New coiled tubing conveyed tool sees ahead of the drill bit

摘要

The efficient exploitation of hydrocarbon resources is strongly dependent on the driller's ability to position wells accurately within the reservoir. This is particularly challenging for smaller accumulations and on long reach or horizontal wells. Conventional wireline vertical seismic profiles (VSPs) can provide valuable assistance, but such operations require either the drill string to be removed from the hole or the pumping of the geophone tool through the drill string. Both of these methods add time to the well construction.
