Method for determining the profile of an inflow and the parameters of a well-surrounding area in a multipay well |
| abstract |
A method for the determination of an inflow profile and bottom-hole area parameters (perforation zone parameters, bottom-hole area pollution parameters) in a multipay well comprises changing a production rate and measuring a temperature of a fluid flowing into the well as a function of time for each pay zone. Then a derivative of this temperature with respect to a logarithm of a time passed after the well production rate has been changed for each pay zone is determined. An inflow profile and other parameters are calculated based on a value of said derivative when it becomes constant and on a time after which the value of the derivative becomes constant. |
