VIRTUAL HYDRAULICS is a proprietary integrated suite of programs to evaluate and design critical-well drilling hydraulics under simulated downhole conditions. It is most often used in the following applications.
- ECD, ESD, temperature, hole-cleaning and tripping profiles in critical wells
- Hydraulics and rheological behavior of synthetic-, oil- and water-base drilling fluids in extreme temperatures and/or pressure environments such as deepwater and HTHP drilling
VIRTUAL HYDRAULICS is a powerful multi-component tool for maximizing drilling fluid performance, minimizing overall costs. Further, it improves confidence levels while using high-performance fluids in challenging deepwater and HTHP environments. The integrated software suite uses state-of-the-art models for hydraulics, mud rheology, temperature profiles, hole-cleaning performance, and surge/swab pressures that consider the dramatic effects of pressure and temperature on downhole fluid properties.
- VIRTUAL RHEOLOGY uses an innovative “data-cube” concept to predict mud rheological properties under downhole conditions.
- VIRTUAL RDH considers the effects of downhole density and mud rheological profiles, pipe rotation, eccentricity and cuttings behavior to accurately calculate pump pressure, ECD, ESD and hole-cleaning profiles during drilling.
- TPRO uses a fully transient temperature simulator to determine the downhole temperature profile under circulating and static conditions.
- DPRO accurately determines equivalent static density profiles based on temperature, pressure and specific mud characteristics.
- TRIPPRO executes transient surge and swab analyses with effects of downhole density, rheology and time to determine optimum tripping schedules while running pipe or casing.
- CLEANPRO determines hole-cleaning profiles using fuzzy logic principles that consider the effects of rotation, eccentricity and downhole fluid properties.
