oa Geonavigation Using Petroinfotech Prosystem Software Is One of the Main Methods of Successfully Directing Directional Wells on the Shelf of the Caspian Sea

Oil and Gas Condensate Field. V. Filanovsky is located in the northern part of the water area of the Caspian Sea. The deposit is confined to the anticlinal uplift, characterized by a series of burst faults of fault type. The initial geological model of the deposit is based on the interpretation of 3D seismic data and GIS data in 3 reference wells. The accuracy of the position of the roof of the target productive horizon in the planning of the first horizontal well was estimated at +/- 20 m vertically, according to the structural constructs. Accumulated in OOO LUKOIL-Nizhnevolzhskneft drilling experience with the use of an integrated approach to the analysis of geological and geophysical information and decision making allows successful successful entry of complex horizontal wells. Implementation of these tasks requires an easy-to-use and mastering software covering all aspects of the planning of trajectories, posting and analysis of the results of horizontal drilling of trunks. An example of the use of PetroInfoTech ProSystem software with the posting of a doublebarrel horizontal well at the deposit is presented. V. Filanovsky.
