“…Currently, there are many methods for the selection of candidate wells [1,3,5,[12][13][14][15][25][26][27]: express analysis of the state of the well stock, diagnostics of water inflows by a graphical method, methods of statistical and probabilistic modeling, borehole diagnostics of water inflows. They also include construction waiting functions "productivity-water cut" and "reserves-water cut", selection based on modeling, selection of candidate wells due to water cut, an integrated and step-by-step approach to solving the problem of selection of candidate wells for WSOT.…”

“…At the second stage, the main reasons for watering wells are analyzed by applying both geophysical, hydrodynamic, chemical and graphical-analytical methods [1,27], and probabilistic-statistical analysis of field data. The use of statistical methods [6,12,15,20,22,28] allows using the previously derived regression equations, discriminant analysis and scatter diagrams of values to determine the sources of water cut in the well.…”

This paper describes a new algorithm for selecting candidate wells for water shut-off works. A new comprehensive methodology for the selection of candidate wells for water shut-off technology is proposed, consisting of 4 stages, where wells with excessive water cut are identified. The reasons for the water cut are determined, and the effectiveness of water shut-off technology on a potential candidate well is substantiated and predicted. The proposed method has been tested by the example of two wells in terrigenous reservoirs of a gas-oil field.

“…Various mathematical models (from statistical to numerical) are used by scientists and engineers of the oil and gas industry to improve the accuracy of predicting the effect of the use of polymer gels and optimize the volume of their injection in water flow restriction technologies [ 178 , 179 , 180 , 181 , 182 , 183 ]. Treatment modeling allows for the identification of the most significant factors, affecting the results of processing via selecting proper candidate wells and optimizing the process parameters of the treatment.…”

The use of gels in oil production processes has become a regular practice in oilfield operations and is constantly developing in all oil-producing countries of the world, as evidenced by the growth of publications and patent activity on this topic. Many oil production processes, such as hydraulic fracturing, conformance control, water, and gas shutoff, cannot be imagined without the use of gel technologies. Inorganic, organic, and hybrid gels are used, as well as foams, gel-forming, and gel-dispersed systems. The possibility of a broad control of structural and mechanical properties, thermal stability, and shear resistance by introducing microscale and nanoscale additives made hydrogels and hydrocarbon-based gels indispensable tools for oil engineers.

“…The Cenomanian reservoir of the Yamburg oil and gas condensate field (YOGCF), not being an exception to other large deposits located in the north of the West Siberian Plain, is therefore at a late stage of development, which is characterized by low reservoir pressures, a high degree of water cut, a low production capacity of the reservoir, collapsing reservoirs [1][2][3][4].…”

Like many of the fields in northwest Siberia, the Yamburg oil and gas condensate field is in the final production stages. This, therefore, results in an accumulation of a large amount of formation water in the inflow at the bottom of the well. Response surface analysis is used as a new technique to gain a detailed understanding of the relationships between combinations of two predictor variables and an outcome variable. This approach was applied to the Yamburg field to estimate the time of the gas-water contact, considered as the result variable, by taking into account two groups of predictive variables which correspond to the reservoirs grouped by their lithological characteristics. The results of the predicted gas-water contact time were compared to the expected gas-water contact time, the data of which were taken into account for the study. Using the model parameters as well as the three-dimensional response surface, which was constructed to facilitate and improve the interpretation of the results, it was then possible to predict the gas-water contact time under certain conditions.
