16811 – Open Hole Multistage Completion Exceeds Production Expectations from South Sulige Gas Field in China

Summary

The South Sulige field in China is a tight gas sandstone reservoir made up of two low permeability and low porosity formations. Exploration of the field began in 2007, from which point a total of 16 stages were fractured among five vertical cased hole wells. The production results were not impressive, with the exception of one well. A joint venture project in this field began its development phase in 2011 with the intent of evaluating horizontal drilling and open hole multistage (OHMS) fracture stimulation. A total of five wells to date have been stimulated with OHMS completions and well performance has exceeded expectations. This paper discusses the overall enhanced well performance achieved using zonal isolation and open hole stimulation.
