An adapted elastomer compound, in which the adaptation is based at least in part on load performance data of a rotor/stator test coupon as evaluated on a test apparatus. The test coupon's stator section includes the original elastomer compound before adaptation thereof. The test apparatus includes a motor, a brake, and at least one sensor disposed to evaluate load performance data of the test coupon. The load performance data is the product of the process comprising the steps of: (a) rotating either the rotor section or the stator section on the test apparatus, wherein such rotation section actuates corresponding rotation of the other of the rotor section and the stator section; (b) applying a braking torque to the actuated rotor section or stator section; and (c) responsive to step (b), evaluating load performance data of the test coupon.

Tested products of PDM performance testing device

A method for evaluating load performance of a rotor/stator test coupon tested within a sealable test chamber containing test fluid. The test coupon preferably includes at least a partial length of a PDM stage. Alternatively, the test coupon may include a splined rotor/stator. The method includes rotating either the rotor section or the stator section in order to actuate corresponding rotation of the other of the rotor section and the stator section. Non-linear torque in the form of an acceleration torque and/or a braking torque may be applied to either the rotor section or the stator section. Downhole stall conditions may be simulated by selectively engaging and disengaging a second motor and flywheel to vary rotational torque applied to the test coupon. Load performance of the test coupon may be evaluated over time in such simulated stall conditions.

Stall simulator for PDM performance testing device

Disclosed is a method for determining properties of hydrocarbonaceous samples including a component prepared from: 1) the thermo-catalytic conversion of biomass, or 2) the pyrolytic conversion of biomass with subsequent upgrading. The determination of the property(ies) is by use of a near-infrared spectra based correlation.
