... June 25-29, 2016. ABSTRACT Complex geology in the West Delta 73 mature field, including lateral heterogeneity, along with thin oil columns, variable oil/water contacts, weak seismic resolution, and uncertainty in formation tops, makes landing and remaining in the best quality reservoir rock (sweet spot...

... important parameter in log interpre- tation since it is one of the main sources of error in the saturation exponent. This paper shows that rock nettability can be determined with wireline formation pressure measurements above, in, and below the tran- sition zone of an oil-water contact, when other logging...

... individual wells proved to be a costly production problem. This was partially solved by routine field-wide checks of the position of the oil/water contact using a through tubing chlorine logging tool. Results obtained with this tool, showed that regular monitoring of the rise in oil/water contact over...

... with elevation to a height more than 225 feet above the field-established oil/water contacts. Quantitative interpretations were made possible by an excellent combination of logs, special techniques for reading and correcting the logging curves, and special core analyses. Induction logs were found applicable...
