Abstract There are many factors which influence the absolute open flow potential (AOFP) of gas well. One them is angle between maximum principal stress direction and natural fracture strike in reservoir. In order to find out how influences AOFP A lot data related well productivity 14 wells located reservoir T were collected collated. Influential intensity each factor on before after modificatio...

Data-space inversion (DSI) is a data assimilation procedure that directly generates posterior flow predictions, for time series of interest, without calibrating model parameters. No forward simulation performed in the process. DSI instead uses prior generated by performing O(<m...

Total compressibility in a fractured reservoir is estimated using the pressure response due to gravitational potential variations. Both the lunar and the solar gravitational potentials are fully accounted for by inclusion of longer-period components. The semidiurnal and diurnal pressure data show substantial long-term variations. The gravitational potential also contains the same variation tren...

A program was designed to allow the study of the effects of several parameters on the injection of water into and production of fluid from a fractured low porosity geothermal reservoir with properties similar to those at The Geysers. Fractures were modeled explicitly with low porosity, high permeability blocks rather than with a dual-porosity formulation to gain insight into the effects of sing...

Fractured-vuggy reservoirs are a new target in carbonate oil and gas exploration development. Because of well-developed reservoir bodies, including fractures caverns, bottom water invasion can be observed oilfield development, with low utilization efficiency crude the reservoir. Accordingly, this study focused on intersection region S99 unit Tahe fractured-vuggy reservoirs. Based seismic data, ...
