The concept of Ct was first proposed by Fritz Haber and is sometimes referred to as Haber's law, which assumes that exposure to 1 minute of 100 mg/m 3 is equivalent to 10 minutes of 10 mg/m 3 (1 × 100 = 100, as does 10 × 10 = 100). Some chemicals, such as hydrogen cyanide, are
This is the most common method of a contingency well kill. If there is a sudden need to kill a well quickly, without the time for rigging up for circulation, the more blunt instrument of bullheading may be used. This involves simply pumping the kill fluid directly down the well bore, forcing the well bore fluids back into the reservoir. This ...

Killing your entire lawn gets rid of everything—grassy and broadleaf weeds, off-type lawn grasses, and the few strands of good grass you have left. Unlike the five percent household vinegar used ...
Single-well concentric kill string: within the well a small diameter concentric kill string is used to circulate kill fluids when needed. Single-well 2-tubing completion: in this instance 2 tubing strings are inserted down 1 well. They are connected at the lower end by a circulating head.
Add in a generous 4.6% dividend yield today, and you can see why, despite oil prices being weak, you might want to buy Chevron. In fact, the best time to buy it is often when oil prices are weak.
In the context of oil wells, pumping is a routine operation involving injecting fluids into the well. Pumping may either be done by rigging up to the kill wing valve on the Xmas tree or, if an intervention rig up is present pumping into the riser through a T-piece (a small section of riser with a connection on the side).
