Other versions
(1) The size and the shape of any development units shall be such as will result in the efficient and economical development of the pool as a whole, and the size shall not be smaller than the maximum area that can be efficiently and economically drained by one well as determined by competent geological, geophysical, engineering, drilling, or other scientific testimony, data, and evidence. The department shall fix a development unit of not more than one hundred sixty acres for any pool deemed by the department to be an oil reservoir, or of six hundred forty acres for any pool deemed by the department to be a gas reservoir, plus a ten percent tolerance in either case to allow for irregular sections. The department may, at its discretion, after notice and hearing, establish development units for oil and gas in variance of these limitations when competent geological, geophysical, engineering, drilling, or other scientific testimony, data, and evidence is presented and upon a finding that one well can efficiently and economically drain a larger or smaller area and is justified because of technical, economic, environmental, or safety considerations.
Terms Used In Washington Code 78.52.210
- Department: means the department of natural resources. See Washington Code 78.52.010
- Development unit: means the maximum area of a pool which may be drained efficiently and economically by one well. See Washington Code 78.52.010
- Equitable: Pertaining to civil suits in "equity" rather than in "law." In English legal history, the courts of "law" could order the payment of damages and could afford no other remedy. See damages. A separate court of "equity" could order someone to do something or to cease to do something. See, e.g., injunction. In American jurisprudence, the federal courts have both legal and equitable power, but the distinction is still an important one. For example, a trial by jury is normally available in "law" cases but not in "equity" cases. Source: U.S. Courts
- Evidence: Information presented in testimony or in documents that is used to persuade the fact finder (judge or jury) to decide the case for one side or the other.
- Gas: means all natural gas, all gaseous substances, and all other fluid or gaseous hydrocarbons not defined as oil in subsection (12) of this section, including but not limited to wet gas, dry gas, residue gas, condensate, and distillate, as those terms are generally understood in the petroleum industry. See Washington Code 78.52.010
- Oil: means crude petroleum, oil, and all hydrocarbons, regardless of gravity, that are in the liquid phase in the original reservoir conditions and are produced and recovered at the wellhead in liquid form. See Washington Code 78.52.010
- Operator: means the person who operates a well or unit or who has been designated or accepted by the owners to operate the well or unit, and who is responsible for compliance with the department's rules and policies. See Washington Code 78.52.010
- Pool: means an underground reservoir containing a common accumulation of oil or gas, or both. See Washington Code 78.52.010
- Testimony: Evidence presented orally by witnesses during trials or before grand juries.
(2) The department may establish development units of different sizes or shapes for different parts of a pool or may grant exceptions to the size or shapes of any development unit or units. Where development units of different sizes or shapes exist in a pool, the department shall, if necessary, make such adjustments to the allowable production from the well or wells drilled thereon so that each operator in each development unit will have a reasonable opportunity to produce or receive his or her just and equitable share of the production.
