Abstract: A method of determining an optimal flare spacing for streamers towed behind a seismic vessel comprising the steps of: using a computer specially adapted with a seismic data analysis package to analyze prior seismic data for a survey area; analyzing migration broadcast patterns to estimate a maximum sampling distance; calculating a wavelet expansion as a function of flare spacing; creating synthetic gaps in the prior seismic data coverage by dropping traces at different flare spacing; testing capability of different interpolation algorithms in the seismic data analysis package to close the synthetic gaps; and determining an optimal flare spacing based upon the capability of the different interpolation algorithms to close the synthetic gaps.

Abstract: The invention relates to the introduction of pressurized fluid, e.g. acid, into a subsea well directly from a vessel (33). A fluid injection assembly (20) is fitted to the top of a subsea Xmas tree (3), the assembly (20) including fail safe closed valve (21) which is controlled via a hydraulic line (31) from the vessel. The hose and assembly and valve are designed with an internal bore allowing a large diameter ball to be dropped (required for acid stimulation). The subsea subsea control module (8) on the Xmas tree is controlled from the producing platform.

Abstract: Systems and method for nuclear magnetic resonance (NMR) well logging use an inversion pulse sequence with a Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence to improve spin magnetization calculations. Improved Bloch equation-based calculations consider conditions where a longitudinal relaxation time and a transverse relaxation time of the hydrogen nuclei (e.g., of a subterranean hydrocarbon pool and/or water) are within an order of magnitude of pulse durations for the inversion pulse sequence and the CPMG pulse sequence. Accordingly, an NMR response to the inversion pulse sequence and the CPMG pulse can be detected and used to calculate one or more spin magnetization values with higher accuracy amplitudes. Reservoir characteristics are determined based on the one or more spin magnetization values. As such, improved well operations (e.g., selecting a drilling site, determining a drilling depth, and the like) can be performed.

Abstract: The invention relates to a method of conducting a perf wash cement (“P/W/C”) abandonment job in an offshore oil or gas well annulus (2), in particular the washing or cementing operation using a rotating head (6, 8) with nozzles (7, 9) dispensing wash fluid or cement at pressure. Certain values of parameters of a washing or cementing job have been found surprisingly to affect the quality of the job, or the degree to which they affect the quality of the job has been unexpected. These include including rotation rate of the tool, the direction of translational movement of the tool, and the volume flow rate and pressure per nozzle of cement or wash fluid (and hence nozzle size).

Abstract: A steam-assisted gravity drainage method is described that includes a two stage solvent injection scheme, wherein steam plus solvent injection is followed by steam plus heavier-solvent injection. The two solvent injections improve recoveries of both the heavy oil and the injected solvent while limiting steam requirements, thus improving the economics of the method.

Abstract: The invention relates to the treatment of wastewater on an offshore hydrocarbon producing rig, where the wastewater is from a variety of sources and has variable content but always includes both oil and particulates. A cross flow membrane filter removes oil whilst dead end type pre-filters are provided to remove particulates which would otherwise quickly erode the membrane filter.

Abstract: A method for obtaining a natural gas liquid (NGL) product from a liquefied natural gas (LNG) liquefaction facility including receiving a gas feed stream at an LNG facility having an NGL recovery unit integrated therein, cooling the gas feed stream via a demethanizer of the NGL recovery unit to separate a vapor from a liquid, transferring the vapor from the NGL recovery unit to an LNG liquefaction unit and transferring the liquid to a deethanizer within the NGL recovery unit for further cooling, and obtaining an ethane product and an NGL product from the cooled liquid.

Abstract: This disclosure describes a device and method of sealing perforations on a well casing inside a subterranean well. The device comprises a generally cylindrical sleeve having an open top and a closed bottom; a heater located inside the sleeve, the heater comprising a thermite mixture; an ignition mechanism that ignites the thermite mixture upon actuation; and a string connected to the heater ignition and detachably engages the sleeve. The method comprises lowering a body of meltable plugging material into the well casing near the perforations; lowering the plugging device into the well casing immediately on top of the body of meltable plugging material; melting the meltable plugging material by igniting the thermite thereby transferring heat to the body of meltable plugging material; forcing the molten plugging material into the perforations by pushing the plugging tool further downhole; cooling the plugging tool and the plugging material until the plugging material solidifies; disengaging the tubing string from the sleeve and retrieving the tubing string with the heater; and removing the sleeve and bismuth remaining in the well casing, but not in the perforations.
