Well records of the Oil Gas and Salt Resources Library (OGSRL) are maintained in the Ontario Petroleum Data System (OPDS) and are the principal source of data on the subsurface geology of southern Ontario. In this project significant improvements have been made to data quality in OPDS through a process of capture and compilation of existing data, QA/QC edits to the existing data, and creation and addition of new data. Edits were completed to 30,320 formation top picks in 7,812 wells. These improvements were completed as part of the development of a 3-D lithostratigraphic model of the Paleozoic bedrock of southern Ontario. The completion of this QA/QC at the OGSRL has the permanent benefit that any future users of the library data will have access to these corrections. OPDS data supports resource industries involved in exploration for and development of salt, oil, natural gas, groundwater, compressed air energy storage, disposal of oil field fluids, geological storage of hydrocarbons, and permanent geological storage of nuclear wastes. It also supports public education and the training of new geoscientists and geological engineers. The southern Ontario 3-D model is data-driven. OPDS is the key source of data for the model and illustrates the value of a properly constructed and actively maintained wells database. Without OPDS the 3-D modelling project would not have been possible.
