Abstract: In some embodiments, an apparatus, system, and method may operate to transmit, using a first transceiver antenna, a common signal into a geological formation, and to receive in response to the transmitting, at the first transceiver antenna, a first corresponding nuclear magnetic resonance (NMR) signal from a first volume of the formation. Additional activity may include receiving, in response to the transmitting, at a second transceiver antenna spaced apart from the first transceiver antenna, the common signal transformed by the formation into a received resistivity signal, as well as transmitting, using the second transceiver antenna, a second corresponding NMR signal into a second volume of the formation different from the first volume of the formation. Additional apparatus, systems, and methods are disclosed.

Abstract: Analyzing crude oils and, more specifically, indirectly measuring asphaltene concentration in crude oils may be performed via nuclear magnetic resonance (NMR) techniques. For example, determining the asphaltene concentration of a crude oil sample having an unknown concentration of asphaltene and having the API gravity of about 20 to about 41 may be achieved by applying a measured NMR property of the unknown sample to a mathematical regression for asphaltene concentration in crude oil as a function of an NMR property according to the following equation where C is the asphaltene concentration, k is the Huggins constant that describes the solvent quality, [η] is the intrinsic viscosity. 1 T 1 = 1 T 2 ∼ 1 + [ η ]  C + k  [ η ] 2  C 2

Abstract: A microfluidic device and method is described to parallelize a pressure-volume-temperature (“PVT”) analysis such that a portion of the pressure, temperature and volume analysis is performed separately from others. The resulting PVT data is then recombined statistically for a complete PVT analysis. The microfluidic device may also obtain compositional data of the fluid to perform an equation of state analysis or reservoir simulations.
