Horizontal wells, GIS, Wattenberg Field, Weld County, Colorado, Colorado Oil and Gas Conservation Commission’s spacing unit regulations


Horizontal wells are the most commonly drilled wells in the Wattenberg Field, located in Weld County, Colorado. Petroleum engineers have become interested in determining how many horizontal wells can economically be drilled per section in this vertically, well-developed field. Using the Colorado Oil and Gas Conservation Commission’s spacing unit regulations as a guide, a GIS workflow was developed to create the deliverables required for further analysis. Spacing units were created by applying a buffer to horizontal well surveys, and using this buffer to select intersecting quarter-quarter sections. The selected quarter-quarter sections were simplified using the dissolve tool and then spatially joined to producing wells. The resulting tabular data is exported, edited, and formatted for delivery to engineers for subsequent analysis.
