Abstract
The intercept time method was introduced in the early sixties for the computation of static corrections, when multiple coverage became a usual recording technique. This method gives the velocity of the refractor and the delay times at the shot and receiver positions. These delay times are related to the thickness and velocity of the altered zone. This paper presents a stand alone algorithm for the computation of the formation acoustic slowness and of the delay times from full waveform acoustic data recorded with a multi-receiver tool.
