The EMW is 11.9 ppg at 5840' TVD (ALl-O1 TD). Max. surface pressure with gas (0.1 psi/ft) to surface is 3016 psi. Variance request • BPXA requests a variance to the provisions of 20 AAC 25.036 (d)(4) THROUGH TUBING DRILLING AND COMPLETION. This is regarding the function pressure test requirement after the use of BOP ram type equipment for other than well control or equivalent purposes. The variance will not apply when the routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadvertently closed on a tool joint during routine operations.) While drilling 1L-25 it will be routine to close the 2-3/8" combi rams (pipe/slip) on the BHA during deployment and undeployment. These activities will not compromise the integrity of the BOP equipment. Managed Pressure Drilling Managed pressure drilling techniques will be employed to provide constant bottom hole pressure by using ~ 8.6 ppg drilling fluid in combination with annular friction losses and applied surface pressure. Constant BHP will be utilized to reduce pressure fluctuations to help with hole stability_ Applying annular friction KRU 1L-~ AL1-01, AL1-02, and AL1 Sidetrac~ Coiled Tubing Drilling and choke pressure also allow use of lighter drilling fluid and minimizes fluid losses and/or fracturing at the end of the long well bores. A hydraulic choke for regulating surface pressure will be installed between the BOPE choke manifolding and the mud pits and will be independent of the BOPE choke. This well has a tubing retrievable sub-surface safety valve that will be utilized to facilitate BHA deployments and liner running. However, it is still possible that deployment of the BHA under trapped wellhead pressure would be necessary. Pressure deployment of the BHA will be accomplished utilizing the BOP pipe/slips (2- 3!8" rams, see attached BOP configuration). The annular preventer will act as a secondary containment during deployment and not as a stripper. Operating parameters and fluid densities will be adjusted based on real-time bottom hole pressure measurements while drilling and shale behavior. The following scenario is expected at the 1L-25A TD: • Estimated reservoir pressure: 3470 psi at 5870' TVD, 1.1.4 ppg EMW. ~~(~~ ~ ~/~'~r~~ ~y ~~~,>°~'~ t'~'k~ • Expected annular friction losses while circulating: 1044 psi (based on 90 psi/1000 ft) ~ i~• r y r~~ • Planned mud density: 8.6 ppg equates to 2625 psi hydrostatic bottom hole pressure. • While circulating 8.6 ppg fluid, bottom hole circulating pressure is estimated to be 3669 psi or 12.0 ppg ECD • When circulation is stopped, a minimum of 1044 psi surface pressure will be applied to maintain constant BHP. • !
