Pluspetrol Saves 5.5 Drilling Days and 7.5 Total Days Using NeoSteer CL ABSS, La Calera Field, Argentina

In the Vaca Muerta Basin, Pluspetrol used the NeoSteer CL curve and lateral at-bit steerable system (ABSS) to drill over 2,600 m in less than 83 h, maintaining hole quality and remaining in the zone during the lateral section—and all in a single run.

A new category in steering technology

This technology is the first of its kind and represents a new category bridging cutting structure and steerable technology.

At-bit steerable systems (ABSSs) are capable of drilling both high-dogleg severity (DLS) curve sections and straighter, higher-quality lateral sections at high performance without the need to change the configuration between sections. This saves significant time and tool cost associated with tripping out and changing the BHA.

Both the NeoSteer CL curve and lateral and the NeoSteer CLx extreme curve and lateral at-bit steerable systems are compatible with Blade Family cutting structures from Smith Bits, a Schlumberger company. These cutting elements have extraordinary durability in all kinds of environments and enable the NeoSteer CL and CLx ABSSs to drill farther, faster, more responsively, and in a single run. Additionally, both ABSSs have increased actuator pressure drop range, hold inclination and azimuth (HIA), and dual downlinking capabilities. Onboard near-bit sensors take continuous six-axis inclination and azimuth measurements with a 6-ft range, and optional natural gamma ray and azimuthal images with a 9-ft range.
