Abstract: Viscosity assemblies may be used to determine the viscosity of a sample fluid at a surface location under one or more downhole conditions prior to pumping or flowing of the sample fluid downhole. A viscosity assembly may include a bob assembly disposed in a container that includes a bob disposed about a magnet rotor that rotates when a shear force is applied by the flow of the sample fluid in the container. A stator coil may receive a control signal that induces a force or a voltage that causes the magnet rotor to rotate the bob by a predetermined distance to position the bob from the rotated position back to the initial position.

Abstract: A method for scheduling tasks to a cyclic schedule, comprising maintaining a request queue, a count, the count being initialized to a given limit, and an index of a current time slot within the schedule. Periodically, if the request queue contains a reference to an urgent task among the tasks, that reference is removed from the request queue and the urgent task is dispatched and if the request queue is empty, the index is advanced to the next time slot within the schedule. If the next time slot is statically assigned to a task among the tasks, that task is dispatched, and if the next time slot is unassigned and the count is below the limit, the count is incremented and the index is further advanced to the next but one time slot.

Abstract: A mud retort assembly includes a retort that heats a fluid and thereby generates vapors, a condenser in fluid communication with the retort to at least partially condense the vapors and thereby generate a liquid, a condensate collector that receives the liquid and residual vapors via an outlet pipe of the condenser, and a collector plug having a frustoconical body that extends partially into the condensate collector at an opening to the condensate collector. The collector plug defines a central aperture that receives the outlet pipe and has an annular flange extending radially outward from the frustoconical body to rest on the condensate collector at the opening.
