Abstract: Shale gas and tight reservoirs resources emerged as a viable energy potential for the near future. Shale gas particularly and tight reservoirs become vital in characterizing their properties: starting from TOC rating to maturation, gas in place brittleness and low permeability. Thus, it is very harsh to reach a wise economical recovery stage (seepage and flooding). Similar types of resources are classified as unconventional owing to their complexities from their low K to their high pressure mostly exposed to formation damage. Thus, recovery obstacles complicate the unconventional reservoirs exploitation and management. Production from unconventional reservoirs is related not only to their characterisation properties but it is own also to the state of the art technologies in use. Therefore integrated approach is essential to success and, improving methodologies are needed. The contribution of the incorporated breakthrough technologies, surely, will help to stimulate unconventional reservoirs up to commercial production. Beside, alternatives and effective tertiary methods are also present. They consist on the extraction of amount of crude oil-gas based on residual oil in place using the following techniques: thermal recovery, gas injection, and chemical injection. Hence, now days Oil – Gas Recovery revolution is taking place with enormous volume of oil and gas to fill the gap: Not to be feared of running out of fossil fuel but at which price. Different and various laboratory investigations have led to viable results based on core lab analysis. The use of SEM (microstructure pore determination, autopore use for the PSD and geometry determination, Triaxial tests (for mechanical brittleness index) and surfactants use constitutes the most challenging approaches.
