Even with the most stringent safety measures, accidents can happen in the workplace. Furthermore, any mishap at an oil drilling site can swiftly escalate into a catastrophic event because of the tremendous pressure and flammability dangers prevalent there. As an example, consider the tragic Deepwater Horizon incident. While held up as a paragon of safety procedures, an oil rig experienced a catastrophic failure.
Once a blowout has started in an oil well, stopping it is a high-stakes, high-cost, high-risk endeavor. At this time, your only option is to leave the area. Preventing a blowout in its entirety is preferable to dealing with one after it has already occurred. You can significantly lower the likelihood of a blowout by taking certain precautions and following all safety rules and guidelines.
In current wells, the downhole fluid levels are managed by adjusting the hydrostatic pressure generated by the column. If the drilling mud pressure equilibrium is off, formation fluids can enter the wellbore and travel up the annulus and even into the piping system itself. This is commonly referred to as a “kick.”
Now that we’ve discussed how a blowout occurs during drilling operations let’s look at some ways a blowout can be avoided during a drilling operation.
1. Learn To Identify Warning Signs
As the head engineer in an oilfield, it is imperative that you are aware of the symptoms that an oil well blowout is imminent. For instance, if the fluid level in the wellbore suddenly increases for no apparent cause, this could signal the start of a kick, which could lead to a blowout.
Alterations in oil well pressure or the rate at which the drill bit is spinning could also indicate trouble. Drilling should be halted, and the oil well’s pressure should be checked regularly to detect any abnormalities. If the pressure seems to build, the annular BOP should be closed.
2. Make Sure Your Equipment Is Clean & Maintained
For optimal machine performance, BOP gear must undergo obligatory routine inspection and maintenance. As part of routine maintenance, the pressure inside the BOP structure, the hydraulic connections, as well as the BOP stack must be checked. When performing checks and maintenance on the equipment, refer to the instructions provided by the manufacturer.
Blowout preventers that are dirty or malfunctioning cannot do their duty and contain high-pressure gas and oil. When a metal drill is used to bore through rock, microscopic metal shavings are chipped off and mixed with the soil and liquid forced through the BOP.
The BOP’s interior, especially the elastomer sealant, is susceptible to damage from these shavings, which can lead to a leak. A downhole magnet can clear up the mud and eliminate any metal debris, making it less likely that pressure would leak out of the well.
3. Understand How Your Equipment Works
Nobody knows what k weather conditions or other problems you’ll encounter on any particular day at the drilling site. Nevertheless, you can get a glimpse of what might happen with the help of a simulation. Take the BOPs for a spin in some computer simulations and see how they react to harsh conditions. (A similar simulation involving the Deepwater Horizon was conducted by the Southwest Research Institute.)
One can be better prepared for a prompt response if they are aware of the expected behavior of their BOPs in the event of an emergency. Some elastomers and BOP parts are only suitable for use in specific environments. Any attempt to push them beyond their boundaries risks a breakdown.
4. Be Prepared For An Emergency
Ultimately, training and education are of paramount importance and cannot be emphasized enough. You and everyone else at the drilling site must be aware of and follow all necessary safety protocols at all times. To ensure that everyone is always prepared, it is important to hold regular drills and refresher training.
5. Understand What Your Worksite Requires
For the protection of your employees, what tools do you lack? The number of BOPs needed and the maximum allowable pressure will vary depending on the scope of your activity. While the specifics may vary, there are a few fundamentals of blowout control system that must always be present on the job site:
- Equipment for use in drilling, including spools and API
- BOP Rams
- Annular BOPs
Before being released to the public, oilfield machinery is put through years of rigorous testing. Therefore, accidents and catastrophes are quite uncommon. Failures are rare, but when they do happen, the consequences can be devastating. The most effective course of action is to advocate for and implement measures to reduce the risk of oil well explosions.
