Application of Integrated Modeling in the Oil and Gas Industry

Abstract

The present stage of the oil industry development is characterized by a growing share of hard to reach reserves, the amount of complicated well stock, oil production costs and increasing requirements to production accounting accuracy, implementation of energy-efficient and resource-efficient technologies for development and production, in conditions of the multifactorial evaluation of asset development prospects a problem of the asset intellectualization is a priority. Within this problem, automation and implementation of integrated approaches to production optimization, prevention and control of difficulties, effective asset development management both on operative and long-term levels are considered. At present, a complex and effective tool in resolving the problem is an integrated model, i.e. a model of a well production process (oil, gas, water), including all production chain elements in the form of consequential component models. An integrated simulation is effectively used in operational activities of LUKOIL-PERM LLC and is an optimal tool to solve multidisciplinary tasks in field development and technology of oil and gas production, transportation and processing (using software by Petroleum Experts company). Experience of implementing the integrated simulations suggests a synergetic effect related to a need in developing associated aspects manifesting themselves by improvement of skills of the specialists, improvement of input data quality and increase of input data volume, improvement of separate component quality during their integration. A set of actions developed and substantiated using the integrated simulations and their separate components resulted in obtaining some additional oil production over 21.9 thou. t.

( 6) and (7). In order to determine the values of effective viscosities, the system of Navier-Stokes equations presented for a multiphase flow is closed using the equations of a phase-dependent turbulent model.…”

“…Oil production efficiency relies on several factors, including the operating conditions of producing wells determining the choice of surface and subsurface equipment, its operating parameters, hydrocarbon properties, etc. [6,7]. Ongoing industry trends are focused on improving oil production efficiency without replacing downhole pumping equipment or changing the existing oil gathering, transportation, and treatment system [8][9][10][11].…”
