Well Done Foundation
The Well Done Foundation (WDF) is a United States-based non-profit environmental organization that plugs abandoned oil and gas wells, preventing methane emissions from being released into the atmosphere. Established in 2019 with its headquarters in Shelby, Montana, WDF is a vendor for the carbon marketplace and sells offsets verified through the American Carbon Registry (ACR). History 

In 2019, Curtis Shuck, a former oil and gas executive of 30 years, was in Shelby, MT meeting with farmers when he discovered abandoned oil and gas wells scattered around the town's farm fields. In November 2019, Shuck initially created the Well Done Montana (WDM), LLC; a for-profit organization designed to plug wells in Montana. The organization started its pilot project in its home state and plugged its first well, known as Anderson #3, in Toole County, Montana, in April 2020. Anderson #3 stopped producing oil in the 1980s and was emitting more than 6,600 MTCO2e before it was plugged. WDM was formally reorganized into the Well Done Foundation as a non-profit 501(c)(3) organization in 2020. In June 2020, two more wells, Allen #31-8 and Blum #12, were plugged by WDF in Montana. WDF continued to expand its operations across the United States throughout 2021, amidst the COVID-19 pandemic, including Pennsylvania, New York, Ohio, West Virginia, Kansas, Louisiana, and Texas. In September 2023, ABB announced it would partner with the Well Done Foundation to monitor methane and greenhouse gas emissions from orphaned wells in the United States. Process 

The WDF follows a five-step process to plug a well. It first identifies wells of interest in whichever state it is operating in, then researches well emissions of individual sites, alongside the history of the well, its depth, and materials needed to plug it, for a nine-month period. A bond is then posted and WDF adopts the well from the State. A budget is prepared for the project and a campaign is established to raise funds for the well's plugging and costs for surface restoration. Each campaign is funded entirely through donations and partnerships, with each well costing $30,000 to plug. Once the funding goal is reached, contractors are employed to carry out the plugging process and a gel is pumped through the well's piping, then filled with concrete. Following the sealing process, a methane monitoring platform, known by WDF as "Dorothy", is placed over the well and collects data on the methane emissions to see if the plugging operation successfully stopped methane leakage. WDF then works with surface land owners to restore the surface surrounding the well to its pre-drilling state. In the media
