Risk assessment for Class-VI CO2 Sequestration (C6-Well) wells require a well catalog of Oil and Gas wells within a buffer surrounding the C6-Well. Initial data downloaded from the Wyoming Oil and Gas Conservation Commission (WOGCC) can have inconsistencies such as incorrect locations or statuses. The only ways to identify and resolve the discrepancies are to field check every well in the buffer of the C6-Well. A geodatabase for the WOGCC wells is created using relationships, attachments, and domains. The data is then checked out for field use using ArcPad. A photo of the well and an updated location/status is recorded and uploaded back to the geodatabase. Data is analysis using ArcToolbox Points to Lines script show displacement of WOGCC locations to the field-checked locations. On average, 23% of the wells are mislocated. These results indicate that any future projects will require field verification.
