Oil-water simultaneous production, a new technology developed abroad since 1990s, is primarily applied to eliminate or control water coning in reservoir with bottom water.

The study of the critical production and water breakthrough from an oil well in a bottom water reservoir should be based on sound understanding of water coning shape in it first of all.

Application of material balance method to nitrogen anti-water-coning technology;

Commingled production of oil and water in bottom water coning reservoirs;

Main parameters affecting bottom water coning in heavy oil reservoir;

A Study on the elimination of barrier to bottom water coning;

Calculation method for the water cone height of bottom-water reservoir;
