Directional Drilling Technologies

XR Team innovates and develops downhole drilling technologies through its XR Lateral company. Our primary purpose is to assist E&P Companies to better drill directional and horizontal wells with emphasis on shale plays. The company focuses on drilling efficiency and placement accuracy in the build and lateral sections of horizontal wells by introducing new technologies into the steerable motor BHA.

Our technologies reduce drilling cost, extend lateral reach, and provide wellbore quality that enhances hydrocarbon production.

Traditional directional drilling practice has too often accepted OverBend™ high bend angle BHAs that impart excessive vibration, dogleg severity, and borehole degradation.

Our core technology provides predictable, as planned build rates using unprecedented MicroBend™ low bend angle BHAs. This technology sets up to provide smoother transitions, better tool-face control, more efficient use of power, and improved hole cleaning, resulting in higher ROP, longer tool life, and smoother wellbores.

XR Lateral is actively developing drilling solutions with three IP protected innovations:

· Compound Geometric Guidance (CGG)

· Dynamic Lateral Pad (DLP)

· Laterally Oriented Cutting Structure (LOCS).

OUT OF CUT DRILLING DISFUNCTION

Through extensive modeling XR Team identified OCDD as the primary contributor to bit damage in rotate mode with a bent housing motor. As the assembly is rotated the some of the cutters of the drill bit cyclically exit and reenter the rock, causing recurrent impact damage to the cutting structure. In an effort to address this problem bit designers have increasingly “hardened” drill bits with depth of cut limiters, impact limiters, and back up cutting structure, all of which reduce the efficiency of the drill bit.

None of these corrective measures address the root cause which is the bend angle of the assembly driving OCDD. Higher bend angles increase the incidence of OCDD damage.

Eccentric Rotation of Drilling Mud Motor Including XR Team's CGG Technology

CGG (Compound Geometric Guidance) enables a 1.5° bend angle drilling motor capable of drilling 12°+/100' curve sections and drilling a near-gage hole while rotating. The CGP's (Compound Geometric Positioners) optimally position the motor in the hole for maximum bend efficiency. The major drilling benefit is an increase in rotary RPM while rotating and the potential to directionally drill while rotating due to a closer to gage hole and controlling rotate tendency with parameters and contact points.

Eccentric Motion of a Conventional 2.25˚Fixed Bend Drilling Motor

Conventional motor with a 2.25° bend angle drilling motor capable of drilling 12°+/100' curve sections but drilling an excessively large, over-gage while rotating. The eccentric motion demonstrates Out of Cut Drilling Dysfunction (OCDD) which can lead to premature bit failure and other BHA component failure.

XR Team's DiaGlide + CGG (Compound Geometric Guidance) Technology

DiaGlide + CGG enables a 1° bend angle drilling motor capable of drilling

12°+/100' curve sections and drilling a near-gage hole while rotating. The use of DiaGlide bearings allows for a reduction in Bit-to-Bend and thus bend angle combined with the bend angle reduction from deploying CGG technology results in an ultra low bend angle of 1°. The major drilling benefit is no limitation on rotary RPM while rotating and the potential to directionally drill while rotating due to a near-gage hole and controlling rotate tendency with parameters and contact points.

Benefits to Operator

Construct quality cost effective wellbores with low NPT that do not negatively affect the production capability and/or increase completion and production lifting costs are a major challenge for Shale Operators.

XR Team studied this issue and realized drilling dysfunction caused by high bend angle mud motors is the major contributor to poor wellbore quality. This discovery drove our innovation path, leading to technologies that reduce the bend angle by as much as 50% over industry norms.
