Type of Operation

Description

Drilling

While performing a BOP test the annular did not pass the pressure test. The annular element was replaced and the new element tested without incident. Operations continued as planned.

Drilling

During a trip out of the hole, the Driller noted that the hole fill-up on the trip sheet was incorrect. Driller tripped back to bottom. Circulated bottoms up – no influx. Driller and Company Rep worked up a new trip sheet. New trip sheet was used and trip out of the hole was made with proper fill-up.

Drilling

The service rig crew were preparing to run in the hole with a tapered string of tubing. As part of the preparations the Driller and Company Rep compared the actual BOP configuration with the planned configuration in the workover program. They discovered that both sets of rams were Pipe Rams, and the plan called for one set of Variable Bore Rams and one set of Pipe Rams. They changed out one set of Pipe Rams for the Variable Bore Rams, tested the Variable Bore Rams and proceeded with the operation of running the tapered string of tubing.

Drilling

While performing a BOP function test one of the rig crew informs the Driller that there is a leak in one of the hoses at the accumulator manifold. The function test was stopped, the leaking hose replaced and the function test was completed without further incident.

Drilling

While doing a pre inspection of the BOPE that will be used for Oil Based Mud drilling it is noticed that the rubbers and components are not OBM compatible. The components are changed prior to use to avoid premature failure.

Drilling

While performing a choke drill prior to casing shoe drill-out, the rig supervisor simulated a hydraulic choke failure, instructing the crew to swap to the manual choke. Once at the manual choke, the rig crew realized that there were no DP or CSG pressure gauges and that without the use of radios, communication with the rig floor and driller was ineffective. Rig crew installed gauges on choke manifold and purchased hand radios to improve communication during well control events.
