Naturally fractured tight gas reservoir detection optimization. Quarterly Status211 Report. Period of Performance: January 1-March 31, 1999

摘要

In March, work continued on characterizing probabilities for determining natural211u001efracturing associated with the GGRB for the Upper Cretaceous tight gas plays. 211u001eStructural complexity, based on potential field data and remote sensing data was 211u001ecompleted. A resource estimate for the Frontier and Mesa Verde play was also 211u001ecompleted. Further, work was also conducted to determine threshold economics for 211u001ethe play based on limited current production in the plays in the Wamsutter Ridge 211u001earea. These analyses culminated in a presentation at FETC on 24 March 1999 where 211u001equantified natural fracture domains, mapped on a partition basis, which establish 211u001esweet spot probability for natural fracturing, were reviewed. That presentation 211u001eis reproduced here as Appendix 1. The work plan for the quarter of January 1, 211u001e1999--March 31, 1999 comprised five tasks: (1) Evaluation of the GGRB partitions 211u001efor structural complexity that can be associated with natural fractures, (2) 211u001eContinued resource analysis of the balance of the partitions to determine areas 211u001ewith higher relative gas richness, (3) Gas field studies, (4) Threshold resource 211u001eeconomics to determine which partitions would be the most prospective, and (5) 211u001eExamination of the area around the Table Rock 4H well.
