Assessing the Integrity of Wellbores and Seals

 

NRAP models for seal integrity are used to predict the potential for fluids to flow out of the storage reservoir based on the evolution of the pressure and saturation.  Models are being developed for flow through wellbores and faults/fractures, as well as porous flow through the seal.

 

NRAP is utilizing and adapting several research codes for the simulation of fluid flow out of the reservoir.  For wellbore flow, NRAP has developed detailed process models for flow in both open wells (using LBNL’s T2Well-ECO2N) and cemented wells (using LANL’s FEHM).  For fracture/fault flow, NRAP has developed detailed process models based on LLNL’s NUFT-C.  All of these models are research tools, but the underlying simulators are available.

 

NRAP has used these detailed models to develop a suite of ROMs for predicting flow out of a reservoir.  The ROMs were generated through the use of LLNL’s PSUADE, which used the process models to develop response surfaces.

 

These ROMs have been incorporated into the CO2-PENS system platform for integrated assessment modeling.
