Re: Shell Exploration & Production Company, Notice of Intent (NOI) P-2010-026?Review of
Multi-Mineral RDD Lease, Notice of Deficiency. ?
Dear Mr. Posey,
The Division of Reclamation, Mining and Safety (DRMS) has reviewed the Multi-Mineral RDD Lease
Notice of Intent to Conduct Prospecting Operations (NOI), No. P-2010-026, submitted December 30,
2010. The NOI has a few clarifications that need to be addressed in order for the notice to be considered
adequate to begin operations.
1. Initial review of the NOI submittal revealed that a hydrologic sampling and analysis plan was not
included with the original submittal. Please submit a hydrologic sampling and analysis plan that
complies with the requirements of Rules 3.1.6 and 3.1.7. Also, please specify proposed reporting
intervals.
2. Hydrology pad 138-4-298 is not identified/mislabeled on the East RD&D Pilot Facilities Plan
figure located in the figure section. Please provide a revised facilities layout figure that clearly
locates the 138-4-298 point of compliance.
3. Is the proposed location of a single L4 hydrology monitoring well sufficient to serve as an "early
warning" or should additional wells be installed to the northwest and southeast? If no other
wells are necessary please give a reason that explains why only one "early warning" well is
sufficient.
4. As discussed during the February 2, 2011 conference call between Harry Posey and Division
staff, the Division will require a pressure test after the production operation has ceased for each
well to assure that the integrity of the casing, cement and reservoir containment relative to the
overlying L4 WBI are all still intact.
5. In Section 62.4 Subsurface Reclamation, it states "Afterwards and after the reservoir is cooled
to an average temperature below the boiling point of water at formation pressure the voids
