The main mechanism of it is 1) bettering the mobility control, 2) improvement of sweep efficiency (comparing to gas methods) and 3) the displacement efficiency (comparing to waterflooding). Many studies have been done in the past, but due to the increasing hard-to-recover field and facing difficulties during the production, the traditional WAG is facing problems that need to be coupled with. Implementation of new combinational methods and changes in the injection process to meet the needs have been developed during the last two decades. In this study, a simulation investigation has been done to compare proposed changes in the injection process to find the optimal injection scheme for the high heterogeneity - low permeability field. After analyzing the output of the simulation, the results show that each of the technologies has its advantages and disadvantages, and need to be applied according to the field constraints and requirement.

The advantage of the system is multitasking and using almost all the data coming from production facilities in real time. The main task of the system is to manage a group of wells taking into account their mutual influence to maximize oil production and reduce the negative impact of uncoordinated well operation without damaging the rational system of field development. A significant feature of the developed system is the creation of complex algorithms for predicting the main development indicators using artificial neural networks based on a combination of CRM (capacity resistance model), FFNN (neural network with direct communication), MBM (material balance model) and BFGS (Broyden-Fletcher-Goldfarb-Shanno algorithm) methods. During the pilot test on 10 wells, the modes were adjusted according to the recommendations issued by the system and the system confirmed its operability and effectiveness of application.

The studies were carried by using a fractional-rational diagram of relationship between stress and strain proposed in the Eurocode for a compressed concrete core inside a pipe and a symmetrical two-line diagram with limited area of fluidity for any values of an arbitrary flexibility of element and eccentricity of compressive force. On the carried research basis has been developed an effective numerical technique for determining the stress-strain state and the bearing capacity of compressed pipe-concrete elements. In calculation technique constructing, the task solution is reduced to system of nonlinear algebraic equations solving, relative to the deformation level in the most stressed section of the compressed concrete core section and the position of the neutral axis in this section. The efficiency of the proposed calculation method has been verified by numerous numerical experiments. It is shown that depending on the element's flexibility and the compressive force's eccentricity, at the moment of bearing capacity loss, the operation of the steel pipe can be both elastic and elasticplastic, and this is determined only by calculations using the proposed general method.

The method of finite elements that is realized in the engineering simulation software is used for research. The precise geometrical parameters of the drill pipes including a upset part and a screw joint; the character of the contact between a drill string and a well side; the physical and mechanical parameters of the rock; acting of the weight, the axial force, the bending moment and the torque are considered in to account during the calculation. The results of the calculation show that difference between the magnitudes of the normal stress on the drill pipe surface for mentioned above two cases is 45%; the difference between maximal bending is 65%.
