Part 8 U.K. Oil activities

Chapter 7 U.K. Reduction of supplementary charge for certain new oil fields

Interpretation U.K.

354 “Ultra heavy oil field” U.K.

(1) In this Chapter “ultra heavy oil field” means an oil field with oil at—

(a) an API gravity below 18 degrees, and

(b) a viscosity of more than 50 centipoise at reservoir temperature and pressure.

(2) For that purpose API gravity, in relation to oil, is the amount determined by the following calculation—

where G is the specific gravity of the oil at 15.56 degrees celsius.
