In the drilling industry, a vibrating screen called shale shaker is the first equipment that does the filtration process. The purpose here is minimizing cutting solids in the mud. A shale shaker is the … Read the rest
The performance of a shale shaker depends on the large number of parameters. The most important variables affecting the capacity of a shale shaker are drilling fluid rheological properties, concentration and size distribution of solids, screen mesh and area, vibration … Read the rest
When using drill cuttings in order to determine formation lithology, representative sampling from all shale shaker screens, desander and desilter is essential. Procedures for correctly doing this and for correct washing and processing of samples are fully discussed in the … Read the rest
Two types of circulation techniques can be used for either a mud drilling system or an air or gas drilling system. These are direct (conventional) circulation and reverse circulation.… Read the rest
Mechanical solids control equipment selectively separate solids either through size differences, mass differences or both. Shale shakers use screens; hydrocyclones and centrifuges use centrifugal force. Understanding what are the key design factors and optimum operating limits for each of these … Read the rest
