The productivity of oil wells may be improved by determining the value enhancing well and likely reasons or sources formation damage after has been recognized as underperforming. Oil improved, but economics this gradual improvement compromised. It is important to analyze influence skin effect on recovery reserve. acid treatment evaluated for AD-12, primarily zone Mi4; using a license Stimpro St...

Drilling and completion fluids may cause significant formation damage in oil gas reservoirs, directly affecting productivity. For many years, operators have applied different stimulation practices such as acidizing, oxidizers, chelating agents, enzyme treatment to remove associated with drilling filter cake. An enzyme-based biological was combined other chemicals or additives a selective well c...

Abstract The acidizing approach belongs to the well workover operations, where acid mixtures are initially implemented treat damage near wellbore area after drilling operations have been completed. Acidizing treatment is characterized by removal of fine particles and debris from porous media damaged zone, hence leading improve oil production wells. This study evaluates assessment in vertical oi...

Oil well acidizing, although a stimulation process, induces the corrosion of metallic equipment and tubing. There is, at present, high demand for effective less toxic high-temperature inhibitors acidizing process due to failing existing temperatures occasioned by increases in depths. In this study, aspartame (ASP), commercially available natural compound, is examined as inhibitor T95 carbon ste...

Eco-friendly inhibitors are an alternative to reduce environmental and human health problems related conventional employed in oil well acidizing. In the present study, boldo (Peumus boldus) was investigated as a corrosion inhibitor for API P110 carbon steel 2 M 15% HCl. A two-level full factorial design (23) used evaluate extraction time (90 210 min), temperature (313 343 K) solute/ethanol rati...

Matrix acidizing in carbonate reservoirs is a process that has been long used to increase productivity oil and gas producing formations. The main goal create wormholes bypass the damage formation. Hydrochloric acid (HCl) for this; however, it several disadvantages affect success of these treatments. Its high reaction rate, inability divert, corrosive nature are few reasons why research this are...

An effective diversion technique is a crucial component in all acid stimulation jobs, which allows us to achieve full zonal coverage and thereby the treatment objectives. In process of acidizing heterogeneous formations, it necessary change direction fluid target interval, i.e., interval with low permeability, ensure an even distribution pumped fluids throughout formation. This because due diff...

Acidizing is a widely adopted approach for stimulating carbonate reservoirs. The two-scale continuum (TSC) model the most used simulating reactive process in reservoir during acidizing. In realistic cases, there are overburden pressure and pore at present. When injected acid reacts with rock, dissolution of rock consumption will break mechanical balance rock. Many experimental studies show that...
