Summary of issues tabled for future versions of OPGEE, not able to be addressed for 3.0 #312

Open arbrandt opened 3 years ago

Issue #311

OPGEE does not include mass of combustion products as an output. OPGEE does not include mass of combustion air as an input. So we cannot expect mass conservation to hold for the gas species in cases where combustion gases are treated as an input stream. For example, see crude oil dewatering sheet.

Future versions of OPGEE should track these species more carefully and use atom balance to allow for rxn.

Issue #270

Uncertainty mode is quite a bit slower for some reason. When I run two fields the time to run is ~20x the time to run 1 field. Calcs seem to work, but perhaps the sampling is slow when pulling from the fugitives table? Not sure where the problem is, just putting this note here to possibly debug later.

Issue #213

OPGEE V3.0 estimates for natural gas consumed in surface processing activities appear to be low compared to reported data and EIA statistics. A report on the issue along with a supporting word document and OPGEE V3.0 model has been sent to JSRuthe (22 Mar 2020).

Issue #58 add "fraction of water lost to reservoir" in "reservoir" section of secondary input sheet with default set to 0 In the Feb 22 version of OPGEE, the preferred cell to add this input is 'secondary inputs' M89 @yuliachen

Collaborator Author yuliachen commented on Feb 22, 2019 add another stream 118 'water lost to reservoir' to 'flows out of process' on 'reservoir' sheet. Water liquid in tonne/d is "=O14/(1-'Secondary inputs'!M36)-O14". Change liquid flow into the process accordingly as the sum of two water streams out of the process

Issue #35 Most thermal projects start as cyclic then switch to steam flood after the area around the wellbore is heated. They may do a pattern at a time. This then switches to a steam flood over time. Should be included in any dynamic model of evolution of thermal EOR.
