.... Major outcomes are the work-flow description of RTVFM: virtual metering work flow, real-time production calculation, and implementation in the digital oilfield (DOF) framework (Fig. 1). The complete paper discusses the methodology in detail. The paper presents three RTVFM case studies in offshore oil...

... in the complete paper. As real-time data were acquired, it became apparent that the data could also be used in real time to help quantify actual downhole pressures. New calculations were designed for simpler visualization of equivalent circulating densities (ECDs) at the shoe, bit, and weak zones in the well...
