(1) Disassembled (2) Now installed in Chac-A platform. Not operating satisfactorily(3) Operating (4) Service concluded satisfactorily (5) Operating but..
The portable MPFM allowed measurement of many wells production, where it wasnot feasible to use conventional well testing systems.
The use of MPFM through a turnkey well testing service demonstrated to be asuccessful option for well testing operations in Mexico.
MPFM are not attractive alternatives for well testing in Pemex if reliability cannotbe confirmed.
Because of operational problems of installed units, probably only few MPFM willbe installed in Mexico in the coming years.
