Dipmeter Surveys (Reef Interpretation )
Reef Interpretation IntroductionBuried topography may significantly influence the thickness, sedimentation, and dip attitude of beds overlying topographic features. One of the first stratigraphic applications of dipmeter data was to determine the positions of wells drilled on buried topographic features. The factor contributing to the interpretation of these situations is the drape of beds over the underlying buried topography....
Dipmeter Surveys (Fault Interpretation)
Fault Interpretation IntroductionFaulting occurs when beds are in tension or under compression. Such forces produce normal faults and reverse or thrust faults. In areas that have undergone mainly tension (such as the northern Gulf of Mexico), almost all of the faulting is normal. In areas that have undergone both earlier tension and later compression, both normal and reverse/thrust faults may be present in the same well. For dipmeter...
Dipmeter Surveys (Structural Dip Interpretation )
Structural Dip Interpretation Structural Dip InterpretationStructural dip changes (and the lack of such changes) are good indicators of the type of structure present ( Figure 1 ). The following are guidelines for interpreting structure based on structural dip changes.Structural dip decreases upward in structures uplifted contemporaneously with deposition. Constant dip over an interval indicates postdepositional structural...
Dipmeter Surveys (Dip Patterns)
Dip PatternsBasic TypesIntroductionThere are several graphical methods of plotting dip computations. This chapter covers interpretation rules based on the common "tadpole" plot. The head of the tadpole indicates dip magnitude and is plotted on a dip scale ranging from 0° to 90° versus depth. The tail of the tadpole, which points in the downdip direction, is plotted on a compass rose (north, up; east to the right; south, down;...
