As the source of damage is known, different types of acid systems are proposed by service companies to improve the near wellbore formation permeability. Bouraoui 1Z.

This system presents a good permeability improvement with less damaging precipitates and no risk of emulsion. Bougdal 3and M. The present study includes a methodology that will lead to improve matrix acidizing treatment starting by laboratory experiments to prevent acid-rock interaction and to predict treatment volumes. One of those method is “Matrix acidizing” which consists of injecting acids into the formation below fracturing pressure to eliminate the damage around the well.

Proceedings of an international conference Subsea Controls and Data Acquisition ‘ Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity.

Laboratory test results show permeability improvement for 3 systems. Damage diagnostic shows also that corrosion products caused by anaerobic bacteria affect the injectivity of injection wells. 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 oil wells in the same area.


Remember me haud this computer. In the life of a well, its productivity or injectivity is affected by formation damage which is an undesirable technical and economic problem. Publishers Content Coverage Privacy. 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.

Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Proceedings of an international conference Oceanology: They affect the reservoir as pore blocking by solids, clay swelling and dispersion and liquid block which reduces effective permeability to hydrocarbons.

Bedkaoui one system proposed to treat injection wells gave mediocre results. An elastic model with volume decrease is established to relate the surface subsidence to the dissolution-collapse at depth. Press releases Group press releases. About us Contact us Help Terms of use.

The ABB Group of companies operates in around countries and employs aboutpeople. Moreover, 7 wells are selected on the basis of productivity impairment and are proposed for matrix acidizing. ABB is responsible for design, engineering, procurement, commissioning and start-up.

Proceedings of an International Conference Submersible Technology: Acidizing tests of bwrkaoui different acids are conducted and discussed to select the optimum fluids. Rock Mechanics Symposium and 5th U.

Contact us Page information:. Visual observations of cores using SEM are also used as interpretation tools.

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 hakud today. Proceedings of an international conference Diverless and Deepwater Techology: The determination of acid volume is complicated and is generally based on field experience or using rules of thumb. Mud filtrate and fines invasion during drilling are the most important problems that affect petroleum reservoirs.


Zurich, Switzerland, June 19, — ABB, the leading power and automation technology group, has been awarded the engineering, procurement and construction EPC contract for a new liquefied petroleum gas LPG pumping station in berksoui Hassi Messaoud District to increase the capacity of LR1 pipeline in Algeria.

Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in berkoui direction to Ouargla city. Cookies and privacy policy Login. Society of Petroleum Engineers Disciplines 4.

Matrix acidizing treatment is successful and economic when either no excess volume or insufficient volume is used. You must enter one valid e-mail address.

ABB will also supply a complete LPG pumping station including all the electrical, piping and mechanical equipment. Abstract The most common reason of formation damage is the drilling operations. Besides, optimum volume is predicted based on the laboratory acid response curves. Log in to your subscription Username. Recently, Haoud Berkaoui field suffers mainly from formation damage related to drilling mud. Cakir 2R.
