Today, one of the most modern and successful geosteering methods in terms of net to gross value (NTG) is a proactive geosteering.

The purpose of this article is to share the experience of using Remote Boundary Detection Tools to solve various geological problems and describe the ways of using the data from it.

The method provides the ability to detect the approaching boundary (usually reservoir top) with resistivity contrast before entering it with the bit or BHA sensors. It allows to adjust well trajectory proactively and, therefore, increase Net to gross ratio.

The article shows the ways to implement global experience in horizontal wells drilling and proposes ways to reduce the cost of well construction without elimination of High-Tech equipment in BHA.

The article explains the methods of interpreting the output data from the tool that can determine the approach to one or several boundaries with resistivity contrast.
