Statistical approach to infill-drilling studies---case history of the Ozona Canyon sands. C.L. Cipolla and M.C. Wood. SPE Reservoir Engng., August 1996, 11(3), 196--202.
The development is reported of a number of tight-gas reservoirs, initially on 320-acre well spacing, with subsequent infill drilling to 160- and 80-acre well spacing. Average well-drainage area however, is calculated from performance history to be only 36 acres. This technique presented is applicable to fields where geologic and production data indicate that wells can be individually modelled using a single-well simulator. A small number of wells are modelled to develop distributions of drainage area and ultimate gas recovery that represent the entire field. These distributions being used to identify infill-drilling opportunities. 11 refs.
