The diamondoid compound content of a hydrocarbon gas sample stream is measured in a process and apparatus for the controlled precipitation and collection of diamondoid compounds.

Method and apparatus for measuring diamondoid compound concentration in

A method and apparatus are provided for locating a solvent injection apparatus within a natural gas wellbore to reduce the deposition of hydrocarbonaceous solids which are at least partially soluble in the solvent.

A method and apparatus for determining certain fluid flow parameters for naturally fractured media. Specifically provided is a method and apparatus to measure the flow rate, pressure drop, fracture aperture, fluid supply temperature and sample-loading force. A naturally fractured media core sample is obtained for testing and cut into a pair of core blocks having mating fractured forces. The fracture face of the core sample prepared in this manner, yields a more representative surface for flow study, eliminating the problem arising from the fact that most fractures cut across round core samples, resulting in an unnatural, elliptical surface for evaluation. A flow cell assembly is provided to receive the pair of core blocks and secure them during the measurement operation. The flow cell assembly permits adjustment of the fracture aperture to facilitate comprehensive evaluation.

Method and apparatus for measuring fluid flow parameters through

A floatation apparatus is disclosed wherein a buoy for maintaining the near surface position of marine equipment is mounted on a hydrodynamically advantageous V-shaped frame to reduce frictional drag associated with towing surface equipment.

Floatation apparatus for marine seismic exploration

An apparatus is provided wherein one air supply is used to supply compressed air for a plurality of multi-size seismic pulse generators.
