Abstract

King Field is located in the Deepwater Gulf of Mexico (GOM) about 110 miles SE of Venice, Louisiana in Mississippi Canyon blocks 84, 85, 128, and 129 (Fig. 1). The main sand, the Upper Miocene 70 (UM 70), is an under saturated oil reservoir. The sands were deposited by gravity flow processes within an intraslope basin. The formation is highly porous and permeable (31%, 1000md). Lateral and vertical heterogeneities identified by seismic amplitudes and Amplitude Versus Offset attribute analyses have been confirmed by, and calibrated to, well logs, cores and flow tests. Sedimentary facies studies have shown that at least two different styles of deposition are present; lower massive sheet sand, and an upper sand which is more variable and probably channelized. The trap is a three-way antiformal closure against a major fault with a hydrocarbon column of 1400 ft.

Permeability and pressure data were obtained from core, nuclear magnetic resonance (NMR) measurement, MDT Modular Formation Dynamic Tester, closed chamber, flowback and recent permanent gauge data. This paper compares and demonstrates the utilization of results from each source of measurement on different wells. Differences and agreements of these data are discussed. This work demonstrates the use of these data to define a geologic model and better predict well productivity and reservoir continuity. Lessons learned from integrating these multiple sources are summarized.
