In the previous era of oil and gas, conventional natural resources like coal were hard to find and costly to attain. In the search for an easily obtainable energy source, shale gas entered the limelight and has become an increasingly important natural gas since the early 21st century. In his recent study "Smart Management of Unconventional Oil and Gas Wells," Professor Sung Won-mo (Department of Earth Resources and Environmental Engineering) designed AI technology which manages a more efficient method of shale gas production.

Professor Sung Won-mo (Department of Earth Resources and Environmental Engineering)'s recent study aims to develop an AI management technology for the most efficient production of shale gas.


Natural gas is extracted through wells that are drilled two to three kilometers deep from the ground. The conventional production of gas was an extremely uneconomical procedure, primarily because the source of gas is concentrated within a very small area, thus being difficult to find. For instance, while extracting marine gas a kilometer under the sea costs more than 100 billion won, its success rate hovers at three percent.

Shale gas (natural gas extracted from shale, which is a fine-grained, laminated sedimentary rock consisting of silt and clay-sized particles), on the other hand, is an unconventional energy source that tends to be found over a wide area, hence is much easier to locate. For this reason, shale gas has become a very important energy source. “Gas consumption will reach its peak in 2050. Until the end of the 21st century, securing the gas supply will be very important, and shale gas is a highly productive and cost-efficient energy source,” said Sung.

Sung’s research focuses on developing AI management technology for the most efficient production of shale gas. Attaching an AI sensor onto the well allows it to collect and analyze related data to ensure the most precise and efficient production procedure. “The data we collect from the sensor is so vast that it is impossible to be analyzed by humans or with a regular computer. However, AI learns from the information and analyzes the new data with impressive speed and accuracy,” explained Sung. The model will help predict the type of rock, type of gas, and components of gas according to the depth. As the result, more accurate drilling and product predictions will be possible, ultimately lowering the unit cost of gas.
 

Sung said he has been aware of the prospect of shale gas for a long time and hopes that in the future, the new technology will help secure this gas resource for Korea.


“Korea does not possess many natural resources and relies heavily on imports,” added Sung. “I hope this new technology can be developed further so that it can be implemented in policies, helping to secure this gas resource in Korea.”
