Our objective is to map tripolitic high porosity chert sweet spots within a highly fractured Mississippian lime reservoir, located in Osage County, Oklahoma, which also contains tight nonporous chert using impedance inversion correlated with surface seismic attributes and well log information in the survey.
30 cze 2021 · The tripolite may be due to hydrothermal fluids that occurred during the Ouachita Orogeny, classified as tripolitic chert (McGilvery et al., 2016). Cains (2019) reports that the tripolite is not found along bedding planes.
1 sty 2001 · Tripolitic chert is a diagenetically altered form of cherts which show high porosity and low resistivity.
Instead of defining the facies stratigraphically, we need to define them either diagenetically (tight limestone, stratified limestone and nonporous chert, and highly porous tripolitic chert) or structurally (fractured versus unfractured chert and limestone).
7 gru 1990 · Definition of tripolite. • (a) a light-colored porous friable siliceous (largely chalcedonic) sedimentary rock, which occurs in powdery or earthy masses that result from the weathering of chert or siliceous limestone (Tarr, 1938, P. 27). It has a harsh rough feel and is used for the polishing of metals and stones.
1 sty 2019 · The main reservoir rock, tripolitic chert, primarily formed by in situ karst development of subaerial highs (e.g., sponge bioherms and cherty limestone) followed by silica replacement of calcite and partial to complete dissolution of the remaining calcite to form secondary porosity.
