Knowledge of structural dip in the carbonates and evaporites overlying Keg River reefs is a valuable aid in describing reef geometry. Access to this information can be achieved through the interpretation of the continuous dipmeter log.
The route to structural dip and direction is not always straightforward, as local bedding patterns may be quite different from the over-all structural dip. With selectivity in the computing system and an understanding of the environment from which data are extracted, reliable resolution of structural dip is made possible.
Correlations between wells drilled on close spacing indicate excellent continuity on many of the very thin beds and bedding planes used for dipmeter computation. The structural dip computed from this device compares favorably with the dip calculated from correlations between wells.
The use of the dipmeter tool has enabled operators to evaluate adjoining acreage and to whipstock up-dip into production from a dry hole.
