Practical Applied Geostatistics with Petrel

This course will develop knowledge and understanding of the role played by uncertainty in geomodeling and provide a framework for optimum decision making using Petrel. It covers the statistical and geostatistical tools available for understanding and quantifying uncertainty and the considerations required when using them for reservoir characterization and model building.

Petrel will be used as the primary tool for investigating the complexities of uncertainty in geomodeling. This allows us to understand how best to use the cutting-edge geostatistical features of Petrel to construct geomodels which accurately reflect our level of confidence in data at each stage of the exploration and production.

    Day 1

    Uncertainty in Data

    - How uncertainty arises

    - Modelling and quantifying uncertainty

    - Why geostatistics differs from statistics

    - How geostatistics describes uncertainty

    - Separating what we know from what we do not know

    - Distinguishing between uncertainty and measurement

     

    Participants will learn to appreciate the origins of uncertainty and how simple geological concepts can combine to create apparently intractable problems. Then, we see how accurate analysis can impose order again and, paradoxically, we can learn to predict the unpredictable. Through simple examples and simulations we will see that this requires us to make clear distinctions between what we know and what we do not know, and between what we have seen or measured and what we have not yet seen.

     

    Day 2

    Uncertainty in Prediction

    - Variability in one measurement affecting accuracy in prediction of another

    - Variance within a single data set

    - Placing bounds on what we don’t know

    - Using these bounds to make better predictions

    - Using these bounds to quantify uncertainty in predictions

    Simple tools – histograms, bivariate regression – are re-visited from the perspective of uncertainty, and we see how much more useful information is contained in even the everyday tools with which we are already familiar. Then we look at the specific geostatistical tools, starting with variograms, and see how these make the relationship explicit between known and unknown.

    Day 3

    Geomodels

    - The role of geomodelling

    - Modelling the predictable and modelling the unpredictable

    - The history of geomodelling tools and the search for balance between different interpretations of ‘best’ predictions

     

    Looking at the entire history of geostatistics, through Petrel, we see how the search for better characterization of uncertainty has driven the development of new tools. We look at cases in which each tool may be considered to give the best prediction. Understanding why each tool has been developed, and under which circumstances each is best, allows us to choose the most appropriate tool for each task.

    Day 4

    Using Large and Complex Data Sets

    - Multivariate analysis

    - Log suites and seismic attributes

    The need for better input to geomodelling has resulted in developments in seismic attributes and log interpretation which rely heavily on statistical and geostatistical tools . We look at these developments and try to understand their limitations, then see how statistical and geostatistical tools can place quantified limits on their accuracy and applicability.

    Day 5

    Monte Carlo Modelling and Production Statistics

    - How Monte Carlo methods work

    - Finding the best inputs to a Monte Carlo simulation

    - Optimizing simulations with limited data or limited time

    - Monte Carlo analysis

    We see how Monte Carlo methods work using simple Excel examples before using Petrel to demonstrate how Monte Carlo analysis combines with geostatistics to give insights unimaginable 20 years ago. Finally, the power of Petrel for geomodeling is combined with the understanding of uncertainty developed during the week to create statistics which embody the state of the art in understanding the relationship between geology and geomodeling.

    Goa

    Goa a state in India's West region, is a former Portuguese colony with rich history. It is 3,700 square km in size with a population of approximately 1.4 million. Goa has a unique mix of native and Portuguese cultures and architecture that attracts an estimated 2.5 million visitors each year (including about 400,000 foreign tourists). Panaji, Goa's state capital is also known as Panjim, Ponnje or Pangim. It is one of the most charming cities in India. It is visibly different from the rest of India, owing to Portuguese rule which isolated it from the rest of India for 451 years.

    Goa is a hub of tourism in India. From the 1960s, Goa has been attracting a steady flow of visitors - first the hippies and returning expat Goans, then the charter tourists visiting (starting with the Germans in 1987), pilgrims visiting Catholic and Hindu shrines, those opting to settle in Goa as their home, visitors coming here for medical treatment, and a growing number of those who attend seminars and conferences in Goa. It is also world famous for its beaches, its ancient temples and churches, and its Goan carnival.

    There are a number of museums. There's the Goa State Museum and then there's Architect Gerard da Cunha's relatively-new architectural museum called Houses of Goa. The Xavier Centre of Historical Research, at Porvorim, has its Gallery on Christian Art, named the Xavier Xandev Museum. the archaeological museum and portrait gallery is at Old Goa, the Christian Art Museum at the same location (a little further away at the Santa Monica Convent annexe), and the Pilar Seminary Museum. Big Foot at Loutolim (aka Ancestral Goa) is an attempt to illustrate and recreate Goa's traditional past. There's even a vintage-cars collection of sorts - Ashvek Vintage World "dedicated to restore and preserve motoring and motorcycling gems of historical interest in Goa".

    Goa has one airport at Dabolim in Vasco. Some airlines fly directly to Goa, but most international flights arrive via Mumbai. Many domestic airlines have daily flights to and from Bangalore, Delhi, Hyderabad, Mumbai, Pune, Chennai, Jaipur, Ahmedabad, Kozhikode (Calicut). Domestic Airlines flying into Goa include Kingfisher airlines, spicejet, Jet Airways, Indian Airlines, Air Deccan, Indigo, GoAir, Paramount Airways and MDLR Airways. Air India has international flights to Kuwait and UAE twice a week. Air Arabia has discount flights to Sharjah, UAE Qatar airlines has flights to Doha, and has convenient connections to Western Europe, Africa and USA.
