On-site Application Case of Oil-based Mud Non-Landing System

In oil and gas drilling operations, oil-based mud is widely used due to its excellent lubricity and high temperature resistance, but the compliant treatment of oil-based cuttings has always been a major environmental pain point in the industry. The traditional "landing-collection-transportation" treatment mode is not only inefficient, but also has the risk of secondary pollution. As the professional mud non-landing system manufacturer, TR Solids Control has launched an efficient and environmentally friendly oil-based mud non-landing system, realizing the source reduction, resource utilization and harmless treatment of drilling waste.

System Equipment: Efficient Separation, Turning Waste into Treasure

The system integrates shale shakers, centrifuges, conveying devices, and an electrical control system to form a closed, continuous treatment process. The mixture of oil-based mud and cuttings returning from the wellhead first passes through multi-stage shale shakers for coarse, medium, and fine solid-phase separation, removing most of the cuttings. Subsequently, the liquid phase enters high-speed centrifuges to further separate fine solid particles. The purified oil-based mud can be directly reused in the drilling circulation, with the recovery rate exceeding 95%. The separated solid cuttings have extremely low oil content, meeting environmental emission standards, and can be safely landfilled or utilized, truly achieving "mud non-landing."

Application Advantages: Cost Reduction, Efficiency Improvement, Compliance and Environmental Protection

The project is located at the oil and gas field in China. The drilling operation uses oil-based drilling fluid, generating a large volume of cuttings per well. Local environmental authorities impose strict requirements on the discharge of oily waste. Traditional treatment methods could not meet compliance standards, and the customer needed to reduce cuttings treatment costs and improve drilling efficiency. TR Solids Control, as the mud system manufacturer, customized an integrated oil-based mud non-landing treatment system for the project conditions. The equipment includes vertical cuttings dryers, screw conveyors, decanter centrifuges, etc., achieving the closed-loop operation of "drilling-treatment-recovery-discharge."

1. Environmental Compliance: Through high-G drying and centrifugal separation, the oil content of cuttings is stably controlled below 1%, meeting national hazardous waste treatment standards and achieving compliant discharge of cuttings.

2. Efficient Resource Recovery: The system efficiently recovers useful components such as base oil and barite from the oil-based mud, with a recovery rate exceeding 95%, significantly reducing drilling fluid procurement costs. The single well can save hundreds of thousands of yuan in consumable expenses.

3. Improved Operational Efficiency: The system adopts the modular integrated design with the processing capacity of 30–60 t/h, adaptable to different drilling conditions. Drilling and treatment proceed simultaneously without downtime, effectively shortening the drilling cycle.

4. Intelligent Operation and Maintenance: Equipped with an explosion-proof electrical control system, the system allows real-time monitoring of operating parameters, is easy to operate, reduces labor maintenance costs, and features high stability suitable for harsh field conditions at oilfields.

From the on-site operation data, the system operated stably during the whole project cycle, the cuttings treatment effect met the standard, the customer's environmental acceptance passed at one time, and the recovery rate of drilling fluid was significantly improved. The comprehensive treatment cost was reduced by more than 30% compared with the traditional process, which was highly recognized by the customer.

The oil-based mud non-landing system is key to the green transformation of the drilling industry. It not only solves the problem of environmental compliance, but also realizes the dual value of resource recycling, cost reduction and efficiency improvement. With over 20 years of experience in the solid control field, TR Solids Control has comprehensive capabilities in technology R&D, manufacturing, and on-site services. The company offers customized mud non-landing solutions tailored to different drilling conditions, providing environmentally friendly, efficient, and reliable solid control equipment support for oil and gas drilling projects worldwide.
