pre/post stack product

English to French Tech/Engineering Petroleum Eng/Sci seismic acquisition
The individual field records from a single vibrator, single sweep survey may exhibit a lower signal-to-noise ratio than those recorded from a traditional vibroseis survey acquired using either a multiple vibrator fleet operation, or else a multiple summed sweep per VP operation, or else a combination of the two. However, the advantages of the single-sweep point-source become apparent at the processing stage, where the improved spatial sampling allows a wide range of noise rejection and signal enhancement routines to be applied. Both source-generated noise and ambient noise can be eliminated more effectively, and higher frequency reflection signal can be retained through to the final pre-stack or post-stack products
Votes to reclassify question as PRO/non-PRO:

Non-PRO (1): mchd

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.
