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.

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.
Formation damage can occur during the drilling or coring operations, well completion, workover and production. Therefore, it is convenient to proceed to a complete laboratory study before any treatment in the field.
The solution encompasses a broad range of ABB power 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. Zurich, Switzerland, Yaoud 19, — ABB, the leading power and automation technology group, has been awarded the engineering, procurement and construction EPC beerkaoui for a new liquefied petroleum gas LPG pumping station in the Hassi Messaoud District to increase the capacity of LR1 pipeline in Algeria.
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Press releases Group press releases. 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.
Society of Petroleum Engineers Disciplines 4. Peer reviewed only Published between: Selection methods based on laboratory experiments, however, are more close to real estimates since they take into consideration the rock mineralogy. You must enter one valid e-mail address. 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.
Advanced search Show search help. They affect the reservoir as pore blocking by solids, clay swelling and dispersion and liquid block which reduces effective permeability to hydrocarbons. Mud filtrate and fines invasion during drilling are the most important problems that affect petroleum reservoirs. 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 order was booked in the fourth quarter of Click here to sign up. Contact us Page information:. Help Center Find new research papers in: Cakir 2R. Moreover, 7 wells are selected on the basis of productivity impairment and are proposed for matrix acidizing. Damage is detected in production wells by a decrease in production and by an excessive pressure build up in injection wells.
Recently, Haoud Berkaoui field suffers mainly from formation damage related to drilling mud. Laboratory test results show permeability improvement for 3 systems.
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.

Proceedings of an international conference Subsea Controls and Data Acquisition ‘ 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. Visual observations of cores using SEM are also used as interpretation tools.
Besides, optimum volume is predicted based on the laboratory acid response curves. Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in the direction to Ouargla city. Geophysical Research Abstracts Vol. Publishers Content Coverage Privacy. Rules of thumb may not be convenient and always over estimate or underestimate the volume. Acidizing tests of 4 different acids are conducted and discussed to select the optimum fluids.
Abstract The most common reason of formation damage is the drilling operations.
