Shear-slip analysis in multiphase fluid-flow reservoir engineeringap plications using TOUGH-FLAC

Description: This paper describes and demonstrates the use of the coupledTOUGH-FLAC simulator for geomechanical shear-slip (failure) analysis inmultiphase fluid-flow reservoir-engineering applications. Two approachesfor analyzing shear-slip are described, one using continuum stress-strainanalysis and another using discrete fault analysis. The use of shear-slipanalysis in TOUGH-FLAC is demonstrated on application examples related toCO2 sequestration and geothermal energy extraction. In the case of CO2sequest… more

Time-dependent seismic tomography of the Coso geothermal area, 1996-2004

Description: Local-earthquake tomographic images were calculated for each of the years 1996 - 2004 using arrival times from the U.S. Navy’s permanent seismometer network at the Coso geothermal area, California. The results show irregular strengthening with time of the wave-speed ratio VP/VS at shallow depths. These changes result predominately from progressive relative increase in VS with respect to VP, and could result from processes associated with geothermal operations such as decrease in fluid pressure … more

Analysis of real-time reservoir monitoring : reservoirs, strategies, & modeling.

Description: The project objective was to detail better ways to assess and exploit intelligent oil and gas field information through improved modeling, sensor technology, and process control to increase ultimate recovery of domestic hydrocarbons. To meet this objective we investigated the use of permanent downhole sensors systems (Smart Wells) whose data is fed real-time into computational reservoir models that are integrated with optimized production control systems. The project utilized a three-pronged ap… more

A Framework to Design and Optimize Chemical Flooding Processes

Description: The goal of this proposed research is to provide an efficient and user friendly simulation framework for screening and optimizing chemical/microbial enhanced oil recovery processes. The framework will include (1) a user friendly interface to identify the variables that have the most impact on oil recovery using the concept of experimental design and response surface maps, (2) UTCHEM reservoir simulator to perform the numerical simulations, and (3) an economic model that automatically imports th… more

BOAST 98-MC: A Probabilistic Simulation Module for BOAST 98

Description: This work was performed by Advanced Resources International (ARI) on behalf of the United States Department of Energy (DOE) in order to develop a user-friendly, PC-based interface that couples DOE's BOAST 98 software with the Monte Carlo simulation technique. The objectives of the work were to improve reservoir management and maximize oil recoveries by understanding and quantifying reservoir uncertainty as well as improving the capabilities of DOE's BOAST 98 software by incorporating a probabil… more

Mineral-Surfactant Interaction for Minimum Reagents Precipitation and Adsorption for Improved Oil Recovery

Description: In this project, fundamental studies were conducted to understand the mechanisms of the interactions between polymers/surfactants and minerals with the aim of minimizing chemical loss by adsorption. The effects of structures of the surface active molecules on critical solid/liquid interfacial properties such as adsorption, wettability and surface tension in mineral/surfactant systems were investigated. The final aim is to build a guideline to design optimal polymer/surfactant formula based on t… more

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma

Description: West Carney field--one of the newest fields discovered in Oklahoma--exhibits many unique production characteristics. These characteristics include: (1) decreasing water-oil ratio; (2) decreasing gas-oil ratio followed by an increase; (3) poor prediction capability of the reserves based on the log data; and (4) low geological connectivity but high hydrodynamic connectivity. The purpose of this investigation is to understand the principal mechanisms affecting the production, and propose methods b… more

Correlating laboratory observations of fracture mechanical properties to hydraulically-induced microseismicity in geothermal reservoirs.

Description: To date, microseismicity has provided an invaluable tool for delineating the fracture network produced by hydraulic stimulation of geothermal reservoirs. While the locations of microseismic events are of fundamental importance, there is a wealth of information that can be gleaned from the induced seismicity (e.g. fault plane solutions, seismic moment tensors, source characteristics). Closer scrutiny of the spatial and temporal evolution of seismic moment tensors can shed light on systematic cha… more
