Title: Interventionless multi-position frac tool
Inventor: XU YANG
IPC: E21B43/26
Filed: 2008-08-18
Abstract: Fracturing tools for use in oil and gas wells are disclosed. The fracturing tools have a run-in position and two operational positions. A sleeve disposed in the bore of the fracturing tool comprises a sleeve port alignable with a first port in the housing of the frac tool, i.e., the first operational position, during fracturing operations. A second port having a restriction member is disposed in the housing and is closed by the sleeve during fracturing operations. After fracturing operations are completed, a return member in the frac tool moves the sleeve from the first operational position to a second operational position for production operations. In this second operational position, the first port is closed and the sleeve port is aligned with the second port. Movement of the sleeve from the first operational position to the second operational position is performed without the need for an additional well intervention step.

Title: Apparatus for steerable drilling of a borehole using hydrostatic bearings
Inventor: SIHLER JOACHIM
IPC: E21B7/06
Filed: 2007-10-25
Abstract: Hydrostatic bearings are used for drill string stabilization and bottom hole assembly steering The hydrostatic bearings 200 utilize an existing mud flow as the bearing fluid. For steering, the bearings may be used between movable kick pads (1200, Fig 12) and the formation to reduce friction. Alternatively, differential hydrostatic bearing pressure may be utilized to steer. Multi-modal, that is non-linear and linear steering, may be provided by selectively applying equal and unequal hydrostatic bearing pressures. The bearings can be made more tolerant of imperfections in the formation by utilizing multiple pressure pockets.

Title: Frequency scanning antenna with elements radiating different signal power
Inventor: FOCKE THOMAS
IPC: G01S13/00
Filed: 2010-12-24
Abstract: An antenna, suitable for radiating a signal in a direction in space dependent on the frequency of the signal, comprises an antenna body with a dielectric material and signal line 200 located between two parallel conductive ground surfaces and a plurality of aperture antenna elements 300 arranged in a straight line in one of the conductive ground surfaces. The line of aperture antenna elements 300 are arranged above the signal line 200 and at least two of the antenna elements 300 differ from one another such that they radiate with different power. The central antenna elements 340 may be large whilst the antenna elements 300 get smaller the further they are from the central antenna elements 340. The radiated beam signal power distribution may be used to reduce the level of side lobes. The signal line 200 may be a serpentine waveguide or strip line conductor with structures compensating for the signal disturbances caused by the antenna elements. The antenna may include a segment of a cylindrical lens made of polyetherimide to focus and increase the gain of the antenna beam. Various antenna element arrangements are described which may be used to adjust the radiated beam from the antenna.

Title: Receiver noise compensation
Inventor: YOUNG ROBERT
IPC: H03D3/00
Filed: 2011-12-23
Abstract: A method for estimating an unwanted component (noise) that a receiver introduces into a received signal (201, Figure 2) at a known frequency, the method comprising applying a frequency offset to a signal 102, which comprises a wanted component at the known frequency, to form an offset signal having a frequency spectrum (302, Figure 3) in which the wanted component is not positioned at the known frequency, processing the offset signal in the receiver 103 and estimating a component positioned at the known frequency in the frequency spectrum of the processed signal 104. The estimated component will correspond to the unwanted component, for example at DC, introduced by processing the signal at the receiver. This estimated unwanted component can therefore be estimated and removed, i.e. subtracted, from the processed received signal 105. The method in one embodiment therefore provides a DC offset estimation and compensation arrangement. The frequency offset may be applied at the receiver or at the transmitter. The signal may comprise a synchronization portion (202, Figure 2) consisting of a series (206, Figure 2) of identical repeated blocks (207, Figure 2) and in one embodiment only the synchronization portion is frequency offset. The synchronization portion may have a frequency spectrum (301, Figure 3) comprising a plurality of equally spaced peaks and the frequency offset may be set to be equal to an odd-multiple half of the spacing between two of the peaks. The frequency offset may be reversed once the estimated unwanted component has been removed from the signal. The unwanted component introduced by the receiver may be due to a number of factors such as noise or offset introduced from amplification, mixing or filtering etc. stages.

Title: Image process with spatial periodicity measure
Inventor: KNEE MICHAEL JAMES
IPC: H04N5/14
Filed: 2012-09-25
Abstract: An image manipulation process, such as interpolation of an image in a sequence, depends on a spatial periodicity measure for image data that is a function of the sparseness of the two-dimensional spatial frequency spectrum of the processed image data. At least one two-dimensional (2D) block of image data may be processed in a two-dimensional Fourier or other spatial to frequency domain transform and preferably the periodicity measure is evaluated from the portion of the transformed image data representing AC spectrum components. Sparseness may be a linear function of the mean-square value and the square of the mean value of transformed image data for the 2D block; sparseness can further depend on the mean-square value of low spatial frequency transform output values. Sparseness can be a count of the number of spatial frequency values exceeding a threshold, and may be measured by allocating spectrum values to frequency bins, counting the number of non-zero values. The spatial periodicity measure may be normalised, divided by a function of the mean-squared image data. A two-dimensional spatial frequency spectrum having all equal values has zero sparseness; a spectrum having only one non-zero value has a unity sparseness.
