METHOD OF DEVELOPING HYDROCARBON DEPOSITS Russian patent published in 2019 - IPC E21B43/25 E21B28/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry during development of oil, oil and gas and gas condensate deposits complicated by availability of water-hydrocarbon emulsions in productive formations by means of cyclic electromagnetic action. Method envisages monitoring of the product produced from the deposit – oil (gas condensate) and total volume of the liquid before electromagnetic action and after a certain period of time. Electromagnetic action is carried out cyclically, total volume of liquid (oil+water) and oil is determined without electromagnetic action and with electromagnetic action. Based on the obtained total liquid volume Ʃ^t₀Ql(t) and oil Ʃ^t₀Qo(t) measurements, the dependency curves lgƩ₀^tQo(t)=ƒlgƩ₀^tQl(t) are plotted based on these relationships, the relationship values are determined: F(e)=(lgƩ₀^tQo(t))/(lgƩ₀^tQl(t)) – at electromagnetic action and F(0)=(lgƩ₀^t1Qo(t))/(lgƩ₀^t1Ql(t)) – before electromagnetic action, where t₁ is the beginning time of the electromagnetic action on the deposit. Ratio F(e)/F(₀). At F(e)/F(₀)≤1 electromagnetic action process is terminated, and at F(e)/F(₀)>1 electromagnetic process is continued.

EFFECT: increasing oil recovery.
