be given to ensure that the system is hydraulically balanced, capable of making both a scalp cut and a ine cut , and that the system has sufi- cient drilling luid mixing and re - circulat ing capacity. Shale shakers and other solids control equipment should never be bypassed while drilling . Various mesh sizes should be used on the shaker as condit ions change f rom format ion to format ion requiring operators to maintain a va - riety of screens to be kept on hand. Furthermore, an adequate inventor y of recommended spare part s and screens should always be kept en - hancing operat ions . To achieve effective solids control , the following should be deployed: 1. Obtain an effective, dependable, and durable solids control system. 2. Ensure that the solids control system acquired is: a. Hydraulically balanced b. Is capable of making both a scalp cut and a ine cut . c. Has suficient drilling luid mixing and re-circulating capacity. 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 and will require operators to maintain a variety of screens on hand. 5. Maintain an adequate inventory of recommended spare parts and screens. 6. Certify and assign rig personnel to be responsible for equipment operation & maintenance. a. Request equipment commissioning and training for your OEM. b. Discuss possible written training programs that may be available from your OEM. By employing each of these steps, operators can achieve enhanced rig performance, improved rates of pen- etration, reduced waste disposal costs, and reduced mud costs.
