Acid fracturing is the most commonly used acid treatment technology in carbonatite reservoir stimulation operations. Acid is squeezed into the reservoir under a pressure higher than …

2020年3月1日 · The purpose was to investigate the optimum acid fracturing design that leads to a higher fracture etched length and width, and higher fracture conductivity. Moreover, the impact …

2021年12月1日 · Acid fracturing is an important means of reservoir stimulation, whose purpose is to form an incompletely closed acid-etched fracture as the flow channel for oil and gas during …

Fracture acidizing is a hydraulic fracturing treatment for carbonateformations in which acid-etched channels serve as very-high-conductivity flowpaths along the face of the fracture. HC1 of 15 to …

2006年9月24日 · Acid fracturing is performed to improve well productivity in acid-soluble formations such as limestone, dolomite, and chalk. Hydrochloric acid is generally used to …

2021年3月1日 · Acid fracturing is one of the key technology for development of such naturally fractured-vuggy reservoirs. Mud overflow and loss may be emerged at the same time while …

2023年4月4日 · Based on the formed organic acid system, the acid–rock reaction kinetics, retarding performance, and conductivity were evaluated. The self-generating organic acid …

2018年10月16日 · The workflow presented in this paper provides the basis for designing optimum acid fracturing treatments as a function of the volume of acid injected, the acid injection rate …

2024年2月20日 · An integrated model for acid fracturing without prepad treatment has been established. Compared with the previous models which use prepad for generating hydraulic …

2016年5月30日 · In this study, a procedure is developed to evaluate the feasibility of acid fracturing by comparing conductivity generated from an unpropped fracture, a propped fracture …
