SPE NL YP invites you to a lecture on September 25th:
Geological realism of deep water
channel reservoir models with intelligent priors
Simon Rojas (Xodus Group)
Following a publication in this month’s
issue of the SPE Journal of Petroleum Technology (JPT), the presenter of this
SPE YP lecture will show the outcomes of his study which was conducted in
collaboration with Heriot-Watt University.
In this work the authors propose to tackle
the problem of preserving realism in automated history matching by building
robust prior models that describe the non-linear multivariate dependencies
between geological parameters of the deep water channelized system. The
researchers built multi-dimensional realistic priors using intelligent
techniques, specifically One-Class Support Vector Machine. OC-SVM allows
capturing hidden relations of the deep water channel parameters (Channel Width
and Thickness, Meander Amplitude, and Wavelength). Furthermore, it is possible
to predict realistic parameter combinations, not observed in the available
data; but still plausible in nature.
In automated history matching we sample
from these realistic priors in order to assure geological realism. A Multiple
Point Statistics (MPS) algorithm SNESIM is used to model facies in a deep water
channelized reservoir. History-matched models produced under geological
realistic constraints reduce uncertainty of the production prediction.
Has a BSc. In Geological Engineering from
Universidad Central de Venezuela, an MPhil. in Sedimentology from the
University of Reading, a PhD. In Petroleum Engineering from Heriot-Watt
(Edinburgh) and has been working in the industry (Apache Corp, PDVSA, Xodus
Group) for 14 years.
