To contact ExplAnalysis:
ExplAnalysis, Inc., develops, markets, and maintains software designed to manage the exploration Risk Analysis process. The software is fully probabilistic and is presented in the form of Excel® spreadsheets. To use the software, it is necessary to purchase either Oracle’s Crystal Ball® or Palisades’s @Risk® software—for pricing and other information, visit
While a basic understanding of Monte Carlo simulations in general and @RISK® or Crystal Ball® in particular is desirable, the manuals provided with the software (ours, ot theirs) make the user functional in probabilistic Risk Analysis in a matter of minutes. In addition, the software contains a wealth of embedded help.
Software modules are available for the following analyses:
1) Prospect Analysis - discrete oil or gas case.
2) Prospect Analysis - mixed oil/gas case.
3) Concession/play analyses the ‘flagship’ of the software
4) Rollup of a portfolio of prospects - what is your
expectation for volumes found, and number of
discoveries made, for your exploration program?
5) Multizone prospect rollup (models chance relationships
and decision behavior) - 2 and 3 zones.
6) Oil/gas recovery tool (based upon reservoir conditions
and oil/gas compostion).
7) Amplitude-related prospect risk analysis (with
8) Lognormal plotting template. Plot up to 1000 data
points on a log-probit scale, determine whether
your sample is lognormal, and review summary
9) Play ranking tool. Rank a portfolio of opportunities
based upon a combination of strategic, fiscal,
and/or technical parameters, weighting their
importance to match your company’s strategy and
10) NEW!! (Unconventional Gas Volumetric Tool).
Calculate ‘tank volume’ (GIIP), technically and
commercially recoveble volumes, and per-well
yield (range in average recovery) from inputs
capturing uncertainty in area/thickness, depth,
PVT and reservoir characteristics. Example
11) NEW!! (Unconventional Gas Well Aggregator).
Most stochastic volumetric estimators available on the market are fundamentally flawed in that on each iteration, the same ‘parent’ EUR distribution is sampled - this implies perfect knowledge of future results. Using the method developed by Brown and Haskett, the user models an ‘uncertainty envelope’ for per/well recoveries, which is aggregated to geologic and commecial volumes. Example
Prices for this software suite are competitive, and include support. Licenses are sold by office/site, structured to the size of the organization. Contact EAI for evaluation versions of the software.
