..., and higher possibility of inducing formation damage. Ilmenite is a weighting material that is used to increase the density of the drilling fluid. The effect of ilmenite dosage on the density of drilling fluid, rheological parameters, filtration, and filter cake qualities was explored in this study. Three...

...Saad Alafnan Drilling fluids are designed carefully to yield filter cakes with good performance. Fine-scale assessments have revealed that the filter cake has two distinct layers: an internal layer that is close to the surface and an external layer that is close to the drilling fluid. Polymer...

... approximately the same accuracy as does the full Founargiotakis model. It is shown that the use of such a parallel plate model gives reasonably good fit to measured data on laminar flow of oil-based drilling fluids if the viscous data are measured at relevant shear rates for the flow. Laboratory measurements...

... fluid was formulated, evaluated, and applied to well-drilling operations in a sandstone oil reservoir with low-permeability in the Shengli Oilfield, China. To formulate this low-damage drilling fluid, filter-cake forming agents were used to prevent fluid loss, inhibitors were used to enhance the shale...

...Abo Taleb T. Al-Hameedi; Husam H. Alkinani; Mohammed M. Alkhamis; Shari Dunn-Norman Practically, to regulate filtration characteristics of drilling fluid, non-biodegradable materials used commonly have a high cost with side effects on personnel safety and the environment. Hence, eco-friendly...

... the wellbore expectedly depends on its capability in maintaining its integrity and providing the barrier to isolate pressure and fluid transmission between the wellbore and fractures. In this research, a modified permeability apparatus was used to evaluate the quality of drilling fluid filtercakes. A new...

...Jia Wei; Yuanfang Cheng; Chuanliang Yan During the drilling of shale formations, drilling fluids can intrude into the wellbore, raise the pore pressure, and lead to wellbore instability. Based on the thermodynamic theory, a new model was established to calculate pore pressure. The model considers...

... if the concentration of H 2 S is low. The objectives of this paper are to (1) evaluate copper nitrate as an H 2 S scavenger while drilling sour horizontal and multilateral wells and (2) investigate the effect of copper nitrate on the drilling fluid rheological properties and drill pipe corrosion. The obtained results...

...Mohamed Mahmoud The well clean-up process involves the removal of impermeable filter cake from the formation face. This process is essential to allow the formation fluids to flow from the reservoir to the wellbore. Different types of drilling fluids such as oil- and water-based drilling fluids...

... type is the one used in drilling fluids, because it has good dispersion stability, high swelling capacity, and outstanding rheological properties. Ca-bentonite generally has bad rheological performance; however, it can be activated by sodium to be used in drilling fluids, since there are huge...

...M. Nasiri; S. N. Ashrafizadeh; A. Ghalambor Ester-based drilling fluids based on aliphatic esters were introduced in 1990. Esters can be synthesized from fatty acids and alcohols. Previous studies indicated that ester hydrolysis in drilling fluids happens only under certain conditions. In order...
