Effective solids control is the backbone of efficient and cost-effective drilling operations. A high-performing system directly impacts drilling fluid properties, equipment longevity, and overall wellbore stability. To accurately gauge the health and efficiency of your solids control equipment, several key performance indicators must be consistently monitored and analyzed. These metrics provide a clear picture of whether the system is removing drilled solids as intended or if costly inefficiencies are creeping into the process.
Drilling Fluid Properties and Centrifuge Performance
The most immediate indicators are found in the drilling fluid itself. Regularly testing the mud weight, viscosity, and sand content offers a direct reflection of solids control effectiveness. An unexpected rise in mud weight often signals an accumulation of fine, low-gravity solids that the primary shakers are missing. Similarly, increasing viscosity can indicate that colloidal solids are building up in the system, which can lead to a host of problems including reduced rates of penetration. For the centrifuge, the critical indicators are the density of the effluent (the liquid returned to the active system) and the dryness of the discharged solids. A dense effluent means the centrifuge is not effectively separating barite, while wet discharged solids suggest it is not operating at optimal G-force or feed rate.
Solids Removal Efficiency and Discharge Quality
The ultimate goal is to remove the maximum amount of drilled solids while conserving as much valuable liquid and commercial solids (like barite) as possible. The solids removal efficiency is a calculated metric that compares the volume of solids processed by the equipment to the theoretical volume of solids generated by the drill bit. A low efficiency rating points to equipment that is undersized, poorly configured, or improperly maintained. Furthermore, the physical condition of the discharged solids from shakers and dryers is a simple yet powerful visual indicator. The cuttings should be as dry as possible; overly wet cuttings represent a direct and expensive loss of drilling fluid to the environment.
Equipment Operational Parameters
Beyond fluid properties, the equipment itself provides vital performance data. For shale shakers, the key parameters are screen usage and G-force. An abnormally high consumption of screen panels suggests that the feed is too abrasive, often due to poor performance from downstream equipment like desanders or desilters. Monitoring the G-force ensures the shaker is providing adequate energy for effective solids separation. For the entire system, tracking the volume of valuable drilling fluid lost with the discharged solids provides a clear financial metric of performance, directly impacting the cost of mud maintenance and waste disposal.
