Abstract
A head assembly for a drilling operation. The assembly includes a retractor case comprising a retractor pin slot. The assembly includes a body that comprises a body pin slot, wherein an interior space of the body is configured to receive the retractor case. The assembly includes a latch ear coupled to the body, wherein at least a portion of the latch ear extends outward relative to the body. The assembly includes an expansion block at least partially disposed within an interior space defined by the retractor case. The assembly is such that a position of the expansion block along a longitudinal axis of the assembly determines whether the latch ear is in an extended position or a retracted position relative to the body sidewall.
Claims17
An assembly for performing a drilling operation in a substrate, the assembly comprising:
- a tube cap piston comprising a threaded recess;
- a viscosity adjustment screw coupled to the tube cap piston, wherein a threaded portion of the viscosity adjustment screw is screwed into the threaded recess of the tube cap piston;
- and
- a tube cap comprising a tube cap sidewall, wherein the tube cap further comprises a tube cap port disposed within the tube cap sidewall;
- wherein the tube cap piston and the viscosity adjustment screw are disposed within a hollow interior space defined by the tube cap sidewall;
- wherein a fluid passageway is formed in between the tube cap port and an exterior surface of the tube cap piston;
- and
- wherein the threaded portion of the viscosity adjustment screw is threaded into or out of the threaded recess of the tube cap piston to adjust a size of the fluid passageway;
- wherein the assembly comprises an uphole end and a downhole end;
- and
- wherein the viscosity adjustment screw is located uphole relative to the tube cap piston.
