Explorer Director’s Corner

During the height of the pandemic, Society of Exploration Geophysicists Executive Director Jim White and I discussed how we could work better together – delivering an innovative conference for petroleum and energy geoscientists that also involved other geoscience disciplines focused on solving real world challenges. Our elected leaders at the time supported the vision for AAPG and SEG to create a new, joint annual meeting: the International Meeting for Applied Geoscience and Energy, or “IMAGE,” conducted in cooperation with SEPM. We’re eager and ready for IMAGE ’22 in Houston at the end of this month, and hope that you are, too.

People familiar with the energy business know that most existing vertical wells produce little oil or gas. They might be surprised how many horizontal wells fall into the same category. Under the right circumstances, this growing number of wells in decline could represent an investment opportunity. Or, it might become a giant abandonment headache for the oil industry.

When the International Petroleum Technology Conference comes to Saudi Arabia in February, the technical program will include a significant look at both unconventional oil and gas and conventional tight oil in the Middle East. Those are two different concepts in the region and the distinctions are important. The Middle East holds a large conventional tight oil resource, now emerging as a serious focus for development. With so much recent attention devoted to unconventional resources, conventional tight oil could be considered an overlooked sibling.

Worldwide oil and gas exploration results took a major hit from reduced investment and the ongoing COVID pandemic last year. Cautious industry spending and overall selectivity over prospects likely reduced discoveries to their lowest annual level in 75 years. Here’s the recommendation from one industry analyst for 2022’s global exploration and supply outlook: Stay chill for now.

Listening to “A Change Is Gonna Come” as I write prompted me to think about change. For some of us, change is not a comfortable thought because we focus on how change affects our sense of self, or we fixate on the potential loss of comfortable routines and familiar circumstances. For others, change is the stuff of life because it promises something new and exciting. For AAPG, change is inevitable as we prepare to serve future generations of petroleum geologists and geoscientists in closely related fields like environmental geology, geothermal energy and the burgeoning hydrogen industry.

Unconventional resource development has a remarkable history, combining breakthroughs and advances in both technology and geoscience. The pace of progress might have slowed in recent years, but that history is still being written.

What motivates you? How do you keep going? I have been thinking about how we have been keeping motivated over the past year while most of us have been coping with working from home, juggling office space and taking care of children, along with job losses, health crises, and few (if any) interactions or in-person networking opportunities. I know that many of you have been experiencing all or some of those situations and, unfortunately, it is not over yet!

If you have ever wondered what Robert Southey, who wrote “Goldilocks,” Lewis Carroll, who wrote “Alice in Wonderland,” and W.H. Adams, widely credited with discovering the Permian Basin, have in common – and you would be forgiven if you haven’t – then this month’s AAPG Global Super Basins Leadership Conference will be the occasion to find out. Because someone from Chevron has been thinking about that very comparison – both from the perspective of how the company is working to use the Permian as a template for future exploration and also because it sums up the state of affairs in 2020 about as well as anything.

Super basin applications and analogs continue to drive the future. As we learn more about them, we discover how valuable super basins are to exploration and development. As a result, AAPG continues its initiative to showcase some of the world’s greatest petroleum basins with the fourth Global Super Basins Leadership Conference.

In a world that has seen rock-bottom oil prices, a sharp decline in energy demand, constrained funding for oil and gas and a worldwide COVID-19 pandemic, the future for unconventional resources looks – Challenging. Although, not too bad. That might seem counter-intuitive, but many analysts say the outlook for unconventionals remains positive even as the oil industry goes through a period of struggle and woe.

VG Abstract

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.
