Enhancing Petroleum Field Profitability Via Optimisation of Production and Injection Operations

An oil and gas field requires careful operational planning and management via production optimization for increased recovery and long-term project profitability. With inevitably high environmental and financial stakes associated with the exploration and production of mature oil and gas fields, there is a strong incentive to enhance hydrocarbon recovery and production via systematic and mathematical-oriented approaches. In further response to this challenge, the application of sophisticated simulation methodologies to integratedly capture the reservoir behavior, multiphase flows (in wellbores and flowlines), and gas–oil–water separation in the processing facilities is constantly increasing. Liquid loading in gas wells and artificial lift design considerations, reservoir pressure maintenance via water injection, gas–water coning during production from vertical and horizontal wells, pressure drop, and liquid holdup of multiphase mixtures in highly deviated flowlines are some of the specific complexities associated with this system. The effects of these constraints span several timescales over the entire time horizon.
