Error: Unknown keyword

[DanatKMGE]

Good day! There is an error on start: Unknown keyword. But the file runs on Eclipse, and all is OK. Everything is set correctly, as in manual (OPM FLOW VERSION: 2021-10, MANUAL REVISION: Rev-0).

Here is what it outputs:

Error: Unknown keyword: SURFCAPD

Thank you so much for the report. The direct cause of this diagnostic is a programming error in OPM's keyword representation for SURFCAPD. We've erroneously recorded the JSON file as providing the SURFADS keyword instead. We'll fix this in the development sources, but that fix won't be in an official release until the 2022.04 version later this year.

And also, at the moment, OPM does not support simulation with alkaline and surfactant. The error you reported is about reading/parsing the DATA file. The keywords related to alkaline and surfactant will not be handled properly with OPM (most likely, they will not make desirable effects in the simulation results).

[DanatKMGE]

Lots of keyword errors. I can list what I could find: APIVD, TPAMEPSS, SOHF, RADFIN, BCCN, KRNUMX, SOFRF, SSWCR.

I am afraid that is not very helpful, unless you share what kind of error it is. We do have a design goal that Flow should recognize all Eclipse 100 keywords. However, there has been made no attempt to support all keywords or options in the simulator. If you are using an unsupported keyword or an unsupported option in a supported keyword, Flow should give you an informative message to that effect. If not, we consider it a bug.

2. TPAMEPSS - Marked as inactive in the OPM Flow 2021-10 manual.
3. SOHF - Not an E100 or E300 keyword (2019.1 manual). This is a tNavigator SUMMARY vector for Segment oil holdup fraction SOHF.
4. RADFIN - Marked as inactive in the OPM Flow 2021-10 manual. LGRs are not currently supported.
5. BCCN - Not a E100, E300 or tNav keyword.
6. KRNUMX - KRNUM(X/Y/X) marked as inactive in the OPM Flow 2021-10 manual.
7. SOFRF - Not a E100 or E300 keyword. This is a tNav SUMMARY vector for Segment free oil flow rate SOFRF.
8. SSWCR - Marked as inactive in the OPM Flow 2021-10 manual.

@OPMUSER Where can I download the Tech Doc? Does it exist?

[OPMUSER]

@DanatKMGE we don't have a Technical Manual at the moment, it is currently being written. However, we do have a User/Reference Manual that outlines the keywords etc and can be downloaded from here:

https://opm-project.org/?page_id=955

The manual gets updated with every release.

@DanatKMGE In addition to the reference manual linked to above, there is a journal article describing some of the technical details available: https://www.sciencedirect.com/science/article/pii/S0898122120302182

The article is open access.
