Gas-prospective area optimization for Silurian shale gas of Longmaxi Formation in southern Sichuan Basin, China

摘要: AbstractWe investigated the development of a new criterion to quantify and rank marine shale reservoirs Lower Silurian Longmaxi Formation identify most prospective area in southern Sichuan Basin by examining correlation various parameters forming regionally consistent set. These reliable our model included geologic factors (rock properties), engineering brittleness, situ stress, pressure gradient), topographic (pipeline availability land accessibility). In addition common (thickness, depth, porosity, gas place), system used some critical associated with complex tectonic evolution preservation detail, such as gradient, conditions. An integrated data set was for designing well trajectory, creating large volume-induced fractures networks, increasing initial production gas. Our approach cl...
