... Abstract Marine fractured-vuggy carbonate reservoirare important oil and gas reservoirs in China, the Middle East, and North America. In the development process, it is necessary to connect hydraulic fractures and as many karst cavities as possible, which are the main geological components...

... Abstract The productivity and injectivity of hydraulically fractured geothermal wells in naturally fractured formations depends on the connectivity of fracture networks created by the interaction of hydraulic fractures with natural fractures. The primary objectives of this paper...

... Abstract In this paper, a workflow is proposed to investigate fracture morphology in shale formations, integrating two parts: forward simulation and backward calibration. Uncertainty in the forward simulation should be quantified by backward calibration, in order to get the efficient simulation...

... resources. Carbonate reservoirs provide a unique set of formation and productivity evaluation related challenges due to the highly variable characteristics of the natural fractures. This work elucidates how production logging data, combined with multiple wireline logs, resulted in resolving water production...

... Abstract The quantitative understanding of HF properties guides accurate production forecasts and reserve estimation. Type curve is a powerful technique to characterize hydraulic fracture (HF) and reservoir properties from flowback and long-term production data. However, the two-phase flow...

... equations for flow and heat transport in heterogeneous reservoirs with fractures. The results from reservoir modeling can assist engineers and executives in the decision-making process. A few geothermal reservoir simulation codes have been developed in the past several decades. The first generation...

... Abstract The cluster spacing was considered up to 700 ft in Barnett and Bakken shale formations. At this time, tight cluster spacing has been used up to 15 ft apart in Eagle Ford and DJ Basin. The drive for applying tight fracture spacing is to increase the initial production rate. However...

... in the Krisna Field experienced severe mud losses while drilling, which had caused significant invisible non-productive time (NPT). The losses were associated with potential natural fracture swarms in the limestones and basement formations, but the fracture apertures were below the resolution of the LWD density...

... Abstract Shale gas reservoirs in the LongMaxi Formation, Sichuan Basin, are the biggest proven shale gas reservoirs in China. The natural fracture system plays an important role in the shale gas exploration and development. Both high-angle calcite-cemented fractures and low-angle bedding...

Deccan Trap acts as reservoirs due to the presence of connected open fracture network and to assess the potential reserves a comprehensive 3D Critically stressed fracture analysis has been performed using 3D numerical simulation-based rock properties, in-situ stress...

...Introduction Tight sandstones formations are the important oil and gas resource for China, which are rich at Sichuan basin and Tarim basin. Low porosity and permeability, high rock density, and deeply buried require perforated fracturing to achieve the formation stimulation. Perforations offer...
