UBDPRO - Underbalanced Drilling Hydraulics

Managed Pressure Drilling (MPD), including Underbalanced Drilling (UBD) technology, precisely controls the annular fluid pressure profile within a wellbore, which allows drilling of what might otherwise be economically unattainable prospects. Managed pressure drilling is often performed with the primary motivation of reducing formation damage. Therefore, increasing production and aerated fluid is commonly employed in the drilling process. In hard rock applications, managed pressure drilling is often performed with the primary motivation of increasing ROP (rate of penetration). Here air/mist drilling fluids are commonly employed. UBDPRO models the complex hydraulics for compressible fluids including air, mist, foam and 2-phase fluids. The advanced software model can be used to optimize gas and liquid injection rates in order to control bottomhole pressure.FEATURES
