Amplitude variation with offset or angle has been widely used for discriminating hydrocarbons from brine-saturated rocks. Such analyses are based on Zoeppritz equations that describe the partitioning of energy at a rock interface into reflected and refracted energy components. These equations are complicated and, to get an intuitive understanding of their capabilities and limitations, various investigators and researchers have provided approximations by adopting some simplifying assumptions.

It is a well proven fact that a diverse workforce is good for business and improves the bottom line – but the E&P industry, in common with many others, is not making significant progress in this area. A recent report on gender diversity in the energy industry, for example, found that, at 22 percent, oil and gas has one of the lowest shares of female employees of any major industry – an imbalance that transcends seniority, geography and business segment.

While artificial intelligence and data-driven innovation seem to be making significant strides in many industries over the past few decades, specifically in areas of workflow automation and helping to reveal hidden insights from various data, there is a widespread sense within the industry that its pace in oil and gas is not progressing as rapidly.

On the surface, the employment outlook for geoscientists in oil and gas looks wonderful. The projected job-growth percentage for geologists remains in double digits, reduced slightly by softer oil prices. That’s still better than most other occupations and impressive for a well-paying profession. But petroleum geologists don’t make their living on the surface. Drill deeper and some mitigating trends become apparent.

Matching talent with short-term projects, and giving geoscientists the tools they need to successfully complete the projects is the perfect solution for quickly changing times.  It’s also a perfect solution when the pool of highly specialized technical experts is dispersed throughout the world.  To solve those twin problems and to bring together projects and people, Petrocubic developed an easy-to-use platform, Petrocubic (http://www.petrocubic.com).  Welcome to an interview with Vitaly Meyer, founder of Petrocubic. Petrocubic is growing quickly and will be featured in AAPG’s U-Pitch program at ACE, May 19 - 22. https://ace.aapg.org/2019/networking-and-events/u-pitch and at URTeC, July 22-24.

Wednesday, 7 October Thursday, 8 October 2020, 8:00 a.m.–5:00 p.m.

Join us in Salzburg, the “castle of salt” and cradle of Mozart and Doppler, for a meeting aimed at bringing together different perspectives in the science of evaporite basins: from their formation to their deformation, from description and characterization to modelling. Exploratory success in evaporite-rich basins worldwide has depended on the role of evaporites as a deformable substrate, as a seal, or even as a good thermal conductor. The aim of this workshop is to improve our understanding and predictive ability by addressing evaporite systems in an integrated manner, all the way from precipitation to structuration, and exploring the multiple properties of evaporite sequences. The pre- and post-meeting field trips will also explore the salt mining heritage of the region, first exploited by the Celts 3500 years ago, and the salt-related structures of the Northern Calcareous Alps.

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.

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.
