Data Recording for Horizontal and ERD wells
Successful performance in horizontal drilling of wells requires the development of a comprehensive database of experience as optimum practice is often very area specific.
- drilling parameters used, WOB, RPM, Torque, pressures, circulation rates etc.
- motor condition, stabiliser wear patterns
- mud properties
- comparison of predicted vs. actual BHA performance
- survey data, toolface control data
- hole conditions on trips
- formation data, hydrocarbon data (gas compositions ratios etc)
- casing wear. The weight of recovered metal shavings should be . . .
