Resistivity tool with selectable depths of investigation
Abstract:
A wireline tool string used in a wellbore to determine formation properties is disclosed which comprises one or more transmitter tools disposed within the tool string, each transmitter tool having three linearly independent coils; a receiver tool disposed within the tool string, wherein the receiver tool has three linearly independent coils; and a tool string component disposed between the one or mole transmitter tools and the receiver tool; wherein the one or more transmitter tools are selectably spatially separated from the receiver tool along the tool string to provide a desired depth of investigation and measurements made using the one or more transmitter tools and receiver tool are used to determine formation properties.
