Abstract
A method can include receiving data for a geologic environment where the data include data acquired via different types of borehole tool sensors; based at least in part on the data, determining rock composition of the geologic environment where the rock composition includes depositional components and diagenetic components; and, based at least in part on the rock composition, outputting a stratigraphic model of at least a portion of the geologic environment.
Claims20
A method comprising:
- receiving data for a geologic environment wherein the data comprise data acquired via different types of borehole tool sensors;
- based at least in part on the data, determining rock composition of the geologic environment wherein the rock composition comprises depositional components and diagenetic components, wherein the determining rock composition comprises determining detrital mineral composition values for trace minerals associated with at least one of the depositional components and calculating a detrital index value based at least in part on the detrital mineral composition values for the trace minerals;
- and
- based at least in part on the rock composition, outputting a stratigraphic model of at least a portion of the geologic environment, wherein a portion of the stratigraphic model is attributed to a particular geological source based at least in part on the detrital index value.
A system comprising:
- a processor;
- memory accessibly by the processor;
- instructions stored in the memory and executable by the processor to instruct the system to:
- receive data for a geologic environment wherein the data comprise data acquired via different types of borehole tool sensors;
- based at least in part on the data, determine rock composition of the geologic environment wherein the rock composition comprises depositional components and diagenetic components and wherein to determine rock composition comprises determination of detrital mineral composition values for trace minerals associated with at least one of the depositional components and calculation of a detrital index value based at least in part on the detrital mineral composition values for the trace minerals;
- and
- based at least in part on the rock composition, output a stratigraphic model of at least a portion of the geologic environment, wherein a portion of the stratigraphic model is attributed to a particular geological source based at least in part on the detrital index value.
One or more non-transitory computer-readable storage media comprising processor-executable instructions wherein the processor-executable instructions comprise instructions to instruct a computer to:
- receive data for a geologic environment wherein the data comprise data acquired via different types of borehole tool sensors;
- based at least in part on the data, determine rock composition of the geologic environment wherein the rock composition comprises depositional components and diagenetic components and wherein to determine rock composition comprises determination of detrital mineral composition values for trace minerals associated with at least one of the depositional components and calculation of a detrital index value based at least in part on the detrital mineral composition values for the trace minerals;
- and
- based at least in part on the rock composition, output a stratigraphic model of at least a portion of the geologic environment, wherein a portion of the stratigraphic model is attributed to a particular geological source based at least in part on the detrital index value.
