GEOLOGICAL ASSESSMENT OF YELSK (POZNYAKEVICH) OIL DEPOSIT IN THE PRIPYAT TROUGH
The article analyzes the results of exploration works on the first oil show in Belarus in 1953 in the well Yelskaya 2. Receiving the inflow of oil at a stage of regional research of the Pripyat trough was a positive factor for further continuation of oil search works. The performed works on test of the productive intra salt horizon in an operational column with the subsequent production test of the well confirms the production significance of the revealed oil deposit. For a long time, study and development of the Yelsk oil deposit was restrained by further discoveries of large main oil fields in Belarus, as well as quality of oil with regard to its density and content of sulfur and hydrogen sulfide. Currently, during development of nonconventional hydrocarbonic raw materials, this object is worthy of further assessment and development. The results in the Yelskaya area in the course of the drilling and production test of Well 2, as well as the study of work of the well in various modes have been analyzed. The well works with steady flowing with chokes 3 and 4 mm in diameter and an output of 15-18 m3/d. Oil reserves in the deposits have been determined to make up156.2 thousand tons. Prospects of works on further research, assessment and development of the deposit have been determined.
