PETE 5103 Enhanced Oil Recovery Examen 2023

Extrait du sujet

1. a.

   Define: (i) interfacial tension, (ii) surface tension. (4 marks) (b) State the main parameters influencing primary oil recovery. (3 marks) (c) What factors determine the trapping mechanism of fluids in a porous medium during EOR processes? (4 marks)

2. Calculate the surface tension of water rise in a pore throat in a reservoir from at 2077 ◦C if the contact angle (θ) is 38 ◦, the capillary radius is 100 × 10 −6m, and the height of the water column is 12 m (Neglect the density of air compared with the density of water which is 1 g/cm 3.) Gravity acceleration constant, g is 980 cm/s
