Crude oil; is known as liquid hydrocarbon, which is formed as a result of the metamorphosis of organic matter on earth. Crude oil is a complex mixture containing paraffin, naphthenes, olefins, aromatic compounds and a small but significant amount of sulphur. During refining crude oil; air pollutants such as COx, SOx and NOx, NH3, H2S, mercaptans, carbonyl sulfide and heavy metals are released. With the legal regulations made in many countries of the world, it obliges the use of environmentally friendly fuels containing less SOx and aromatic compounds. For this reason, an increasing number of studies are being carried out to reduce the number of sulphur compounds in crude oil as much as possible. For the same reason, in this study; firstly CuONPs and MWCNTs were synthesized separately, secondly MWCNTs were decorated with CuONPs the by the CVD method, and the third was characterized by SEM and XPS. Finally, 0.02 to 0.1 g of CuONPs/MWCNTs and MWCNTs were added separately to the crude oil and adsorptive desulphurization was performed with a contact time of 60 and 120 minutes. As a result of the experimental study, it has been determined that the desulphurization efficiency varies between 2.47% and 5.44%.

“…Drilling fluid is indispensable the drilling process, called the blood of drilling [ 12 , 13 ]. It flows in from the drill pipe and out in the gap between the drill pipe and the formation, and it has various effects such as carrying rock chips, protecting the well bore, balancing the formation pressure, assisting in breaking rock, etc.…”

A Novel Amphoteric Ion-Modified, Styrene-Based Nano-Microsphere and Its Application in Drilling Fluid

With the gradual depletion of shallow oil and gas, deep oil and gas has become the focus of development. However, deep formations generally face the challenge of high-temperature and high-salinity, and drilling fluid agents are prone to failure, leading to drilling fluid intrusion into the formation that can cause serious drilling accidents such as well bore collapse. For this, a styrene-based nano-microsphere (SSD) modified with amphoteric ions was developed, with a particle size of 228 nm which could resist temperatures up to 200 °C and sodium chloride (NaCl) up to saturation. SSD has significant salt-responsive properties and its aqueous dispersion becomes transparent with increasing salinity. The SSD provided superior plugging performance in solutions containing NaCl, with a core plugging efficiency of 95.2%, and it was significantly better than the anion-modified microspheres. In addition, in drilling fluids under high temperature and high-salinity conditions, the SSD promotes particle gradation of drilling fluids and improves the zeta potential through its own plugging and synergistic effect with clay, which significantly improves the comprehensive performance of drilling fluids, such as stability, rheological performance, and filtration reduction performance. The development of SSD provides a new idea for research of high-temperature and high-salinity-resistant drilling fluid agents.

“…They stated that the PV value increased 57%, the AV value 36.7%, the YP value 28%, the 10 s and 10 min values increased 33.3% and 44.4%, respectively, and the fluid loss value decreased by 13.8%. 16 As a result of their work by adding 0.001%-0.01% SiO 2 NPs/MWCNTs to water-based drilling mud; they found that PV, AV, YP, 10 s and 10 min, cake thickness values increased by 71.4%, 51.9%, 44%, 25%, 33.3% and 11%, respectively. They also reported that the amount of filtration loss decreased by 13.8%.…”

The effect of multi-walled carbon nanotubes (MWCNTs) decorated with ZnONPs on the rheological and filtration properties of conventional water-based drilling muds (WBDM) was investigated. ZnONPs and MWCNTs were synthesized separately, then MWCNTs were decorated with ZnONPs by chemical vapor deposition method and characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. Synthesized and characterized ZnONPs/MWCNTs were added to conventional WBDM at a rate of 0.001% to 0.01%, and then rheological and filtration loss analyses were performed according to American Petroleum Institute standards. With the addition of ZnONPs/MWCNTs to the conventional WBDM, the values of plastic viscosity, apparent viscosity, yield point, cake thickness, 10 s and 10 min values increased by 42.8%, 31.6%, 28%, 22%, 25%, and 38.9%, respectively, while the value of filtration loss decreased by 13.8%. When all results were examined, the best addition rate was 0.01%. The results obtained show that ZnONPs/MWCNTs improved the rheological and the filtration loss properties of the drilling mud, proving that ZnONPs/MWCNTs can be used as additives in conventional WBDM.
