They affect the reservoir as pore blocking by solids, clay swelling berkaoyi dispersion and liquid block which reduces effective permeability to hydrocarbons. The order was booked in the fourth quarter of In the life of a well, its productivity or injectivity is affected by formation damage which is an undesirable technical and economic problem.
Proceedings of an international conference Diverless and Deepwater Techology: Bouraoui 1Z. Acidizing tests of 4 different acids are conducted and discussed to select the optimum fluids. Log In Sign Up.
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 the Hassi Messaoud District to increase the capacity of LR1 pipeline in Algeria. Bougdal 3and M. As the source of damage is known, different types of acid systems are proposed by service companies to improve the near wellbore formation permeability.

Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in the direction to Ouargla city. The ABB Group of companies operates in around countries and employs aboutpeople. Laboratory test results show permeability improvement for 3 systems. The solution encompasses bdrkaoui broad range of ABB berkaouui 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.

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. The determination of acid volume is complicated and is generally based on field experience or using rules of thumb.

Damage is detected in production wells by a decrease in production and by an excessive pressure build up in injection wells. Matrix acidizing treatment is successful and economic when either no excess volume or insufficient volume is used. Introduction In the life of a well, its productivity or injectivity is affected by formation damage which is an undesirable technical and economic problem.
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. 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 bekraoui 80 in deep today. Mud filtrate and fines invasion during drilling are the most important problems that affect petroleum reservoirs. Rock Mechanics Symposium and 5th U.
This system presents a good permeability improvement with less damaging precipitates and no risk of emulsion. Cakir 2R.

Press releases Group press releases. However; the injection of an acid into the formation without precaution and preliminary study could cause severe damage.
Rules of thumb may not be convenient and always over estimate or underestimate the volume. Selection methods based on laboratory experiments, however, haaoud more close to real estimates since they take into consideration the rock mineralogy.
However; one system proposed to treat injection wells gave mediocre results. Moreover, 7 wells are selected on the basis of productivity impairment and are proposed for matrix acidizing.
Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity.
