Abstract
Official abstract text for this publication.
A resistivity array having a modular design includes a transmitter module with at least one antenna, wherein the transmitter module has connectors on both ends adapted to connect with other downhole tools; and a receiver module with at least one antenna, wherein the transmitter module has connectors on both ends adapted to connect with other downhole tools; and wherein the transmitter module and the receiver module are spaced apart on a drill string and separated by at least one downhole tool. Each transmitter and receiver module may comprise at least one antenna coil with a magnetic moment orientation not limited to the tool longitudinal direction. A spacing between the transmitter and receiver module may be selected based on expected reservoir thickness.
First claim
Opening claim text (preview).
What is claimed is: 1. A method to control a drilling direction while drilling a wellbore, comprising: providing a modular downhole apparatus including a plurality of modules, incorporated into a drill string, wherein each module in the modular downhole apparatus has one or more antennas, connectors on each of first and second opposing ends, and is removeably connected to the drill string; making measurements with one or more antennas of a module of the modular downhole apparatu…
