Article

We have used proton magnetic resonance relaxometry to study the dependences of the spin–lattice and spin–spin relaxation times T1,2 on viscosity and concentration of asphaltenes + resins in crude oils, in particular from the Bach Ho field (Vietsovpetro joint venture), and we have derived equations relating them. We have refined the correlation ηT1,2 = const/T. The viscosity ν = η/ρ in these crude oils is exponentially proportional to the concentration of asphaltenes + resins.

Key words

relaxation viscosity asphaltene concentration correlation ηT1,2 = const/T
