Seismic

A short course designed to introduce E&P staff to the key concepts, principles and applications of quantitative seismic interpretation tools (Amplitude analysis, AVO, Attributes, Inversion, Depth imaging ) that can add value in projects for exploration, field appraisal or reservoir management.

AAPG and ABGP invite you to participate in an interactive, multidisciplinary workshop featuring presentations and discussions exploring opportunities to improve companies’ efficiency and effectiveness throughout the E&P cycle, from block acquisition and exploration to development and production.

This three-day workshop builds on the success of the first AAPG Carbonate Reservoirs of the Middle East GTW, held in Abu Dhabi, UAE in 2015. It is dedicated to addressing the hydrocarbon bearing carbonate reservoirs of the Middle East, in the context of a changing oil market within a more challenging exploration and development environment. These challenges include the shift from traditional anticlinal traps to stratigraphic traps, and development strategies for dealing with maturing, long-producing, giant fields.

The main objective of this field trip is 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. Although the carbonate rocks exposed in Jebal Hafit area are of Early Eocene–Miocene age (Rus, Dammam and Asmari Formations), the emphasis here is to study fractures pattern and fracturing mechanism with relation to the paleostress and the link to fractures conductivity.

The selected stops will demonstrate the stratigraphic relationship of the 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 reservoir characteristics and fracture system and fracture related diagenesis (cementation/host rock alteration) with its impact on sealing potential.

Jebal Hafit, an elongated asymmetrical, double‐plunging, NNW‐SSW trending anticline with an elevation reaches up to ~ 1140 m high, is situated at the border between Oman and UAE. It extends ca 30 km in the direction NNW–SSE with average width of 4 to 5 km.

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.

Supratidal (sabkha) to intertidal and shallow subtidal (microbial mat and peloid-skeletal tidal-flat) environments will be studied 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 from the upper supratidal to the lower intertidal and shallow subtidal:

• 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 sub-tidal
• Peloid-skeletal tidal-flat

Many of these depositional environments and facies successions correspond to those observed in cores from the subsurface of the Arabian Peninsula.

An overview of a new ambient seismic imaging method and applications of the method throughout the lifecycles (exploration through refracing) of unconventional oil and/or gas fields.

There are more approximately 1,000 oil and gas fields in the world that have been classified as "giant," containing more than 500 million barrels of recoverable oil and /or 3 trillion cubic feet of gas.

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.

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.

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.

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

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.

This e-symposium presentation places the interpretation of deep-water turbidites discernible in 3-D seismic inversion data within a geological context.

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 entire Middle Pennsylvanian–to–top Precambrian basement (500 m) interval was cored in early 2011 in the BEREXCO Wellington KGS #1-32 well in Wellington Field, Sumner County, KS.

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.

This presentation is designed for exploration/production geologists and geological managers or reservoir engineers.

The presentation will focus on hydraulic fracture geometry in shales, the materials used in the fracturing process, and treatment monitoring via microseismic.

This presentation will show where there are cases of missing sections, but none of them can be attributed to normal faulting.

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 presentation will focus on the seismic stratigraphic and seismic geomorphologic expression of deep-water deposits, including both reservoir and non-reservoir facies.

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.

This course can help you gain the ability to describe the complex and highly variable reservoirs, which are typified by complex internal heterogeneity.

Gas hydrates, ice-like substances composed of water and gas molecules (methane, ethane, propane, etc.), occur in permafrost areas and in deep water marine environments.

As commodity prices have dropped, many shale plays have become uneconomical as statistical plays and have increasingly become recognized as geological plays demanding new insights from data.
