Drilling Wells In Compartmentalized Reservoirs

摘要

Method of drilling a well, including one method comprising determining a first value indicative of a relative position of a geological bed boundary with respect to a drilling assembly, determining a second value indicative of an optical property of a formation fluid proximate the drilling assembly, and controlling a well trajectory based on the first and second value.

主权项

1. An apparatus, comprising:
a downhole apparatus configured for conveyance within a well penetrating a subterranean formation, wherein the downhole apparatus comprises:
means for determining a first value indicative of a relative position of a geological bed boundary with respect to a drilling assembly;means for determining a second value indicative of an optical property of a formation fluid proximate the drilling assembly, wherein the optical property is selected from the group consisting of:
an absorption at one or more wavelengths;a fluorescence intensity at one or more wavelengths; anda reflection intensity at one or more incidence angles at an interface between the formation fluid and a light transmitting window; andmeans for controlling a well trajectory based on the first and second value.
