1. A mobile drilling waste management system comprising:
- a trailer, the trailer comprising;
an inlet configured to receive fluids from a drilling rig;
at least one centrifuge in fluid communication with the inlet, wherein the at least one centrifuge comprises a first centrifuge and a second centrifuge;
a solids catch tank, the solids catch tank receiving solids separated by one or more of the centrifuges;
an outlet in fluid communication with one or more of the centrifuges;
a slurry tank, the slurry tank receiving a liquid effluent from the second centrifuge; and
a solids switch capable of directing solids separated by the first centrifuge to either the solids catch tank or the slurry tank.

Abstract
A mobile drilling waste management system including a trailer having at least one centrifuge and a solids catch tank receiving solids separated from drilling fluid by one or more of the centrifuges. And a method of reclaiming drilling fluid including pumping drilling fluid contaminated with solids onto a trailer, separating the contaminant solids from the drilling fluid with at least one centrifuge located on the trailer, directing the contaminant solids to a solids catch tank located on the trailer, and pumping the drilling fluid off of the trailer.

17. A method of reclaiming drilling fluid comprising:
- pumping drilling fluid contaminated with solids onto a trailer;
separating at least a portion of the solids from the drilling fluid with at least one first centrifuge and one second centrifuge located on the trailer;
directing the separated solids to a solids catch tank located on the trailer; and
pumping the drilling fluid off of the trailer;
wherein during the step of pumping said drilling fluid contaminated with solids onto the trailer, the trailer comprises;
an inlet configured to receive fluids from a drilling rig;
the first centrifuge in fluid communication with the inlet;
an effluent tank receiving a liquid effluent from the first centrifuge;
a piping assembly configured to direct either fluid from the inlet or effluent tank to the second centrifuge;
a slurry tank, the slurry tank receiving a liquid effluent from the second centrifuge;
the solids catch tank receiving solids separated by the second centrifuge;
a solids switch capable of directing a solid separated by the first centrifuge to either the solids catch tank or the slurry tank; and
a programmable logic controller;
separating solids from the drilling fluid in the first centrifuge and the second centrifuge;
discarding the solids from the second centrifuge into the solids catch tank;
directing effluent fluid from the first centrifuge to the effluent tank;
directing effluent fluid from the second centrifuge to the slurry tank; and
pumping fluid from the slurry tank to an outlet positioned on the trailer. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
