There are two main types of Missouri affidavits related to the cessation of production and plugging of wells: 1. Missouri Affidavit of Cessation of Production: This type of affidavit is filed when the operator or leaseholder voluntarily decides to cease the production activities from an oil or gas well. It includes details such as the well's location, well identification number, date of last production, and any additional information required by the regulatory agency. By filing this affidavit, the operator declares the discontinuation of production and complies with the necessary regulations. 2. Missouri Affidavit of Plugging of Well Specifying Date of Last Royalty Payment: This affidavit is specifically used when a well is permanently plugged due to various reasons, such as exhausted resources, safety concerns, or environmental regulations. Along with providing information about the well's location and identification, it also specifies the date of the last royalty payment made to the concerned parties. Filing this affidavit ensures the proper closure of the well and the termination of any royalty payment obligations. In both cases, these affidavits are crucial in maintaining transparency and accountability within the oil and gas industry. They provide a formal declaration of the well's status and ensure compliance with the regulations set forth by the state of Missouri.
