Forcing (a significant increase of liquid flow-rate volume) has long been successfully used in most oil fields as a very effective way to increase and maintain cost-effective oil production levels, however, currently many aspects of its application still require additional studying.
Forced fluid extraction (FFE) as a method of oil production intensification was first introduced in the oldest oil fields of Azerbaijan in 1933–1938. In order to obtain experimental data on the oil production forcing, the extraction of liquid from wells was increased by 50...70 %. At the same time, it was revealed that the positive effect of increasing oil production is long-lasting, which allowed making a conclusion that it is advisable to widely implement the method at other development sites.
At the moment, with the development of digital technologies to be applied in the fields development and the accumulation of an extensive historical database, it becomes possible to calculate numerous forecasting options of the impact of FFE on the picture of further facilities development. The authors of the article provide an example of using FFE in the hydrodynamic model as a way of determining the residual reserves localization in the forecast period and the potential for maximum coverage of the existing fund’s reserves in one of the areas of the terrigenous Devonian of the Romashkinskoye field.
