Abstract
A system for recycling a drilling fluid that includes a first cuttings storage vessel, a second cuttings storage vessel, and a module fluidly connected to the first and second cuttings storage vessels, the module having a valve configured to fluidly connect the first and second cuttings storage vessels. The module further includes a filter system configured to fluidly connect to at least the second cuttings storage vessel, and at least one pump to facilitate the flow of a fluid between the first and second cuttings storage vessels. Also, a module for use at a drilling location that includes a valve for directing drilling fluid between at least a first cuttings storage vessel disposed outside the module and a second cuttings storage vessel disposed outside the module. The module further includes a filter system for filtering the drilling fluid and at least one pump for facilitating the flow of the fluid between at least the first and second cuttings storage vessels.
