Oil, Gas & Geothermal - CalWIMS 

CalWIMS

Since the late 1800’s, about 180,000 oil, gas, and geothermal wells have been drilled in the State of California. Approximately 88,000 are still in use today and new wells are being drilled at the rate of approximately 2,200 per year. The Division oversees close to 1000 companies that operate these wells, which produce a combined daily total of 700,000 barrels oil and 900,000 Mcf of natural gas.

The Division has six district offices with its Headquarters office located in Sacramento, CA. Each district office developed separate database applications to track information on oil and gas wells, permits, field and environmental inspections, idle wells, and other day-to-day activities. Some of these applications were developed using software (e.g., Paradox 4.5 for DOS) that is now outdated and no longer supported by the manufacturer. The databases cannot be shared with modern, industry standard databases used by Headquarters and other Division stakeholders. This results in redundant data and manual intervention to convert data into industry standard formats.

In Fiscal Year 2004, the Department of Conservation received approval to develop CalWIMS (California Well Information Management System), a multi-tiered, interactive, centralized, web-based application using object oriented framework. This new system will enable the Division to capture consistent well information from all of its districts more timely and with fewer opportunities for data entry errors. The Division will be able to use that information to better facilitate its mandated reporting requirements as well as provide industry and the general public better access to well information.
