BHA and bit run directional post-analysis service description
Unexpected directional behavior is a key concern when drilling. To get prepared for these situations in future drilling phases, DrillScan offers the BHA and Bit Run Directional Post-Analysis service. It consists in using our strong in-house expertise in directional drilling.
This service enables:
- Understand counter-performance observed during the run of any detailed BHA (Rotary, VGS, RSS, Motor, RWD…).
- Using complete surface and downhole data sets while drilling (caliper, UCS, WOB, Activation or TFO log).
- Allows to compare actual performance results versus models prediction.
- This comparison will provide sufficient information to understand and define what happened downhole through unknown or uncertain parameters such as friction factor, hole overgauge or bit directional behavior (bit steerability and walk angle).
BHA and Bit Run Directional Post-Analysis is an iterative process that results in a critical optimization for next BHA runs simulations accuracy. This unique process allows to improve significantly the learning curve and drilling performance in multiple wells development projects.
Diagnostic of root causes post-analysis allows to provide you suitable recommendations regarding proper PDC Bit choice, Motors or RSS settings to improve your drilling performance on future BHA runs allowing shoe-to-shoe single BHA run for given drilling section.
Benefits of BHA and bit run directional post analysis
| Pre-Well | Real Time | Post-Well |
|---|---|---|
The BHA and Bit Directional Pre-Analysis service enables to recommend BHA and bit design optimisation to reach your directional target.
The Wellbore Trajectory Prediction service allows to simulate the expected directional behavior of any BHA over a run and assess borehole tortuosity.
Directional Performance Enhancement service is based on a pragmatic approach of BHA directional analysis.
BHA and Bit Run Directional Post-Analysis service allows you to understand any unexpected BHA directional behavior in order to increase your performance for next runs.
