To gauge accuracy, model parameterization used 5,805 experimental data points from a wellвЂ“established data set, along with a second data set comprising 13,440 data points extracted from the OLGAвЂ“S library (Schlumberger 2017b). Our work attempts to extend the current DF model such that it is numerically robust, accurate, and applicable to all well inclinations. The existing DF model that meets these requirements is only fully posed from 2В° (from the horizontal) to upward vertical.

or 2 in., вЂњthe difference can be on the scale of millions of dollars in capital investment,вЂќ he said.Implementation of a driftвЂ“flux (DF) multiphaseвЂ“flow model within a fully coupled wellbore/reservoir simulator is nontrivial because it must adhere to a number of strict requirements to ensure numerical robustness and convergence. вЂњSo yes, you had a safe design but you did not have one that in todayвЂ™s world would be economic,вЂќ he said, explaining that, вЂњif it is overdesigned, then essentially money has been wasted on equipment that is more than what is necessary.вЂќ If an operator can reduce the diameter of a subsea pipeline by just 1 in.

That meant using larger than needed processing equipment and pipelines to compensate for what they did not know about the behavior of the multiphase flow. In lieu of a complete understanding of multiphase flow, Mack Shippen, a product champion for one of SchlumbergerвЂ™s top multiphase modeling programs, said early offshore explorers were forced to make conservative design decisions when building a production platform. вЂњWhen the industry first moved offshore, they were afraid to go with multiphase flow pipelines because they did not know what was happening inside of them, or what kind of facilities they would have to have at the outlet end in order to handle the fluctuating rivals of gas and liquid.вЂќ вЂњWhat we have done is to make it possible for the industry to live with the complex multiphase flow problems that face them on a daily basis,вЂќ said James Brill, a multiphase flow expert who recently retired as a research professor of petroleum engineering at the University of Tulsa. More than anything else, this advancement is what has allowed offshore operators to extend their reach beyond the shallow-water fields and into those thousands of feet deep. Armed with these tools, engineers and scientists had the measurements they needed to marry computational science and fluid dynamics. Over the years, the industry invented devices that could accurately calculate flow rates, velocities, and volume fractions, along with downhole temperatures and pressures. Back then, an engineerвЂ™s ability to predict flow behavior was strictly limited to what could be observed at the wellhead.

In the 1960s, when the industry began studying how to model multiphase flow, which is the science of how liquid and gas interact inside wellbores and pipelines, little was known about the complex physics involved.

While working to fine-tune its offshore capabilities, developers are also busy expanding the technologyвЂ™s application areas to include shale field development, hydrate remediation, and heavy oil extraction. Without it, nearly all subsea wells would be too costly or dangerous to develop. In the realm of enabling technologies, multiphase flow modeling has proven to be one of the most important to the oil and gas industry.
