Gas Reservoir Engineering for Geoscientists

Kamal Malick


This course will introduce geoscientists and other disciplines to conventional and unconventional gas resource reservoir engineering methodologies.


One day (eight hours)

Intended Audience

Geologists, geophysicists, petrophysicists, geo-modelers, reservoir engineers, production and operations engineers, reserves analysts, technologists, and asset managers.

Course Outline

  1. Introduce Geoscientists and other disciplines to conventional and unconventional gas resource reservoir engineering methodologies
  2. Discuss
    • The global LNG market and the United States’ position in it
    • Natural gas PVT properties, the liquids-rich behavior of gas reservoirs, and techniques to maximize liquids recovery in both conventional and unconventional reservoirs
  3. Review resource assessment techniques starting with the Volumetric method
  4. Review gas reservoir production performance, drive mechanisms, and resource assessment through engineering data
  5. Address the interdisciplinary nature of resource assessment and the collaboration required between the geoscientists and reservoir engineers
    • Pressure depletion due to infill drilling is a critical risk that must be considered while developing gas resources, especially in mature basins
  6. Calculate the drainage area and how to minimize the depletion risk in both conventional and unconventional plays
  7. Gas well deliverability and development economics will also be discussed
  8. Examples provided from major conventional and unconventional liquids-rich gas reservoirs from around the world

Learner Outcomes

  1. Perform gas-in-place calculation using Volumetric analysis
  2. Identify various types of gas reservoirs based on PVT properties and initial conditions
  3. Discuss ways to maximize liquids recovery from natural gas reservoirs
  4. Identify drive mechanism in gas reservoirs and expected recovery factor
  5. Define pressure depletion and how to minimize risk on production performance

Kamal Malick has been working in the energy industry for more than 25 years in a variety of technical and leadership roles. He has worked globally in Canada, the USA, the North Sea, and Asia-Pacific regions on various complex oil and gas fields under both natural depletion and EOR schemes.

Kamal is currently working for Calgary-based independent, Enerplus Corporation on the Williston Basin in North Dakota developing exploitation plans for the Bakken and Three Forks shale formations. He has also worked in various conventional, tight, and unconventional fields in West Central Alberta Canada. Previously, he was the Subsurface Manager for one of the largest onshore gas fields in Indonesia consisting of multiple naturally fractured stacked zones. He was responsible for managing its subsurface development and depletion planning in addition to optimizing the commercial aspects of various gas contracts on behalf of the joint-venture partners. Kamal has also worked on volatile oil and retrograde-condensate gas fields in Algeria and on several oil fields in the UK North Sea with a subsurface consultancy. Kamal started his career in Pakistan where he worked on field development and exploitation planning of oil and gas fields in the Badin Basin in Sindh and the Kirthar fold belt in Balochistan.

Kamal’s areas of expertise are reservoir engineering, field development planning, resource evaluation, and economic analysis. He has been involved with teaching and mentoring throughout his career. He conducts industry courses through the Canadian Society of Petroleum Geologists (CSPG) and the Society of Petroleum Engineers (SPE). He has given talks at various universities around the world including in Canada, Pakistan, and Indonesia. He mentors junior professionals from around the world through the SPE e-Mentoring program. He holds a Professional Engineer designation with the Association of Professional Engineers and Geoscientists of Alberta (APEGA) and is a member of its Registration Committee. Kamal holds a bachelor’s degree in mechanical engineering from NED University in Karachi, Pakistan, a master’s degree in petroleum engineering from Stanford University in the USA, and an MBA from the University of Calgary, Canada.
