The field trip will lead to the Sunub/Ansab area to discuss the postobductional extensional, NW-striking Frontal Range Fault which formed in the course of gravitational collapse of the Saih Hatat and Jabal Akhdar domes. The fault is marked by the occurrence of listwaenite. The vertical displacement amounts to a few to several kilometers. Shearing ensued in two intervals, during the late Cretaceous to early Eocene and probably Oligocene. At this fault segment, the first stage is characterized by extension. The second stage is marked by dextral motion, including local transtension. The listwaenite dispalys the unusual feature of a ductile shear zone which trends obliquely to the Frontal Range Fault.

At the hot spring of Hammam Al Ali the Frontal Range Fault is superbly exposed. The presence of the hot spring may well be related to the fault’s transtensional releasing bend as well as the occurrence of a nearby basalt which intruded the Paleocene-Eocene Jafnayn Formation.

Gravitational collapse also created contractional structures due to E-W compression. Near Jafnayn, a wide open syncline in Eocene formations will be shown whose axis trends N-S, and on the SQU campus a syndepositional, E-dipping Miocene thrust formed within the Barzamen Formation. It displays ramps and an intervening flat. In Al-Khod Village, pillow basalt was pressed over a mudflow deposit along a west-dipping reverse fault. The two compressive faults could have formed coeval conjugate faults. Compression is related to convergence of downthrown hanging wall blocks.

The AAPG Latin America & Caribbean Region and the Colombian Association of Petroleum Geologists and Geophysicists (ACGGP) invite you join us for GTW Colombia 2020, a specialized workshop bringing leading scientists and industry practitioners to share best practices, exchange ideas and explore opportunities for future collaboration.

The 2-day workshop brings together technical experts and industry leaders from Colombia and throughout the Americas to take a multidisciplinary look at future opportunities for exploration and development of Southern Caribbean Frontier Basins.

Cross disciplinary workflows play an important part of successful characterization of shale reservoirs. This course discusses how the artificial kerogen maturity of organic-rich Green River shale affects the petrophysical, micro-structural, geochemical and elastic properties.

Recognition and Correlation of the Eagle Ford, Austin Formations in South Texas can be enhanced with High Resolution Biostratigraphy, fossil abundance peaks and Maximum Flooding Surfaces correlated to Upper Cretaceous sequence stratigraphic cycle chart after Gradstein, 2010.

Unger Field, discovered in1955, has produced 8.6 million barrels of oil from a thinly (several ft) bedded, locally cherty dolomite containing vuggy and intercrystalline porosity.

This e-symposium presents techniques for predicting pore pressure in seals by examining case studies from the Gulf of Mexico and incorporating the relationship between rocks, fluids, stress, and pressure.

Effective hydraulic fracture stimulation is critical for shale development, and microseismic is the only technology able to map the growth of these hydraulic fracture networks.

This presentation describes a proven workflow that uses a standard narrow azimuth 3D seismic, conventional logs, image logs and core data to build five key reservoir properties required for an optimal development of shale plays.

This study will focus in the combination of λρ – μρ inversion with clustering analysis techniques in order to discriminate brittle zones in the Barnett Shale.

Projects in several shales will be discussed, including Marcellus, Eagle Ford, Haynesville, Fayetteville, Montney, and Barnett, as will several seismically-detectable drivers for success including lithofacies, stress, pre-existing fractures, and pore pressure.

The Eagle Ford Shale in South Texas is one of the more exciting shale plays in the United States at the current time.

This presentation will look at well placement vertically in the pay, well azimuth and well trajectory with explanations of how geology and post-depositional effects can make the difference between a successful well and a failure.

This e-symposium provides highlights of the hydraulic fracturing mechanics, analysis, and design, and is derived from a two and one-half (2-1/2) day course which is designed for drilling, completion, production engineers, engineering technicians, geologists, well-site and completion supervisors, and managers, who desire to possess a comprehensive and integral knowledge of Hydraulic Fracturing.

This e-symposium will provide information on which tools, processes, and procedures all geoscientists, engineers, and technical professionals working in shale plays need to understand and implement.

The Mississippian-Devonian Bakken Petroleum System of the Williston Basin is characterized by low-porosity and permeability reservoirs, organic-rich source rocks, and regional hydrocarbon charge.

This e-symposium covers how to conduct an interdisciplinary evaluation of mature fields to determine the best approach to recover remaining reserves.

Upon successful completion of this course, you will be able to describe geomechanics in shale reservoirs and discuss differences between plays.

Upon successful completion of this course, you will be able to describe faults and fractures in carbonates, black shales, and coarser clastics as they occur in the northern Appalachian Basin.

The presentation describes a well established fracture modeling workflow that uses a standard 3D seismic, conventional logs, image logs and data from one core to build predictive 3D fracture models that are validated with blind wells.

This esymposium takes a close look at workflows associated with resource plays, and analyzes where integration must occur between disciplines, data, and workflows at all phases of the process.
