Unconventional Reservoir Completions

The world’s oil and gas consumption is rapidly increasing as new tools are invented, new types of energies are taking over the industry and companies are developing them in terms of efficiency, profitability and environmental footprint. Unconventional resources have been introduced as substitutes and the interest has been increasing especially in the last decade. Therefore, the demand for new technologies to develop and exploit these resources has escalated rapidly. In fact, these resources have always been followed by challenges, amongst which is accessing the reservoir. A better understanding of the geological and geomechanical parameters that characterize the different unconventional resources, from shale and tight reservoirs to coalbed methane, enhances the chances of success and the quality of the decisions made throughout the project. In other words, discerning the specific differences between conventional and unconventional, in terms of reservoir properties, drilling and completion, leads to the understanding of the importance and necessity of fracking, but also the risks and environmental impacts that come with it and that could be avoided with simple management techniques.
