Explorer Historical Highlights

In 1994, while chairman and CEO of Barrett Resources, I got a call from my good friend Ray Thomasson, who said, “Bill I have a prospect Larry McPeek has worked up in the Wind River Basin that you might find interesting.” I’d worked every feature of geology in Wyoming’s Wind River Basin and was familiar with about every well drilled there during my career, so I frankly considered myself somewhat of an expert on the basin ... The Cave Gulch Prospect was located along the Owl Creek Thrust in a geologically complex area.

It is one of the most remote places on the planet and home to the largest sand desert in the world. Virtually uninhabited and underexplored, the Rub’ al Khali basin, known as “the Empty Quarter” in Arabic, covers more than a fourth of the southeastern part of the Saudi Arabian peninsula. While the area has been explored in the past, perhaps most notably by Max Steineke, the American geologist known for making the first oil discovery in Saudi Arabia in 1938, and then publicly again in the early 2000s by international oil companies, the basin appears to be of increasing interest once more.

Proposals to ban hydraulic fracturing in the United States have drawn a wide range of responses from analysts, with projected effects ranging from cataclysmic to trifling. Legislation to phase out fracturing was introduced in both the U.S. Senate and House of Representatives earlier this year. That turned up the heat on the controversy, as did the emergence of Sen. Bernie Sanders as the frontrunner for the Democratic presidential nomination. Sanders and Sen. Jeff Merkley introduced a bill titled the “Ban Fracking Act” in January.

Field Trip Organizer: Dhahran Geoscience Society Field Trip Leader: Mohammed Masrahy Date: 4 February 2021 Time: 15.30 – 17.00 (GST/GMT+4) Fee: Free of Charge Field Trip Description Over the past two decades, there have been major developments in the efforts to quantify the architectural elements, geometry, and dimensions of depositional bodies from analogues to provide quantitative input to geological models. Analogues, especially ancient outcrops and modern analogues have played a crucial role in improving the understanding of subsurface reservoir architectural elements. They provide important information on subsurface reservoir geobodies size, geometry, and potential connectivity, which all contribute to better reservoir characterization. This is especially vital for highly heterogeneous siliciclastic or carbonate reservoirs that require the integration and detailed analysis of reservoir petrophysical properties, facies, diagenesis, geometry, depositional environments and lateral and vertical variability. Robust subsurface reservoir models heavily rely on the available geological input data. Outcrop and modern analogue data from comparable systems provide additional input to geological models of the subsurface. This virtual field trip will provide valuable insights into the nature of this complexity. Aims and Objectives The virtual field trip comprises a field study of a range of continental clastic modern systems and related sedimentary facies, each of which possesses attributes that are comparable in part to the subsurface deposits. Virtual field trip attendees will gain knowledge about key competencies related to field geology, such as understanding the geomorphology of continental systems, seeing examples that explain sedimentary structures, textures, and facies, identifying depositional environments, and linking sedimentological observations to subsurface reservoir modeling. One specific aim of this virtual field trip is to emphasize that integrated reservoir characterization and modeling processes take into account actual depositional trends and distribution of the sedimentary bodies (sediment-body geometry and heterogeneity), through the understanding of modern analogues settings. Intended Learning Outcomes This virtual field trip will provide insights and offer discussions of the following aspects: An introduction to techniques and criteria for the recognition of continental (fluvial and aeolian systems), and related sedimentary facies in modern system and discussions of the application of these techniques to the study of subsurface sedimentology and geological modeling. 1D, 2D and 3D facies architecture with particular consideration of the geometry and scale of key stratal bodies that have relevance for understanding subsurface hydrocarbon reservoirs. The nature of autocyclic (intrinsic) interactions between competing sedimentary processes and consideration of the implications of these in terms of reservoir quality. The nature of allocyclic (external) controls on sedimentary processes and consideration of the effects of temporal and spatial changes in these controls on the preserved successions. The significance of accurately determining the preserved geometry of reservoir successions and performing correlations at the interwell scale. 3D prediction of the distribution of net versus non-net reservoir.

The Oman ophiolites emplacement on top of northern Oman mountains started in about the Turonian time (~90 Ma) and was concluded during the Campanian time (~80Ma). This emplacement of the Oman ophiolites was part of a regional closure of the neo-tethys ocean. Oman ophiolite displacement is estimated to have moved ~400km away from its original location below sea floor. This presentation is aimed at taking you in a virtual fieldtrip to zoom into a window in the geological history of northern Oman mountains, specifically the Oman ophiolite emplacement period. We will virtually visit different outcrops of the Oman ophiolites that tells the emplacement process story. Register Here

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

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.
