Publication number: 20100101473Abstract: The invention relates to a system for loading of hydrocarbons from a floating vessel, such as a FPSO or FSO vessel, to an export tanker, where the floating vessel is spread moored to a sea bottom, and where the export tanker during the loading phase is moored in such a way that the export vessel to a greater or less degree can weathervane dependent upon the prevailing weather, wave and/or wind conditions. According to invention the floating vessel at least at one end is provided with a rotatable deck which can be turned when the heading of the export tanker changes.Type: ApplicationFiled: March 17, 2008Publication date: April 29, 2010Applicant: STATOILHYDRO ASAInventors: Kare G.

Publication number: 20100095757Abstract: Methods and apparatus to measure physical parameters such as density and porosity of the rock matrix in a near wellbore area are provided. A borehole tool having a number of transducer elements in a transducer array is placed at an outermost surface of the borehole tool and is capable of emitting focused high frequency ultrasound beams into the rock matrix in the near wellbore area. The transducer array may be placed on the ribs or stabilizers of the borehole tool, and/or on a sleeve with a lower rotational speed, and may include a fronting material with similar acoustic impedance as the rock matrix.

Publication number: 20100057363Abstract: A method is provided for analyzing data from an electromagnetic survey of a region so as to indicate the presence of a hydrocarbon reservoir. The survey provides vertical magnetic dipole data and electric dipole data, or provides measurement data from which these dipole data may be determined. The amplitude of the vertical magnetic dipole data is determined, optionally after normalising the data with reference date relating to the same region. Similarly, the amplitude of the electric dipole data is determined, optionally after similarly being normalised. The amplitudes are then compared to provide an indication of the likelihood of the presence of hydrocarbons in the region.Type: ApplicationFiled: January 9, 2008Publication date: March 4, 2010Applicant: STATOILHYDRO ASAInventor: Lasse Amundsen

Publication number: 20100045038Abstract: A method for controlling a wind turbine installation for the damping tower oscillations, in particular a buoyant wind turbine installation comprising a buoyant body, a tower arranged over the buoyant body, a generator mounted on the tower that is rotatable in relation to the wind direction and fitted with a wind turbine, and an anchor line arrangement connected to anchors or foundations on the sea bed. The tower oscillations are damped by the control with the blade angle controller in the constant power or RPM range of the wind turbine being performed by the rotor velocity (which is the input to the blade angle controller) being estimated in an estimator for the wind turbine. The input to the wind turbine estimator is the estimated incoming wind, so that the tower movements are not visible to the blade angle controller.Type: ApplicationFiled: August 20, 2007Publication date: February 25, 2010Applicant: STATOILHYDRO ASAInventor: Bjorn Skaare

Publication number: 20090245023Abstract: A method is disclosed for reflection time shift matching a first and a second set of seismic reflection data (10,30) comprising first and second seismic reflection traces (1,3) with series of generally corresponding seismic reflections (11,31). The second set of seismic data (30) comprises at least one laterally extending series (40) of new seismic events (4) not present in the first set of seismic data (10). Reflection time shifts (22) are calculated as required for matching seismic reflections (31) of the second reflection traces (3) of the second seismic reflection data (30) with corresponding seismic reflections (11) of the first reflection traces (1). The calculation of the time shifts (22) are made by calculating coefficients of basis function estimates such as Legendre polynomials in order to save calculation effort.Type: ApplicationFiled: March 31, 2009Publication date: October 1, 2009Applicant: StatoilHydro ASAInventor: Espen Oen LIE
