Excessive water production is one of the main problems of mature reservoirs, which reduces
hydrocarbon production and economic reservoir lifetime, and may pose severe …

This paper explores matrix acidizing, a method to enhance well productivity by injecting acid
into the formation to dissolve damage or create flow channels. Focusing on gas well …

The influence of organic acids (formic acid, acetic acid) on the corrosion behaviour of 110SS
steel, a hydrogen sulphide corrosion resistant alloy steel, in hydrochloric (HCl) acid …

The economic development of tight carbonate reservoirs requires hydraulic or acid fracturing
stimulation. Acid fracturing better activates natural fractures, resulting in increased …

As exploration and development to the ultra-deep layer continue to advance, bottom hole
temperatures have gradually increased, aggravating acid corrosion of the downhole pipe …

Abstract pH-sensitive microgel flooding is a deep conformance control technique in which
the microgel viscosity depends on formation pH. Lowering the formation pH by an acid pre …

Matrix acidizing is a well stimulation process in which acid is introduced into the reservoir
near the wellbore area via the wellbore or coil tubing. In the oil industry, formation damage is …

Roof disaster has always been an important factor restricting coal mine safety production.
Acidic effect can reform the rock mass structure to weaken the macroscopic strength …

The Sebei gas field is in the Sanhu depression area of the Qaidam Basin, which is the main
gas-producing area and a key profit pillar for the Qinghai oilfield. The Sebei gas field within …

To improve the efficiency of standard hydrochloric acid (HCl) stimulation treatments, many
alternative acid systems have been developed to mitigate corrosion, increase wormhole …
