Drilling conditions vary, and so do the requirements for solids control equipment — high pressure for oil wells, gas-bearing mud for gas wells, and high sand content for water wells. Choosing the wrong equipment can reduce efficiency at best, or create serious safety hazards at worst. Many drilling companies fall into the “one-size-fits-all” trap during procurement, resulting in poor equipment compatibility.
Based on experience from over 200 projects, Black Rhino Industrial Co., Ltd. breaks down the key points for selecting solids control equipment tailored to different drilling conditions.
Selecting Equipment for Oil Wells: Focus on “Pressure Resistance + Contamination Resistance. Oil well drilling often exceeds 2,000 meters in depth, and the drilling mud is easily contaminated with heavy metals and crude oil impurities under high formation pressure. Ordinary equipment is prone to corrosion and blockage.
Black Rhino Industrial recommends an oil-well-specific solids control system: it uses high-pressure-resistant stainless steel separation tanks, paired with a 1200 rpm high-speed desander capable of withstanding 3 MPa operating pressure, and specially coated filtration elements that intercept crude oil impurities with 99% efficiency, preventing internal equipment contamination. After deployment in an oilfield, the equipment failure rate dropped from 3 times per month to 0.5 times, ensuring continuous operation for deep-well drilling.
Key Considerations for Gas Wells: “Gas Lock Prevention + Efficient Degassing.” Drilling mud in gas wells contains large amounts of methane and hydrogen sulfide. If equipment fails to degas promptly, gas locks can occur, causing downtime and even posing serious safety risks. Black Rhino Industrial’s gas-well solids control equipment is equipped with dual-stage degassing valves to continuously release gas from the mud. It also features gas detection sensors that trigger automatic alarms if harmful gas concentrations exceed safe limits.
In addition, the equipment uses anti-clogging nozzle designs to prevent cuttings carried by gas from blocking the flow channels. After deployment in a gas field project, downtime caused by gas locks decreased from 12 hours per month to just 1 hour, significantly improving operational safety.
Selecting Equipment for Water Wells: Focus on “High Sand Handling + Low Cost.” Water well drilling is relatively shallow (typically within 500 meters), but the drilling mud can contain more than 15% sand, and project budgets are usually limited. Black Rhino Industrial offers an economic solids control system for water wells: it uses large-diameter shale shakers (screen area 1.8 m²) to increase sand-handling capacity, while simplifying auxiliary systems to reduce equipment costs without compromising separation efficiency.
After procurement, a water well drilling team reduced mud sand content from 18% to 2%, and the equipment purchase cost was 15% lower than similar products, balancing efficiency and cost-effectiveness. If you are still unsure which equipment suits your drilling conditions, Black Rhino Industrial provides a free site evaluation service — engineers customize a selection plan based on drilling depth, mud type, and site layout, avoiding blind procurement. Currently, 85% of clients using customized selection have increased equipment utilization by over 20%, ensuring every investment is precisely matched to operational needs.
