Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after acidizing. To understand the acidizing effect on reservoir rock, the formation rock is analyzed on different scales. An acidizing laboratory te...

Oil well are periodically acidized for enhancing oil flow. Inhibited hydrochloric acid is used during acidization to prevent corrosion of N80 or J55 steel. In the present work authors have surveyed literature on acidizing corrosion inhibitors and the salient features of research work carried out by the authors have also been highlighted.

Deepwater GWK-8 is a gas well in deep sea with 1500 meters water depth and deviated sandstone formation that has good permeability, potentially high-rate well, high reservoir pressures, large size. This expected to immediately ramp up production at optimal productivity through Floating Production Storage Offloading (FPSO) Makassar Strait. For deep-water exploration must be commercially viable, ...

Acidizing is a dissolving activity, whether it rock formations or other materials (natural foreign) in reservoir of the rock. To maintain production Jatibarang field, especially Bangodua (BDA) structure, there are 1 well that have experienced short decline since drilling. The properties not good and impurity material (damage). Thus, requiring stimulation form matrix acidizing. Evaluation acid w...

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...

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...
