Transforming Oil Wells into Batteries for the Sun and Wind
February 2, 2021USC
What happens when oil and gas wells run dry? The answer: little good.
The owners, often smaller businesses that have acquired the wells from major producers at a discount when oil and gas output declines, might pay anywhere from $70,000 to $500,000 to safely cap them. The process involves filling the underground pipes with cement to seal off the oil and gas sources and then cutting the top part of the casing. However, the cost rises exponentially if engineers must clean up and remediate contaminated soil.
Other times, producers simply walk away. In California alone, there are some 5,540 orphan wells and 37,000 idle wells, including several in Los Angeles County. When that happens, state agencies become responsible for taking the proper abandonment steps, costing California and other taxpayers tens of millions of dollars annually.
