Understanding Hydraulic Fracture Growth in Tight Oil Reservoirs by Integrating Microseismic Mapping and Fracture Modeling

摘要

In this case study, fracture treatments in three tight-oilrnreservoirs in the giant Ordos basin of northern China wererninvestigated using microseismic mapping and fracturernmodeling techniques to understand hydraulic fracture growthrnbehavior and post-frac performance. Reservoirs of interestsrnconsist of stacked fluvial sand/shale deposits, and the targetrnpay zones occur at depths between 1,820 and 2,186 meters.rnAll wells in these tight reservoirs require fracture stimulationrnto improve productivity. This paper provides a brief summaryrnof reservoir characteristics, but focuses on microseismicrnmapping results and fracture modeling analysis. This paperrndemonstrates that integrated studies can help engineersrnunderstand fracture behavior.
