Western cretaceous coal seam project evaluation of coalbed natural gas openhole cavity completion productivity. Topical report, November 1990-December 1991
The evaluation of the reasons for the observed performance of two wells completed with openhole cavity technology is discussed. The wells are located at the Completion Optimization and Assessment Laboratory (COAL) Site operated by Amoco Production Co. and the Vertical COAL Site operated by Arco Oil Gas Co. Both wells are completed in the Fruitland Formation of the San Juan Basin of Colorado. The following conclusion resulted from the efforts. The cavity completion effectively links the well with the natural fracture system of the reservoir. Increased fluid productivity is due to increased linking rather than enhancement of reservoir properties. The cavity itself accounts for only 60% of the productivity increase and not the seven-fold increase in total fluid productivity.
