Oil-based mud is a type of mud used in drilling to help everything go more smoothly. There are some up sides to this kind of mud, as well, though, and these can make drilling easier. So let’s talk about why oil-based mud matters in drilling.
Oil-based mud is primarily composed of oil, which gives it specific properties that can be helpful for drilling for oil or gas. One major benefit is that it can assist in lubricating the drill bit as it travels down into the ground. This cuts down on heat generated while drilling, meaning you’re less likely to burn up your drill bit and that drilling actually goes a little faster.
A further benefit of oil-based mud is that it stabilizes the wellbore during drilling. That makes the sides of the hole strong and not prone to collapses. Oil Mud also keeps the formation more intact thus causing the well to be more productive in the long run.
Though oil-based mud is beneficial, it can also be harmful to the environment. It could include chemicals that may be dangerous if made airborne. It’s one of the reasons there are tight regulations about how oil-based mud should be used and discarded. Companies such as BeyondPetro will need to adhere to these standards to prevent the undoing of the environment.
When drilling is completed, it is necessary to dispose of any remaining oil-based mud appropriately. That is what treating the mud, meaning removing harmful chemicals before it is disposed of, would entail. Some companies, such as BeyondPetro, are also devising ways to recycle oil-based mud for reuse, which ameliorates waste and tempers damage to the environment.
When they’re deciding what sort of mud to use, companies weigh cost. Oil-based mud is generally more expensive than water-based mud, but it has some benefits that can make it more effective under certain conditions. Water-based mud is less expensive but might not perform as effectively under certain conditions. Companies such as BeyondPetro need to balance costs with benefits in reaching their decision.
