1. An analysis system for use in a drilling mud recirculation system, comprising:
- a drilling mud recirculation system comprising;
a processing unit comprising an entrance and an exit, comprising at least one component selected from the group consisting of filtering means for filtering said drilling mud;
cleaning means for cleaning said drilling mud;
a shale shaker;
at least one mud pit; and
, at least one reservoir in closable fluid connection with said internal flow;
at least one conduit passing through said processing unit;
said entrance and exit configured for fluid connection to a drilling apparatus via said conduit;
flow means for producing an internal flow of drilling mud through said conduit from said entrance to said exit, and, when said processing unit is fluidly connected to said drilling apparatus, a flow of drilling mud through said conduit from said drilling apparatus to said entrance and a return flow of drilling mud through said conduit from said exit to said drilling apparatus; and
optionally, at least one component selected from the group consisting of;
flow rate measuring means for measuring rate of flow of said drilling mud through at least a portion of said at least one conduit;
pressure measuring means for measuring pressure of said drilling mud in at least one portion of said at least one conduit; and
differential pressure measuring means for measuring a pressure difference in said flow of said drilling mud between two predetermined points along said conduit; and
a recirculation control system for controlling said processing unit and said flow means, comprising;
analyzing means configured to provide a real-time analysis of at least one chemical or physical property of drilling mud flowing through said recirculating system and to report and/or to record in real time results of said analysis and/or to compare in real time results of said analysis with a stored value, said analyzing means comprising at least one magnetic resonance device disposed about said conduit; and
a data connection configured to communicate said results of said analysis from said analyzing means to at least one receiver selected from the group consisting of said recirculation control system;
a receiving station not connected to said recirculation system;
an operator of said recirculation system; and
an operator of said analyzing means.

Abstract
The present application relates to an analysis system for multimodal analysis of drilling mud. Analyzing means, preferably and NMR or MRI device, are disposed about a drilling mud recirculation system and configured to communicate with the recirculation system'"'"'s control system. The analyzing means are used to determine the value of a predetermined quality parameter Q. If Q fails to meet a predetermined quality criterion, the analysis system instructs the recirculation system to perform an action to alter the properties of the drilling mud such that the drilling mud returning to the drill rig will meet the quality criterion.
