What Does
Technical Hole Deviation Technology Mean?
Technical hole deviation technology describes the tools and methods used to differentiate the actual path of directional drilling from the path that was originally planned. It is a general term that describes the tools, tool settings and monitoring capabilities related to the progress of directional drilling as well as the evaluation of geosteering performance.
Trenchlesspedia Explains Technical Hole Deviation Technology
Quite a few measurements come into play in the quantification of directional control performance in horizontal directional drilling. These include vertical deviation, inclinational deviation, horizontal deviation and azimuthal deviation. Path specifications done prior to drilling are quantified in a 3D space. The defining components of technical hole deviation are based on lineal and angular differences.
A collection of common equations are attached to each component. Every turn or movement of the drill bit, whether planned or actual, is meticulously calculated. The aim is to implement real-time improvements of drill bit steering.
The plethora of defined mathematical qualities are part of a larger plan to bring automation to drilling. The fuzzy logic controller patented by Stoner Engineering in 1996 was the precursor of the technical hole deviation technology that exists today. The full automation of directional steering in the horizontal drilling business will lessen the requirement for human supervision of drilling activities.
