Practical Drilling Technology OGJ SPECIAL Virtual rheology and hydraulics improve use of oil and synthetic-based muds

Mario Zamora M-I Drilling Fluids LLC Houston Two evolutionary concepts, virtual hydraulics and virtual rheology, have significantly improved the understanding and application of drilling fluid rheology and the hydraulics of oil-based and synthetic-based muds. When combined to form the core of a unitized suite of software modules, they provide new technology which is a step improvement over conventional approaches to calculate equivalent circulating densities (ECDs) and pump pressures for oil and synthetic-based muds (OBMs and SBMs). More-accurate predictions are now possible for downhole mud rheology, circulating and static densities, fri...
