Wellhead rating is 5000 psi for starting head (intermediate casing) and 10,000 psi for tubing head (10,000 psi is required not for drilling, but for injection, during which surface pressures will reach 5500 psi). BOPE is 10000 psi to match the wellhead rating and to allow for any remote chance that a higher pressure sand is encountered that would exceed 5000 psi shut-in surface pressures.

BOPE and drilling fluid system schematics on file. Waste Manaqement: Cuttings Handling: the cuttings will be processed through the onsite Grind and Inject facility and injected into disposal well B1-01. Surface gravels will be washed and stored for construction purposes. Fluid Handling: All drilling and completion fluids will be processed through the onsite Grind and Inject facility and injected into disposal well B1-01. Annular Injection: No annular injection is planned at this time. DRILLING HAZARDS AND RISKS: , Wellbore proximity comments are addressed under each MLOH section. Junk (auger tooth) was encountered in the B1-16 conductor - if junk is encountered, ensure all junk is fished prior to commencing drilling. Stuck pipe - UGNU sands, West Sak Sands - differential Coals - stringers throughout well, 4500' to Canning formations at 9500' tvd. Badami sands are overpressured - normally 12.2ppg mw required at TD. Pressure transition begins just above shallowest sand. Shallow sands typically pressured between normal and the 12.2 ppg required in lower sands. Maintain minimum mud weight and utilize latest techniques to manage lost circulation hazards in shallow sands (flow rates, tapered drill string). Weight up as wellbore pressures dictate, maintaining a 200 psi overbalance throughout. B 1-28 Producer - Multi-lateral PERMIT Hazards of well control and stuck pipe are managed by setting 7" casing above shallowest sand, before penetrating the full overpressure. Hazard of lost circulation is managed by proper techniques to maintain Iow ECD - ECD of 13.5 ppg noted to be maximum allowable to prevent lost circulation. B 1-28 Producer - Multi-lateral PERMIT ....
