Unconventional Resources are seen as a key contributor to Saudi Arabia's domestic energy source for electricity generation and water desalination. The investment by Saudi Aramco in unconventional light hydrocarbon resources will reduce the Kingdom's reliance on liquid fuels for utilities and will provide petroleum feedstock for a growing petrochemical industry. Certainly the unconventional work being done in the Kingdom is already benefiting from the experience gained by operators in North America; however, given the fact that there are many fewer well penetrations in Saudi Arabia than in North America, locating and optimizing production with the drill bit is not a viable option for development of unconventional source rock reservoirs. Considering these obstacles and considerable future opportunities, technology development and research support is being provided from both Saudi Aramco's domestic research organization and the Aramco Research Center in Houston. This work involves a multi-disciplinary team consisting of reservoir engineers, geologists, geochemists, chemists and physicists. Evaluation techniques include a combination of high resolution imaging, NMR, vapor adsorption, geochemical analysis and core analysis to identify potential productive source rock reservoirs to quantify hydrocarbons in place, estimate flow rates using reservoir simulation and predict EUR.
