Abstract: A drilling system for drilling subsea wellbores includes a tubing-conveyed drill bit (130) that passes through a subsea wellhead. Surface supplied drillng fluid flows through the tubing (121), discharges at the drill bit, returns to the wellhead through a wellbore annulus (122), and flows to the surface via a riser extending from the wellhead. A flow restriction device (164) positioned in the riser restricts the flow of the returning fluid while an active fluid device controllably discharges fluid from a location below to just above the flow restriction device in the riser, thereby controlling bottomhole pressure and equivalent circulating density ("ECD"). Alternatively, the fluid is discharged into a separate return line (206) thereby providing dual gradient drilling while controlling bottomhole pressure and ECD. A controller (180) controls the energy and thus the speed of the pump in response to downhole measurement(s) to maintain the ECD at a predetermined value or within a predetermined range.

Abstract: A system and methods of transmitting information between a first location and a second location comprise transmitting a data signal and a known signal from one of the first location and the second location over a signal channel having a first noise component. A second noise component is measured in a noise channel adjacent the signal channel. The data signal, the known signal, and the first noise component are received at the other location. The first noise component is estimated based on the second noise component. The estimated noise component is combined with the received data signal and the received known signal to generate noise-cancelled received data and received known signals. The noise-cancelled received known signal is processed to obtain an estimate of the channel transfer function. The estimated channel transfer function is combined with the noise-cancelled received data signal to reconstruct the transmitted data signal.

Abstract: A wellbore system and method for producing seismic waves in an earth formation. The system comprises a cavity containing fluid. The cavity is in a space between a wellbore tubular, which may be casing or production tubing, and the wellbore formation. A device is provided for generating pressure waves in the cavity at resonance frequencies of the cavity. The pressure waves generate seismic waves that radiate into the adjacent earth formation that may be recorded. The recorded seismic waves may be used to determine parameters of interest of the earth formation.
