The EUREKA software now includes a new Pipe Tortuosity, Deformation, Drift and Contact Analysis (PTDCA) Package. This module takes in high resolution directional survey data either by directly using continuous gyro data or deriving directional data (relative trajectory) from Multi-Finger Caliper data and returns the effective drift OD (Free Bore ID) through each wellbore cross-section for any given drift length larger than the directional data step increment. An inverse simulator is available that yields the maximum drift length for any given tool OD less than the "gross" bore ID. This finds application in optimum ESP placement, quantifying tool bend (angular displacement), wellbore access prediction and string/BHA optimization. We are proud to say that we are the first to come up with a Contact Analysis feature. This provides the depths at which a sucker rod would touch/rub against the walls of the surrounding tubing hence providing key information that helps prolong completion life via proactive well completion planning and rod guide placement
Well Integrity Software Development
Drift and Contact Analysis
The software provides a quick, concise and accurate means of determining the effective drift OD (Free bore ID) which is the actual maximum OD of a tool/drift that can pass through a given cross-section of the wellbore for a specific drift length, and vice versa without bending stresses; using an inverse simulator. Pipes do not necessarily have to be "deformed" to pose access problems. Our algorithm puts into consideration both the local pipe deformation and micro-doglegs/tortuosity from well trajectory.
Our signature contact analysis module determines the depths at which a sucker rod would touch/rub against the walls of the tubing (or surrounding pipe) causing wear and tear as it strokes up and down. This helps in proactively placing rod guides at the right positions to prolong the life of the completion.
