TubeFlow PIC for Production Enhancement

Hydraulics

Models production, injection, and circulation of fluids in the well including effects of heat transfer to/from the formation. In addition, matrix treatment operations such as acidizing and chemical sand consolidation treatments can be modeled

Production System Analysis

Models inflow control device (ICD) flow- estimates ICD pressure loss. Coiled tubing velocity string design can also be performed

Fracturing

Supports conventional and multi-stage fracturing operations. Computes perforation pressure loss, bottomhole treating pressure, and fracture geometry

Production Enhancement Software Suite

The software suite for production enhancements in TubeFlow PIC is used to model production and injection operations. These operations may or may not include well intervention such as matrix treatments, artificial lift, acidizing, fracturing, well unloading, and production system analysis.


Hydraulics

  • 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 in injection

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 weight and overpull while run-in-hole (RIH) or pull-out-of-hole (POOH)
  • models extended reach by determining minimum tractor pull requirements

Tubing Movement

  • 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
