Some results of productivity increase in oil wells through application of a nanoparticle

V. R. Fataliyev

Results of laboratory experiments and to increase productivity in oil wells based on these results are presented in this article. Three models of nanosystems developed with the use of the clays from deposits in Azerbaijan were tested in these experiments. It is determined that the maximum productivity in oil wells is achieved while lifting a non - Newtonian liquid with a shear stress value ranging between 10.0 - 13.6 MPa and a plastic viscosity equaling to 16.8 - 23 MPa/s. Results of the laboratory experiments were tested in the oilfield conditions and in particular, in gaslift wells N104 and N110 of OGPU 28 May. It is determined that the maximum productivity is being achieved through addition of a nanocomposition built with clay and metal powder at a concentration of 1.5% into the production stream. It is found that the laboratory results correlate well with the field trials as it was able to increase the productivity in the range of 17-19% and decrease the gaslift gas injection rate 20-57%. An increase in gaslift well productivity, decrease of gaslift gas injection and an increase of in-between periods up to two times allow to consider the suggested nanocompositions a highly effective. The economic effect achieved through application of the suggested nanoparticles in the two wells totaled at 23500 manats.
