Abstract

The static formation temperature of

a petroleum reservoir is relevant for

evaluating its properties. There is a

variety of methods for estimating it.

However, each method assumes different

hypotheses and simplifi cations which lead

to diverging estimations, in some cases far

from the real value. This makes diffi cult

knowing in advance which method to use.

In this paper, the most common methods

(Horner, spheric and radial, two-measures

and cylindric source) are applied to four

different wells. The way of applying them

to real cases is described, paying special

attention to the necessary input data

in each case: especially thermophysical

properties and number of measurements.

Criteria for estimating properties in case

their real value cannot be known are also

provided. The paper concludes suggesting

a decision tree for selecting the most

appropriate method depending on the

available information.
