VelPAK’s Wizard module enables you to automatically create a workflow from its interface. This facilitates the re-running of models and the use of non-standard functions, as well as generating a full audit trail of your technical steps. The software operates with full transparency of your depth conversion process with ‘no black boxes’. You can compute 1000+ depth models at the click of a button to reduce your depth uncertainty, whilst enhancing your productivity and the efficacy of your team.
Stochastic Modelling within VelPAK is achieved through using the comprehensive Workflow system looping through depth conversion with a range of values and storing and applying the data within the Analyze module. The Analyze Module then allows filtering and analysis of the results and gives confidence as to the likely range of uncertainty in the model, and the deterministic parameters which will yield credible P50 (most likely) and end-point (P10, P90) solutions.
Setting up a depth conversion that would give a “Base Case model” (M0) that would produce the best technical case, the VelPAK workflow system then loops to run and re-run the depth conversion perturbing the Constraints to produce multiple depth realizations. Constraints and ranges for the multiple realizations are set up either before the model is run or during the first run of the workflow itself.
Typically, at least 500 models will be run and statistics and volumes for each well, for each layer and for each volume will be stored in the form of easily analyzed Data Grids. Data can also be output to Excel. The statistics, volumes and parameters for each realization are recorded.
The animation option of the Analyze module will capture snapshots as required so a ‘cartoon’ can be run to watch the range of reservoir size or any other displays of interest. All the parameters of each model are saved such that any particular realization can be re-created by calling up the model number as required.
