Current through Register Vol. 50, No. 6, June 20, 2024
A.
				  The base gas/oil ratio for a well recognized by the Office of Conservation as
				  an oil well is hereby fixed at 2,000 cubic feet of natural gas per barrel of
				  oil (2000/1). Any well recognized by the Office of Conservation as an oil well
				  which has a gas/oil ratio of 2000/1 or below will be allowed to produce its
				  base oil allowable without reduction. Any well recognized by the Office of
				  Conservation as an oil well which has a gas/oil ratio exceeding 2000/1 and from
				  which the operator cannot use or sell the gas will have its base oil allowable
				  reduced by assigning to such well an oil allowable determined by multiplying
				  the base oil allowable by the base gas/oil ratio and dividing by the gas/oil
				  ratio of the well.
B. If the
				  operator can use or sell the gas, the allowable which shall be granted to a
				  well which produces oil with a gas/oil ratio in excess of 2000/1, or to a well
				  which produces hydrocarbons from the gas cap of an oil pool, shall be
				  equivalent volumetrically to the quantity of hydrocarbons a well in the same
				  pool would be allowed to produce if it were producing oil with a gas/oil ratio
				  of 2000/1, each computed at reservoir conditions based on available data;
				  provided that reasonable estimates of reservoir conditions shall be used if
				  actual reservoir conditions cannot be determined from available data. Such
				  allowables shall be calculated as follows.
1.
				  Any well recognized by the Office of Conservation as an oil well which has a
				  gas/oil ratio exceeding 2000/1 will have its base oil allowable reduced by
				  assigning to such well an oil allowable determined by the following formula:

where:
= current depth bracket oil allowable for one well
when producing gas-oil ratio is less than 2000:1
Qo(2000+) = oil allowable for one
					 well when producing gas-oil ratio is greater than 2000:1
V = barrels of space occupied by one std. Mcf of gas at
					 reservoir conditions (res. bbls. per MSCF)
Rp = permissible gas-oil ratio for
					 an oil well (2.0MSCF/STB)
Ri = producing gas-oil ratio of
					 wells for which the allowable is being calculated (MSCF/STB)
Ro = solution gas-oil ratio at the
					 current bottomhole pressure (MSCF/bbl.)
B = volume occupied by one barrel of stock tank oil and its
					 solution gas at the current reservoir pressure (Res. bbl. per STB)
2. Any well recognized by the
				  Office of Conservation as a gas well and which is determined by the Office of
				  Conservation to be producing from the gas cap of an oil pool will be assigned a
				  volumetric gas allowable determined by application of the following formula:

Ao = number acres in oil unit
Ag = number acres in gas unit
Qo = current depth bracket oil
					 allowable for one well when producing gas-oil ratio is less than 2000:1
Ro = solution gas-oil ratio at the
					 current bottomhole pressure (MSCF/bbl.)
B = volume occupied by one barrel of stock tank oil and its
					 solution gas at the current reservoir pressure (Res. bbl. per STB)
V = barrels of space occupied by one std. Mcf of gas at
