Historically, the formulation of the wellbore temperature profiles during drilling, circulating, and cementing operations relied upon the boundary condition or BC at the bottomhole location, wherein the tubular and annular temperatures become equal.
The optimal tank-to-wheel efficiencies, ratios of circulating power, and operation points at specific vehicle speeds and out loads are calculated.
Accurate predictions of wellbore temperature and pressure profile are essential for underbalanced drilling operations while circulating aerated drilling fluids in deep water wells.
"We will fire at anything or anyone that tries to censor WikiLeaks, including multibillion-dollar companies such as PayPal," a statement circulating online, apparently from Operation Payback, said.
The pitch is almost identical -- in tone, at least -- in the Ninth Senate District here in the Rockville Centre area, where Mr. Skelos's political operation is circulating fliers reminiscent of Ronald Reagan's 1984 "Morning In America" advertisements.
Although developed primarily for prediction of circulating fluidised-bed combustor operation, the model may be used for other CFB applications.
Theoretical modelling, design and operation of circulating and interconnected fluidized beds require an accurate prediction of solids holdup in the fully developed pneumatic conveying flow regime of the riser (i.e. the upper section of the riser).
This paper analyzes the influences of the hydration heat of cement, heating power, inlet water temperature, circulating water flow velocity, operation mode, and group-pile effects on the heat exchange capacity of CFG pile geothermal exchangers.
Barack Obama's campaign team today accused Hillary Clinton's beleaguered staff of mounting a desperate dirty tricks operation by circulating a picture of him in African dress, feeding into false claims on US websites that he is a Muslim.
In January 2003, Military interrogators at Guantánamo began circulating a "Special Interrogation Operation" document that laid out a plan to subject Slahi to months of extreme isolation, 20-hour interrogation sessions, sleep deprivation, temperature extremes, sexual humiliation, and what would amount to psychological torture.
