CZERNICHOW 3 1 INSTITUT FRANÇAIS DU PETROLE 1 & 4 avenue de Bois Préau 92852 Rueil-Malmaison France In some areas opportunities for deploying down-hole sensors to perform microseismic surveys can be limited to flowing wells. In this paper we will review some noise sources which affect the ability of on-tubing geophones deployed in flowing wells to monitor reservoir seismicity. The experience of IFP and his partners is based on more than 10 years of
