Explorer Historical Highlights By Brent Greenhalgh

Frontier Exploration in the Rocky Mountain West

There are times when national and local forces combine in such a way that the entire hydrocarbon value chain is realized in a frontier area over the course of only a few years. Such was the case for the natural gas fields in southwestern Wyoming over the decades of the 1920s to the ‘40s.

Phase Decomposition: a Reservoir Management Tool?

Phase decomposition is an interesting technique that can decompose a composite seismic signal into different phase components, and which in turn can help with the characterization of thin target sandstone or carbonate reservoirs. Here we discuss the application of phase decomposition as a reservoir management tool, with the odd phase component (sum of plus 90 degrees and minus 90 degrees phase components) showing better correlation with the wells that control the injection and withdrawal of a natural gas storage reservoir in Denmark.

A Bond Forged in Road Trips and Geoscience

Here’s one sign of change in university- level geoscience education: This year, for the first time, both recipients of AAPG’s Grover E. Murray Memorial Distinguished Educator Award are female geology professors. Their careers have followed different paths and include contrasting professional interests, but the stories of their respective educational histories share several common links. That story starts with James Taylor. And chocolate chip cookies.

3-D Crossplotting: An Effective Visualization and Interpretation Tool

Crossplotting is widely used in AVO analysis because it facilitates the simultaneous and meaningful evaluation of two attributes. Generally, common lithology units and fluid types cluster together in AVO crossplot space, allowing identification of background lithology trends and anomalous off-trend aggregations that could be associated with hydrocarbons. Interactive crossplots allow the interpreter to visualize the relationship between different well log properties or between different seismic attributes.

Phase Decomposition and Its Applications

Phase decomposition is a novel technique that decomposes a composite seismic signal into different phase components, which can improve reservoir characterization. The technique is particularly useful in those areas where thin-bed interference causes the phase of the input seismic response to differ from the phase of the embedded wavelet in the data.

Developing Tight Oil Resources in the Middle East

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.

Gil Machado, ChronSurveys Lda & Instituto Dom Luiz Fees: €190 - Local VAT applicable Limit: 20 Participants Includes: Ground Transportation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 20 June 2023 8:30am Hotel Dom Pedro Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the field trip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

Fluid Migration and Accumulation within the Mississippian: Why 2% Oil Cut Here, 15% One Mile Away?

Water cut is a big factor in gauging the success of horizontal drilling in the Mississippi Lime Play (MLP). The contributing factors are related in part to the spectrum of producing lithofacies and reservoir quality encountered that varies laterally and vertically, sometimes dramatically.

The Bight Basin, South Australia, One of the World's Largest Unexplored Deltas. Evolution and Prospectivity; Seismic, Structure, and Balanced Sections

Presented by Kevin C. Hill, Associate Professor, University of Melbourne Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.

VG Abstract By Keith Gerdes

Tethyan Carbonates - Linking Tropical Seas and Crashing Plates to Some of the Largest Oil and Gas Fields in the World

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.

DL Abstract By Tao Sun

Integrated Reservoir Characterization and Modeling with Computational Stratigraphy

As oil and gas exploration and production occur in deeper basins and more complex geologic settings, accurate characterization and modeling of reservoirs to improve estimated ultimate recovery (EUR) prediction, optimize well placement and maximize recovery become paramount. Existing technologies for reservoir characterization and modeling have proven inadequate for delivering detailed 3D predictions of reservoir architecture, connectivity and rock quality at scales that impact subsurface flow patterns and reservoir performance. Because of the gap between the geophysical and geologic data available (seismic, well logs, cores) and the data needed to model rock heterogeneities at the reservoir scale, constraints from external analog systems are needed. Existing stratigraphic concepts and deposition models are mostly empirical and seldom provide quantitative constraints on fine-scale reservoir heterogeneity. Current reservoir modeling tools are challenged to accurately replicate complex, nonstationary, rock heterogeneity patterns that control connectivity, such as shale layers that serve as flow baffles and barriers.
