Oil and Gas Engineering Expertise

Production Engineering Advisor consulting for several E&P companies, providing technical support and design to the evaluation of alternatives and the implementation of optimal artificial lift solutions for the Duvernay deep over-pressured reservoir in Alberta and the Montney liquids rich play in NE British Columbia.

David Sask Technology has been providing consulting services to both Oil & Gas Producers as well as Oil and Gas Service Providers since 2001.

 

Contracts have been from multi-year to daily contracts on a wide variety of project types.

Actively involved in both major WCSB liquids rich reservoirs (Montney and Duvernay).

  • Responsible for production issues and worked with completions, operations and facilities. 

  • Led team to implement wet metering technology in liquids rich gas wells with LGR ratios from 50-250 bbls/mmscf and reduced CAPEX by $45million. 

  • Evaluated artificial lift options and established an artificial lift plans.

  • Utilized well bore modelling software (OLGA) to simulate artificial lift technologies and their economic impact on field development.

  • Optimization Lead in field with 1100 horizontal gas wells. 

  • Developed review processes to evaluate well performance, economics, LOE and identify workover and optimization candidates. 

  • Installed pilot projects to evaluate artificial lift techniques with on-site support.

 

Artificial lift has been the primary focus of work and investigations since 2005. This work has been focused on artificial lift in horizontal gas and liquid rich gas fields.

  • Plunger lift testing, software development to increase plunger efficiency (CIPC 2008-160, SPE 137860)

  • Gas lift (Montney)

  • Jet pumps (Duvernay, Montney)

  • Chemical foam lift including capillary tube

  • Velocity strings

  • Rod pumps

  • Worked closely with service providers to develop new methods

  • Steering committee for two industry consortiums

Artificial Lift

I have been involved in the design of down hole equipment in numerous capacities throughout most of my career. This includes both conceptual design to meet a need, as well as detailed design and manufacturing drawings. 

This includes:

  • Drill stem testing equipment (electronically controlled real time systems)

  • Dewaxing control valves

  • Coiled tubing delivered equipment

  • Velocity string recovery system

  • Subsea test systems for offshore wells

  • Subsea isolation valves

  • Artificial lift equipment

  • Geothermal heat recovery systems

 

The Government of Canada provides tax incentives to encourage Canadian companies to conduct scientific research and experimental development (SR&ED). These tax incentives come in three forms: an income tax deduction, an investment tax credit (ITC), and, in certain circumstances, a refund. 

Technology development in the oil and gas industry can usually take advantage of the provisions of the SR&ED tax credit program to lower the overall cost of projects. It is crucial to design the project plan and document it appropriately in order take advantage of the SR&ED funding that is available.

I have extensive experience over the past 30 years in preparing the documentation to plan, execute and file claims for this CRA plan.

Horizontal wells have been the focus for work during the last 15 years of my career.

A key contributor to industry understanding of fluid flow and artificial lift in horizontal wells. The use of production and video logging were early methods that helped identify key impairments to production. 

 

SPE 149477 details how well bore modelling (OLGA) has been used to test the performance impact from tubing landing depth and well bore trajectory in horizontal wells.

I have instructed the Horizontal Well Course for the Artificial Lift R&D Council since the inception of the course in 2012.
