Computer Processing of Log Data Improves Production In Chaveroo Field

Abstract: Computer log analysis has proved quite successful in the Chaveroo field of Roosevelt County, N.M., in a carbonate section of low permeabilities, low porosities and variable water saturations. Production in this field occurs at about 4,300 ft in the San Andres formation, a Permian carbonate with a mixture of dolomite, anhydrite and gypsum, and lesser amounts of silica, limestone and silt. Sonic, density and neutron logs, all of which respond differently to porosity and lithology, enable a mathematical solution … Show more

“…The basic theory for the modeling of compositional components from logging data was developed by Savre (1963), and further improved by Burke et al (1967) and by Dawnson-Grove and Palmer (1968). In this model, the log response for any zone is related to the sum of the proportions of the mineralogical/porosity components, each multiplied by the appropriate response coefficients of the different logging instruments.…”

“…Each log provides a single equation. This matrix formulation is a linear model introduced by Savre (1963) and further developed by Burke et al (1967). More extensive details on this methodology are given by Doveton (1994).…”

“…Such crossplots (Fig. 1) provide shaliness definition, evaporite determination (anhydrite, halite, and polyhalite; gypsum in clean, nongas-bearing zones), poor porosity resolution, and definition of Psh, ilt sh' and M sh ' Light hydrocarbons, gas, and gypsum shift the points toward the northwest; shales and compaction effects shift the points toward the east; secondary porosity shifts the trend toward the west; and borehole rugosity and washouts shift the trend toward the north.…”
