Society of Petroleum Engineers Disciplines 4. Formation damage can occur during the drilling baoud coring operations, well completion, workover and production. These wells are taken as an example to compare between treatment volumes obtained from laboratory results and those obtained using the rule of thumb.
Acidizing tests of 4 different acids are conducted and discussed to select the optimum fluids. ABB is responsible for design, engineering, procurement, commissioning and start-up.
Monitoring of Ground Deformation in the Haoud Berkaoui Oil Field (Sahara, Algeri
Matrix acidizing treatment is successful and economic when either no excess volume or insufficient volume is used. Geophysical Research Abstracts Vol. The ABB Group of companies operates in around berkaoki and employs aboutpeople. The most common reason of formation damage is the drilling operations. Rock Mechanics Symposium and 5th U. Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition.
Advanced search Show search help. Laboratory test results show permeability improvement for 3 systems. However; one system proposed to treat injection wells gave mediocre results. Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity.
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. ABB will also supply a complete LPG pumping station including all the electrical, piping and mechanical equipment. Beroaoui, 7 wells are selected on the basis of productivity impairment and are proposed for matrix acidizing.

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. The order was booked in the fourth quarter of 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.
Abstract The most common reason of formation damage is the drilling operations. Peer reviewed only Published between: Help Center Find new research papers in: The study of this incident helps in the understanding of the subsidence process and the mitigation bekraoui further underground collapse that may affect neighboring urban areas.
They affect the reservoir as pore blocking by solids, clay swelling and dispersion and liquid block which reduces effective permeability to hydrocarbons.
Located in the Sahara oil fields the Haoud Berkaoui is an important drill where numerous wells were open to extract oil starting from s. Visual observations of cores using SEM are also used as interpretation tools. Bougdal 3and M.

Proceedings of an international conference Diverless and Deepwater Techology: Publishers Content Coverage Privacy. Rules of thumb may not be convenient and always over estimate or underestimate the volume.
As the source of damage is known, berakoui types of acid systems are proposed by service companies to improve the near wellbore formation permeability.
ABB wins $100 million oil and gas order in Algeria
An elastic model with volume decrease is established to relate the surface subsidence to the dissolution-collapse at depth. However; the injection of an acid into the formation without precaution and preliminary study could cause severe damage.
