Cost-Effective Technologies for Onshore Well Abandonment and Verification

Recorded On: 06/22/2021

Industry stakeholders, including operators and regulators, are seeking pragmatic approaches to more efficiently and cost effectively implement decommissioning and verification programs. Proven and new technologies are capable of ensuring effective permanent sealing. However, some of the emerging technologies may only be cost effective in offshore and Arctic situations, where there is easy access to multiple, closely spaced wellheads with a service spread that includes support services and crew accommodation at minimal incremental costs. For onshore operations, these new technologies need to be cost-effective when deployed at scale. Unrealistic expectations run the risk of not only unnecessarily driving-up P&A costs, but also the magnitude of the orphaned well inventory.  

In this webinar, we will briefly review the containment challenges and issues in terms of how many cows worth of methane a small seepage might represent. The primary focus of the webinar will be the available and emerging technologies currently being applied or tested in the field. We will touch on the challenges that may be posed in terms of cost and/or potential limitations with respect to external leakage paths. We will briefly review the lab and field-testing procedures for assessing promising breakthrough technologies and how results might be better shared with the various stakeholders in other regions.

The event format will spur interaction and exchange: Jonathan and Matteo will present some opening remarks, before being challenged by an expert panel of abandonment practitioners. The entire team will then attempt to address questions from the audience during the final 30 minutes.

This webinar is categorized under the Production and Operations and Projects, Facilities, and Construction technical disciplines.

Jonathan Heseltine

Senior Researcher, InnoTech Alberta

Jonathan Heseltine is a Senior Researcher with InnoTech Alberta.  In his 18 years in the energy industry, he has overseen a range of engineering and laboratory projects related to wellbore integrity. This work includes testing of alternate barrier materials, logging technologies, leak measurement systems, and casing connections.  He has a background in technology development and data analysis, including development of a risk-based well integrity assessment tool, sand control failure database, and a study correlating drilling and cementing practices to cement log response.  Other projects examined casing deformation in high load applications in steam injection wells, salt cavern storage and permafrost wells.  Jonathan holds a master’s in degree mechanical engineering from the University of Saskatchewan and is a registered professional engineer in Alberta.  He is an avid outdoorsman and enjoys hiking, sailing, and backcountry skiing in his free time.

Lawrence Jonker

Well Abandonment, Site Decommissioning and Reclamation Specialist, Remedy Energy Services Inc.

Lawrence is an experienced Technical Specialist with over 22 years of history working in Alberta’s oil and gas energy sector. During this time, he has gained experience in various sectors, including innovation and new technology, directional drilling, well integrity, enhanced oil recovery processes, facilities and production, end of life cycle facility decommissioning, abandonments and site reclamation.  Lawrence has supported Directive rewrites to the many rules and regulations that govern these activities within the province of Alberta and has been involved with developing industry best practices in Insitu/heavy oil operations.  His more recent experience includes a position with the Alberta Energy Regulator’s (AER) Field Surveillance and Operations Branch as a Heavy Oil Technical Specialist where he led a team of InSitu/Heavy Oil field Inspectors and was involved with the development of AER’s new Integrated Decision Approach OneStop platform and the development of over 400 business and operational assessment rules. Lawrence then transitioned into a Senior Advisory role with the AER’s Technology and Innovation Team where he provided technical reviews and proof of concept involving the evaluation, testing and compliance verification of various new technologies, prior to commercialization and industry acceptance. Lawrence has built highly credible relationships with industry partners and is skilled in providing guidance to oil companies to ensure compliance is maintained throughout the operational lifecycle, including reporting and self-disclosing operational upsets.  Lawrence currently works at Remedy Energy Services as a well abandonment, site decommissioning and reclamation specialist.

Matteo Loizzo

Matteo Loizzo has been an international consultant in well integrity and CO2 storage for 12 years. His previous career with Schlumberger spanned field operations, research & development, QHSE and carbon dioxide geological storage (CCUS). His current research interests include harnessing creeping formations (such as salt and shales) to help control well leaks, modeling leaks through cement, inverting geophysical measurements and quantifying methane emissions from oil & gas wells. He also provides technical training in the field of CCUS, plug & abandonment, well integrity, management systems, and process safety.

Matteo holds an Master’s degree in aerospace engineering from Rome university “La Sapienza”, Italy, has authored or coauthored 31 technical papers as well as a book chapter on CO2 storage, and he’s the Program Chair of the SPE Well Integrity Technical Section.


Garry Randal

Field Supervisor and Engineering Software Developer

After graduation from high school with honors at a younger than normal age Garry decided to work in the oilfield to earn tuition to College.  Starting work in the pumping service line with BJ Services and Halliburton.  From there he moved into Drilling Fluids Engineering and developed several computer programs to assist wellsite personnel handle the basic functions of Fluid Hydraulics, Well Control, Cementing and Directional Drilling .  Continuing his career he moved into the position of Wellsite Drilling Supervisor in a contract role where he garnered experience drilling deep foothills wells and ultralong Slant wells where world records were set.  Following that in 1994 he moved over to the well service , completions and production operations as a wellsite supervisor.  Garry joined Remedy Energy Services In 2002 and shortly thereafter was asked to come into the corporate office as a superintendent for servicing and abandonments where he stayed until 2018 and then returned to the field as a SME in well abandonments.  He is currently active in the field as a supervisor and continues to develop significant engineering software solutions for the industry.
