Re: THE REQUEST of BP EXPLORATION ) Conservation Order No. 399
(ALASKA) INC., for an order
waiving Endicott Field Rules,
Conservation Order No. 202,
Rule 6(a).
August 5, 1997
APPEARING THAT:
1. BP Exploration (Alaska) Inc., operator of Duck Island Unit,
submitted a request received June 30, 1997 to waive the
requirement of Endicott Field Rules, Conservation Order
No. 202 (CO #202), Rule 6(a), Pressure Surveys, for all
remaining wells to be drilled in the Endicott Field, Duck
Island Unit.
2.Notice of the request was published in the Anchorage Daily
News on July 18, 1997.
3.No protests were filed with the Commission.
FINDINGS:
1. Rule 6(a) requires a pressure survey be taken on each well
prior to regular production.
2. Rule 6(c) and 6(d) require annual pressure surveys in each
governmental section and a key well pressure program to monitor
reservoir pressure in the pool.
3. A pressure survey in each new well may or may not be useful
for reservoir management purposes depending on where the
survey is taken in the reservoir.
4. Results and analysis of pressure monitoring have been
presented annually to the AOGCC.
5. Changes to the key well program have been proposed and
approved on occasion to meet needs of reservoir management
and to accommodate problems in a particular well.
6. Over 650 pressure surveys have been conducted in the
Endicott pool sine 1986. The operator has averaged
approximately 60 surveys per year.
CONCLUSIONS:
1. Pressure data for reservoir management purposes should
be acquired in wells and subzones throughout the
reservoir where appropriate to answer questions and
plan efficient development.
2. Pressure data from the Endicott Pool key well program is
reported regularly and is subject to annual review by
the Commission.
3. Rule 6(c) and Rule 6(d) are sufficient to provide pressure
data for reservoir management purposes.
4. Waiving the requirement of Rule 6(a) to measure reservoir
pressure in each new well will not cause waste or jeopardize
correlative rights.
NOW, THEREFORE IT IS ORDERED THAT:
Rule 6(a) of Conservation Order 202 is hereby repealed.
DONE at Anchorage, Alaska and dated August 5, 1997.
