In recent work, data-driven sweet spotting technique for shale plays previously explored with vertical wells has been proposed. Here, we extend this technique to multiple formations and formalize a general data-driven workflow to facilitate feature extraction from vertical well logs and predictive modeling of horizontal well production. We also develop an experimental framework that facilitates...

The combined well pattern has been widely used in reservoir development, with a common being horizontal the center for oil production and multiple vertical wells around water injection. For this type of pattern, determining is affected by which injection wells, especially when injecting breaks through, accurately direction inflow will provide an important basis targeted measures. Based on perfo...

Based on the accurate understanding of reservoir, oil-water distribution and structure block A, main oil layers are locally developed in well blocks B C, favorable parts optimized, horizontal wells deployed according to principle “increasing production layer, not adding new platforms, section is easy be too long”. Apply drilling data carry out fine interpretation reservoir inversion prediction,...

A gas kick simulation model for deep-water horizontal well with diesel-based drilling fluid is presented in this paper. This model is mainly based on the mass, momentum, and energy conservation equations. The unique aspect of this model is the fluid-gas coupling and the change of mud properties after the gas influx from the formation. The simulation results show that the gas in an annulus disso...

recognition of relationship between the present day stress state and fractures is very important in fractured reservoirs. fractures that are parallel or oblique to maximum horizontal stress have more tendencies to tensile deformation and tensile deformed fractures will be more permeable. the dalan formation is one of the main gas reservoirs of iran witch most of the production from this formati...

in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...
