| | July - Aug 20208Oil and Gas industry has recently transformed itself into a data-intensive industry ­ from artificial intelligence to intelligent or cognitive computing, machine learning to internet of things and robotics. With such a growth and expansion, distributed ledger technology, commonly known as blockchain, can carry the industry's transformation forward in the new era of cyber-automation in lockstep with other exponential technologies. Cyber drilling automation software plugins from third party, different tools, and different equipment and IoT devices from various vendors can be on the blockchainas shown in figure 1 as different nodes. This option provides significant improvement in efficiency by radically changing the workflow. This also provides the opportunity to have distributed databases connected at different nodes. This figure 1 shows the options for third party and main contractor to couple their data and algorithms as different blocks in the blockchain in the form of transactions specified as n nodes. Each block contains data from different sources and can be from the same vendor or from different vendors. Whenever a change is made at any block by any vendor, the integrity of the change in the global system can be verified independently and can be immediately updated in the global chain at anytime and anywhere. This provides additional finger printing and immutability of the databases not only trust but also security in the global system as we develop a reliable autonomous platform for drilling automation. This system will ultimately provide a robust platform as we move into artificial enabled framework.Figure 2 shows the drilling automation glide path. At higher level it can be classified as· High dimensional uncertainty control· Tactical autonomics controlThe separation point is called drillers dilemma or drillers delusion and post delusion point the blockchain technology plays an important role as the network GOLDEN CROSS ­BLOCKCHAIN AS INFRASTRUCTURE IN OIL AND GAS DRILLING AUTOMATIONFig. 1: Blockchain as infrastructure for Drilling Automation.By Dr.Robello Samuel, Chief Technical Advisor & Halliburton Technology Fellow, HalliburtonIN MY OPINION
