2024 Second Alert HiPo#05 MWD Engineer Fire & Explosion
On 10th February 2024 at approx. 7:40 AM, after the 2 MWD Engineers have completed checking and programming the MWD probe (consisted of a pulsar, 2 set of batteries & directional module), together with the Directional Driller (DD) they began to load the probe into the 6 ¾” Non-Magnetic Drill Collar (NMDC) which was placed horizontally on the strip woods on the ground. Once the probe fish head reached the NMDC shoulder, using the push tool, the DD & MWD Engineer # 2 pushed the probe further until it stopped. MWD Engineer # 1 (IP) went to the pin end of the NMDC to check if the probe seated correctly on the muleshoe. As the probe did not seat inside the muleshoe, the DD started hammering the probe using the push tool when suddenly an explosion occurred. Black powdery smoke from the explosion blew out from both ends of the NMDC, coming in contact with the injured person’s face and right eye. At the time of the incident, the injured MWD Engineer was wearing his safety glasses.
Always stay away from the line of fire Always ensure to use lubricant on the probe while loading into the collar Do not create sudden impact on the batteries Always place the NMDC horizontally on the pipe rack
Loading the MWD probe on the ground (not on the pipe rack) therefore not giving enough force for sliding the probe inside the NMDC. Not using lubricant on the probe centralizer therefore creating a friction, making it hard to slide the probe inside the NMDC. Hammering on the probe using the push tool causing sudden shock on the batteries. The injured person was standing in front of the pin end of the NMDC i.e. in the line of fire. The SOP covering this task was non-specific regarding the positioning of the MWD probe height.
