Summary Undetected gas kicks are at the root of many disastrous accidents in the oil industry. A major factor in these tragic outcomes is the suddenness with which oil and gas can be ejected from the top of the riser, which gives operators virtually

The work described here originated from the tragic and ultimately environmentally catastrophic event at the Macondo well in April 2010. The first part of the paper addresses the causes for the sudden and often destructive ejection of hydrocarbons fro

Summary In deepwater wells, if gas comes into the riser, a rapid unloading event may occur if removal of the gas is not carried out properly. Oil-based muds (OBMs) present an even greater challenge when compared with water-based muds (WBMs) to avoid

Lead-free positive temperature coefficient of resistance (PTC) thermistors were synthesized from (1 − x/100)BaTiO3–(x/100)(Bi1/2K1/2)TiO3-based solid solutions, using a conventional mixed-oxide fabrication route, and sintered in N2 followed by ai

In deepwater dual gradient wells, if gas comes into the riser, a rapid unloading event may occur if removal of the gas is not carried out properly. Oil based muds present an even greater challenge when compared to water based muds to avoid gas in ris
