| A drillstring terminating in a drill bit is run into a borehole. A reduced solid content drilling fluid is pumped through the drillstring and out the bit, wherein the drilling fluid impinges upon and disintegrates formation material in cooperation with the bit. An annulus fluid having a density greater than that of the drilling fluid is continuously pumped into the annulus between the borehole and drillstring, wherein the annulus fluid extends substantially from the surface to the bottom of the drillstring. Drilling fluid and cuttings resulting from disintegration of formation material are returned to the surface through a substantially unobstructed tubular passage in the drillstring. The annulus fluid is maintained under a selected and controlled pressure in the annulus, wherein an interface is formed at the drill bit at which annulus fluid mixes with the drilling fluid and is returned along with the drilling fluid and cuttings and drilling fluid is substantially prevented from entering the annulus. | ||||||

| A method of assembly is for a string of drilling elements for deepwater drilling. Each drilling element includes an axial through hole, through which drilling mud can flow, and two connection portions for connecting it in series in the string. The method includes assembling a lower portion of the string, assembling a first drilling element with other drilling devices to create a first section of the string. These steps are repeated until the lower portion is proximate the blowout preventer or the bottom. Assembly of second drilling elements begins while executing a drilling cycle for creating at least a second section of the string. The assembly step is repeated until the second section extends equal to a desired drilling depth. After assembling the lower portion and before assembling the first drilling element, a third drilling element is assembled, which includes an obstruction element for preventing backflow in the string. | ||||||
