Authors: Gasumov R. A. , Vagina T. Sh. , Kostukov S. V.
Published: November 2018

In modern conditions the complexity of conducting the repair work of wells has been steadily increasing. This is due to a significant deterioration of mining and geological conditions of oilfields - decrease of reservoir pressure, deterioration of reservoir properties of productive formations, the infiltration of the formation water, and others. Also, there are still relevant problems associated with conducting the works on wells in terrigenous reservoirs with heterogonous permeability containing clay minerals. In such conditions on the first place arises the question of preservation of reservoir properties of formations during the repair works.

Published: November 2018

Rift trough of Central Africa have been studied in detail since the early 1980s and during this time, signifi-cant hydrocarbon reserves were discovered within these structures. The most promising is the Mujlad basin, within which the thickness of the sedimentary cover can reach 13,5 km. Analysis of the core material made it possible not only to isolate facies complexes and sedimentation environments, but also to link them spatially. Usage of sequence stratigraphy methods made it possible to qualitatively dissociate the sufficiently massive deposits of the Abu Gabra formation into synchronous intervals and determine the most promising areas of hydrocarbons accumulation.

Published: November 2018

Secondary opening of productive oil and gas reservoirs by using cumulative and bullet perfo-ration methods in directional wells with high values of inclination angles (40-60º) requires a solution of technological problems caused by the justification of the interval of their implementation. This is especially important for multi-layered reservoirs with alternating water saturated and oil saturated horizons and the absence of an insulating low-permeability screen, for example, a clay layer (tire). The article makes an attempt to attract geological services, owners of companies that develop deposits with such conditions, in order to increase the requirements for the appointment of a perforation interval. The authors give some proposals based on the actual results of well con-struction.

The depth of penetration of the binding fluid into the formation is one of the factors to determine the effectiveness of semiconsolidated reservoir stabilization by a chemical method. This value depends on the properties of the productive formation, the component composition and rheological characteristics of the binding fluid, as well as the technological parameters of its injection into the unconsolidated reservoir. The article presents the results of the interrelation of the above factors on the value of fluid penetration radius, the optimum rheological characteristics and the parameters of the binding fluid injection are established.
