Consenting Party, is a party in a JOA who agrees to participate in and pay its share of the cost of an exclusive operation. Non-Consenting Party means each Party who elects not to participate in an Exclusive Operation. Consenting parties have thus to pay the entire cost and liability of conducting any exclusive operation. An exclusion operation includes further operations on a well such as the deepening or sidetracking of a well. JOAs include a host of provisions governing the rights and obligations of non-consenting parties, including their rights to be re-instated, but usually at a high premium cost to the original costs.
