In order to take into account the impact of the new reservoir data, unit agreements often contain provisions for redefining participation in the scheme and the participation of parties to the single agreement. The terms “pooling” and “unitization” tend to become words of particular importance, although the legal consequences are essentially the same, subject, of course, to the specific content of the statutes, which somewhat relay the procedures and consequences of the mandatory merger of those of coercive communities. But although the legal consequences are largely the same and the case is largely interchangeable from one situation to another, the physical results sought are very different. In some UKCS unit agreements, it is also customary to include provisions allowing a party to the single convention to request a change to the unit area, provided that the proposed extension area: the participation formula is at the heart of the single agreement. This is usually the most difficult problem to solve, but it cannot be standardized until it is agreed upon by all parties involved, particularly interested parties. The formula determines the proportion of unit substances that each participating party must receive and has generally arrived after long and laborious negotiations. The ideal solution would allocate production in such a way that each participant`s share of the unit`s production is exactly proportional to the value of the interest that each shareholder participates in the unit. The relative value of each participating shareholder`s contribution is not based solely on the amount of hydrocarbons that may be less than its reduction. Therefore, the value is determined not only by the productive acre, the feet of oil and gas on site, but also by additional factors such as the location on the structure, the amount of production already reached, the number of existing wells and the money invested in existing production facilities. An agreement of agreement contains provisions on when a redefinition should take place, including limiting the number of new provisions that can take place. However, certain unitation agreements (including some UKCS unification agreements) applicable to much smaller discoveries will determine market participation and equity interest, so that they are not subject to redefinition, since the cost of redefinition would amount to devaluing all the merits of redefining market participation. Mergers and mandatory associations arise from the application of state policing power to prevent waste and protect correlated rights. The constitutionality of these statutes is not in question today.
As a general rule, a mandatory pooling status requires the violent integration and thus the sharing of production from a drilling and distance unit in which a single well is permitted, at the request of a party holding stakes in the unit.
