Fracture modeling has become a vital part of successful drilling, completion, and ongoing stimulation of shale plays, as well as other unconventionals. It is also important in optimizing recovery in mature fields. Welcome to an interview with Ahmed Ouenes, CEO and Founder of FracGeo.
There are a surprising number of AAPG Members (new and experienced) who are not familiar with the technical divisions of AAPG and what they do. Given how much excellent work is done in the divisions, everyone is encouraged to learn more about them.
Basins around the world hold identified potential for unconventional resource development and a combination of exploration, assessment and evaluation seems certain to uncover other favorable plays.
AAPG’s Energy Minerals Division is excited to present a strong and informative technical program at the 2016 AAPG Annual Convention and Exhibition in Calgary, Canada. EMD has an intriguing program this year, covering a variety of unconventional energy topics of current interest to both EMD and AAPG members.
The shale boom has propelled the United States oil and gas industry to a leading position, not just in production, but also in navigating the perilous waters of public opinion.
While exploration has slowed in many parts of the world in response to the industry’s lagging downturn, India is moving full steam ahead to encourage exploration and production on a domestic and international scale.
Marita Bradshaw, an AAPG member and retired geologist with Geoscience Australia, has spent her career helping to uncover Australia’s oil and gas potential and is now pleased to see recent large discoveries on the continent and the expansion of the export LNG industry. A symposium will be held in her honor this month at the AAPG-SEG International Convention and Exhibition (ICE) in Melbourne.
In the coming year, the Energy Minerals Division is looking to improve and expand its information delivery system. EMD also is seeking volunteers to fill a number of vacant section and region councilor positions.
AAPG offers two short courses in conjunction with this year’s Unconventional Resources Technology Conference (URTeC). A wealth of information in a short period of time, theses short courses are an effective and efficient way to learn about the industry.
This year, URTeC has added an enhanced preview of “Coming Attractions.” In addition to looking at established plays, URTeC will provide significant information about emerging unconventional resource possibilities in North America and around the world.
Recognition and Correlation of the Eagle Ford, Austin Formations in South Texas can be enhanced with High Resolution Biostratigraphy, fossil abundance peaks and Maximum Flooding Surfaces correlated to Upper Cretaceous sequence stratigraphic cycle chart after Gradstein, 2010.
The Eagle Ford Shale in South Texas is one of the more exciting shale plays in the United States at the current time.
This e-symposium will focus on how surface geochemical surveys and Downhole Geochemical Imaging technologies can be utilized jointly to directly characterize the composition of hydrocarbons vertically through the prospect section.
This e-symposium covers advances in geothermal energy, integration with petroleum operations, and lessons learned in recent cases.
The geochemistry of formation fluids (water and hydrocarbon gases) in the Uinta Basin, Utah, is evaluated at the regional scale based on fluid sampling and compilation of past records.
The gas transport in organic-rich shales involves different length-scales, from organic and inorganic pores to macro- and macrofractures. In order to upscale the fluid transport from nanoscale (flow through nanopores) to larger scales (to micro- and macrofractures), multicontinuum methodology is planned to be used.
The Mississippian-Devonian Bakken Petroleum System of the Williston Basin is characterized by low-porosity and permeability reservoirs, organic-rich source rocks, and regional hydrocarbon charge.
Upon successful completion of this course, you will be able to describe faults and fractures in carbonates, black shales, and coarser clastics as they occur in the northern Appalachian Basin.
This course is ideal for individuals involved in Midland Basin exploration and development. Successful development of Wolfcamp shale oil relies on complex inter-relationships (ultimately interdependencies) within and between a wide variety of scientific disciplines, financial entities, and company partnerships.
This presentation will look at well placement vertically in the pay, well azimuth and well trajectory with explanations of how geology and post-depositional effects can make the difference between a successful well and a failure.
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.
