The paper gives a definition of the generalized safety level of a process facility, based on the provisions of existing regulations. The provisions of the international and domestic normative documents and standards regulating the development of the safety system elements of a dangerous production object is analyzed. The results of the analysis served the basis for giving recommendations on the choice of target values range for safety indicators of emergency shutdown system (ESD), with account of the total degree of a technological object danger, which is expressed by its belonging to a particular hazard class, category of explosion and fire hazard.

The proposed recommendations are in full compliance with the existing regulatory base, and provide for specification of the target values range for such safety indicators as risk reduction factor (RRF), the average probability of failure on demand (PFD), etc. The recommendations can be used at the ESD design stage as a part of the automated control system of technological processes (ACSTP), as well as during conducting risk analysis procedure for hazardous production facilities.

Keywords: hazardous production facility; emergency shutdown system (ESD); safety; explosion danger; fire danger; risk; SIL; SIS; RFF; HAZOP.

The work is devoted to the further development of mathematical schemes for analyzing equilibrium barometric processes in dispatch control systems for ESP equipped wells. It is based on the transition from linearized relationships to quadratic correlations corresponding to the classics of pipe hydraulics.

The goal of the study is to give a new comprehensive description of the equilibrium barometric states of a well operation with a frequency-controlled ESP based on the transition to more accurate approximations of the kinetic pressure losses in the lift segments by second-order models.

The constructed updated mathematical model of the "inflow-elevator-ESP-wellhead" class system and its digital implementation are focused on the use in monitoring and control of closed well operation modes. Compared with the linearized prototype, the new solution provides a holistic description of the system’s behavior with a frequency regulation over a wider range of complex actions of complicating factors. It expands the horizons of supervisory control and forecasting.

Keywords: well; ESP; second-order model; correlation; pressure losses; segments of the structure; mode states; non-linear inflow.

Based on the two-phase four-component two-dimensional mathematical model, the process of polymer impact on the oil formation is studied. To assess the possibility of oil production increase as compared to the basic case of oil displacement by water, test calculations were carried out on the displacement of oil by polymer solutions with account of various water salinity. It has been established that the final oil recovery and the dynamics of the oil recovery process substantially depend on the activity of ion exchange. In formations with a low exchange capacity, it is more efficient to use a fresh water-based polymer solution, and in formations with a high exchange capacity it is preferable to use polymer solutions based on mineralized water.

Keywords: polymer flooding; oil recovery coefficient; sorption of polymer and salt; ion exchange; characteristics of a formation.
