Today's economic environment dictates that decisions to make significant investments in field development, rehabilitation or improved recovery operations requires a detailed understanding of the reservoir in order to predict its behavior. We have conducted numerous large-scale reservoir studies involving multi-disciplinary teams that resulted in a full reservoir interpretation. Such studies integrate geophysics, geology, petrophysics, engineering and economics. We maintain state-of-the-art software to handle the multiple data formats and calculation requirements in order to maximize man time spent studying the reservoir and minimize time spent performing routine computations.
Reservoir simulation is a rapidly growing area of business for Scotia. Our simulation team has career length experience on projects around the world and is supported by the most comprehensive and up-to-date simulation models available to the industry.
Field scale simulation studies to support field development planning have been performed by team members in most of the world's producing regions, both onshore and offshore. Projects have included: black oil simulations of oil and gas field depletion, water and gas injection, improved recovery and polymer flooding; compositional simulations of volatile oil and rich gas condensate systems, miscible gas displacement and gas cycling; dual porosity and dual permeability simulations of naturally fractured and vugular carbonate reservoirs by depletion drive and improved recovery methods such as gas injection repressurization to reduce gas-oil interfacial tension for improved gravity drainage or water injection pressure maintenance to prevent fracture closure and improve oil displacement through imbibition.
We conducted a three-phase integrated study of a large field in Venezuela, South America. The first phase involved a comprehensive audit of the available field data to determine the feasibility of an integrated study. The second phase integrated geological, geophysical, petrophysical and reservoir engineering disciplines to make a detailed characterization of the reservoir. The third phase applied reservoir simulation using Eclipse Model to obtain projections of reservoir performance under several redevelopment scenarios.
We completed a series of reservoir screening studies that quantified remaining oil in-place and determined the potential for additional recovery using a variety of IOR methods. These studies also examined the economics of the various alternatives and developed recommendations for implementation.
As part of a multi-year Department of Energy project, we characterized and analyzed all tight overpressured gas reservoirs in the Greater Green River Basin. This included development of specialized techniques to correct core and log data so that reserves and productivity could be estimated. Scotia is one of the few firms that has the experience and analytical capability to properly evaluate tight gas reservoirs.
We conducted a coordinated geological and engineering study of a giant salt dome field in southern Louisiana involving several hundred reservoirs and over 1,500 completions. Recommendations for infield exploration, recompletions and attic drilling were developed.
It is recognized that detailed reservoir descriptions are the cornerstone of successful reservoir simulation projects. We have conducted numerous reservoir studies in support of feasibility projects through to full reservoir simulations.
Unconventional resources are becoming increasing contributors to domestic U.S. gas production. We have conducted several large-scale studies involving such reservoirs including tight gas, coalbed methane and gas from Devonian shales.
Our team members have conducted reservoir simulation projects involving waterflooding, CO2 miscible and other processes using black oil and compositional models.
