On-site preparation

Pressure

Unexpected release of pressure during function test leading to personnel injury

Electrical

Use of no intrinsically safe laptop to program tools on the pipe deck. This can cause an explosion leading to injury or death of personnel, loss of SLB and Client assets.

Ensure Drop bar is of engineered design and designed for well conditions

Make sure to close swab valve as soon as the bar has dropped. IF Swab is not operating, close Master valve and fix swab valve with MV closed.

Ensure all valves lined up correctly prior to activating firing system

Use hole cover to prevent anything from being dropped in well during operation

If no indication at surface. If formation is taking fluid, the formation was perforated, if not, it wasn’t. Wait for indication at surface. Note the bubble hose located at the choke manifold.

If there is no indication of the guns detonating, follow contingency to POOH with live guns: Fish the bar and call town.
