Conditional STOP on CMM
8/12/2019 2011 What's New at CMG Event in Perth - What's New From CMG for 2011
136/162
CMOST can now support the conditional STOP situations w here onemight have a different STOP time depending on preset condit ions.For example if triggers are used to cause the STOP based on somereservoir behavior or i f the STOP is as a result of a monitor constraint.If the simulator STOPS before the final STOP keyword CMOST wi ll st illcalculate the OF values.
For HM Error and NPV, CMOST will use the t rue stop date as theobjective term stop date if the former is earlier than the latter.For Raw Simulation Resul t, CMOST wil l take the property value that isavailable at the true stop date.

Define Separate Time Periods
8/12/2019 2011 What's New at CMG Event in Perth - What's New From CMG for 2011
140/162
Break up the time periods where you have good data and create a term foreach period.Each period has to start at zero cumulative and be matched by theaccumulation for that period NOT the overall cumulative.To do this we need to Reset Cumulative for each term, then each periodis basically matched separately thus ignoring the bad period.
160
Reset Cumulative
8/12/2019 2011 What's New at CMG Event in Perth - What's New From CMG for 2011
141/162
Here the firs t t ime period had reliable data and we set up theterm Water1 for this t ime.The middle portion had unreliable data so we simply leave it outof the Terms and it will not be considered in the matching.The remaining data is reliable and we set up term Water3 forthis period as well as RESET CUMULATIVE.Hence we only history match on the good measurements andthe bad measurements do not affect the match.
