... different models were used to match the rheological properties including the Bingham model, the power-law model, and the Herschel–Bulkley model. The results showed that the prepared drilling mud density was correlated exactly with the amount of ilmenite added to the formulation. Similarly, the viscosity...

...-wellbore and through the annulus. Mixing non-Newtonian fluids is one of the most challenging tasks, especially for pseudoplastic fluids exhibiting yield stress, such as wellbore cement slurry. Mixing conditions for cement slurries and their effect on rheological properties and thickening time have been...

...Lionel Talley Fogang; Muhammad Shahzad Kamal; Mohamed Mahmoud Viscosified acids are desired in several oilfield applications such as in acid diversion and acid fracturing operations. The study aimed to delineate the rheological properties of a novel amine type surfactant and viscosified acid...

...Pengfei Liu; Mingming Zhu; Zhezi Zhang; Dongke Zhang This study was aimed to understand the rheological properties and stability characteristics of biochar-algae-water (BAW) slurry fuels prepared by wet milling. A pine sawdust biochar and a chlorella vulgaris algae were used in preparing the slurry...

...Musaab Magzoub; Mohamed Mahmoud; Mustafa Nasser; Ibnelwaleed Hussein; Salaheldin Elkatatny; Abdullah Sultan The rheological properties of bentonite suspensions depend on the chemical composition and the contained dominant element, such as calcium (Ca), potassium (K), and sodium (Na). Na-bentonite...
