Conventional filtration reducers are often limited by poor biotoxicity, necessitating the development of environmentally friendly alternatives. In this study, a novel melamine resin-based filtration reducer (MHAN) has been synthesized, exhibiting exceptional thermal stability (up to 302°C). The addition of 3.0 wt % MHAN has reduced the filtration volume of a saturated brine bentonite-based drilling fluid from 162.2 to 8.2 mL and decreased the filter cake thickness from 3.2 to 0.8 mm demonstrating an excellent filtration control. After aging at 200°C, the saturated brine drilling fluid system containing 5.0 wt % MHAN with a density of 2.3 g/cm<sup>3</sup> maintains stable rheology and filtration control performance. Notably, MHAN is sulfur-free and exhibits high environmental compatibility, with an LC<sub>50</sub> value of 78,500 mg/L.

Distribution density plots were presented for all the composition parameters measured. It was demonstrated that, because all the parameters exhibit polymodal distribution and substantially deviate from normal, a nonparametric statistical analysis is needed for the data processing. In particular, medians and median confidence intervals, rather than means or root-mean-square deviations, should be relied upon. When compared to the crude oil composition in the previously explored OGBs, the Timan–Pechora crudes were found to be closest to the West Siberian OGB. A considerable difference in aromaticity was observed compared to the East Siberian and North Caucasus oils. An equally large difference between the Timan–Pechora and North Caucasus oils was found for the <i>n</i>-alkyl composition characteristics. The average length of <i>n</i>-alkyl moieties in the Timan–Pechora OGB markedly exceeds that in the East Siberian crudes.

The results indicate that the majority of the samples were characterized by a poor to fair content of organic matter, with the total organic carbon (TOC) values less than 1%. These samples were composed mainly of type III (gas prone) and type IV (non-generative) kerogen, with the hydrogen index (HI) &lt; 150 mg HC/g TOC.

The maturity levels across the well ranged from immature to post-mature, with vitrinite values varied within 0.58–2.56%. The burial history modeling in the OSD-1 and TE-3 wells indicated that the hydrocarbon generation from the Carboniferous source rocks started during the Late Carboniferous–Permian period, i.e., during the Hercynian orogeny.
