This system presents a good permeability improvement with less damaging precipitates and no risk of emulsion. You must enter a message.
Visual observations of cores using SEM are also used as interpretation tools.
Besides, optimum volume is predicted based on the laboratory acid response curves. Bouraoui 1Z. 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.
Berkaaoui, 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 berkzoui station in the Hassi Messaoud District to increase the capacity of LR1 pipeline in Algeria.
ABB is responsible for design, engineering, procurement, commissioning and start-up. Selection methods based on laboratory experiments, however, are more close to real estimates since they take into consideration the rock mineralogy. Proceedings of an international conference Oceanology: Please type one email address halud.

They affect the reservoir as pore blocking by solids, clay swelling and dispersion and liquid block which reduces effective permeability to hydrocarbons. Laboratory test results show permeability improvement for 3 systems. Of these, Beroaoui 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.
Advanced search Show search help. These wells are taken as an example to compare between treatment volumes obtained from laboratory results and those obtained using the hapud of thumb.
An elastic model with volume decrease is established to relate the surface subsidence to the dissolution-collapse at depth.
Skip to main content. Matrix acidizing treatment is successful and economic when either no excess volume or insufficient volume is used.
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity. 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.
ABB will also supply a complete LPG pumping station including all the electrical, piping and mechanical equipment. 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. The order was booked in the fourth quarter of Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in the direction to Ouargla city.
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. Society of Petroleum Engineers Disciplines 4. 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.
Publishers Content Coverage Privacy. Recently, Haoud Berkaoui field suffers mainly from formation damage related to drilling mud.
ABB wins $100 million oil and gas order in Algeria
Formation damage can occur during the drilling or coring operations, well completion, workover and production. Geophysical Research Abstracts Vol.
Located in the Sahara oil fields the Haoud Berkaoui is an important drill where numerous wells were open to extract oil starting from s. 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. Rock Mechanics Symposium and 5th U.
