect, a combination of air injection with hydrocarbon solvents can be applied. The objectives of this thesis are to evaluate air injection at LTO conditions in NFR containing heavy oil as a way to improve oil recovery, to clarify the effect of hydrocarbon solvent addition into air on oil recovery and O2 consumption, and to propose optimal conditions (temperature, air/solvent ratio) and implementation strategies for an efficient use of this suggested method. Comprehensive laboratory and numerical simulation studies were conducted to achieve these objectives. Static diffusion experiments--simulating cyclic gas injection (huff-and-puff)--were carried out by soaking heavy oil saturated cores into a reactor filled with gas representing a matrix/fracture system. Oil recovery and O2 consumption were the main parameters assessed and an extensive set of variables including rock type, temperature, fracture volume, solvent type, matrix size, gas injection sequences, and soaking times were studied. From experimental studies, the following conclusions were made: 1.Gas sequence design affects oil recovery, 2.O2 consumption in air cycles is higher after the core is soaked into butane rather than propane, 3.It is beneficial to soak cores in air+C3 mixture rather than pure air or solvent; i.e., lower O2 concentration in produced gas, less solvent usage, higher and faster oil recovery compared to alternate injection of air and C3. Then, core scale numerical simulation models were created for modeling lab experiments for a sensitivity analysis on Air/C3 ratio and matrix size. The results show that the process is extremely sensitive to matrix size and optimization of air injection (assisted by hydrocarbon solvents) can be achieved based on the minimized hydrocarbon solvent for a given matrix size. Additionally, a sensitivity analysis was performed using an up-scaled numerical model to the field scale containing meter-scale matrix blocks. It was observed that oil production mechanisms acting in a matrix block surrounded by gas filling the fractures are predominantly gas-oil gravity drainage, effective diffusion, and voidage replacement of oil by gas. Finally, a numerical simulation sector model of a hypothetical NFR was created and several air-gas injection sequences were analyzed. It was concluded that injection of air (LTO conditions) and propane represents an alternative for heavy oil recovery from NFRs at the field scale, and an optimum production time/soaking time ratio can be obtained for given gas injection sequences (type of gas and injection/soaking durations), temperature, and block sizes.
