The Growth of Automation in Marine Seismic Acquisition and Processing

Andrew Long 

(Chief Scientist & Technology Analyst, PGS)

 

Oil and gas exploration is one of countless industries starting to embrace digitalization platforms, robotization, and various other forms of automation to improve the efficiency of the related processes involved in how the data are delivered. Some grandiose proposals in industry forums today include seismic processing-to-drilling workflows with timeframes of only a few days being achievable. I present several examples of how autonomous robotization is augmenting marine seismic acquisition, the use of simulation and remote control facilities for managing field operations, current bottlenecks to real time acquisition and processing, directions in AI and deep learning for seismic processing and imaging (including analogues to the minerals industry), and consider the challenges of significantly reduced human interaction to the management of future projects. This presentation is designed as a broad overview rather than presenting commercial solutions.

 

Andrew Long has a B.Sc. in physics and geophysics from Melbourne University, a PGrad.Dip.App.Physics in petroleum geophysics from Curtin University, and a Ph.D. in geophysics from the University of Western Australia. His career includes experience with land seismic acquisition and processing, satellite altimetry R&D for producing marine gravity products, and postdoctoral research in seismic imaging and crustal geophysics at Stanford University, before joining PGS in 1997. He is now Chief Scientist and Technology Analyst, with interests in most areas of seismic technology and the interpretation of geophysical data. Andrew was an SEG Honorary Lecturer for the Pacific South region in 2009; has presented various courses on seismic-related geophysics for the SEG, EAGE and ASEG; and is a member of ASEG, PESA, EAGE, SEG and SEAPEX.

Recent advances in land seismic acquisition technology

Dr Tim Dean 

 

(Research Fellow - Curtin University, Exploration Geophysics)

 

Despite a downturn in the land seismic acquisition industry the pace of technical innovation has not slowed; in just the last four years there have been ten new land seismic acquisition systems introduced.  These new systems are lighter, record data for longer, and produce higher quality data than those previously available.  Advances have not been restricted to the receiver side, with new seismic sources and positioning systems being introduced.  In this presentation I outline these recent advances and will show samples of many of the new nodes that have been introduced. 

 

Tim has an Honours degree in Geophysics from Curtin University and a PhD in Physics from the University of New South Wales.  He spent more than twelve years working for WesternGeco and Schlumberger in a variety of roles related to surface and borehole seismic acquisition including field operations, software development and research located in Saudi Arabia, England, Norway and Australia.  After leaving Schlumberger he worked as a sports technology Project Advisor at Hawk-eye innovations (a division of Sony).  He joined the Department of Exploration Geophysics at Curtin University as a Research Fellow in August 2016.

Abstract

Rock physics is an interdisciplinary branch of geophysics that explains geophysical remote sensing data, such as seismic wave velocities and electrical conductivity, in the context of mineralogy, fluid content, and environmental conditions. Thus, rock physics interpretations often require inputs from physics, geology, chemistry, chemical engineering, and other fields. For example, seismic waves travel faster in cemented rocks than in loose sediments. Since the physical behavior of rocks controls their seismic response, rock physics brings key knowledge that helps with the interpretation of rock properties such as porosity, permeability, texture, and pressure. Rock physics combines indirect geophysical data (such as seismic impedance, sonic log velocities, and laboratory measurements) with petrophysical information about porosity, fluid type, and saturation for use in reservoir characterization, evaluation, and monitoring. Typically, rock physics is used by petroleum engineers doing reservoir simulations, geologists evaluating over-pressures and making basin models, and anyone doing a monitoring survey to map fluids from 4D seismic. For all such purposes, an understanding of wave propagation is required to relate seismic properties (e.g. velocity and attenuation) to the physical properties of rocks and to evaluate seismic data in terms of subsurface petrophysical parameters.  For example, an application of rock physics is seen in 4D seismic data (i.e. repeated seismic data acquired from the same field), where fluid saturation changes are evaluated from changes in velocity using fluid substitution models. Another rock physics application is to understand and predict the effect of clay minerals on the load-bearing capacity and strength of rocks using fundamental knowledge about the properties of clay minerals (e.g. CEC, surface area, dispersability, charge, sorption, plasticity, etc.), the clay water content, as well as the effects of their distribution within the rock. Thus, an effective prediction of rock properties from indirect measurements requires a solid understanding of the physical behavior of rocks under in situ conditions of pore and confining pressures and fluid saturations.

During this one-day short course, I will provide the earth scientist and engineer with a foundation in rock physics to describe the physical processes that govern the response of rocks to the external stresses essential for reservoir characterization. The course will also offer practical guidance to help better analyze existing data. A major goal of this course is to offer practical instruction and provide working knowledge in the areas of rock physics and rock mechanics for rock characterization.

New Applications of Machine Learning to Oil & Gas Exploration and Production

Monday, July 8, 2019
TBC
TBC

2 Day EAGE course in Perth. For more information and registration, see here:

https://events.eage.org/en/2019/education-days-perth-2019/programme/bern...

Course description

The course introduction will attempt to answer the question: How will A.I. change the way we work in the Oil and Gas industry in the coming years? Looking at what is underway in other industries and guessing what type of projects are under development in R&D departments in our industry will help answer that question. Oil and Gas examples will be presented corresponding to each of the terms A.I., Machine Learning, and Deep Learning, allowing participants to reach a clear understanding on how they differ.

 

The course will then focus on Deep Learning (DL) and address all key aspects of developing and applying the technology to Oil and Gas projects. 

 - What is DL and how different is it from traditional neural networks?

 - A peek at the mathematics behind Deep Neural Networks (DNN)

 - Typical workflow to design and develop a deep learning application in an E&P project

 - Common challenges, difficulties, and pitfalls in deep learning projects

 - Software tools and hardware required + Cloud computing vs in-house solutions.

 

This will be followed by live demonstrations of two DNN-based applications specific to Oil and Gas upstream domains. 

 

First, we'll run software performing automatic fault identification will be run on released seismic data from New Zealand basins to demonstrate how a DNN recognizes faults and how it differs from other algorithms such as ant tracking. Starting from default training, the DNN can gradually learn to recognize faults like the Geophysicist or Structural Geologist. The training set constantly evolves incorporating feedback from human experts. 

 

Second, the identification of resource opportunities in very large repositories of text and image documents will be demonstrated. This will be done with a deep learning application that performs contextual search and linguistic analysis. Unlike keyword search, contextual search extracts information based on its context, just like humans do. And then linguistic analysis is run on the extracted information to identify actionable opportunities. This list of opportunities can then be further evaluated by human experts.

 

Finally, the course conclusion will summarize key learnings and answer any additional questions/queries from participants.

Course objectives

Upon completion of the course, participants will have acquired detailed knowledge of what deep learning is exactly, how it works, and in which way it differs from traditional neural networks that have been used in the industry during the last 30 years. They will understand which domains this can be applied to and for what type of applications. And they will also understand what are the main challenges, difficulties, and pitfalls when developing new applications. Finally they will have seen demonstrations of deep neural networks applied to Exploration and Production disciplines and will be able to evaluate how useful the technology could be for their own domain.

 

Participants' profile

The course is designed for geoscientists, petroleum engineers, and petrophysicists from new ventures/basin, exploration, and development & production disciplines- from early career to senior, working in oil & gas companies or service companies. 

 

Prerequisites

Participants should be familiar with at least one discipline in the Oil and Gas Exploration and Production (G&G, Petrophysics, Reservoir and Production Engineering, Petroleum Engineering)

Teena Zn Prospect - New Insights for Geophysical Discovery of Shale-hosted Zinc Deposits
Darren Hunt 
(Senior Project Geophysicist - Teck)

Teena is a Paleoproterozoic stratiform Zn-Pb deposit located 8 kilometres west of the McArthur River Zn-Pb Mine, NT.  Higher grade mineralization was drilled by Teck in 2013, and represents the most significant SHMS-style discovery in Australia since the early 1990’s.  While the style of mineralization is similar to McArthur river (HYC) Mine, Teena lies beneath 600 to 1000m of siliciclastic and calcareous sediments and is completely blind.  Thus, the system gives the explorationist  valuable insights into the challenge of exploring for blind SHMS deposits, which often present as challenging targets for geophysical detection.  This talk will present physical properties data in the context of the mineralogy and stratigraphic host and discuss the geophysical methodologies applied to at Teena and the subsequent toolkit developed for the detection of deeply buried systems using Teena datasets as examples.

Exploring the Triassic Oil Potential on the North West Shelf, Australia

Claudia Valenti (Carnarvon Petroleum)

 

The exploration history of the North West Shelf suggests that the Australian petroleum systems are predominantly gas prone, typically found beneath the mid-Cretaceous regional seal.

Carnarvon Petroleum regional and local seismic mapping, in conjunction with exploration drilling results, indicates that the Triassic has three oil prone petroleum systems, the Early, Middle and Late Triassic.

Fundamental to understanding the areas where these three petroleum systems will work is a thorough understanding of palaeogeographies, palaeoenvironments and stratigraphy. Carnarvon believes the petroleum systems have a distinct palaeogeographic distribution and are not ubiquitous source rock/reservoir horizons across the North West Shelf.

Various laboratory analysis, sedimentology, seismic mapping, seismic facies work have contributed to the identification of the most encouraging areas to explore.

Additionally, the proximity of the Triassic geology of the North West Shelf to SE Asia Triassic geology, with their similar depositional setting, prior to Gondwana break-up, adds credence to the proposed theories. Examples of the early, middle and late Triassic oil petroleum systems will be illustrated and identified in some of the major basins on the NW Shelf.

 

Groundwater Throughflow and Seawater Intrusion in High Quality Coastal Aquifers
Alex Costall (PhD Student - Curtin University)

This last year has taken me into the wonderful world of karstic aquifers, numerical groundwater flow - and solute transport - modelling. A ‘karst’ refers to terrain with distinctive structures formed from highly soluble rocks, such as limestone, dolomites, gypsums, etc. Exposure to flowing groundwater causes the rock matrix to dissolve, which can greatly affect the flow of groundwater. Caves, conduits, and fractures all present high-permeability pathways for groundwater to travel. Some of the highest quality coastal groundwater reserves around the world exist as extensive karstic aquifer systems. At coastal margins, the invisible and ever-looming seawater interface threatens fresh groundwater resources.  As the changing climate affects groundwater recharge and growing world population continues to rely on these aquifers for drinkable groundwater, the risk of contamination has implications for millions of peoples worldwide. 

Geophysical exploration methods offer unparalleled access to subsurface information, but it is not without flaws. Resistivity imaging is commonly used, but rarely with time-lapse investigation nor optimal acquisition/inversion strategy in mind. Numerical solute transport modelling has potential to aid our understanding, and define the limitations, of the both geophysical and conventional sampling methodology. Outcomes from this research aim to improve groundwater monitoring practices and numerical modelling outcomes with regard to the seawater interface. These outcomes will ultimately aid groundwater management decisions and help to preserve our fresh water resources for future generations.

Alex is a PhD student at Curtin University, Department of Exploration Geophysics, specializing in near-surface hydrogeophysical problems. He completed a Bachelor of Science (Geophysics) with first-class honours in 2014, and works part-time within the geophysics department as a research assistant and laboratory demonstrator. Alex’s research interests include groundwater and solute transport modelling, cooperative geophysical modelling, and exploration with ground penetrating radar and electrical resistivity.

Sometimes it pays to be cheap – Compressive time-lapse seismic data acquisition

Felix Herrmann (SEG Distinguished Lecturer)

During these times of sustained low oil prices, it is essential to look for new innovative ways to collect (time-lapse) seismic data at reduced costs and preferably also at reduced environmental impact. By now, there is an increasing body of corroborating evidence — whether these are simulated case studies or actual acquisitions on land and marine — that seismic acquisition based on the principles of compressive sensing delivers on this premise by removing the need to acquire replicated dense surveys. Up to ten-fold increases in acquisition efficiency have been reported by industry while there are indications that this breakthrough is only the beginning of a paradigm shift where full-azimuth time-lapse processing will become a reality. To familiarize the audience with this new technology, I will first describe the basics of compressive sensing, how it relates to missing-trace interpolation and simultaneous source acquisition, followed by how this technology is driving innovations in full-azimuth (time-lapse) acquisition, yielding high-fidelity data with a high degree of repeatability and at a fraction of the costs.
 
Felix J. Herrmann graduated from Delft University of Technology in 1992 and received in 1997 a Ph.D. in engineering physics (DELPHI Consortium) from that same institution. After research positions at Stanford University and the Massachusetts Institute of Technology (Earth Resources Laboratory), he joined the faculty of the University of British Columbia in 2002 where he is now affiliate professor. Since 2017, he is cross-appointed at the Schools of Earth & Atmospheric Sciences, Computational Science & Engineering, and Electrical & Computer Engineering of the Georgia Institute of Technology. His research program spans several areas of computational exploration seismology including economic and low-environmental impact (time-lapse) acquisition with compressive sensing, data processing, and wave-equation-based imaging and inversion. He was among the first to recognize the importance of curvelet transforms, compressive sensing, and large-scale (convex) optimization addressing problems involving simultaneously acquired/blended (time-lapse) data with surface-related multiples. He developed curvelet-based denoising and matched filtering methods that are now widely used by industry. He also made several contributions to full-waveform inversion and (least-squares) reverse-time migration by introducing concepts from stochastic and constrained optimization designed to produce high-fidelity results at lower costs. More recently, he has been involved in developing rank minimization techniques for seismic data acquisition, in the development of a domain-specific language for finite differences called Devito, and in the application of deep convolutional neural nets to seismic data processing and inversion. To drive innovations within industry, he started in 2004 SINBAD, a research consortium responsible for several major breakthroughs resulting in tangible efficiency improvements in industrial data acquisition and full-waveform inversion. At Georgia Tech, he vows to continue these activities by setting up a new research consortium with a focus on machine learning. He serves as deputy editor for Geophysical Prospecting and is a Georgia Research Alliance eminent scholar.

Our Evolving View of Time-Lapse Seismic Monitoring: 20 years of the same old Teal South data

Prof Wayne Pennington

The first ocean-bottom time-lapse seismic studies for reservoir monitoring were conducted at Teal South in the Gulf of Mexico.  The data from this field, including one legacy streamer survey and two post-production ocean-bottom surveys have been used repeatedly to demonstrate new aspects of analysis and interpretation. This seminar will walk through that history, since 1998, with examples from recent publications.

Biography

Wayne Pennington recently retired from the position of Dean of Engineering at Michigan Technological University, and is visiting Curtin University as a Senior Fulbright Scholar through May 2019.  He has spent his career in academics, industry, and (for one year) in government service, and has served as President of the American Geosciences Institute (an umbrella organization for over 50 geoscience societies) and as Vice-President of the Society of Exploration Geophysicists.
