Abstract
A downhole tool for determining laterals in a borehole wall or a borehole casing, comprising a tool housing extending along a longitudinal axis and having a circumference perpendicular to the longitudinal axis and a plurality of sonic transceivers. Each sonic transceiver transmitting sonic signals from the housing and receiving sonic signals reflected from the borehole wall or borehole casing in a predefined angular segment. The sonic transceivers are arranged along the circumference of the tool housing having a mutual distance and are capable of transmitting sonic signals radially away from the tool housing in an entire central angle of 360 degrees towards the borehole wall or borehole casing. During a pulse time, one sonic transceiver transmits a sonic signal in the predefined angular segment of that sonic transmitter, and one sonic transceiver, during a subsequent echo time, receives a reflected sonic signal from the borehole wall or borehole casing.
