Experimental Analysis of the Effect of Fine Milled Husk of Rice as a Novel Filtration Control Agent for Water Based Drilling Fluid System
Abstract: Drilling operation is a complex process that requires integration of various engineering systems. As the drilling continues, the formation encountered offers challenges to wellbore integrity as pressure increases with depth. The influx of formation fluid is contained by the overbalance provided by weighted drilling fluid column. Another critical function of the mud is to restrict the filtration fluid lost to the formation by forming a suitable mud-cake around the wellbore. …

Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …
