GRANITE WASH GEOLOGICAL, PETROPHYSICAL AND COMPLETIONS STUDY FOR IMPROVED FORMATION EVALUATION AND OPTIMAL WELL COMPLETIONS - Available in RAPID
The objective of this project is to optimize operators' exploitation of Granite Wash reservoirs in the Texas panhandle area and Oklahoma. Common problems in the trend are: formation evaluation, well completion, stimulation and production aspects of Granite Wash reservoirs.
These problems can only be solved from the geological, petrophysical and completion/stimulation analysis and evaluation of wells with either conventional cores or rotary sidewall cores. Twelve (12) wells with core were thoroughly analyzed geologically and petrophysically, including competion/stimulation analysis. The resultant data has been used to calibrate open-hole logs in order to better predict rock types and petrophysical properties essential for formation evaluation and proper well completion and stimulation designs. The rock types and their measured petrophysical properties also serve as analogs when evaluating new reservoirs in wildcats or field step outs.
This data has also been utilized to produce optimum fracture stimulation designs and to maximize productivity. A systematic approach to well evaluation, pre-stimulation testing, treatment design and optimum production practices have been developed to optimize the exploitation of the Granite Wash reservoirs. The study data was also used to benchmark well performance in terms of completion efficiency and reservoir quality in the study wells and serve as case histories for other Granite Wash potential plays.
