Detailed Hydrocarbon Logs Enhance Formation Evaluation

When presented on the conventional API wireline log format, calibrated hydrocarbon well logging data can be readily integrated into the formation evaluation process. Direct indications of hydrocarbon accumulations often provide vital qualification of wireline log interpretation. Selection of test intervals and positioning of perforations can be accomplished most effectively through synergistic use of the Detailed Hydrocarbon Log and the wireline log suite. With this paper, the authors introduce a new concept of detailed hydrocarbon logging to those involved in formation evaluation work throughout the petroleum industry. Further, instructions are given to demonstrate how one can prepare such detailed logs from raw data, so that the resulting log will closely resemble in format and significance any of the conventional wireline log traces.
