“…This results in the volumes of drilling fluids in the mud tanks to drop. It is a common and serious wellbore drilling problem and is often associated with the invasion of drilling fluids into the large-scale formation fractures or underground cavities [20]. Sometimes incorrect information or anticipation of the pore pressure and fracture pressure of formation being drilled causes an inappropriate mud weight to be deployed leading to severe overpressured or underpressured conditions at the bottom hole.…”

“…The availability of sufficient water resources to make up adequate volumes of drilling fluid is always essential before drilling operations begin, because future potential mud losses could require more weighted drilling fluid to be required at short notice [20][21][27][28]. When a drilling operation encounters a loss of circulation problem, the following sequential steps are necessary.…”

Sustainability in petroleum wells drilling operation systems strongly depends on the use of sustainable materials and a set of technical and safety measures that lead to the survival and proper operation of drilling rig equipment's and personnel. Adherence to the highest levels of standards of tools, materials and methods, although always recommended as the most important option for advancing a safe drilling operation and completing the well efficiently, low risk and stable, but drilling operation is inherently a battle with underground challenges and unexpected dangers. Learning from past such well blowout events and the problems they pose to rapidly control is essential to reduce future impacts including injuries, damage and emissions. Such analysis offers guidance for adapting working practices to improve both prevention and emergency response to such incidents. The causes of blowout during drilling and the necessary technical and safety measures to adopt are reviewed, highlighting how best practices can prevent blowout incidents by improving responses to early warning signals. The particular risks associated with potential shallow gas blowouts are identified and described with the aid of a case study associated with a catastrophic blowout of an onshore well in Iran and the methods used to ultimately control it. The multiple causes of the incident relating to defects in safety systems, equipment and operating procedures are addressed. Lessons learned from the incident reveal the complexity of well control once a blowout incident has occurred and developed into a surface fire. from the stage of the incident to fire control. There is a need for further research into top-hole well kill techniques for wells in a blowout state, as drilling bottom-hole relief wells takes substantial time, during which much surface damage, resource loss and emission typically occurs.

“…Drilling fluids are combinations of solid materials as additives in varying concentrations present as non-continuous forms dispersed in a constant liquid form [86]. Drilling fluids, which represent 25-40% of the cost of petroleum-drilling operations [87], should be straightforward to use, low-cost, and harmless to the environment. Drilling fluids are designed to achieve different operational objectives; these include cooling the drill bits, helping to clean the holes of drilled wells by transporting drill cuttings to the surface while maintaining wellbore stability, and preventing the invasion of formation fluids into the wellbore by creating an ultralow-permeability layer (called a filter encrust) on the walls of the wellbore.…”

Minimizing Formation Damage in Drilling Operations: A Critical Point for Optimizing Productivity in Sandstone Reservoirs Intercalated with Clay

2021

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.

“…Simultaneous transport of fluids and solid particles through rock fractures is ubiquitous in the Earth's crust with relevance in many geophysical phenomena and subsurface engineering and environmental applications, including dynamic stress (e.g., due to seismic waves) induced fracture unclogging (Candela et al., 2015; Barbosa et al., 2019; Y. Zhang, Manga, et al., 2022), hydraulic fracturing (Baldini et al., 2018; Jalali et al., 2018; Parisio & Yoshioka, 2020; Salimzadeh et al., 2020; Tong & Mohanty, 2016), borehole drilling (Elkatatny et al., 2020; She et al., 2020; M. B. Wang, Guo, & Chen, 2020), particulate contamination (Flury & Aramrak, 2017; He et al., 2023; Wu et al., 2021), and enhanced oil recovery (Aben et al., 2017; Baldini et al., 2018; Jasinski & Dabrowski, 2018; Liang et al., 2016; Woodworth & Miskimins, 2007). Fluids and particles can mix to form suspensions, and the flow dynamic of suspension in rock fracture is complex.…”
