modify string to get variable working

I have the following list:

faultsPackage1
faultsPackage2
faultsPackage3
faultsPackage4
faultsPackage5
faultsPackage6
faultsPackage7
seafloor
topLowerMiocene
topMetamorphicBasement
topMiddleEocene
topMiddleMiocene
topMiddleOligocenetoUpperEocene?
topPlioceneFromODP684
topUpperMioceneFromODP684

but I need to shape those rows like this (specifically change only those "faultsPackage"):

faultsPackage
faultsPackage
faultsPackage
faultsPackage
faultsPackage
faultsPackage
faultsPackage
seafloor
topLowerMiocene
topMetamorphicBasement
topMiddleEocene
topMiddleMiocene
topMiddleOligocenetoUpperEocene?
topPlioceneFromODP684
topUpperMioceneFromODP684

because these names represent variables, and these variables will pop up some further processes. I tried:

sed 's/[1-7]//'

but it deletes all numbers in the list, so it's not useful. I was thinking that, for instance, in somehow it could only be detected the letter "e" followed by numbers from 1-7 and then delete those numbers, but not sure how to implement that in shell.

Any hint will be appreciated, thanks in advance.

This sed should work:

sed -i.bak 's/\(faultsPackage\)[0-9]*/\1/' file

This regex finds all lines with faultsPackage<number> text and replaces it with just faultsPackage using captured group #1
