About this Research Topic
Current models, experiment measures and simulation approaches cannot satisfy the requirement of developing oil and gas from deep water and deep stratum regions. The most interesting and urgent multiphase flow problems in this context can be grouped into two categories. First, unexpected crystallization of solid particle happens in multiphase flow induced by changes of temperature and pressure in the wellbore, such as gas hydrate, wax, acid gas, water scale, asphaltene, etc. Those particles can deposit along wellbore and pipe and plug the production channel of oil and gas. Second, the accompanied physical problems induced by the phase transition threaten the safety of drilling and production in deep stratum and deep-water region. For example, the phase transition changes the distribution of temperature and pressure in wellbore and increases the risk of gas kick.
It is the aim of this Research Topic to explore the challenges and open questions for multiphase flow in porous media under conditions dictated by the conditions met when developing oil and natural gas in deep water and deep stratum regions.
We will draw on contributions from several frontier engineering fields, such as gas hydrate development, CO2 storage underground, underground natural gas storage, underground coal gasification, etc. to bring the field of multiphase flow in porous media forwards.
This Research Topic will be dedicated to publishing experimental and theoretical studies related to the multiphase flow behavior in the wellbore. The Research Topic intends to cover but is not limited to the following topics:
1. Transient multiphase flow model coupling with reservoir performance.
2. THMC (thermal-hydrological-mechanical–chemical) coupling and multi-physical process in drilling and production.
3. Characteristics of heat and mass transfer process in wellbore.
4. Physical structure and dynamic deposition process of solid particles (wax, hydrate, asphaltene, scale, etc) in multiphase flow.
5. Flow assurance method and theory in wellbore.
6. Structural strength of wellbore and pipe (aspect of fluid-structure coupling).
7. New experiments and new simulation approaches towards multiphase flow in wellbore.
8. New challenges from the aspect of multiphase flow in wellbore in the frontier engineering fields, such as CO2 storage underground, underground natural gas storage, natural gas hydrate production, underground coal gasification, etc.
