Mud filtrate brkaoui fines invasion during drilling are the most important problems that affect petroleum reservoirs. The order was booked in the fourth quarter of However; the injection of an acid into the formation without precaution and preliminary study could cause severe damage.
Rock Mechanics Symposium and 5th U. Introduction In the life of a well, its productivity or injectivity is affected by formation damage which is an undesirable technical and economic problem. ABB is responsible for design, engineering, procurement, commissioning and start-up.

Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in the direction to Ouargla city. The determination of acid volume is complicated and is generally based on field experience or using rules of thumb. In the life of a well, its productivity or injectivity is affected by formation damage which is an undesirable ebrkaoui and economic berkaoul.
An elastic model with volume decrease is established to relate the surface subsidence to the dissolution-collapse at depth.

Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity. Different laboratory tests are conducted to evaluate Haoud Berkaoui rock characteristics as well as to evaluate the interaction berkaui 4 types of acid and the rock for optimal selection. Peer reviewed only Published between: The ABB Group of companies operates in around countries and employs aboutpeople. Proceedings of an International Conference Submersible Technology: The solution encompasses a broad range of ABB power and automation products and systems including switchgear, transformers, motors, variable speed drive systems, instrumentation, distributed control and safety systems, as well as a supervisory control and data acquisition SCADA system for the new km pipeline.
The most common reason of formation damage is the drilling operations. Help Center Find new research papers in: Log In Sign Up.
Skip to main content. The study of this incident helps in the understanding of the subsidence process and the mitigation of further underground collapse that may affect neighboring urban areas. Geophysical Research Abstracts Vol. They affect the reservoir as pore blocking by solids, clay swelling and dispersion and liquid block which reduces effective permeability to hydrocarbons.
Therefore, it is convenient to proceed to a complete laboratory study before any treatment in the field. Visual observations of cores using SEM are also used as interpretation tools. These wells are taken as an example to compare between treatment volumes obtained from laboratory results and those obtained using the rule of thumb. Please type one email address only.

Selection methods based on laboratory experiments, however, are more close to real estimates since they take into consideration the rock mineralogy. This system presents a good permeability improvement with less damaging precipitates and no risk of emulsion.
As the source of damage is known, different types of acid systems are proposed by service companies to improve the near wellbore formation hoaud. Publishers Content Coverage Privacy. However; one system proposed to treat injection wells gave mediocre results.
Press releases Group press releases. Located in the Sahara oil fields the Haoud Berkaoui is an important drill where numerous wells were open to extract oil starting from s.
