Abstract The drillstring used in the oil and gas exploration is a complex structure due to the different forces acting on it. One of the primary sources of drillstring vibrations is the cutting forces caused by the drill bit contact with the rock for

These data were acquired to estimate the parameters of a closed form solution of a one-dimensional transient convection heat diffusion PDE. The purpose was to demonstrate that the model could be used to determine the thermal conductivity. The system

Wind loading and windborne debris (missile) impact are the two primary mechanisms that result in window glazing damage during hurricanes. Wind-borne debris is categorized into two types: small hard missiles; such as roof gravel; and large soft missil

Electromagnetic (EM) fields at radio frequencies (RF) cannot penetrate deep into media with high conductivity such as sea water, wet soil, etc. However, moving to the ultralow frequency (ULF) range (300 Hz–3 kHz) allows a considerable range of comm

A measurement system which uses acoustic vibration to locate passive-intermodulation (PIM) sources in base station antennas is presented. This measurement system uses mechanical vibration to modulate the PIM signal. The modulation of the PIM signal i

Drill stem vibration may cause drilling inefficiencies and often leads to non-productive time. Drill stem vibration analysis is performed to prevent and identify RPM values that may cause damaging standing waves in the drill stem. However, different
