The state of the art solids control system includes improved versions of this original equipment, first introduce into the oil industry many years ago. Although much more efficient and robust the core technology has change little over the past few decades.
Theory of Solids Control system:Drilling fluid and equipment maintenance cost can decrease greatly when proper solids control practices are utilized. From a fluid control stand point it would be desirable in most cases to remove all drilled solids. Although this is possible, it would be cost prohibitive. The goal of a solids control system is to achieve the balance between mechanical solids separation and dilution that will result in drill solids being maintained at an acceptable level with a minimum of cost.
Summary of Effective Solids Control system:
1.Obtain solids removal equipment for your operation.
2.Remove as many drilled cuttings as possible before being pumped back down the bore hole.
3.Do not by pass the shale shaker or other solid control equipment while drilling.
4.Use the smallest mesh screen possible on the shale shaker.This will change from formation to formation.
5.Maintain an adequate inventory of recommended spare parts.
6.Train & assign rig personnel to be responsible for equipment operation & maintenance.
The continuing trend of more stringent environmental regulations around the world will require more and more solids control system to be implemented to minimize haul off of drilling waste not to mention the cost saving on equipment such as mud pumps and mud motors.
The future path of solids control system will continue to increase the overall removal efficiency of undesirable solids from the drilling mud. This will include continued improvements in shale shakers and screen life. Research investigating alternate technology such as using vacuum techniques and different motions may prove more effective in the future.
