Abstract
Distributing petrofacies using analytical modeling. At least some of the illustrative embodiments are methods including: creating, by a computer system, a geocellular model of an underground formation, the creating by: reading a first value of a first rock property associated with a first well log; associating the first value of the first rock property with a first cell of a plurality of cell of the geocellular model; assigning a value of the first rock property to each cell of the plurality of cells based on the first value and a datum of information, the datum of information distinct from the first value.
Claims23
A method comprising:
- creating, by a computer system, a geocellular model of an underground formation, the creating by:
- reading a first value of a first rock property associated with a first well log;
- associating the first value of the first rock property with a first cell of a plurality of cells of the geocellular model;
- assigning a value of the first rock property to each cell of the plurality cells based on the first value and a datum of information, the datum of information distinct from the first value.
A computer system comprising:
- a processor;
- a memory coupled to the processor;
- the memory storing a program that, when executed by the processor, causes the processor to create a geocellular model by causing the processor to:
- read a first value of a first rock property associated with a first well log;
- associate the first value of the first rock property with a first cell of a geocellular model, the geocellular model comprising a plurality of cells, and the first cell one of the plurality of cells;
- read a second value of a first rock property associated with a second well log distinct from the first well log;
- associate the second value of the first rock property with a second cell of a geocellular model, the second cell one of the plurality of cells and the second cell distinct from the first cell;
- assign a value of the first rock property to each cell of the plurality cells, the assignment to each cell based on the first value and the second value;
- and
- determining a rock type for each of the plurality of cells, the determining based on the rock properties associated with each cell.
A non-transitory computer-readable medium storing a program that, when executed by a processor, causes the processor to:
- read a first value of a first rock property associated with a first well log;
- associate the first value of the first rock property with a first cell of a geocellular model of an underground formation, the geocellular model comprising a plurality of cells, and the first cell one of the plurality of cells;
- read a second value of a first rock property associated with a second well log distinct from the first well log;
- associate the second value of the first rock property with a second cell of a geocellular model, the second cell one of the plurality of cells and the second cell distinct from the first cell;
- and
- assign a value of the first rock property to each cell of the plurality cells, the assignment to each cell based on the first value and the second value.
