The NeoSteer CLx extreme curve and lateral at-bit steerable system (ABSS) is specifically designed to enable drilling the curve and lateral in a single run. It lets you achieve high build rates and extend lateral lengths in unconventional drilling applications. Especially where vertical, curve, and lateral sections are the same hole size, the NeoSteer CLx ABSS reduces NPT by eliminating the need to change out the BHA for every section.
The NeoSteer CLx ABSS uses an actuating system to push against the borehole wall for propulsion; the pistons are fully integrated with the cutting structure for greater curvature leverage. The NeoSteer CLx ABSS uses this leverage to achieve higher build rates with no additional application of hydraulic force. This provides the ability to meet both the build requirements in the curve section and the directional control requirements in the lateral section.
The NeoSteer CLx ABSS incorporates metal-to-metal hydraulic seals that reduce erosion and increase hydraulic design capability for improved performance. In addition, the steering technology can be equipped with XPC extreme-profile single shoulder connections to increase reliability during high-dogleg severity drilling. These connectors also enable compatibility with Smith Bits PDC Blade Family bits equipped with the proper unique cutting elements for formation-specific challenges. The cutting structure and steering technology of the NeoSteer CLx ABSS work in concert to provide single-run drilling with greater drilling efficiency.
The NeoSteer CLx ABSS includes comprehensive six-axis continuous inclination and azimuth measurements. The multiaxial component enables automatic hold inclination and azimuth (HIA) measurements for precise well positioning. This feature, along with self-steering capabilities, helps provide smooth tangents with minimized tortuosity. Near-bit extended-range gamma ray measurements provide additional well positioning data for improved real-time decision making.
The NeoSteer CLx ABSS can be configured with an onboard azimuthal image gamma ray cartridge to improve in-zone percentage and enable steering within the reservoir sweet spot. With an azimuthal gamma ray cartridge just 6 ft behind the cutting structure, the ABSS can identify signs of changing lithology earlier to enact instant steering corrections.
