NON-MAGNETIC OPENHOLE WHIPSTOCK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18112633 titled 'NON-MAGNETIC OPENHOLE WHIPSTOCK

The abstract describes a patent application for a bottomhole assembly (BHA) consisting of an orientation sub and a non-magnetic whipstock. The orientation sub is designed to orient tools in a wellbore, while the non-magnetic whipstock diverts the drill bit to create a secondary wellbore in the subterranean formation.

  • The BHA includes an orientation sub and a non-magnetic whipstock.
  • The orientation sub can receive a gyroscopic orientation tool or act as a measurement-while-drilling sub for orienting in a wellbore.
  • The non-magnetic whipstock is coupled to the orientation sub and has a ramp with a sloped surface to divert the drill bit for sidetracking.
  • The ramp has ports for cement to secure the whipstock in the wellbore before diverting the drill bit.

Potential Applications: - Oil and gas drilling operations - Wellbore sidetracking in subterranean formations

Problems Solved: - Efficiently creating secondary wellbores - Securing whipstock in the wellbore

Benefits: - Improved drilling accuracy - Enhanced wellbore construction

Commercial Applications: Title: Innovative Bottomhole Assembly for Enhanced Wellbore Construction This technology can be used in oil and gas exploration and production to optimize drilling operations and create secondary wellbores efficiently.

Questions about the technology: 1. How does the non-magnetic whipstock improve drilling operations? - The non-magnetic whipstock diverts the drill bit to create secondary wellbores, enhancing drilling efficiency. 2. What are the key benefits of using the orientation sub in the BHA? - The orientation sub allows for precise tool orientation in the wellbore, improving drilling accuracy.


Original Abstract Submitted

A bottomhole assembly (BHA) includes an orientation sub and a non-magnetic whipstock. The orientation sub is configured to receive a gyroscopic orientation tool or is a measurement-while-drilling sub for orienting the orientation sub in a wellbore formed in a subterranean formation. The non-magnetic whipstock is coupled to the orientation sub. The non-magnetic whipstock includes a ramp with a sloped surface that is configured to divert a direction of a drill bit that has drilled through the orientation sub for sidetracking from the wellbore and forming a secondary wellbore in the subterranean formation. The ramp defines a set of ports that are configured to allow cement to permeate throughout the ramp for securing the non-magnetic whipstock in the wellbore before diverting the direction of the drill bit.
