This paper presents a new Green’s function-based type curves for analyzing rate transient data from multi-fractured horizontal wells in unconventional gas reservoirs. Type curve analysis has been extensively employed as an inverse modeling approach to determine key reservoir/hydraulic-fracture properties well original gas-in-place based on recorded production data. Several studies were conducte...

Paleostress plays a significant role in controlling the formation, accumulation, and distribution of reservoirs, this could be an important factor production hydrocarbons from unconventional reservoirs. In study, we will use 3D seismic reflection data to perform slip-tendency-based stress inversion determine field basement northern slope area Bongor Basin. The dataset for technique is easily av...

The state of the art of modeling fluid flow in shale reservoirs is dominated by dual porosity models which divide the reservoirs into matrix blocks that significantly contribute to fluid storage and fracture networks which principally control flow capacity. However, recent extensive microscopic studies reveal that there exist massive microand nanopore systems in shale matrices. Because of this,...

Tight sandstone reservoirs, as typical unconventional have attracted more and attention worldwide. Compared to conventional the complex microscopic pore structures micro-fractures of tight reservoirs are developed, fluid flow in reservoir is very complicated. Therefore, studying influence fractures on rock topological structure characteristics between matrix critical development reservoirs. In ...

Post-fracturing shut-in, as an important means of improving the energy efficiency fracturing fluid, has been widely used in development process unconventional reservoirs. The determination shut-in duration is key to effectiveness measures. However, distribution characteristics fluid during post-fracturing period reservoirs, such Chang 7 reservoir, were not clear, and needed further optimization...

Although gas desorption is a known phenomenon, modeling fluid flow in tight reservoirs often ignores the governing effect, assuming that viscous transport predominant controller, resulting an erroneous prediction of mass and calculations. Thus, developing new model accommodating all major contributing forces such medium essential. This work introduces comprehensive suitable for unconventional r...

Production profiling technology is an important method for monitoring the dynamics of oil and gas reservoirs which can effectively improve efficiency recovery. a technique in test instrument lowered from tubing to bottom well measure flow, temperature, pressure, density multi-layer section producing well. Normal production process needs stop production, operate complex, consume long time high c...

The drilling time data of gas logging are used to calculate drilling time ratio of the reservoir, and the total hydrocarbon data are used to calculate hydrocarbon contrast coefficient and to establish the drilling time ratio--hydrocarbon contrast coefficient crossplot. The standards of distinguishing the boundaries of hydrocarbon zones, hydrocarbonaceous water layers and dry layers are determin...
