<p>Disclosed is a system and method for improving the separation of drilling fluid from drill cuttings so that drilling fluid can be recycled without impacting the rheological properties of the drilling fluid. The system comprises a shaker (10). The shaker (10) comprises a shaker screen (10a) and support system for supporting contaminated drilling fluid. First and second fluid collection systems are positioned beneath the shaker screen (10a) and support system to collect drilling fluid from a first and second section of the shaker screen (10a) and support system. At least one of the first and second fluid collection systems includes a hopper. The second fluid collection system includes a screen extension (11) and screen for retro-fit connection to the shaker screen (10a) and support system for extending beyond an original length of the shaker screen. Additionally the second fluid collection system includes a vacuum system for subjecting the screen extension to vacuum pressure and collecting fluid from the screen extension.</p> |
