Explorer Historical Highlights

How many exploration teams make four huge discoveries in four years? This is the story of one such team from ARCO Indonesia Inc.’s new ventures department. As described in last month’s installment of Historical Highlights,” Resilient: Part I,” the Wiriagar Deep-1 exploration wildcat successfully tested natural gas in 1994, flowing a combined 30 million cubic feet per day from three stratigraphic intervals on ARII’s onshore Wiriagar production sharing contract

Tangguh is the liquefied natural gas production and export hub for multiple gas fields discovered during the 1990s in eastern Indonesia by Atlantic Richfield Indonesia Inc., a subsidiary of ARCO. The name “Tangguh,” meaning “resilient” in Bahasa Indonesian, was chosen by Indonesia’s then-President Suharto in late 1997. Tangguh turned out to be far more enduring than Suharto’s reign, as 2024 marks the 30th anniversary of ARII’s drill and test of the discovery well, Wiriagar Deep-1.

Three potent forces are buffeting the offshore energy industry in 2024. Thanks to technology, it’s meeting those challenges head on. Offshore operators today face significant demands to reduce or at least contain higher costs and increase efficiency, especially in production operations. At the same time, the industry’s need to build up long-term reserves has pushed offshore exploration toward more remote, frontier prospects. In sports terms, offshore exploration and production companies are like teams struggling with spending caps while also trying to boost their scoring ability.

Production and prospects continue to pour out of the greater Permian Basin-area of West Texas. One growing play echoes the very beginning of the U.S. shale revolution. More than 20 years ago, development of the Barnett Shale in the Fort Worth Basin introduced the world to the practice of combining hydraulic fracturing with horizontal drilling. That became a history-making shale gas play. Today, operators are targeting the Barnett more than 300 miles to the west, in the Midland Basin, where the formation is deeper and oilier.

This has been an exciting decade for lunar exploration, but it hasn’t been without its setbacks. NASA officials announced a revised schedule for the Artemis lunar program. The subsequent missions are expected to be delayed by approximately one year each, reflecting the extensive work required before astronauts can undertake lunar missions in the latter part of this decade.

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.

Salt welds form due to salt thinning by mechanical (e.g., salt-flow) and/or chemical (e.g., salt-dissolution) processes. This webinar explores how we use 3-D seismic reflection, borehole, and biostratigraphic data to constrain the thickness and composition of salt welds, and to test the predictions of analytical models for salt welding.

The “Great Crew Change” has become the “Competence Train Wreck” due to the repeated personal mis-management practices of our industry and again not anticipating the known volatility of commodity prices. Despite this, hydrocarbon based energy will continue to comprise over 60% of the world’s energy mix for at least the next half century and of that energy need over half of it has yet to be found! Personal experience in working for National Oil Companies, Parastatals, large independent oil companies, small independents, as an independent and as a consultant have given me the perspective of some of the best and some of the worst of the exploration practices the industry has to offer.

DL Abstract

Subsurface risk and uncertainty are recognized as very important considerations in petroleum geoscience. And even when volume estimates are relatively accurate, the reservoir characteristics that determine well placement and performance can remain highly uncertain. In analyzing results and work practices, three aspects of uncertainty are reviewed here.

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.

President Biden has laid out a bold and ambitious goal of achieving net-zero carbon emissions in the United States by 2050.  The pathway to that target includes cutting total greenhouse gas emissions in half by 2030 and eliminating them entirely from the nation’s electricity sector by 2035. The Office of Fossil Energy and Carbon Management will play an important role in the transition to net-zero carbon emissions by reducing the environmental impacts of fossil energy production and use – and helping decarbonize other hard-to abate sectors.

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

VG Abstract

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.

Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments.

DL Abstract

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.
