Drilling fluid conditioning systems and methods

A drilling fluid conditioning system for a well system, the system comprising:

• a return conduit configured to receive drilling fluid recirculated from a wellbore of the well system;
• a drilling fluid pre-chilling system in fluid communication with and downstream from the return conduit, wherein the drilling fluid pre-chilling system comprises a cooler configured to transfer heat from the drilling fluid to a heat sink, a solids separator in fluid communication with and upstream from the cooler, and a nonrotative pump for fluidically pumping the drilling fluid from the solids separator to the cooler of the drilling fluid pre-chilling system;
• and
• a solids control system in fluid communication with and downstream from the drilling fluid pre-chilling system, wherein the solids control system is configured to separate at least some solids from the drilling fluid;
• wherein the nonrotative pump of the drilling fluid pre-chilling system is powered by a flow of pressurized motive fluid, and wherein the flow of pressurized motive fluid comprises a flow of pressurized drilling fluid received from a suction tank of the drilling fluid conditioning system located downstream from the drilling fluid pre-chilling system.

• and
• a solids control system in fluid communication with and downstream from the drilling fluid pre-chilling system, wherein the solids control system is configured to separate at least some solids from the drilling fluid;
• wherein the solids catcher comprises a pressure vessel, a drilling fluid inlet for receiving the drilling fluid, a solids collector for receiving at least some solids from the drilling fluid, and a drilling fluid outlet, and wherein the solids catcher comprises a jetting pump at least partially received in the pressure vessel for at least partially evacuating the solids collector of the solids catcher.
