As outlined in an approved amended Application for Sundry Appr~ 028 Form 10-403), our intended kickoff point in _Monopod Platform #A-3rd2 has been moved up hole approximately 1337' MD from 4821' MD to 3484' MD. Moving the kickoff point up hole will not change the bottom hole location, and will only slightly change the intended well course. Also, this change will not affect the well kick calculations as the original calculations were based on a shoe depth of 3146' TVD and the proposed kickoff depth is 3032' TVD. The aforementioned changes will result in a more economic well while not compromising the integrity of the design. If you should have any questions, please contact Pat Ryan, Senior Drilling Engineer assigned to this project at 263-7864. Thank you for your attention to this matter.

The permit to redrill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout. prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (appro'ximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole.

A conservative estimate would be the MSP plus the hydrostatic pressure at the 9-5/8" casing depth (Hpcsg). Hpsh= MSP + Hpcsg HpshTM 440 + (3146'x0.50 psi/R) HPsh= 2013 psi This (Hpsh = 2013 psi) is less than the fracture pressure at the same shoe (Fpsh) and thus adequate to handle the well kick scenario. Hpsh = 2013 psi < Fpsh = 0.70 psi/ft x 3146' = 2202 psi. The maximum surface at TD (MSPtd)pressure is calculated based on a normal pressure gradient to total depth (7100' TVD) and the hole full of gas (estimated 1 ppg gas density).
