Abstract: A stack of addressable perforating guns with preassigned addresses may be configured for operation by identifying any duplicate addresses in the stack and deduplicating the addresses by assigning new addresses to at least a subset of any guns having the same address until each gun in the stack has an address unique in the stack.

Abstract: An initiator circuit for a perforating gun includes a microprocessor structured to perform a circuit-startup algorithm comprising determining whether the circuit supply voltage is stable enough for operation and, if it is, or if a predetermined period of time has passed since powering up the circuit, sending a message indicating the circuit (and thus gun) is ready for operation. The sent message may be a communication uplink indicating an address of the circuit and its ready state or a short burst of pulses indicating the circuit's ready state.

Abstract: A method for initializing the input of each of m receiver channels of a receiving transducer in a well logging tool comprising the steps of selecting a logging tool having a multi-element receiving transducer wherein each element of the multi-element receiving transducer operates in an anti-resonant mode below its resonant frequency, and executing a routine in an initialization mode wherein a predetermined number of run cycles are operated and receiver input responses are measured and averaged for each of the m channels while transmitter firing signals are disabled.

Abstract: A longitudinally segmented acoustic transducer for a cement bond logging (CBL) tool having a plurality of adjoining PZT ring-like segments driven synchronously in parallel by one or more pulses and caused to vibrate in an anti-resonant mode, substantially below the resonant frequency of an individual segment when used in a transmitting application. When used in a receiving application, each of the plurality of transducer rings are caused to vibrate by acoustic signals detected by the transducer array, also in an anti-resonant mode. High speed digital signal processing enables on-depth, high quality data for all azimuths at each depth to be obtained, processed, normalized and either sent to the surface in real time for each 20 Hz firing cycle, as the CBL tool is pulled toward the surface, or stored in a memory module in digital form for later retrieval. Built-in calibration factors used for normalizing the output signals to the operating conditions of use may be accessed at any time.
