Title: Expanding the Limit of Economical Formation Evaluation in a Mature Gulf of Mexico Field Using Formation Evaluation While Drilling (FEWD) Technology
Abstract: In the past, traditional formation evaluation and hydrocarbon reserve appraisal have relied on petrophysical measurements made with wireline-conveyed logging tools. With the development and demonstration of the technical viability of drill collar-based resistivity and nuclear porosity sensors, formation-evaluation-while-drilling (FEWD) now offers an alternative to wireline-based evaluation. A formation evaluation strategy utilizing FEWD technology can offer economic and technical advantages over traditional wireline formation evaluation. In this paper, we explore the potential to replace wireline petrophysical data with FEWD data in a high rate of penetration (ROP), synthetic oil-based drilling fluid environment in a mature Gulf of Mexico field. Based on this work we find that FEWD offers an economically attractive and technically viable alternative to wireline tool-based formation evaluation. For the example considered, FEWD cost savings were estimated to be 16% versus wireline, and increased with the probability of pipe-conveyed wireline logging. The FEWD data compares well with comparable measurements made with wireline tools. In addition to the cost savings, FEWD data may yield a more robust interpretation than wireline-based measurements, because of temporal and spatial changes in the wellbore environment. We believe the results described here are applicable to drilling in other mature Gulf of Mexico fields.
