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

Abstract Horizontal drilling enables field development with less wells and smaller environmental footprint, reducing drawdown, increasing production and sweep area. Despite these advantages, horizontal drilling is not widespread in Kazakhstan, possibly due to limited information and limited knowledge of oil companies on available technologies and services that allow to manage geological risks related to horizontal drilling. The authors discuss an example showcasing geosteering with stratigraphic approach, more than one offset well and conventional non-azimuthal resistivity inversion to determine distance to boundary.
