Necessity may be the mother of invention. But sometimes it’s just all the mosquitos. Leila Donn, a doctoral student at the University of Texas at Austin studying environmental geoscience, wasn’t necessarily looking for a computer model to help her find the location of ancient Mayan caves last year. Mostly, she just was hot and tired and the work was going slowly.

When new technology enters the oil and gas scene, talk of layoffs can creep into water-cooler conversations. Will better software and computers replace people, or will they push the industry forward, creating the need for additional staff? These questions are especially pertinent for geophysicists today, as artificial intelligence and machine learning technologies are processing and interpreting seismic data at record speeds, often delivering results that rival, if not surpass, that of humans. With some software companies calling their platforms a “seismic revolution” by offering real-time data interpretation, geophysicists might question how they will fit into this new, seemingly supersonic world.

Workshop
Salzburg, Austria
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.

Field Seminar
Abu Dhabi, UAE
Thursday, 30 January 2020, 8:00 a.m.–3:00 p.m.

Date: January 30th, 2020 Time: 8am – 3pm Start/Return Point: Abu Dhabi Equipment Required: Sturdy boots/shoes, sun protection (hat, sunglasses, sun-cream, etc.). Fitness: Most places require light walking (100s meters / comparatively flat). Sabkha outcrop will involve some wading in ankle-deep water/mud. Field Trip Leaders: Hesham Shebl, Ibrahim Al Ali and Hani El Sahn Price: $85 – excluding 5% VAT Register now The modern carbonate-evaporite depositional environments along the Abu Dhabi shoreline and offshore Abu Dhabi belong to the few areas of the world where the geoscientist can observe the interplay between carbonate and evaporite sedimentation. The analysis of modern analogs is one of the few means by which high-resolution spatial complexity of stratigraphic systems can be described. If the horizontal dimensions of facies belts are less than the typical well spacing, modern analogs, together with seismic and production data help to construct realistic geologic and simulation models of subsurface reservoirs. Supratidal (sabkha) to intertidal (microbial mat), and lowermost intertidal to shallow subtidal (lagoon: skeletal-peloid tidal-flat) environments will be studied along the Abu Dhabi coastline in the vicinity of Al-Qanatir Island. Al-Qanatir Island: In the vicinity of the road to Al-Qanatir Island participants will be able to study a complete and undisturbed lateral facies succession of the upper supratidal to the shallow subtidal environments: Upper supratidal stranded beach ridges Topographic highs, some cm above the adjacent upper sabkha environment Upper sabkha (upper supratidal) Surface covered by polygonally-cracked halite crust Middle sabkha (middle supratidal) Surface covered by finely-crystalline, whitish anhydrite polygons Lower sabkha (lower supratidal) Surface covered by shiny, sparkling gypsum crystals Upper to lower intertidal microbial mat Crenulated or crinkled microbial mat above gypsum mush facies Blistered and pinnacle microbial mat Polygonal and tufted microbial mat Lowermost intertidal to shallow subtidal. Peloid-skeletal tidal-flat. This trip provides an insight into recent to modern evaporitic coastal depositional systems, that can be considered analogues to parts of the Mesozoic reservoir systems of the Middle East (e.g. intra-Arab & Hith anhydrites). Itinerary 8:00 am Depart for Sabkha outcrops at Al-Qanatir 9:00 am Arrive at Al-Qanatir Island 9:15 am Introduction Stop 1: Lateral Sabkha Sequence Stop 1a: Upper, Middle, and Lower Supratidal Sabkha Environment Stop 1b: Upper, Middle and Lower Intertidal Microbial Mat Environment Stop 1c: Lowermost Intertidal to Shallow Subtidal Peloid-Skeletal Tidal-Flat Environment Lunch 2:00 pm Depart Sabkha for Abu Dhabi Register now

Date: January 30th, 2020 Time: 8:00 am – 3:00 pm Start/Return Point: Abu Dhabi Equipment Required: • We cannot stress enough the importance of good sturdy field boots. If you are buying new boots, spend a few days “breaking in” the boots before coming to field. • Good solid hiking or work boots (leather) (no long heels for field work) &bull: Clothing for both hot and cold weather • Personal hygiene items. • Rain gear (waterproof, breathable) (in case) Field Trip Leaders: Dr. Abdelwahab Noufal and Ismail Al Hosani Price: $300 – excluding 5% VAT Register now The one day field trip to Jabal Hafit is tailored to offer participants the opportunity to study the structural style and fracturing of carbonate rocks analogous to reservoir units of the globally important UAE oil province. The clear exposure of these carbonate rocks in this tectonically complicated area provides a significant opportunity to study and explain the structural style and deformation history of the region, with emphasis to study fractures pattern and fracturing mechanism with relation to the paleostress and in‐situ stresses, and the link to fractures hydraulic conductivity. The proposed locations to be visited on this fieldtrip will demonstrate the stratigraphic relationship of the various rock units and their fracture systems that have been developed during long geological deformation. There are significant similarities between these exposed rocks and those units seen in the Abu Dhabi oil fields by means of depositional characteristics and fracture system and fracture related diagenesis (cementation/host rock alteration) with its impact on sealing potential. List of the observation stops made over Jabal Hafit with their GPS record, lithology and structures: Register now

VG Abstract

This lecture will discuss the differences between carbonates and siliciclastics from their chemical composition through their distributions in time and space. Building on these fundamental differences, we will explore the challenges carbonates pose to petroleum geologists in terms of seismic interpretation, reservoir quality prediction, field development, etc. Peppered with humorous personal stories, still raging academic debates, and the heartfelt frustrations of real industry professionals, the aim is to inspire students and young professionals to rise to the occasion and embrace the reservoir rocks that petroleum geologists love to hate.

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.
