each of the pipes 14 and 16 for controlling the flow of fluid through the pipes 14 and 16 it is understood that the vessel 10 is designed to contain fluids at relatively high pressures to permit certain reactions to occur as will be described the vessel 10 is supported in a rack or frame 20 and is attached to the frame 20 in any conventional manner for the purpose of transporting the vessel 10 in a manner to be described fig2 depicts a series of method steps according to an exemplary embodiment utilizing the vessel 10 of fig1 the method relates to the drilling of a wellbore into a formation at a drilling location to find or remove hydrocarbon fluids as discussed above during these drilling operations drilling fluid usually in the form of oil or synthetic oil is pumped down through a drill pipe and into the borehole through a drill bit largely for the reasons indicated above when the drilling fluid is returned to the surface it brings up cuttings with it that must be removed from the fluid to this end and according to a step of the method the vessel 10 described above is located at the drilling location near the wellbore and receives the mixture of the drilling fluid and the cuttings the vessel 10 is then sealed and transferred to a separation site area that may also be at the drilling location and therefore near the wellbore alternately the vessel 10 can be transferred to a site relatively far from the drilling location in which case the vessel 10 would be transported to the site via a truck or railcar if an offshore operation is involved the mixture would be received in the vessel 10 on.
