Revitalizing a mature oil play: Strategies for finding and producing unrecovered oil in Frio fluvial-deltaic reservoirs of South Texas. Technical progress report, July 1--September 30, 1995
Advanced reservoir characterization techniques are being applied to selected reservoirs in the Frio fluvial-deltaic sandstone trend in order to maximize the economic producibility of resources in this mature oil play. More than half of the reservoirs in this play have already been abandoned, and large volumes of oil may remain unproduced unless advanced characterization techniques are applied to define untapped, incompletely drained, and new pool reservoirs as suitable targets for near-term recovery methods. This project is developing interwell-scale geological facies models and assessing engineering attributes of reservoirs in selected fields in order to characterize reservoir architecture, flow unit boundaries, and the controls that these characteristics exert on the location and volume of unrecovered mobile and residual oil. Phase 1 consisted of reservoir selection and initial framework characterization. Phase 2 involved advanced characterization to delineate incremental resource opportunities. Subtasks included volumetric assessments of untapped and incompletely drained oil along with an analysis of specific targets for recompletion and strategic infill drilling. The third phase of the project consists of documentation of Phase 2 results, technology transfer, and the extrapolation of specific results from reservoirs in this study to other heterogeneous fluvial-deltaic reservoirs within and beyond the Frio play in South Texas. Project work during this quarter consisted of (1) documentation of Phase 2 tasks associated with the delineation of untapped and incompletely drained reservoir compartments and new pool reservoirs in selected Frio fluvial-deltaic sandstone intervals in Rincon and Tijerina-Canales-Blucher fields, as well as (2) Phase 3 tasks related to the transfer of the technologies to industry that aided in delineation.
