Mapping of seismic and lithological facies is a very complex process, especially in regions with low seismic resolution caused by extensive salt layers, even when only an exploratory view of the distribution of the reservoir facies is required. The aim of this study was to apply multi-attribute analysis using an unsupervised classification algorithm to map the carbonate facies of an exploratory presalt area located in the Outer high region of the Santos Basin.
When one lives in Louisiana, even in the northern part, February and early March are full of tidings of “laissez les bon temps rouler!” or “let the good times roll!’’ Only geoscience nerds like you and I would apply that to May’s exceptional 2019 AAPG Annual Convention and Exhibition in San Antonio. So, start these good times rolling now by registering early on or before March 21 for a great discount.
On the surface, the employment outlook for geoscientists in oil and gas looks wonderful. The projected job-growth percentage for geologists remains in double digits, reduced slightly by softer oil prices. That’s still better than most other occupations and impressive for a well-paying profession. But petroleum geologists don’t make their living on the surface. Drill deeper and some mitigating trends become apparent.
Marches. Protests. Sanctions. Power struggles. Thanks to 24-hour broadcasting and social media, news of Venezuela’s political and economic crisis has reached the four corners of the Earth. But how does South America’s petroleum powerhouse affect the geoscientists living within its borders? What goes on in workplaces and classrooms far away from cameras? The EXPLORER talked with students, professors and professionals to find out how the crisis is affecting them.
We analyze western Caribbean structural styles and depositional controls associated with Late Cretaceous–Cenozoic deformational events using a 1600-km (994-mi)-long, regional, northwest–southeast transect extending from the Cayman Trough in Honduras to northern Colombia.
What are your resolutions for the new year? I have two suggestions. First, get involved and stay involved with the AAPG. Second, seek certification from the AAPG Division of Professional Affairs. You will not regret keeping these resolutions. It is an investment in your career.
The Energy Minerals Division celebrated its 25th Anniversary in 2002. The Division emphasized to the AAPG membership that it was AAPG’s center of activity on energy minerals and unconventional energy resources. EMD originally focused primarily on coal, uranium, geothermal energy, oil shales and tar sands. However, its focus expanded and in 2002, EMD’s most active unconventional resource areas were coalbed methane, gas hydrates, and unconventional energy economics.
Where are the best opportunities in the future for exploration investment? The central question about where to look, where to drill, which area of the world holds the greatest promise, in terms of profits, the rule going forward may very well be: “When you go low, you go high.”
With OPEC increasingly overshadowed by Saudi Arabia and Russia’s cooperation, and the United States’ escalating production, who holds the power in the global oil arena?
Mountains and beaches. Colonial cities, farming communities, indigenous villages. Central Eastern Mexico is full of diverse cultures and landscapes. It is also home to the Tampico-Misantla super basin, a 25,000-square-kilometer area that has produced oil since 1869.
Memoir 97– Far from being isotropic and homogenous, as once naively envisioned, shale reservoirs are complexly layered accumulations of fine-grained sediment. Geologic variation on scales ranging from that of stratal architecture to that of lamination within individual beds must be understood in order to locate and exploit areas of high production within shale reservoirs. Shale reservoirs remain largely geologic plays – not merely lease plays or strictly engineering plays made possible by improvements in drilling and completion technology. Release date: 08/2012
Memoir 98 – This memoir comprises works on biostratigraphy, ichnology, stratigraphy, depositional facies, diagenesis, and petroleum and mineral resources of the Great American Carbonate Bank. Release date: 01/2013
Memoir 94 – Thrust fault-related folds form numerous important hydrocarbon traps in sub-aerial and deep-water fold and thrust belts as well as in inversion fold and thrust belts. This memoir presents 16 papers on new advances in the analysis and understanding of thrust-related fold systems including detachment folds, thrust-fault propagation folds, wedge thrust-related fold systems, and basement-involved fold systems. Release date: 10/2011
This volume will prove useful to anyone interested in the methods for observing and quantifying the pore systems that control hydrocarbon storage and flow in unconventional reservoirs.
This volume includes contributions dealing with the origin of the magnetic minerals, and the application of MS as a palaeoenvironmental or palaeoclimatic proxy and also as a tool to provide astronomical calibration in order to improve the chronology of selected time intervals.
Continental margins and their fossilized analogues are important repositories of natural resources. With increased availability of high quality geological, seismic and potential field data, imaging of these margins and their embedded sedimentary basins and magnetic rocks has reached new levels of refinement and definition, as illustrated by the examples described in this volume.
Comprised of 48 chapters, this Memoir covers the biostratigraphy, ichnology, stratigraphy, depositional facies, diagenesis, and petroleum and mineral resources of the GACB. Product #787. Price: Member $184/List $304.
