Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Due to the growing share of hard-to-recover oil reserves, the task of their development becomes more urgent. The development of reservoirs with a complex geological structure is caused by low rates of sampling and values of the oil recovery coefficient. This article discusses the effectiveness of the application of horizontal well drilling technology at field X in order to increase the efficiency of development and coverage of oil deposits. A horizontal well was successfully drilled at the X field, the trunk of which reaches up to 1,000 m. For all the time, 4 horizontal wells have been drilled at the field, with the exception of the one already mentioned, the length of the trunks of other wells vary from 300 to 358 m.
