Abstract

AbstractShale reservoirs comprise the source rock, which seal the reservoir and production is stimulated through hydraulic fracturing treatments. The economic productivity prediction and optimal fracture stimulation design is based on integrated petrophysical evaluation.Integrated petrophysical evaluation shale gas integrates different types of data, including standard full-set logs, geochemical logs and advanced acoustic logs. These data, when combined together provides better answers about quality of the shale gas reservoirs.The reservoir quality is established from conventional formation evaluation log (full-set logs) and geochemical logs, which include TOC, NMR porosity and mineralogy of gas in place. In this new integrated petrophysical evaluation method, elemental capture spectrometry log (ECS) and advanced acoustic measurements (DSI) are the keys for estimating reservoir dynamic properties.KeywordsShalegasEvaluation
