Explorer President’s Column By Denise Cox

When I chose sustainable development as one of the themes when I stood for AAPG president-elect in 2016, it was to define the role of petroleum geoscience in the energy transition. This highly visible and unified message by petroleum companies underscores the importance of our industry’s role in providing accessible, affordable and reliable energy.

Optimism Pays Dividends

I keep this phrase posted on my workstation. It is a constant reminder that optimism is one of the greatest skills we can possess as petroleum geologists. Optimism toward our future, our prospects, our companies and ourselves is a key to success in our careers as professional geologists.

Explorer Director’s Corner By David Curtiss

'Going the Distance' with the World's Premier Offshore Event

While shale oil and shale gas deliver quick returns and product to markets, it’s the deepwater and other offshore discoveries that yield significant reserve additions and long-lasting production.

The Intra-Basement Reflectors in the STACK Area of Oklahoma

In Oklahoma, seismic reflection data from different areas show distinct, systematic patterns of reflectors within depth intervals dominated by the crystalline basement. It is necessary to better understand the origin and composition of these characteristic layers in the Oklahoma basement, as it will fill a major gap in the understanding of its tectonic and thermal history.

Spindletop Revisited: The Second Field

Spindletop’s glory days were gone, or so it was believed. That landmark discovery on Jan. 10, 1901 at Spindletop Hill near Beaumont, Texas had defied existing American geological thought and changed the course of history, but had faded into memory by the 1920s. But, a novel geological hypothesis would soon change all that.

Making Sense of Gas-Oil Ratio in Unconventional Reservoirs

Owing to the unique performance characteristics in unconventional reservoirs, gas/oil ratio models, which are predictive in conventional wells, may or may not be accurate in determining the success or failure of the unconventional.

Argentina's Neuquén Basin Offers 'Tremendous Growth Opportunities'

While oil production has been going strong in Argentina’s Neuquén Basin for the past 100 years, geologists with Shell and YPF say the region’s true hydrocarbon potential has yet to be discovered.

Norway's Offshore Tech Lab

“The Norwegian continental shelf may historically be described as a giant offshore technology laboratory.” That’s Jon Are Rørtveit, vice president and commercial director of the Offshore Northern Seas Foundation, talking about the unique dynamic and possibilities to be found off the Norwegian continental shelf. Norway’s offshore exploration industry is well-established as an international exporter of smart technologies and innovative solutions.

Geochemical factors controlling the phase behavior of Eagle Ford Shale petroleum fluids

Petroleum types in the Eagle Ford resource play span the range from black oil to dry gas and are produced along regional trends that are largely maturity controlled. A total of 61 shale samples covering all maturity zones were evaluated to document organic richness, organic matter type, and maturation characteristics using established geochemical parameters.

Oil families and inferred source rocks of the Woodford–Mississippian tight oil play in northcentral Oklahoma

Twenty-four oils produced from the Woodford Shale and overlying Mississippian strata in central Oklahoma were characterized geochemically to determine their possible source(s). The 168 core samples from the Woodford and Mississippian sections of 14 wells in central Oklahoma were initially characterized by total organic carbon (TOC), Rock-Eval, and vitrinite reflectance, and select samples (TOC >1.0 wt. %) were subjected to biomarker analyses to characterize source input, depositional environment, maturity, and oil-to-source rock correlations.

Buffalo Bayou K-12 Educators Hurricane Hike

Everyone in Houston lives within a few miles of a bayou. Some people think of them as permanent, but the bayous are constantly changing, especially during high water events like Hurricane Harvey. This trip is a 2.5 mile walk down a section of Buffalo Bayou where we will look at the archives of past storms and discuss what to do for future storms.
