Shale Gas Productivity Prediction Model Considering Time-Dependent Fracture Conductivity

نویسندگان

چکیده

Conventional shale gas productivity prediction techniques consider fracture conductivity to be a fixed value, but in actual production processes, changes with time. Therefore, this paper proposed capacity method that considers time-dependent and validates its accuracy using commercial simulators. First, relevant parameters were obtained by fitting the improved long-term test, then seepage model was established EDFM method. The laboratory test results showed order of significance affecting retention rate fracturing fluid viscosity > sand concentration time; calculation show flow pressure curves corresponded constant variable some extent different. In presence complex fractures natural fractures, increase curve smaller than curve. This study provides guidance for field production.

A New Simulation Approach to Model Complex Fracture Networks in the Shale Formation Considering Gas Desorption

Hydraulic fracturing in shale gas reservoirs has usually resulted in complex fracture network. The results of micro-seismic monitoring showed that the nature and degree of fracture complexity must be clearly understood to optimize stimulation design and completion strategy. This is often called stimulated reservoir volume (SRV). In the oil & gas industry, stimulated reservoir volume has made th...

Intelligent fracture creation for shale gas development

Shale gas represents a major fraction of the proven reserves of natural gas in the United States and a collection of other countries. Higher gas prices and the need for cleaner fuels provides motivation for commercializing shale gas deposits even though the cost is substantially higher than traditional gas deposits. Recent advances in horizontal drilling and multistage hydraulic fracturing, whi...

How fracture interference impacts Woodford shale gas production

An integrated analysis of fracture interference revealed that hydraulic fracture system damage was, most likely, due to stimulation fluid flooding, into depleted fracture systems around parent wells, resulting in a reduction in the effective fracture area. The team proposed a number of options to mitigate the impact of fracture interference, including refracturing the existing producing well wi...

Impact of Stress-Dependent Matrix and Fracture Properties on Shale Gas Production

Unconventional shale gas production is often characterized by a short period of high production followed by a rapid decline in the production rate. Given the high costs of hydraulic fracturing and horizontal drilling, it is critical to identify the mechanisms behind the production loss. The existing shale gas production models often assume constant matrix permeability. However, laboratory obser...
