Stress Sensitivity of Proppant-Containing Fractures and Its Influence on Gas Well Productivity

open access: yesGeofluids, 2023
Formation pressure gradually decreases with fracturing fluid flowback and gas production. Due to the stress sensitivity of the fractures, the permeability of the artificial fractures after fracturing becomes lower, which significantly affects gas well ...

Method to Predict Proppant flowback in Fractured Gas well [PDF]

open access: yesProcedia Environmental Sciences, 2012
AbstractIt has influences on the production of gas well and the effects of fracture when proppant flowback in the fractured gas well and the loss of the proppant from the fracture will corrupt the equipment above and below ground. For the problem of proppant flowback in fractured gas well, the purpose of this paper is to building a model of predict the

HYDRAULIC FRACTURING DESIGN IMPROVEMENTS BY PROPPANT FLOWBACK MITIGATION METHOD APPLICATION DURING HYDROCARBON PRODUCTION [PDF]

open access: yesRudarsko-geološko-naftni Zbornik, 2021
Proppant flowback after hydraulic fracturing treatment is quite a serious challenge that causes damage to both downhole and surface equipment, leading to unwanted workovers and production suspension, or other negative outcomes.

Feasibility of Proppant Flowback Control by Use of Resin-coated Proppant [PDF]

open access: yesJournal of Basic & Applied Sciences
Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs. Curable resin-coated sand is a common technique to control proppant flowback.

Numerical Simulation of Choke Size Optimization in a Shale Gas Well

open access: yesGeofluids, 2022
To optimize the flowback system of shale gas horizontal wells after fracturing and to maximize the production capacity of gas wells, pipe flow and flowback models of shale gas multistage fractured horizontal wells were established based on the actual ...
