The NeoSteer CL 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 US land unconventional drilling applications. Especially where vertical, curve, and lateral sections are the same hole size, the NeoSteer CL ABSS reduces NPT by eliminating the need to change out the BHA for every section.
The NeoSteer CL ABSS uses an actuating system to push against the borehole wall for propulsion; the pistons are placed next to the cutting structure for greater curvature leverage. The NeoSteer CL 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 CL ABSS unit 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 NeoSteer CL ABSS and customizable bits work in concert to provide single-run drilling with greater drilling efficiency.
Six-axis continuous inclination and azimuth measurements and automatic trajectory control for accurate well placement in shale and unconventional wells
The NeoSteer CL 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.
Azimuthal image gamma ray for improved steering in the curve and lateral sections
The NeoSteer CL 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.
