Some aspects of enhancing the oil and gas fields’ further-development efficiency at late stage
A.A. MustafayevIn the article topical issues of hydrocarbon fields development efficiency increasing at late stage by regulation of formation system are considered. On the model of Palchig Pilpilasi offshore field development, the analysis of oil production current status was carried out, the characteristic features of basic technological indexes were reduced and the prospects of fields further development considering integrated approach were viewed. The field survey data on the application of physical fields (pressure fields) for Palchig Pilpilasi field non-Newtonian oils intensification are presented. It was shown, that this technology application enabled to increase well output considerably. The approaches, presented in the article meet the requirements of energy and resource saving and they are directed to oil fields development process efficiency enhancing significantly. These approaches provide for the effect on separate wells as well as on the whole reservoir. The advantage of these approaches is in their application in oil-gas fields re-development projects and also in oil fields with recoverable reserves, but are difficult to realize.
