Viscosity of a fluid is as important as the flow of money.  The thicker the fluid (viscous),  the slower the production and thus your earnings.

The fluid in a geological reservoir producing into a well goes through many changes during its production time and one of them is the viscosity.  In a nutshell; a producing reservoir is like a gas-chromatograph where small molecules like methane (one carbon) travel faster on its road to the well-bore then fat thick molecules like paraffin waxes (20 to 40 carbons), of course pressure and temperature depended.

Therefore it is imperative for production and reservoir engineers to know the reservoir fluid viscosity in their calculations to present a well-flowing model for their company so that they can do their economical engineering.  The earlier the better, and during production time for control purposes.

To do a fluid viscosity analyses you require a sample of the fluid and a tool to measure the viscosity.  Today this is dynamic due to nano-technology and powerful software programs.  The question is:  does the fluid or sample go to the tool to measure for analyses, or does the analytical tool go to the point of sampling?

Field PVT,  servicing the oil&gas, geothermal and coal-bed-methane industries uses existing techniques like slickline, wireline, coiltubing and well-flow-control to convey bottomhole samples to surface to do at wellsite: in-situ analyses.

We have existing methods for in-situ analyses on pressurized fluid samples (15000 psi 180 degC) for bubble&dew-points and now we can include viscosity.   A diagram of volume increase versus pressures drops with viscosity can be presented.

At wellsite we can follow up with our uniquely designed mini-welltest using our zero-flasher to get the liquid gas ratio’s, centrifugal Base, Sediment and Water (BS&W) and an avalanche of other analyses can be further designed depending on the type of well.
