Technology has facilitated activities in different sectors, including the oil and gas industry. One of the major technological inventions has been portrayed in how drilling takes place. In the past, it required a lot of effort and resources to drill out oil due to a lack of comprehensive equipment. Today, there are drilling systems in place that make the work more comfortable and more efficient. This has helped cut on the cost and reduce the risk of injuries such as slip and fall by a larger percentage.
The most recognizable advancement in the drilling industry is the invention of brine based drilling fluids. This type of fluids has proven fundamental in work-over and under-reaming operations since they aid in the formation protection, which is usually a more significant issue during high angle drilling maneuvers. The following are the reasons why brine has taken over geotechnical engineering.
Cost Efficiency in Drilling
Several renowned drilling engineers have ascertained brine-based drilling fluids’ ability to reduce the cost of drilling by a substantial amount. Engineer Ryan of Encana drilling works admitted that brine format compared to actual fluid prices costs about 360% less, reducing the overhead expenditures of the entire drilling process. Ryan indicated that their company incurred a reduced cost of up to 27% in every lateral meter drilled for a given well when they used brine.
Reduced Formation Damage
Although it is inexorable to prevent the invasion of reliable components into the formation, an almost zero percent of protection is evident when using brine-based fluids. In addition to the fluid, drilling engineers need to design accurate models, particularly for the lateral and horizontal wells, to reduce the formation’s destruction.
Reduce Injuries among Workers
Drilling works are risky, mostly when the machinery does not efficiently work as it should. It is essential to consider all the safety precautions before engaging in a given drilling work to avoid being a victim of work-related injuries. Some people have been impaired due to miscalculations and system failure in drilling sites. This prompted thorough scrutiny and inspection of all the equipment used in the procedure. Drilling fluids have, to a great extent, reduced the malfunction of mechanical equipment, and as such, the injuries during drills have magnificently reduced. One of the notable and high rising drilling fluids over the last few years is brine. This fluid has proven effective in minimizing corrosion and wear of equipment at rig sites.
Without using standard fluids during wells’ drilling, the chances are that the formation will blow out. The main benefit that a suitable drilling fluid brings is that it wields hydrostatic pressure to the well, which balances the pressure exerted by the formation to reduce the influx. If the drilling fluid exceeds the standard weight due to increased density, the chances are that it will cause the formation to fall. Therefore, it is advisable that accurate modeling of the structures, especially the drill-in point, be done and efficient fluids such as brine. Brine-based fluids can maintain the pressure exerted to balance the natural formation forces that cause damage.
