The major goal of oil and gas companies working in the oilfields on late stages development is to maintain a high level hydrocarbon production. Analysis well intervention techniques (WITs) Samara Region shows that most often bottomhole area treated with reagents containing hydrochloric acid, which significantly effects efficiency fluid preparation processes. paper summarizes results studies imp...

Well killing is an important technological stage before conducting workover operation, one of the tasks which to preserve and restore natural filtration characteristics bottomhole formation zone (BFZ). Special attention should be paid choice well technologies development wells in complicated conditions, include abnormally low reservoir pressure, high oil-gas ratio carbonate type. To productive ...

There should be factual information on the skin-effect each well that reduces oil and gas production for operational work, as calculation of deposits or design field development. Well development operation experience shows contamination bottomhole zone deterioration leakage properties may associated not only with collution, but also events such obliteration rock compaction. Thus, during wells, ...

This article is the result of studies rheological properties and reactivity acid solutions technical lignosulfonate, decationized lignosulfonic acid, hydrochloric with addition lignosulfonate. Compositions that include lignosulfonate can be used as displacement agents in development watered layers inhomogeneous reservoir properties. The use thickening additives solves several problems. Slowing ...

Abstract Specialists of Dnipro University Technology are among the leading researchers involved in studying specifics implementation and functioning rational energy-efficient schemes organization circulation processes while well drilling operating. In particular, we have carried out thorough comprehensive studies physicochemical phenomena used creating, preparing, using washing fluids. The purp...

The Alberta No. 1 project is a planned power and heat (direct use) geothermal located within the County of Grande Prairie Municipal District Greenview. For to successfully produce on commercial scale, temperatures 120 °C are desirable. produced fluids must also be from highly permeable formations depths less than 4500 m. Bottomhole temperature measurements wireline logs Alberta’s extensive oil ...
