An elastic model with volume decrease is established to relate the surface subsidence to the dissolution-collapse at depth.

These wells are taken as an example to compare between treatment volumes obtained from laboratory results and those obtained using the rule of thumb.

Proceedings of an International Conference Submersible Technology: They affect the reservoir as pore blocking by solids, clay swelling and dispersion and liquid block which reduces effective permeability to hydrocarbons.

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 berkaooui the new km pipeline. 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.

Our analysis shows a mean subsidence of 4 mm per year located around the OKN32 and in the direction to Ouargla city. Besides, optimum volume is predicted based on the laboratory acid response curves.

Many techniques are developed to overcome formation damage and to restore or ameliorate wells productivity.

ABB will also supply a complete LPG pumping station including all the electrical, piping and mechanical equipment. Skip to main content.

Formation damage can occur during the drilling or coring operations, well completion, workover and production. Damage diagnostic shows verkaoui that corrosion products caused by anaerobic bacteria affect the injectivity of injection wells.

Help Center Find new research papers in: The determination of acid volume is complicated and is generally based on field experience or using rules of thumb. Selection methods berkoui on laboratory experiments, however, are more close to real estimates since they take into consideration the rock mineralogy.

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 hapud in the same area. Introduction In the life of a well, its productivity or injectivity is affected by formation damage which is an undesirable technical and economic problem. Log in to your subscription Username.

One of those method is “Matrix haodu which consists of injecting acids into the formation below fracturing pressure to eliminate the damage around the well.

Recently, Haoud Berkaoui field suffers mainly from formation damage related to drilling mud. Mud filtrate and fines invasion during drilling are the most important problems that affect petroleum reservoirs. Damage is detected in production wells by a decrease in production and by an excessive pressure build up in injection wells.
