... during microchips circulation. It is shown that the true velocity of tracers in each interval depends on the flow regime and the rheological properties of drilling fluid. Comparing the predicted arrival times of tracers with the actual arrival times conclude that the maximum fluid velocity in each...

... Abstract Fiber-containing drilling fluid enhances hole cleaning or cuttings transport efficiency without significantly affecting the rheological properties of the base fluid. Objective of this study is to evaluate the hole cleaning capability of a novel seawater-biodegradable polymer fiber...

... Abstract The improved rheological properties of the drilling fluid are very critical for the oil well drilling operation. The present work reports the effect of sodium dodecyl sulfate modified graphene (SDS-Gr) on the rheological features, fluid loss and swelling inhibition mechanism of clay...

..., the invasion depth and invasion rate of the fluid into the sand bed was reported, also rheological properties and API Fluid loss were measured. According to the results, invasion depth and invasion rate of fluids containing designed WSMs is magnificently lower in comparison with drilling fluids which...

... drilling fluid resulted in a decrease in rheological properties. The filtration experiments also showed that filtrate volume has increased with the addition of KCl and ionic liquids in the drilling fluids. The hot rolling shale recovery experiment was performed at 65°C and superior shale recovery...

... of flow resistance and consequently decrease of fluid viscosity. Methods Rheological properties of non-Newtonian fluid can be measured by a variety of instruments, such as capillary rheometer, rotating cylinder viscometer and control stress rheometer etc. They have their own characteristics...
