Outset of a new exploration stage at Russian heavy oil and natural bitumen fields

DOI:

Currently the issues related to the perspective developments of heavy oil (HO) and natural bitumen (NB) fields are becoming more and more acute. The reason of that is correlated with the constant growth in oil price that in combination with beneficial Mineral Extraction Tax gives the increase towards the investment attractiveness of these projects. More that 2/3 of world oil reserves are considered as reserves of HO and NB categories. It should be noted that nearly half of them are referred to as non-recoverable reserves while applying modern commercially available field development procedures. Oil Company Rosneft has been paying a great deal of interest towards the so-called “hard-to-recover reserves”. It has summarized the domestic and international experience, has performed pilot jobs using the presently available procedures, conducted innovation activities in making the new process decisions.

Multiphase flow measurements: Vankor experience

DOI:

Provision for oil, gas, and water surface rate measurements from every production well is one of the most required issues for effective field development management. Due to the oil degassing during lift to the surface, gas and water breakthroughs, and high liquid rates, this task has become serious challenge for the Vankor wells. Preliminary, cyclone-based gas-separators have been considered in the field as the means for primary phase separation and consequent measurement of the each phase rate using Coriolis-based mass metering units. Another unit type for multiphase flow rate measurements uses Venturi tube and radioactive source for gas and water holdups measurement. Inflow performance relationships were plotted, average well drainage area was estimated, and reservoir properties distribution was précised based on the improvement of measurement accuracy.
