Abstract: The present invention provides for a method and apparatus for seismic data processing. Prestack seismic data is obtained that contains a plurality of reflectors. Non-parallel moveout of the plurality of reflectors is utilized to determine a source wavelet using an L2-Norm and a reflectivity parameter using an L1-Norm. The source wavelet and reflectivity parameters can be determined simultaneously. Source and reflectivity determination may further comprise minimization of a model objective function. The model objective function may be a function of at least one of i) said source wavelet, ii) a gradient parameter and iii) an intercept parameter. An AVO intercept and gradient parameters can be determined using the determined source wavelet and reflectivity parameter. Constraints may be placed on parameters to ensure physically realistic solutions.

Abstract: The present invention is a method for determining a parameter of interest of a region of interest of the earth. At least one component of potential fields data is measured at a plurality of locations over a region of interest including a subterranean formation of interest. The potential fields data are selected from magnetic data and gravity data. An initial geophysical model is determined for the region including the subterranean formation of interest. For the model, geophysical tensor data is updated using a forward model at a plurality of locations using a High Order Compact Finite Difference method. A difference between the estimated model value and the measured value of the potential field measurements are determined, and the geophysical model is updated. The model is iteratively updated and compared to the measured data until the differences reach an acceptable level and the parameter of interest has been determined.

Abstract: A method of optimizing production of a hydrocarbon-containing reservoir by measuring low-frequency Distributed Acoustic Sensing (LFDAS) data in the well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow and simultaneously measuring Distributed Temperature Sensing (DTS) data from the well during a time period of constant flow and during a time period of no flow and during a time period of perturbation of flow. An initial model of reservoir flow is provided using the LFDAS and DTS data; the LFDAS and DTS data inverted using Markov chain Monte Carlo method to provide an optimized reservoir model, and that optimized profile utilized to manage hydrocarbon production from the well and other asset wells.

Abstract: Gravity driven reverse circulator tools are provided and methods of using same. One tool has nested pipes that when fully nested close a hole in one of the pipes, but when the drillstring is lifted, the pipes partially separate under the force of gravity to expose the hole. The other embodiment is similar, but the hole is hook shaped (hook on top as in a walking cane) and a protrusion from the other pipe fits in the hole. Thus, both lifting and rotation are needed open the tool.

Abstract: The invention relates to a method and system for monitoring strain data on a subsea wellhead and associated tubing especially during a drilling or completion operation when the wellhead is connected via a riser to a drilling rig. The bending stresses on the wellhead assembly can be modelled and monitored, based on strain data from strain gauges attached to the conductor, surface casing and possibly also inner tubing. The strain gauges are located where maximum bending stresses occur, at around seafloor level. Data from the strain gauges is transmitted by radio to a receiver unit on the template, from which it may either be transmitted to the surface or stored and retrieved by divers or subsea vehicles.
