2-step log analysis of the Spellacy reservoir in the giant Midway-Sunset Field, Kern County, California



2-step log analysis of the Spellacy reservoir in the giant Midway-Sunset Field, Kern County, California



Annual Meeting Abstracts - American Association of Petroleum Geologists and Society of Economic Paleontologists and Mineralogists 5: 135



A technique is presented for simple, effective log analysis of (Miocene) "Spellacy" sands and conglomerates of the Santa Margarita Formation at Midway-Sunset Field in Kern County, California. Results are shown graphically on the log display and are quantified for mapping. Requirements are digital wireline data--in this simple case, just resistivity and porosities--and flexible log analysis software such as QLA2 (super TM) . The first step of this technique discriminates between reservoir-quality and non-reservoir-quality intervals yielding three color-coded categories. A narrow color-filled column is added to the well log display to graphically communicate the vertical distribution of reservoir-quality and barrier intervals. The second step performs a fluid analysis on the reservoir-quality category (intervals) yielding three more color-coded categories. The results of the fluid analysis are graphically displayed in a second narrow color-filled column on the well log. Analysis results are captured from a tabular report for mapping. Quantifiable products include 1) thicknesses: original net pay, current net pay, reservoir quality, total sand, total porosity, phi-H, etc.; 2) averages: original net pay porosity; current net pay porosity, current net pay saturation, current net pay bulk volume oil, etc.; and 3) ratios: thickness of reservoir quality to total sand and thickness of current net pay to total interval.
