A method for selecting potential well locations in a reservoir, which comprises:
- a) selecting a bounding box with grid-block dimensions;
- b) selecting a surface grid-block for a potential well location in a reservoir grid model comprising multiple grid-blocks;
- c) positioning the bounding box around the surface grid-block;
- d) calculating a total original gas-in-place in the bounding box using an original gas-in-place for each grid-block in the bounding box;
- e) repeating steps b)-d) for each surface grid-block in the reservoir grid model using a computer processor;
- and
- f) selecting a largest total original gas-in-place calculated for a bounding box, which represents a bounding box with surface grid-block coordinates for a best well location.
A non-transitory program carrier device tangibly carrying computer-executable instructions for selecting potential well locations in a reservoir, the instructions being executable to implement:
- a) selecting a bounding box with grid-block dimensions;
- b) selecting a surface grid-block for a potential well location in a reservoir grid model comprising multiple grid-blocks;
- c) positioning the bounding box around the surface grid-block;

- e) repeating steps b)-d) for each surface grid-block in the reservoir grid model;
- and
- f) selecting a largest total original gas-in-place calculated for a bounding box, which represents a bounding box with surface grid-block coordinates for a best well location.
