Title: Manufacture of lube base stock from Fischer-Tropsch syncrude
Inventor: O'REAR DENNIS J
IPC: C10G2/00
Filed: 2001-11-06
Abstract: A process for manufacturing a lube base stock, and the lube base stock produced by the process, is disclosed. The method involves converting a light hydrocarbon feedstock into syngas, converting the syngas to hydrocarbon products via Fischer-Tropsch synthesis, and isolating a predominantly 650<B>{</B>F<B>-</B> containing fraction (preferably including predominantly C<SB>5-20</SB> hydrocarbons) and a predominantly 650{F+ containing fraction. The 650{F- containing fraction can be converted to distillate fuels, either at the site where the Fischer-Tropsch synthesis occurs, or at a different location. The 650{F+ containing fraction is converted to lube base stocks, preferably at a site different from the site where the Fischer-Tropsch synthesis occurs. Petroleum products with boiling points in the 650{F- or 650{F+ ranges can be blended with the corresponding 650{F- or 650{F+ containing fractions. Portions of the syngas generator, Fischer-Tropsch synthesis reactor and/or equipment used for isolating the 650{F- or 650{F+ containing fractions can be disassembled, transported to another location, and used in the other location. Ideally, the parts can either be reassembled at the other location, or combined with other parts and assembled into a syngas generator, Fischer-Tropsch synthesis reactor and/or equipment for isolating various product fractions.

Title: A method of optimising a quantisation level for compressing a video signal.
Inventor: BOCK ALOIS
IPC: H04N7/26
Filed: 2002-12-20
Abstract: A method of optimising a quantisation level for compressing an input video signal includes performing a transformation on the video signal to a spatial frequency domain to determine coefficients of the transformed signal representative of the video signal and determining a quantisation error introduced with each of a range of quantisation values, operating on the coefficients to determine a selected quantisation value corresponding to a local minimum quantisation error. The selected quantisation value is used for quantisation of the transformed signal to output a compressed video signal. The selected quantisation value may also be used for inverse quantisation of the compressed video signal. An inverse of the spatial frequency domain transform of the inverse quantised compressed signal forms an uncompressed signal and the uncompressed signal is used, together with the input video signal, for motion compensation.

Title: Drilling system and method for controlling equivalent circulating density during drilling of wellbores
Inventor: FONTANA PETER
IPC: E21B47/00
Filed: 2002-07-09
Abstract: A drilling system for drilling subsea wellbores includes a tubing-conveyed drill bit that passes through a subsea wellhead. Surface supplied drillng fluid flows through the tubing, discharges at the drill bit, returns to the wellhead through a wellbore annulus, and flows to the surface via a riser extending from the wellhead. A flow restriction device 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 thereby providing dual gradient drilling while controlling bottomhole pressure and ECD. A controller 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.
