Mini frac anaylsis using saphir

[amramazon88]

Hi everybody,

Wish all fine here

Does anybody use saphir for minifrac test before?

Thanks,

What I understand by mini frac analysis is the downhole stress measurement by use straddle packer on a wireline. This is used to measure fracture closure pressure to get an idea of minimum horizontal stress.

I have no experience with this but looking around I found this information.

OK, temr knows Russian better than I, but I found a discussion of mini-frac and Saphir here,

[link Point to another website Only the registered members can access] Saphir has G-function analysis so it seems something could be done but one person seems to imply that the mini frac is too short to give reliable information. Another person says that it can be used as a order of magnitude estimate.

Perhaps temr could give us a quick interpretation of the discussion.

Put this into GOOGLE as it seems that FEKETE has more info publicly available.

Take a look at this paper
