WebGiven the complex nature of hydraulic-fracture growth and the very low permeability of the matrix rock in many shale gas reservoirs, ... Predicting Shale Reservoir Response to … WebOct 19, 2024 · Shale gas is an important unconventional energy resource that needs large-scale fracturing to form industrial deliverability. The evaluation of reservoir fracability plays a key role in the optimization of the sweet spot, the design of multistage fracturing, and the prediction of economic benefit. Based on volumetric fracturing, the study proceeded from …
Effects of Hydration during Drilling on Fracability of Shale Oil ...
WebFracability is a measure of the difficulty of a shale reservoir to be effectively reformed and indicates whether a reservoir may produce a larger reformed volume by fracturing [13, 14]. Chong et al. proposed the concept of using brittleness index (BI) as a norm to evaluate the fracturing ability of shale reservoirs. WebFeb 2, 2015 · Summary. The identification of the fracture barrier is important for optimizing horizontal-well drilling, hydraulic fracturing, and protecting fresh aquifer from contamination. The word “brittleness” has been a prevalent descriptor in unconventional-shale-reservoir characterization, but there is no universal agreement regarding its definition. Here, a new … mariposa county hiking death
