Investigating the impact of dissolved natural gas on the flow characteristics of multicomponent fluid in pipelines

Open Physics, 2019
The conventional equations for describing the flow characteristics of the mixtures merely consider fluid that is homogenic, if it is above the bubble point conditions but ignore that a system containing sub-micron sized gas or vapor bubbles distributed ...

Technologies for the oil and gas industry [PDF]

, 1998
This is the final report of a five-month, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). The authors performed a preliminary design study to explore the plausibility of using pulse-tube refrigeration to cool instruments in a hot down-hole environment for the oil and gas industry or geothermal ...

THE EFFECT OF FILLING THE GAS PIPELINE WITH CONDENSATE ON TRANSPORT PRESSURE

Rudarsko-geološko-naftni Zbornik
The analysis of the transportation of natural gases and associated petroleum gases indicates that, unlike natural gases, it is impossible to transport associated gases over long distances as a monophase state.
