The drill string is hollow so that drilling fluid can be pumped down through it and circulated back up the annulus, creating clearance between the drill string and the casing/open hole (ASME 2011).
As the fluid mixture flows up the annulus, the rates of heat transfer through the drill string and the cement sheath are proportional to the thermal conductivities of the drill string (K_{text{p}}) and the cement sheath (K_{text{c}}), respectively (the thermal conductivity of the casing is assumed to be infinity compared to that of the cement sheath).
BP and government scientists thought that some cement had gone up into the annulus, sealing it off from the reservoir as well, but they were worried that about 1,000 barrels, or roughly 40,000 gallons, of oil might still be trapped in the annulus.

If the operator does not want to delay the start-up of the well to maximize the production, a non-condensable gas such as nitrogen can be injected through the annulus to hasten the gas build-up process.
