| 66 | Method of assembly of a string of elements for deepwater drilling and ultradeep obstruction element and corresponding use of the same in said drilling string | US15129346 | 2015-03-13 | US10113379B2 | 2018-10-30 | Angelo Calderoni |
| 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. | ||||||

The drilling system includes a drill string extending into a wellbore, a driver which rotates the drill string, a pump to pump drilling fluid down the drill string, a wellhead mounted at the wellbore, a riser extending up from the wellhead around the drill string, a blowout preventer mounted on the wellhead, a riser closure device mounted in the riser, a first return conduit, and a flow outlet arranged in the riser below the riser closure device. The method includes operating the driver to stop a rotation of the drill string, closing the riser closure device if it is not already closed, operating the pump to stop a pumping of drilling fluid down the drill string, closing the blowout preventer, and increasing a wellbore pressure by controlling a rate of the flow of the fluid along the first return conduit. | ||||||
| 69 | Estimating cuttings removal | US15515050 | 2015-09-18 | US10060209B2 | 2018-08-28 | Morten Lien; André Holm |
| A first property, derivable from mass, of a drilling fluid is measured at a point upstream of a cuttings removal device. A second property (also derivable from mass) is measured at a point downstream of the cuttings removal device. A difference between the properties is determined over a period of time to obtain an estimate of the rate of cuttings removal. This allows the property of the drilling fluid before and after cuttings removal to be compared to give an indication of the rate of cuttings removal, which is indicative of the borehole cleaning. | ||||||

| A method includes pumping fluid into a drill string extending through a riser into a well. A managed pressure drilling system is operated to maintain a selected fluid pressure in the well between the well and the drill string. A fluid influx into the well or a fluid loss into a formation traversed by the well is detected using measurements of fluid pressure in the well and fluid flow into and out of the well. The method includes automatically abating the fluid influx by closing an annular blowout preventer disposed in the riser or abating the fluid loss by operating the annular blowout preventer and pumping a sacrificial fluid into the drill string. | ||||||

| A protection system for a drilling riser. The drilling riser includes a main drilling riser bore and a drilling riser annulus and extends from a floating installation to a location on a seafloor and is fluidly connected to a subsea BOP. The system includes a fluid conduit which extends from the floating installation to a lower region of the drilling riser. The fluid conduit is fluidly connected with the drilling riser annulus in the drilling riser. The fluid conduit provides at least one of a rapid pressure relief and a fluid bypass for the main drilling riser bore to prevent the drilling riser from an uncontrolled pressure build-up due to an inadvertent plugging or a restriction resulting in a maximum allowable working pressure (MAWP) of the drilling riser being exceeded, if a restriction, a plug or a blockage exists in the drilling riser annulus or in riser outlets. | ||||||
