Abstract

When drilling horizontal drains in a thin layer environment, one of the main challenges is to maximise the reservoir exposure,<br>which means remaining in the pay zone as long as possible and at the same time avoiding or at least identifying any possible<br>water conductive events. Considering that an angular difference of only one degree between the well bore axis and the<br>apparent dip of the formation along the well path results in about half a metre vertical shift every drilled stand, remaining<br>within a one or two metres thick reservoir requires a better precision for an optimal reactivity in the geosteering process.
