Assisted Geosteering Through Advanced Computed Algorithms

Geosteering improves the success rate by placing the borehole in the optimum position within the reservoir. It relies on the timely access to accurate decision-making information related to wellbore trajectory. With advent of unconventional resources and widespread horizontal well drilling, geosteering technologies and methods have developed substantially. The changes were mainly driven by industry challenges such as cost-cutting initiatives, performance improvement, narrower target zones and longer lateral lengths. Over the last few years, there has been a general trend to simplify bottomhole assembly (BHA) and specifically MWD/LWD tool strings. Concurrently, many operators are enforcing more rigorous requirements for the drilling target window and percentage drilled in the zone.

The purpose of this study is to evaluate the Assisted Geosteering (AG) technology and the upside it provides to Operations Geoscientist executing real-time in the complex and data-rich environment of well drilling operations.
