Seismic While Drilling (Swd) Techniques with Downhole Measurements, Introduced by Ifp and Its Partners in 1990-2000

Abstract: Résumé -Techniques de sismique pendant forage avec mesures de fond, inaugurées par l'IFP et ses partenaires en 1990-2000 -La sismique pendant forage (SWD), comprend toute technique opérée pendant que le train de tige est dans le puits, pendant le forage effectif ou pendant les manoeuvres d'ajout de tige ou de nettoyage. Deux techniques utilisées par l'industrie sont développées ici : -l'écoute sismique du trépan pendant forage (drillbit-SWD), usitée depuis 1986, qui consiste à enregistrer le signal avec un nom… Show more

“…Compared with the conventional VSP and VSP while drilling (VSP-WD) as shown in Table 8, DB-SWD does not require additional downhole explosives or air gun seismic sources. There is no interruption to the drilling operation time, and no risk to wellbore and downhole tools [30,[166][167][168]. The MWD seismic surveying and logging operations can be realized.…”

“…As a result, the clock errors tend to be large and require a significant correction. Fast telemetry, such as wired drill pipe technology (Naville et al ., 2004; Poletto et al ., 2014), may offer real‐time data transmission and an alternative solution to solve the time‐alignment issue using existing tools; however, it has received limited penetration in the industry thus far. This study aims to solve this problem for conventional memory‐based near‐bit sensors with inexpensive unsynchronized clocks experiencing significant and temperature‐dependent drift.…”

“…One way to turn on the 'drilling headlights' is through imaging-while-drilling (IWD) using techniques such as seismic-while-drilling (SWD) used in the petroleum industry (Rector and Marion, 1991;Poletto and Miranda, 2004;Naville et al, 2004;Anchliya, 2006) and engineering (Soma et al, 2004;Reppert, 2013, Zhou et al, 2014. However, realization of SWD is becoming more challenging due to that the rotarycone (RC) drill bit has been replaced by the Polycrystalline Diamond Compact (PDC) bit, which has been identified as a less effective seismic source (Anchliya 2006).…”
