Abstract: A process for overcoming aliasing using a minimum weighted norm interpolation (MWNI) technique may include computing an initial, regularly interpolated model with no data gaps and computing a plurality of initial spectral weights using the initial, regularly interpolated model. The initial, regularly interpolated model is used to compute the spectral weights as initial constraints in a least-squares solution methodology. The initial spectral weights are used as initial constraints in a constrained minimum weighted norm interpolation data reconstruction. The process may further include converting the initial, regularly interpolated model into a frequency domain and computing unknown spectral weights from frequency data at each frequency slice of the initial, regularly interpolated model using Fourier transform. The process results in reducing aliasing artifacts and improving data regularization.

Abstract: Methods and apparatus relate to measuring corrosion rate. Flowing corrosive fluid contacts a metal coupon or object and results in an effluent stream. The effluent stream contains metal from the object due to reaction of constituents in the fluid with the metal. Analysis of the effluent stream measures concentration of the metal therein. Since the concentration of the metal in the effluent stream is indicative of mass loss from the object, calculations provide the corrosion rate utilizing weight of the metal that is eluted, surface area of the object and exposure time of the object with the corrosive fluid.

Abstract: Methods and systems relate to steam assisted gravity drainage (SAGD) utilizing well pairs that are at least initially in fluid communication through drilled bores toward their toe ends. At least one of a horizontal injection well and horizontal production well of such a well pair includes a hooked length toward toe ends of each other connecting said injection well and said production well.

Abstract: Methods for recovery of heavy oils use selective catalytic downhole upgrading with SAGD technology. Certain embodiments include extracting heavy oil using a SAGD process and upgrading the heavy oil in a production well with a cracking catalyst. The cracking catalyst is introduced into the production well, allowing the extracted hydrocarbons to interface with the cracking catalyst to upgrade the hydrocarbons. The upgraded hydrocarbons are then separated from the cracking catalyst. This upgraded stream has a lower molecular weight, significantly reducing the viscosity of the produced hydrocarbons. A gasifier is provided to gasify a portion of the slurry containing unconverted heavy oil and cracking catalyst to produce syngas. The syngas may then be used to produce steam for use in the SAGD extraction process, improving energy efficiency of the process. Further, formation catalyst losses are avoided as the catalyst injected into the well is recovered and available for reuse.

Abstract: Embodiments relate to methods and systems for loading a liquid solvent with a gas. Upon spraying the solvent into contact with the gas, droplets of the solvent absorb the gas and coalesce as a partial loaded solution. The solution then passes along at least one wetted wall column disposed in contact with the gas for further loading of the solvent. One exemplary application utilizes an amine as the solvent to be loaded with the gas, such as carbon dioxide.

Abstract: Drilling a sidetrack wellbore out of the side of an existing wellbore utilizing a drillable billet having a path formed in the billet to lead a bi-centered drillbit to kick-out from the wellbore and form a sidetrack wellbore. The bi-centered bit is arranged for the lands of the pilot section to follow the path of the billet while the wings of the ream out a portion of the billet and also ream out the earth to form the full dimension sidetrack wellbore. The bi-centered bit is used to drill the sidetrack wellbore to the target zone so that the entire drilling process extends from the existing wellbore to the target zone without a mandatory withdrawal of the drillstring from the wellbore.
