Evolution of Well Placement Methods Introduced on the Field of Volga-Ural Oil and Gas Province

Abstract

Vast experience has been gathered in drilling horizontal wells in the Volga-Ural oil and gas province in both carbonate and clastic rocks. In order to overcome the risks, related to geological uncertainties, and achieve the wells’ objectives, almost all available logging-while-drilling technologies, related to geosteering, have been utilized. Three representative wells have been reviewed to demonstrate the advantages and drawbacks of the three geosteering methods.
