Abstract
A method for monitoring the oleophilic fluid to aqueous fluid ratio of a drilling fluid includes selecting a sample of the drilling fluid that has been recirculated, measuring the NMR response of the sample of the drilling fluid and determining the oleophilic fluid to aqueous fluid ratio of the drilling fluid based at least in part on the NMR response.

A method for monitoring the oleophilic fluid to aqueous fluid ratio of a drilling fluid comprising:
- selecting a sample of the drilling fluid that has been recirculated;
- measuring the NMR response of the sample of the drilling fluid;
- and
- determining the oleophilic fluid to aqueous fluid ratio of the drilling fluid based at least in part on the NMR response.
A method for monitoring the oleophilic fluid to aqueous fluid ratio of a drilling fluid comprising:
- using an NMR spectrometer to measure the NMR response of the drilling fluid;
- comparing the measured NMR response to a predetermined NMR response correlated with an oleophilic fluid to aqueous fluid ratio;
- and
- selecting the oleophilic fluid to aqueous fluid ratio as the oleophilic fluid to aqueous fluid ratio of the drilling fluid.
A drilling fluid monitoring and handling system comprising:
- a mud pit coupled to a fluid analysis system;
- and
- a fluid analysis system coupled to the mud pit, wherein the fluid analysis system comprises an NMR spectrometer, wherein the fluid analysis system is configured to measure and analyze the NMR response of a drilling fluid.
