Title: Impact of Diagenesis on Log Interpretation: ABSTRACT

Author(s): William R. Almon, Alvin L. Schultz

Article Type: Meeting abstract


Significant problems arise in the interpretation of wire-line logs from diagenetically altered rocks. How does one interpret a zone that on the logs appears water filled or noncommercial? Is the zone truly water filled? If the zone is water filled, does it serve as a seal for a downdip hydrocarbon accumulation?

An understanding of the degree of diagenesis and its timing will allow the wire-line logs to be interpreted in the proper manner and will prevent the abandoning of potentially productive wells and lead to the discovery of hydrocarbons held in diagenetic traps.
