1 Shell Exploration and Production The Algebraic Oil Project by Hennie Poulisse review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project Perspectives

2 Copyright: Shell Exploration & Production Ltd. review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project Perspectives in E&P problems this – tacit - assumption is virtually always violated is virtually always violated allow parameters to be elements of a Ring 1. the simplest, useful setting for E&P problems is a Polynomial Ring parameters ( = ‘interactions’) inherent part of problem “If you try and take a cat apart to see how it works, the first thing you have on your hands is a non-working cat”. [Douglas Adams, The Hitchhiker’s Guide to the Galaxy, 1979] (personal) conclusion from ‘ THE ROAD TO REALITY, A COMPLETE GUIDE TO THE LAWS OF THE UNIVERSE’ by sr. Roger Penrose: There is only one universal physical law: “There is NO universal physical law “. 2. no a priori model (physical, regression, black-box,..) available simulations are meaningless SCALE 3. local  global = algebra  geometry generators shape change in shape

3 Copyright: Shell Exploration & Production Ltd. review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project Perspectives multi-zone well, consisting of two zones A and B input measured data: pressures, temperatures, productions, valve positions production-geological data problem: interactions in this system during commingled production business incentive: improve balance production versus watering – or gassing out this is not available !

4 Copyright: Shell Exploration & Production Ltd. review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project Perspectives some start-up blah-blah: there is the model ! if the data would be exact => calculate Ideal of Points with BUCHBERGER-MÖLLER (BM) algorithm in the real-life case (noisy data): ABM calculates the generators = ‘approximate relations’

5 Copyright: Shell Exploration & Production Ltd. review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project PerspectivescABMABM data model patent has been submitted Q what IS a contribution?? impossible to describe in terms of separate zone productions what is the contribution from the zones to the total production way out: relate ‘states’ of multi-zone system to down-hole valve positions (ICV valves) to down-hole valve positions (ICV valves)

11 Copyright: Shell Exploration & Production Ltd. review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project Perspectivesc production polynomial with respect to this basis

13 Copyright: Shell Exploration & Production Ltd. review meeting 13/02/ Project Principles Real-world Example Technology Transfer and – Deployment Project Perspectivesc sealing of both geological seal and of the packer confirmed sealing of both geological seal and of the packer confirmed differences in annulus pressures do not lead to ‘good’ relations differences in annulus pressures do not lead to ‘good’ relations ABM clusters the data points in a number of points ABM clusters the data points in a number of points conjecture: these are the ‘states’ of the system conjecture: these are the ‘states’ of the system testing not all combinations => not all states are covered => ambiguity can be represented testing not all combinations => not all states are covered => ambiguity can be represented production allocation has to be reconsidered completely production allocation has to be reconsidered completely the result is new the result is new it could not be computed before it could not be computed before
