Special Issue Information

Dear Colleagues,

The economic, environmental, and societal environments of the oil and gas industry are becoming increasingly challenging. This translates into increased pressure on the well creation process, and the corresponding efficiency requirements are expected to be stronger and stronger in the future. In order to meet those requirements, significant gains in performance, safety, and reliability need to be achieved by the drilling community. Technology is the core component of the necessary transformation our industry goes through, and one can expect the emergence of new and innovative solutions in the near future. New technologies typically materialize through the combination of deeper understanding of the physical process, improved sensing capabilities, digitalization of the environment, advanced control techniques, and automation solutions.
This Special Issue welcomes original contributions within innovative drilling technologies, covering the entire well creat process. In particular, recent developments in drilling modeling, drilling sensors, drilling fluid design, bit technology, drilling process control and automation, or cementing are of special interest, but the Special Issue is not limited to those topics.

Gas-lift dual gradient drilling (DGD) is a solution for the complex problems caused by narrow drilling windows in deepwater drilling. Investigations are lacking on using oil-based drilling fluid in DGD, which is the principal novel idea of the present study. This research compares the results obtained from two new models with those of Standing’s correlations for solubility and bubble point pressure. Nitrogen was selected as the injection gas, then the PVT behavior of drilling fluid (oil/water/Nitrogen) in gas-lift DGD was evaluated and compared by coding in MATLAB. Then, these results were used to calculate the bottom hole pressure and finally investigate the optimization of injected gas flow rate. According to the achieved results, the Standing model has some errors in evaluating the PVT behavior of “Nitrogen and oil-based drilling fluids” and is not recommended for the mixtures in the gas-lift DGD. Regarding optimizing gas flow rate, a discrepancy was observed between pressure values obtained from the new models and the Standing model for the case of high liquid flow rates at low gas flow rates because of the difference in PVT parameters. The developed codes are deposited on an online data repository for future users. This study lays the foundation for better planning of drilling in deepwater drilling projects. Full article

The recovery of oil and gas from underground reservoirs has a pervasive impact on petroleum-producing companies’ financial strength. A significant cause of the low recovery is the plugging of reservoir rocks’ interconnected pores and associated permeability impairment, known as formation damage. Formation damage can effectively reduce productivity in oil- and gas-bearing formations—especially in sandstone reservoirs endowed with clay. Therefore, knowledge of reservoir rock properties—especially the occurrence of clay—is crucial to predicting fluid flow in porous media, minimizing formation damage, and optimizing productivity. This paper aims to provide an overview of recent laboratory and field studies to serve as a reference for future extensive examination of formation damage mitigation/formation damage control technology measures in sandstone reservoirs containing clay. Knowledge gaps and research opportunities have been identified based on the review of the recent works. In addition, we put forward factors necessary to improve the outcomes relating to future studies. Full article
