Then, the oil-soluble viscosity reducer SSM was synthesised by copolymerisation of three monomers of stearyl methacrylate (SMA), styrene (SM) and maleimide (MIm) by solution polymerisation. The effects of monomer ratio, reaction temperature, reaction time and initiator addition on the viscosity reduction effect of Liaohe heavy oil were investigated. Infrared characterisation results showed that SSM was successfully synthesised. Thermogravimetric analysis results show that SSM has good thermal stability and dispersibility. The results of optical microscopy and scanning electron microscopy revealed the viscosity reduction mechanism of SSM on heavy oil.

The ethanol-soluble fractions obtained from YL and TYL (ESPYL and ESPTYL) were analysed using atmospheric pressure chemical ionisation/quadrupole orbitrap mass spectrometry (APCI/Q-orbitrap MS). The yields of ESPYL and ESPTYL were 41.5 wt% and 53.0 wt%, respectively, indicating that the lignite treated with the ionic liquid-methanol co-solvent system exhibited enhanced potential for catalytic conversion. Benzyl-2-naphthyl ether (BNE) was selected as a representative model compound for YL and was fully converted to toluene and naphthol (210°C, 1 h, and 1 MPa N2), demonstrating the excellent ability of Pd-Ru/HZSM-5 catalyst in activating ethanol to generate H• as a hydrogen source for the cleavage of BNE. APCI/Q-orbitrap MS analyses revealed the presence of a significant amount of oxygen-containing products in ESPYL and ESPTYL, underscoring the efficacy of the tandem system in generating oxygen-containing small molecules.

In this study, a better enhancement in the rheological properties of Senna auriculata enhanced water-based mud (SWBM) at 30°C, 70°C and 110°C is observed. Different concentrations, viz., 0.5 wt. %, 1.0 wt. % and 1.5 wt. % of Senna auriculata are used to study its effects on the rheological and filtration properties of WBM. Thermal stability and aging studies are performed for both WBM and SWBM. The experimental results are then modelled using rheological models. The results reveal that Senna auriculata improve the thermal stability and rheological properties of drilling mud and significantly decrease the American Petroleum Institute (API) filtrate. The rheological performance data of NFWDF project a better fit with the Herschel-Bulkley model and suggest improvement in rheological and filtration properties. This study serves as an important prelude for the development of new environmentally friendly, biodegradable, recyclable and cost-effective additives for WBM to improve its rheological properties. This research is also expected to aid the industry by resolving major issues in deep well drilling and HPHT drilling.
