Sich erden, Frieden schließen, das innere Feuer neu entfachen, Vertrauen wachsen lassen oder die eigene Bestimmung erkennen: Kraftrituale machen all das möglich. Ob im Wald, im Park, am Wasser oder im Gebirge – in der Natur sind wir näher bei un

The push in the drilling industry for drilling longer wells, and faster and more difficult trajectories leads to increasing challenges with the dynamics of the drilling systems in particular in expensive high end offshore wells. Dynamic effects are m

Different vibration phenomena and vibration dysfunctions are excited by the drilling process. The associated dynamic loads result in downhole tool failures and inefficient drilling if not properly managed. Vibration mitigation strategies based on adj

High Frequency Torsional Oscillations (HFTO) generate high torsional loads in the BHA causing cracks, damaged electronics or twist-offs. A new Torsional Vibration Isolator tool (TVI) protects the BHA by restricting vibrations to the tools between bit

Colorimetric analysis is widely used for fast and cost effective determination of the concentration of chemical compounds in both liquids and gases [1] – [3] . Some well-known examples include test strips for pH measurement, and urine test, but suc

Sich erden, das innere Feuer neu entfachen oder einfach pure Lebensfreude zum Ausdruck bringen: Kraftrituale machen es möglich. Ob im Wald, im Stadtpark oder am Strand – in der Natur finden wir zurück zu unserem Ursprung und damit zu uns selbst.

Self-excited torsional vibrations of the bottomhole assembly (BHA) at frequencies above 50 Hz, so-called "high-frequency torsional oscillations" (HFTO), can damage drilling tools and can increase non-productive time (NPT). A recently developed HFTO-i

Monolithic integration of 3-D Hall effect sensors makes it feasible to measure all three spatial directions of magnetic fields. However, even if the integrated sensors are arranged strictly orthogonal in the semiconductor layout, measurements have sh

The quasibinary section of the intermetallic phases MAl4 and MGa4 with M=Sr and Ba have been characterised by means of X-ray diffraction (XRD) studies and differential thermal analysis. The binary phases show complete miscibility and form solid solut

Summary Since they were first introduced to the market decades ago, polycrystalline-diamond-compact (PDC) bits have undergone numerous technological improvements. One such example is depth-of-cut (DOC)-control technology. Introduced in the early 2000
