Downhole tooling refers to the tools used downhole during drilling operations. It includes drill bits, air hammer systems, mud mixers, transmitter housings, adapters, and reamers. Downhole tooling is very important in a drilling operation as it can impact the overall productivity of the machine.
Since tooling is prone to wear and tear the cost of tooling should be taken into account while considering the overall cost of operation.
Downhole tooling is selected based on the production goals of a project, geology, obstacles and ground conditions. Right tooling selection is governed by selecting the right drill bits, selecting the right sonde housing, and the correct back reaming accessories. Good downhole tooling can also help manage drilling fluid better. Since downhole tooling is an attachment, there is a possibility of losing the tools downhole.
Tooling should be sturdy, well-fitting and optimized for the drilling operation. A tool that breaks downhole can end up increasing wait time and thereby cost of the operation.
