Petrobras, the only oil company in Brazil, has now a project to
evaluate the potential of the NMR technique for lab. determination of T1/T2
(bulk and surface), porosity, permeability, diffusion, etc. in core samples
of a well.
The literature (cf. Watson,T. et al. AIChE Journal 1996, 42, 538) is
definitive regarding NMR as a powerful tool for the characterization of porous
media. Nevertheless, prior to any decision of buying a low resolution
instrument,
we would like to have our samples analyzed by a lab. that performs this kind
of analyses routinely. We would like to know, then, if anyone in the AMMRL
knows
of such labs, and ask if it is possible to forward this information to us.
Furthermore, we would like to inquire if anyone in the AMMRL list is researching
in this field, and if there is(are) specific instrument(s) recommended for
gathering core sample NMR data.
We thank you in advance.
Sincerely,
Carlos R. N. Pacheco
