A Relative Permeability Database/Toolkit

Relative permeability and capillary pressure data sets are key components in reservoir characterization, understanding reservoir behavior, and predicting recovery factors in EOR projects such as water floods. Relative permeability data are also a critical input parameter for reservoir simulators. The data are typically expensive to acquire and in many cases are not readily available, such as in: 1) old fields, 2) acquisition candidates, 3) fast-track reservoir simulation of discovery wells and 4) “unconventional” reservoirs such as ultra-low permeability sands and shales. In these cases, the petrophysicist or engineer is often left with his or her “best estimate” of residual oil, relative permeability, water cut curves, and recovery factors. The uncertainty and risk involved in making these estimates can be greatly reduced by having a relative permeability database that can be accessed to acquire the statistics and probability of these key parameters from reservoir-specific measurements and/or analogs. 

A Relative Permeability Database and associated Toolkit has been developed for the purpose of enhancing prediction of reservoir behavior. Accessing data sets stored in the database, users can search for analogs, including unconventional reservoirs, on multiple levels (Measurement Method, Sample State, Basin, Field, Country, Permeability Range and Porosity Range), optimize samples returned from the database (Corey-Type Coefficients, Initial and Residual Saturations, Adjustable Weighting Factors), average selected curves, incorporate drainage-cycle capillary pressure data to generate synthetic drainage-cycle rel perm curves for analysis of transition zones, generate waterflood performance evaluations and have the ability to export the results for use in simulators. User supplied data can also be included in the analysis. 

A review of basic relative permeability and capillary pressure concepts, along with examples of Water-Oil (imbibition-cycle) applications in conventional reservoirs and relative permeability determination in unconventional reservoirs, will be presented.

Experience

Allen is currently is responsible for world-wide marketing of Core Laboratories’ Data Management services (RIB, RAPID, RelK and Spotfire analytical solutions). Formerly he was the Manager of Core Laboratories’ Coastal Regions, which included the U.S. West Coast and Gulf Coast Petroleum Services operations, in which he oversaw operations in Alaska, California, the Texas Gulf Coast region and Louisiana.

His lectures and publications include topics ranging from data management and analytics to the correlation of pore geometry attributes with advanced rock property measurements. Allen has developed and presented numerous in-house schools on topics ranging from routine and special core analysis, unconventional reservoir analytics and reservoir analogs, to week-long fracture analysis schools.

Allen is a guest lecturer at Stanford University, the University of Oklahoma and Arkhangelsk State Technical University on petrophysical applications to log analysis as well as capillary pressure and relative permeability applications in reservoir evaluation. He is a member of AAPG (Honorary Lifetime Member of the Pacific Section AAPG), SPWLA and SPE.
