Use of Dipmeter as an Aid in Integrating Subsurface, Structural, and Depositional Features: Abstract
Recently developed methods of dipmeter interpretation, utilizing patterns of formation bedding plane dips, define both structural and stratigraphic dips. By using these methods, structural dips of less of less than 1° can be recognized.
Faults may be recognized and defined, both as to direction of dip and strike. Characteristic dip patterns identify bars and channels and define both the strike and direction of shale out of such sand bodies.
Unconformities and disconformities normally exhibit characteristic weathering patterns which makes them readily identifiable. Foreset beds are also readily identified by characteristic dip patterns.
Reef structures can be located and defined by interpretation of the dip patterns found in the overlying beds.
Dipmeter results are currently being used as additional evidence for the confirmation of the presence of shale diapirs.
Confirmation of the subsurface interpretations applied to dipmeter data is supplied by a multitude of outcrop studies from the Rocky Mountain, West Texas and Gulf Coast Provinces.
