Well Integrity

C-FER Technologies is pleased to announce the release of a new version of Well Xplore Software.

New features of Well Xplore v1.4 include:

  • Import wells, logs, and pads into new and existing Well Xplore files;
  • Nominal ID and OD are now overlain on the cross-section view;
  • Quickly delete a log – no more simultaneous loading while deleting; and
  • Improved SQL database compatibility
    • Solved crash issues when sharing files between systems with different versions of SQL Server

Since the development of the first torque and drag models used to predict rig hook loads in the early 1980s, drilling and completion engineers have relied on various forms of proprietary and commercial software to:

  • optimize well trajectory and tubular designs;
  • prevent buckling and lockup; and
  • understand the installation load profiles for critical string components.

Longer laterals, advanced completion tools, and complex well trajectories demand a more flexible and rigorous torque and drag...

Abstract

Horizontal wells have been widely used to significantly increase reservoir exposure in a wide range of conventional and unconventional oil and gas recovery applications, including tight-rock and multi-stage fracturing, offshore, primary and thermal heavy oil projects. In the heavy oil and bitumen reservoirs of the Western Canadian basin, horizontal wells have been extensively employed in Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS) in-situ recovery projects....

Course Overview:

This hands-on course will provide attendees with an overview of wellbore tubular deformation modes. Various wellbore applications (enhanced recovery, thermal, CHOPS and cavern storage) will be reviewed, along with an overview of some of the deformation mechanisms (permafrost thaw, salt creep and formation movement) and impacts on well integrity. Emphasis will be on the use of C-FER’s Multifinger Caliper (“MFC”) analysis software (Well Xplore™) to identify and characterize such...

Course Overview:

This course will provide attendees with an overview of the considerations, key factors, industry guidelines and practices, examples, and field experience related to the design and integrity of thermal recovery wells.

The objective of this course is to review the:

  • Thermal well design process, industry regulations and recommended practices (IRPs);
  • Key material properties and damage mechanisms of casing and liner tubular steels, wellbore cements, and formations;
  • Casing and liner...

Background

The Challenge

The percentage of oil and gas fields being developed with high curvature and horizontal wellbores continues to increase throughout the industry, and the ability to effectively and economically produce these wells is becoming increasingly important.  Horizontal and other directional wells are found in various applications, including unconventional oil, condensate and gas wells which are often developed using pad-drilled horizontal wells onshore, and platform-drilled...

Industry Challenge

In Alberta, wells designated for abandonment must be tested to determine if there is any flow of gas through the surface casing vent. Flow rates of more than one bubble in 10 minutes must be repaired prior to abandonment.

The test must be repeated following the repair and abandonment operations to confirm that there is no gas leak prior to cutting and capping the well. 

It is difficult to measure these low flow rates of gas accurately as even small amounts of back pressure on...

The Industry Challenge:

Geothermal energy is a proven “green” energy technology in areas of the world where high temperature hydrothermal sources are close to the earth’s surface, such as Iceland, New Zealand and California. 

These resources, however, are scarce and rarely located near centres of major power consumption, limiting their impact on the global power generation need. Some attempts have been made to develop Enhanced Geothermal where there are no natural high temperature sources near...

The Industry Challenge:

Evidence that might explain the root cause of a failure event during well servicing is frequently destroyed by the structural damage, fire or explosion that results from the failure, making it difficult to reconstruct the operating conditions leading up to the event.

Eye witness accounts can also be unreliable as individuals usually only observed a small component of the events, lacking an overall view of the entire incident.

How We Help:

C-FER uses our knowledge of well...
