Well Integrity solution

WellScan's Well Integrity solution starts with the casing design module, which enables user to select and specify the number of casing strings required to complete the well. The appropriate selection of casing prevents collapse of the borehole during drilling as well as hydraulically isolating the wellbore fluids from the subsurface formations and formation fluids. It calculates casing and tubing loads and stresses to compare with design safety factors. Also, you can check casing ratings with design loads applying minimum API standard and perform advanced thermal simulation to determine circulating temperatures.

 

Using our casing wear directional drilling module, you are able to determine the effect of various RIH and rotating operations on the overall integrity of the well.

 

The Casing Deformation and Standoff directional drilling module is used to determine the resulting standoff of a casing with a proposed centralisation program.

Main Features of Well Integrity solutions

  1. Casing design - Casing selection through Tri-Axial analysis for every load case; Hydraulic and Temperature models: Wellhead growth and packer forces simulations

  2. Casing deformation Stand-off - Casing Stand-Off 3D profile using stiff-string model; Calculation of cased-hole tortuosity for improved RIH liner/completion Torque & Drag analysis

  3. Casing Wear - Calculation of 3D Casing Wear using stiff-string T & D, and advanced wear model; Wear Factor (WF) calibration - use your own WF calibration database or the state of the art published WF values. Calibrate your results against caliper logs. Calculation of residual burst, collapse and tensile strength

Benefits of Well Integrity solutions

  1. Design Flaws and Well Life - Detect potential well architecture design flaws and design strings to be safe and economic over the life of the well. Account for realistic well tortuosity and casing wear in complex wells.

  2. Economic - Determine economic and safe well head and packer solutions.

  3. Contact Forces - Determine contact forces of drill pipe’s tooljoint and body along the entire string using advanced soft and stiff string models.

  4. Runs and Operations - Determine the cumulative effect of successive runs and diverse operations such as Rotating Off Bottom, drilling, reaming, milling, etc…

  5. Enhanced RIH completion analysis - Determine the potential as cemented casing string standoff prior to perforating the production string.

  6. Torque & Drag & Buckling analysis accuracy enhancement - Using an advanced Torque & Drag & Buckling model, determine the 3D deflection of the casing string in the borehole.

  7. Well positioning improvement - Accurately determine the position and deformation of all casing strings, as cemented.

  8. Enhanced stand-off calculation - Using an advanced casing centralisers modeling, a cross section representation of casing position in the borehole is determined, along measured depth.

  9. Cement sheet barrier qualification - Determine if the proposed centraliser placement will provide an adequate cement barrier.
