A.
MEASUREMENT OF PRODUCTION.
(1) The operator of each producing well shall
maintain proper separators and stock tanks or metering devices and such
connections thereto as are necessary to measure the total production from such
producing well. Where metering devices are used, as herein provided, the
production may be commingled in a common storage system and if, upon a sale
therefrom, a variance exists between the measurement from the common storage
system and the total measurement of the production of all the producing wells
commingled in such common storage system, then such variance shall be allocated
back to each of the wells being commingled in the common storage system
proportionately to the production measured from each well.
(2) Where ownership is the same (working
interest and royalty interest), in lieu of maintaining separate separators and
stock tanks or metering devices for each well, well test results as outlined in
paragraph B, below may be used to allocate production for reporting purposes
from two or more producing wells commingled in a common storage
system.
B.
EQUIPMENT FOR TESTS:
(1) Each producing
well shall be so equipped that gas/oil ratio tests and bottom hole or other
pressure tests may be made.
(2) The
operator of two or more producing wells having the same ownership (working
interest and royalty interest) shall maintain proper separators and stock tanks
or metering devices and such connections thereto as will permit the adequate
testing of each individual well under usual operating conditions without the
necessity of closing in any other well for more than a 24 hour period. Such
separators, stock tanks or metering devices and connections thereto shall be
subject to approval by the Supervisor.
C.
USE OF METERS:
The use of meters for testing and for measurement of well
production shall be subject to and in accordance with the following
provisions:
(1) Only a volume
displacement type metering device or vessel which registers the volume of oil
passed through it in barrels or multiples thereof may be used.
(2) All meters shall be downstream of the
necessary separating or treating vessels. All meters shall be designed and
installed in conformance with recognized metering practices and shall be
subject to the approval of the Supervisor of the Oil and Gas Board.
(3) No meter used for oil production
measurement shall be directly or indirectly bypassed in such manner as to
permit oil to pass into common storage without first being measured.
(4) All meters and equipment affecting meter
accuracy shall be kept in good working order. Each meter shall be calibrated at
least once a month by means of a calibrated tank, a calibrated meter prover or
a master meter. When a meter is found to deviate in its recording by more than
two percent (2%), it must be adjusted to conform to the said tolerance
limitation of two percent (2%) or the meter calibration factor
corrected.
(5) The meter reading
and meter calibration factor in use at 7:00 a.m. on the first day of each month
for each meter shall be reported on the bottom of the Form 9 reporting the
monthly production from the wells being measured by such meter.
D.
AUTOMATIC CUSTODY
TRANSFER SYSTEMS AUTHORIZED:
Automatic custody transfer systems which automatically test,
sample, measure and transfer the production from the operator to the purchaser
are hereby authorized. Such systems may be used to transfer production from
individual wells or from common storage facilities as authorized in Rule 21 A
above. In the event the transfer is from such a common storage facility, the
allocation of production to the wells being produced into such common storage
system will be on the basis of the relationship of the measured production from
each well to the total measured production transferred by the automatic custody
transfer system.
Each such system will be equipped with a sampling device
which will take a representative sample of the total production passing through
the system in order that the specific gravity and the basic sediment and water
content can be determined.
Each such system will be equipped with a volume displacement
type metering device which registers the volume of oil passed through it in
barrels or multiples thereof. In addition to meeting all of the requirements
set out in Rule 21 C above which deals with the use of meters, said metering
device will be compensated for temperature, will be so equipped as to provide a
cumulative total of all oil transferred by such system and will have an
accuracy standard equivalent to the accuracy obtained in the measurements made
in calibrated stock tanks.
