Abstract: A subsea equipment-protection apparatus including: a cap (1) and a sleeve (2), wherein the cap and the sleeve are configured to be supportable by a foundation (6) of the subsea equipment (16). The cap and the sleeve are arranged such that at least a portion of the cap may enter an opening of the sleeve and be supported by the sleeve; and thereby the cap and sleeve cover and protect the subsea equipment.

Abstract: There is described subsea apparatus and a method for processing fluid from a well. In an embodiment, a pipeline may be arranged to carry the multiphase fluid containing liquid and gas from the well. An outlet extending through a wall of the pipeline may let gas out of the pipeline from said region and through the outlet to separate said gas and liquid. A compressor may be connected to the outlet to compress the separated gas. Separated liquid may be conveyed along a sloping portion of the pipe to a low point in the seabed terrain, and may be conveyed to a pump for boosting the flow of liquid. The pump may be located in an excavated hole or glory hole below the seabed.

Abstract: The present invention relates to a method of processing seismic data. The method may include calculating a number of calculated structure tensors for each of a number of seismic data lines, the seismic data lines being spatially distributed about an area of the surface of the Earth. The method also may include interpolating the calculated structure tensors to find interpolated structure tensors in a region of the area between the lines of the seismic data lines, and calculating calculated seismic data from the interpolated structure tensors.

Abstract: 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.

Abstract: A method of plugging a well extending into a hydrocarbon bearing formation fascilitates temporary or permanent abandonment of the well. The method includes detonating one or more explosive charges within a tubular or tubulars extending through the well in order to remove, fragment and or cut one or more sections of the tubulars around the entire circumference of the well to expose the surrounding formation or cement. The well is then filled in the region of the exposed surrounding formation or cement with a sealing material so as to form one or more plugs within the well to seal the well.

Abstract: A method for use in surveying a subsurface region beneath a body of water by detecting S waves propagating through the subsurface region. The method comprises using a first sensor configuration to detect mixed S and P waves on or in the subsurface region, using a second sensor configuration located on or in relatively close proximity to the subsurface region to detect P waves in the water, and using the P waves detected in the water to compensate the detected mixed S and P waves, and thereby attenuate the effects of P waves in the mixed S and P waves.
