Asphaltene deposition effects on reservoir rock wettability and modification strategies.

Asphaltene deposition, a widespread challenge in the petroleum industry, detrimentally affects oil production, transport, and processing. Our study investigates asphaltene's impact on sandstone and carbonate reservoir rock wettability using ASTM-D6560 extraction and heptol solutions. A significant part of our focus was to examine wettability change due to asphaltene damage and the use of nanoparticles to improve this situation.

Evaluation of a water-based spacer fluid with additives for mud removal in well cementing operations.

This research evaluates the crucial role of effective well cementing in enhancing petroleum production, with a specific emphasis on the utilization of spacer fluids for pre-cementing well cleaning. Investigating the performance of a water-based spacer fluid enriched with barite, Xanthan Gum, potato starch, and Poly-Anionic Cellulose additives, this study systematically designs and evaluates three distinct spacer fluids featuring varied additive concentrations for optimal mud removal efficiency. Notably, Spacer B1, incorporating 0.
