Hybrid Blockchain Ledger Sync for Intermittent Oilfield Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain technologies are not suitable for oilfield operations due to intermittent connectivity and limited data rates, making it difficult to deploy and operate a blockchain system in remote environments where reliance on a wide area network is questionable.
Innovation Solution
A local/hybrid blockchain system is deployed on-site with the option to extend to the cloud when connectivity is available, using blockchain nodes to update ledgers and reconcile split branches when connectivity is lost, and employing cryptography operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wide area network blockchain system is used, then tamper-proof records and distributed validation are achieved, but connectivity requirements and data transmission latency increase
Solution Approach 1:
The blockchain network is segmented into local and remote components. Local blockchain nodes operate autonomously at the wellsite, maintaining ledger copies and validating transactions independently. Remote blockchain nodes provide additional validation and synchronization when connectivity is available. This segmentation allows the system to maintain tamper-proof records locally without requiring continuous high-speed connectivity to the remote network.
2Adaptability or versatility
If a local blockchain system is deployed, then connectivity requirements are reduced, but network security and consensus coordination become more challenging
Solution Approach 1:
The local blockchain nodes are designed to perform multiple functions: they validate transactions locally, maintain ledger copies, synchronize with remote nodes when connected, and continue operating autonomously when disconnected. This multi-functionality allows the system to adapt to varying connectivity conditions without requiring separate systems for different operational modes, thereby reducing overall system complexity despite the enhanced operational flexibility.
3Productivity
If high transaction rates are processed, then operational throughput is improved, but network bandwidth requirements and synchronization difficulty increase
Solution Approach 1:
Local blockchain nodes perform preliminary validation and processing of transactions before they need to be synchronized with remote nodes. By pre-validating transactions and maintaining local consensus when connectivity is limited, the system can process high transaction rates locally without immediately requiring network bandwidth for every transaction. Synchronization with remote nodes occurs at convenient intervals when connectivity is available, improving both throughput and synchronization reliability.

AI summary
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.
