WHAT IS WELL-LOG SEQUENCE STRATIGRAPHY?
  • Well-log Sequence Stratigraphic analysis is a methodology that permits a geologist and geophysicist to subdivide a stratigraphic section into a series of time related 3rd Order Depositional Sequences and Systems Tracts.
  • This is accomplished by using marker species, their numerical age, superpositional relationships, paleowater depth, their association with well developed shale sections, high gamma and low resistivity, well-log signatures. Seismic reflection profiles were NOT used to calibrate the placement of Sequence Boundaries and Maximum Flooding Surfaces on the well-log.
  • Subsequently, wells with Well-log Sequence Stratigraphic analysis can be correlated by MICRO-STRAT INC. to 2-D and 3-D seismic.
APPLICATIONS OF WELL-LOG SEQUENCE STRATIGRAPHY
  • Drs. Peter R. Vail and Walter W. Wornardt completed the Well-Log Sequence Stratigraphy.
  • Establish reference wells with Sequence Boundaries, Maximum Flooding Surfaces that can be age-dated (Ma) and correlated with the Global Cycle Chart.
  • Determin timing of faults, unconformities, canyon development, salt intrusion, reef development, migration, maturation and seals for hydrocarbons.
  • Graphic correlation plots; help recognize the sequence boundaries and maximum flooding surfaces.
  • Prediction of ages and Systems Tract surfaces ahead of the drill bit.

 
WELL-LOG SEQUENCE STRATIGRAPHY WILL HELP YOU TO:
  • Identify the 3rd Order Depositional Sequences and Systems Tracts that are associated with the potential hydrocarbon reservoirs, source rocks and seals.
  • Determine the play concepts for the reservoir section, coastal belt sands, shingled turbidites sands, sheet sands, and channel overbank sands (parallel to strike): incised valley fill sands and slope fan channel sands, (perpendicular to strike) and basin floor fan sands that form pancake shaped reservoir.
  • Predict the geometry, continuity and distribution of the reservoir sands both vertically and laterally.
