Halliburton used its January Houston Area Landmark Users Group (HALUG) meeting to unveil its new Earth Modeling solution. Charles Murphy described how a coherent model is built by integrating geoscience and engineering data in the new DecisionSpace component. Earth Modeling provides technology and workflows to build deterministic or probabilistic models at reservoir and basin scale.
The main differentiators claimed for Earth Modeling include interoperability with OpenWorks, knowledge transfer through Project Designer and easy output of a simulator-ready grid. Geovariances’ embedded geostatistics engine displays linked crossplot data including dynamic variogram modeling. Facies can be assigned from a large library of depositional environment templates and lithologies—which were well received by attendees. Landmark has dubbed these additions ‘high science simplified.’
The templates codify rules for juxtaposition of lithotypes. Proportion curves can be created by subdividing the area of the model or by grouping wells by depositional type across an interval. Lithotype curves can be copied and distributed to guide further facies modeling. The output is a simulator-ready model with fault walls that capture transmissibility.
A 3-D seismic volume can be brought in as a backdrop and geophysical attributes can be used for co-located co-kriging, but this option is not yet available to guide facies distribution. Cutoffs for parameters can be set based on multiple realizations of the final model. The release shown is available only through the Landmark partner program and is being tested by as many as six companies on R5000 version 3. Earth Modeling is due for release mid-2010.
