Assuming you have a list of well numbers (say in column D):


in E1:

=SUMIF(A:A,D1,C:C) where D1 contains the well number

I have extracted reports where oil well numbers are in column A and a related
expense is in column C. I'm looking for a function to that will give me
total expenses per well number.

I've sorted the spreadsheet by well number and then put sum formulas that
add all the column c expenses for a given well number out to the side, but
this is very tedious with over 100 well numbers.

Is there an easier way?
