  • NEW! Allan Albertson of FCRL Awarded US Patent for Cement Assisted Multilateral (CAML™) Junction and Method
    Allan Albertson, Senior Associate at Fire Creek Resources Ltd. (FCRL) was recently awarded US Patent 9,284,821 “Multilateral Well System and Method.”

    This patent pertains to an innovative method for completing multilateral wells that incorporates a cemented assisted multilateral (CAML™) junction developed by FCRL. 

    “We developed the CAML junction to address the needs of operators working in cost-sensitive reservoirs that require multilaterals to develop,” said Albertson, “with the added requirements of providing a full-drift sealed junction for both pressure integrity and a debris barrier for produced sand.”

    The method has been successfully run in two pilot wells in an international heavy oil field over a 2.5 year period. Both pilot wells were drilled with dual legs with one laterally spaced and the other stacked into a different sand. 

    “With the ability to drill further legs, our hope is to continue the pilot by adding a third leg at a time when the production systems can handle the volume,” said Albertson.

    “The primary driver is the economics,” said Albertson. “We believe the data captured over the duration of the pilot is conclusive that the CAML process is robust and capable of producing enhanced production at lower capital and operating costs.” 
    With the ability to produce two or more wells from one main bore, the observed limitation to date is the production system capacity. For more information on the CAML junction, including a case study and information sheet, please visit our CAML page.


  • FCRL presented at a national workshop on contaminated sites in April 2016
    The workshop was hosted by the Real Property Institute of Canada held April 25-27, 2016 in Montreal, Quebec. Dean Casorso along with representatives from the federal government presented: Sweet & Sour: A Unique Case Study of Orphaned Well Abandonments in the Northwest Territories. The presentation described the remediation of several sour gas wells in the Northwest Territories and the associated lessons learned.

  • Turnkey Abandonment of Wells in Hay River, Alberta for AANDC and PWGSC - Government of Canada
    FCRL successfully completed a 3 well abandonment program for the Aboriginal Affairs & Northern Development Canada (AANDC) and Public Works and Government of Canada Services (PWGCS) near the town of Hay River, Alberta. The highlights of the project, 2 wells were re-drilled in an attempt to abandon in 2011 unsuccessfully and 1 well which had the original casing, leaking 8% H2S to surface. The project included winter access construction, construction of an ice bridge, drilling out the cement set in the 2 wells re-drilled in 2011, well intervention of the well leaking H2S through killing and freeing operations, fishing out the corroded casing and placing long string casing in each of the wells. This project was a success and all 3 wells have been cut and capped reducing  the sour gas risk.  

  • Integrated Reservoir Modelling Study for a Client in Central America
    FCRL completed an Integrated Reservoir Modelling Study for one of our clients. FCRL worked closely with the client to analyze the geological and geophysical data, production history, well test summaries and the seismic data to create a static and dynamic reservoir model. This process provided an increased understanding of the resource / reserves potential for the field thereby extending the development area and potential reserves by more than 50%. FCRL was able to provide council on well placement and well design to economically appraise and develop the field where vertical wells were uneconomic. The highlight of this project for FCRL and our client was to be able to combine our petroleum engineering expertise with our operational expertise and the client’s local knowledge to take the project through the full cycle. 
  • Deep Ultra-HPHT Well
    FCRL, in conjunction with one of our partners, has been involved with designing, modelling and creating a drilling and completion program for a 6500m (21,300ft) sour HPHT well with temperatures of up to 230C (450F) on the east coast of India. The process has been a combination of multiple disciplines to provide a robust casing / completion design while optimizing costs. We have been guiding the entire procurement process to ensure all contracted services and materials are suited for the challenges that come with drilling and testing HPHT wells. FCRL will also provide operations support throughout the drilling and completion activities to ensure wells are delivered safely as designed and within approved budget / timelines.
