Accuracy enhancements
Corrections that shrink the ellipse.
Corrections and referencing techniques that reduce positional uncertainty and improve drilling outcomes.
The accuracy enhancements
- MFMMain Field ModelCalculate magnetic reference values and document their uncertainty for MWD survey processing.
- IFR1In-Field ReferencingEstimate local crustal magnetic contributions and their uncertainty for MWD survey references.
- IFR2Interpolation In-Field ReferencingEstimate temporal magnetic variation at the wellsite using suitable observatory data.
- SAGBHA MisalignmentEstimate directional sensor misalignment from BHA deflection and apply accepted inclination corrections.
- MSAMulti-Station AnalysisEstimate systematic directional sensor corrections during drilling when suitable survey data is available.
- HFSHigh Frequency SurveyingUse suitable high-density directional measurements to improve estimates of the path between conventional survey stations.
- BYSIn developmentBHA Yield SurveyingIn development: estimates of BHA build and turn tendencies under stated conditions.
