The unconsolidated sandstone is a type of rock that has poor cementation, low strength, high porosity, and permeability. It highly compressible under stress exhibits non-linear plastic deformation during hydraulic fracturing construction in its reservoir. In this study, the mechanical properties with different permeability were studied, three-dimensional fracture propagation numerical model was...

Tight hydrocarbon reservoirs require stimulation to improve the recovery of oil and gas resources. Hydraulic fracturing is a technique extensively employed in industry generate fractures including primary secondary fractures. To keep these open, proppants are used. However, some ractures very narrow for conventional penetrate prop, hence smaller called micro-proppants required. These can hydrau...

The feasibility of a normal perforating operation depends on the tubing string, which is main component cluster tool for exploration and development unconventional oil&gas reservoirs. To improve efficiency perforation in horizontal wells, passing capability analysis model string wellbore was established, thereby generating complex equations with coefficients that are solved via geometric an...

The pore structure can affect the storage and flow properties of rock, which is an important research content in study unconventional tight reservoirs. This hopes to clarify reservoir characteristics fluid seepage mechanism Chang 9 Wucangpu block provide technical support for development horizontal wells with staged fracturing this block. In paper, microscopic producibility area are analyzed de...

Turbidite fans, serving as good reservoirs for petroleum accumulation, are typically formed during deep faulting periods in continental basins, particularly steep slope zones. However, gentle zones also significant and unique the formation of turbidite fans. These fans hold immense importance exploring concealed lithological reservoirs. Taking Chezhen Depression Bohai Bay Basin an example, we c...

Core analysis provides the essential information necessary for characterization and development of hydrocarbon reservoirs. High core-scale heterogeneity anisotropy, natural in unconventional reservoirs, complicate reservoir dictate sampling methodology used. Continuous high-resolution thermal measurements with an optical scanner scratcher along core column can yield benefits a strategy. This ar...
