Hydraulics

• models production, injection, and circulation of fluids in the well including effects of heat transfer to/from the formation 
• supports a wide spectrum of wellbore fluids ranging from single phase fluids such as air and brines to more complex multiphase fluid system (e.g. foams)
• multiphase flow modeling includes both empirical and mechanistic models
• supports injection of steam and sluries
• designs insulation/packer fluids for deep water environments with flow assurance problems
• supports real-time modeling

Production System Analysis

• designs coiled tubing velocity strings to prevent liquid loading in wells 
• aids in fluid determines inflow/outflow well performance using appropriate reservoir and multiphase flow models
• aids in selection of appropriate tubing size
• models inflow control device (ICD) flow- estimates ICD pressure loss

Fracturing

Torque and Drag

• considers three types of well intervention: coiled tubing, capillary string, and wireline
• evaluates forces and stress on coiled tubing, capillary string, and wireline during well intervention
• determines the buckling status of intervening tubing in the well and identifies lock-up/compression depth
• estimates the fluid drag on tool during well intervention
• calculates the set down wieght and overpull while run-in-hole (RIH) or pull-out-of-hole (POOH)
• models extended reach by determining minimum tractor pull requirements

• predicts the length and force changes in tubing due to piston, buckling, ballooning, and temperature effects 
• determines the maximum triaxial tubing stress and aids in material selection for feild operating conditions
• considers effects of slackoff/pickup in tubing forces calculations
• includes fluid flow and formation heat transfer effects
• determines packer-to-tubing force and designs length of seals required

Well Unloading

• supports both capillary string and coiled tubing         
• finds an optimum depth at which the intervening tubing (coiled tubing or capillary string) must be placed for an effective well unloading operation
• determines the minimum pump flow rate (N₂ or foam) to unload the well
• estimates the pressures in the well utilizing appropriate multiphase flow models during the unload process
