As the source of damage is known, different types of acid systems.

Therefore, it is convenient to proceed to a complete laboratory study before any treatment in the field.
ABB wins $100 million oil and gas order in Algeria
The order was booked in the fourth quarter of Contact us Page information:. Cakir 2R. The plant is scheduled for completion by March These wells are taken as an example to compare between treatment volumes obtained from laboratory results and those obtained using the rule of thumb. You must enter a message. Recently, Haoud Berkaoui field suffers mainly from formation damage related to drilling mud. Berksoui, 7 wells are selected on the basis of productivity berkaoyi and are proposed for matrix acidizing.

The determination of acid volume is complicated and is generally based on field experience or using rules of thumb. Rules of thumb may not be convenient and always over estimate or underestimate the volume. This system presents a good permeability improvement with less damaging precipitates and no risk of emulsion. Proceedings of an International Conference Submersible Technology: Log In Sign Up.
Publishers Content Coverage Privacy. The most common reason of formation damage is the drilling operations. Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in the direction to Ouargla city. Besides, optimum volume is predicted based on the laboratory acid response curves.
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. The ABB Group of berkaoii operates in around countries and employs aboutpeople. Please type one email address only.
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. Bouraoui 1Z.

Formation damage can occur during the drilling or herkaoui operations, well completion, workover and production. Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity.
Mud filtrate and fines invasion during drilling are the most important problems that affect petroleum reservoirs.
Matrix acidizing treatment is successful and economic when either no excess volume or insufficient volume is used. As the source of damage is known, different types of acid systems are proposed by service companies to improve the near wellbore formation permeability. Damage diagnostic shows also that corrosion products caused by anaerobic bacteria affect the injectivity of injection wells. You must enter one valid e-mail address. Advanced search Show search help. However; one system proposed to treat injection wells gave mediocre results.

ABB is responsible for design, engineering, procurement, commissioning and start-up. One of those method is “Matrix haoid which consists of injecting acids into the formation below fracturing pressure to eliminate the damage around the well.
Laboratory test results show permeability improvement for 3 systems. Visual observations of cores using SEM are also used as interpretation tools.
Different laboratory tests are conducted to evaluate Haoud Berkaoui rock characteristics as well as to evaluate the interaction between 4 types of acid and the rock for optimal selection.
We evaluate the possible propagation and the direction of the subsidence by studying the spatial temporal variation of subsidence together with the distribution of the other berkqoui wells in the same area.
Proceedings of an international conference Oceanology: Of these, OKN32 and OKN32BIS wells collapsed due to dissolution of evaporatic rocks resulting in rapid ground subsidence and eventually a spectacular crater m in diameter and 80 in deep today.
