The present disclosure relates to a system that is operable to receive an execution plan and execute a control operation on one or more equipment based operations within the execution plan. The one or more operations may include a data capturing operation associated with a resource site. In one embodiment, the system may be operable to execute at least a first operation in response to a success variable of the data capturing operation indicating a successful execution of the data capturing operation. The first operation may include a quality control operation that is executed by comparing at least one characteristic of the captured data to an expected characteristic to generate quality state data. The quality state data may have one of an acceptable status and an undesirable status. In response to the quality state data indicating an acceptable status for the quality control operation, executing at least a second operation.

Autonomous operations in oil and gas fields

Methods and systems for blockchain-related systems for oil and gas infrastructure are disclosed. In one aspect, a blockchain-related system includes a node disposed at an oil or gas infrastructure site, the node including a memory configured to store blockchain data; and a processor configured to: receive a first data item to append to a blockchain; add the first data item to the blockchain; but when communication to a second node is not available, the blockchain-related system may split the blockchain and add the first data item to the split blockchain.

Local/hybrid blockchain for oil and gas operations integrity

A wireline services system server can include a processor; memory operatively coupled to the processor; a network interface; at least one wireline services equipment interface; and processor-executable instructions stored in the memory executable to instruct the wireline services system server to operate in a user interactive mode via receipt of client communications via a network connection at the network interface; operate in an automated mode; and operate in a safe mode responsive to interruption of a network connection at the network interface.

Wireline services system

Systems and methods may include sending, to a downhole tool emulator, at least one input signal that represents one or more conditions in a simulated well system. The downhole tool emulator may include one or more electronic components to be placed in a downhole tool. The at least one input signal may be generated based at least partially on a reservoir model of the simulated well system. The method may include receiving at least one output signal that represents a response of the downhole tool emulator to the one or more conditions. The method may also include sending, to the downhole tool emulator, at least one command that represents an operation of the downhole tool emulator. The at least one command may represent a change in the operation of the downhole tool emulator based at least partially on the one or more conditions and the response.

Testing downhole tools in a simulated environment

Toolstring topology mapping systems having a downhole toolstring including a master node controller and a plurality of nodes and related methods. The methods involve querying each of the plurality of nodes in the downhole toolstring for actual topology information, receiving actual topology information from each of the plurality of nodes in the downhole toolstring in response to querying, and generating a topology map of the downhole toolstring based on the actual topology information from each of the plurality of nodes in the downhole toolstring. The methods can also involve comparing the topology map with the input topology information to identify topology mismatch and then take remedial actions if needed.

Toolstring topology mapping in cable telemetry

Systems and methods for toolstring communication in cable telemetry. The methods involve positioning a cable telemetry system in a wellbore. The cable telemetry system can include a surface modem, a downhole toolstring of downhole tools, a downhole modem operatively coupled to the downhole toolstring, a cable operatively coupling between the surface modem and the downhole modem, and a surface data routing module that polls and trains the cable telemetry system. The methods also involve performing a pre-transmission poll of a rate requirement for the downhole toolstring and a telemetry type for the downhole modem, applying a training phase to establish a transmission link between the surface modem and the downhole modem, configuring data obtained by the downhole toolstring for an uplink via the transmission link, and transmitting the uplink via the transmission link.
