In practice, mandatory uniting is set up with a participating party or a group of participants interested in the association of a pool or land. These parties then develop a unity agreement and a unitary operating agreement, which essentially corresponds to the documents of a voluntary unit. Then, before going to the appropriate government authority, they seek approval from at least the required percentage of the interest participants and the royalty holders necessary to comply with the legal requirements under which the matter is subject to the government authority. It records testimony, including expert testimony from geologists and reservoir engineers, on the basis of which the government agency makes its decision and issues an order (a judgment). In 2006, the Association of International Petroleum Negotiators (AIPN) established a Unitization and Unit Operating Agreement (AIPN Model Unit Agreement) form model.  The AIPN Model Unit Agreement should apply as a whole to single units, and the support guidelines expressly state that the AIPN Model Unit Agreement is an individual application and is not specific to jurisdiction. The single agreement should include provisions for the appointment of an expert and may even contain a proforma contract which is the first basis for negotiating the contractual relationship between the parties and the expert when the redefinition is referred to an expert. In the absence of such a proforma contract, it is essential that the parties explicitly set the terms of the expert`s appointment. In addition, the common authority (competent government authority) may, either automatically or at the request of a) a licensee or (b) a person legally entitled to enter into a single contract within a specified period of time, in an area outside the adjacent area, which includes part of an oil basin that enters the adjacent area. However, the standardization itself and the documentation of the unit agreement require careful consideration and consideration by all parties, given the difficulty and potentially contentious nature of the object in question. Article 2 of the AIPN Unit-Model Agreement provides that, in the event of the revocation of one of the contracts, the UUOA ceases unless the remaining parties to the contract agree (in accordance with the voting procedure in the UUOA) on the continuation of the UUOA, with the remaining group`s participation being 100% in the event of the revocation of a contract.
This means that the remaining group will have 100% of UUOA`s rights and obligations (including the right to production). This provision ensures that parties to the continuous oil contract can acquire the rights they need to continue unit operations under the UUOA. Some consider the AIPN approach to be problematic for any harmonization, since the group holding the remaining contract has no rights to the area covered by the revoked contract. In addition, the AIPN approach may be inconsistent with the host country`s oil legislation, which defines how the rights of the revocable contract are awarded in the event of revocation, as a general rule, the rights are returned to the host government. The Jubilee Field (Ghana) Unitization and Unit Operating Agreement (Jubilee UUOA), to which the Ghanaian National Oil Company (GNPC) is a party to the two treaties, provides that the Jubilee UUOA remains in effect in the event of expiry, termination or revocation of a contract, and that GNPC becomes the contract group that has expired/terminated/terminated/terminated and that all rights and obligations of the group on the expired/terminated/resiliated/resusctive contract are borne by all rights and obligations of the group.
