Background

JV Kazgermunai, LLP planned to drill a horizontal section to access a thin reservoir. However, there was uncertainty as to the exact position of the reservoir layers within the formation and their lateral continuity. Consequently, the company needed to ascertain better positioning of the target reservoirs, confirm the lateral extent of these intervals, and place the maximum length of the lateral inside the reservoir layer(s) while minimizing the risk of exiting the reservoir bottom.

Single Run with PowerDrive X6 RSS and PeriScope HD Service Places Lateral in Thin Kazakhstan Reservoir

Bed boundary and RSS geosteering services thread treacherous interval measuring as thin as 0.5 m, onshore

PeriScope HD service identified the layer thicknesses, ranging from about 0.5 m to 1.7 m, while also determining their lateral extent and helping to understand structural behavior. Despite the low resistivity contrast between layers and the surrounding formation, two possible faults were uncovered. Combined with the push-the-bit steering capability of the PowerDrive X6 RSS, the data enabled the operator to sustain navigation within the target interval.
