A technique for monitoring valve and pump efficiencies for positive displacement pumps. The techniques include utilizing a data acquisition system to attain intake and discharge pressure data in combination with real-time encoder position data. Thus, when combined, output from a pump may be monitored in real-time. As a result, pump life may be extended beyond an anticipated changeout schedule. By the same token, premature pump inefficiencies may also be detected for taking a pump offline in advance of expected life. In either circumstance, multi-pump operations may be substantially enhanced with cost and time savings realized.

Automation agents are utilized to modify operating characteristics of a client, such as a piece of equipment. An operating characteristic of equipment can be selectively adjusted by modification of a set point value, which is associated with the operating characteristic of the equipment. The equipment can adjust the operating characteristic based upon the set point value. A remote control indication can be provided to indicate when a set point value is available for modification. The remote control indication is adjustable by an execution module associated with the equipment. A set point latch can be provided for indicating when the set point value is modifiable by an automation agent.

Data transmission from a bottom hole assembly (BHA) includes obtaining a scan from multiple scans forming a downhole data log of a borehole within a subterranean formation. The scan includes a sequence of data items from a sensor in the BHA located in the borehole. Each data item corresponds to an azimuth angle of the sensor. Further, compressed scan data is generated from the sequence of data items on a per-scan basis, and transmitted, using a pre-determined borehole telemetry, to a surface unit.

Systems and methods for monitoring and/or operating a rig site system are provided. In accordance with one embodiment, a method for monitoring a rig site system may include obtaining sensor data at a rig site and transmitting pre-processed sensor data pertaining to the sensor data from the rig site over a network link to a monitoring site. The method may also include demodulating the pre-processed sensor data at the monitoring site to produce demodulated data. The method may also include analyzing the demodulated data at the monitoring site. The sensor data may comprise at least one of surface sensor data, MWD sensor data, or LWD sensor data, or any combination thereof.

Methods and systems for pulse generation assembly that includes a plurality of staged valves operably coupled serially in a bottomhole assembly of a wellbore tool. The plurality of staged valves are operated in a substantially synchronized manner, thereby generating a series of pressure pulses. The signal strength of the generated pulse signal is multiplied by the number of staged valves in the series, and the pulse generation assembly of the disclosure is less susceptible to jamming, shock, and erosion. Further, by sequentially stopping at least one stage of the assembly and then synchronously rotating other stages, amplitude modulation is accomplished.

Multi-stage modulator

Systems and methods compress data and control data compression in borehole communication. The systems and methods convert original data collected by a sensor from a first domain into a second domain, wherein the original data is associated with one or more properties of an underground formation. A predetermined number of significant coefficients is selected from components of the second domain, wherein the predetermined number of significant coefficients are components of the second domain with largest amplitudes. The selected predetermined number of significant coefficients is quantized via an quantization technique and the selected predetermined number of significant coefficients is encoded into compressed data via an encoder.
