  • Patent number: 10358912
    Abstract: Fluid tube for sealing test in a BOP chamber. The test tube used in the BOP chamber resistance test step has its hollow structure filled internally and totally through a fluid input. The tube obtains an effective sealing due to the filling fluid volume that exhausts the air within it, stopped internally with the couplings of screwed pin threads and a female thread of a plug or test plug, preventing the test fluid into the chamber to leak and enter the hollow structure of the chamber. The supplementary structure anti-distortion system including air absence inside the tube and test tube stoppage the system avoids false pressure into the chamber to the sensors distributed therein, not detecting false leakages, making the BOP resistance analysis against potential oil/gas leakages precise during the probing procedure.

  • Patent number: 10353111
    Abstract: Disclosed systems and methods provide automated log quality monitoring, thereby enabling fast, on-site determination of log quality by logging engineers as well as re-assurance to interpreters faced with geologically-improbable features in the logs. Such uses can provide early detection of logging issues, increase confidence in acquired logs, reduce unnecessary duplication of effort, and improve the reputation of the logging company. In at least some embodiments, log monitoring software applies a comparison function to axially-spaced (and/or azimuthally-spaced) sensors. The comparison function can be, inter alia, cross-correlation, mutual information, mean-square error, and ratio image uniformity, each of which can be determined as a function of a sliding window position to indicate regions wherein the log quality falls below a threshold value. It is not necessary for the log sensors to be of the same type, e.g., resistivity image sensors.

  • Patent number: 9086506
    Abstract: Maximum and minimum horizontal stresses, and horizontal to overburden stress ratio, are estimated using radial profiles of shear moduli. Inversion enables estimation of maximum and minimum horizontal stresses using radial profiles of three shear moduli associated with an orthogonal set of axes defined by the three principal stress directions. Differences in the far-field shear moduli are inverted together with two difference equations obtained from the radial profiles of the dipole shear moduli C44 and C55, and borehole stresses in the near-wellbore region. The horizontal to overburden stress ratio is estimated using differences in the compressional, dipole shear, and Stoneley shear slownesses at two depths in the same lithology interval where the formation exhibits azimuthal isotropy in cross-dipole dispersions, implying that horizontal stresses are nearly the same at all azimuths.

  • Publication number: 20130180327
    Abstract: A method of modelling a hydrocarbon-containing reservoir which is representative of such reservoir in at least one physical characteristic such as reservoir porosity or permeability. Data, such as reservoir porosity is firstly determined. Such data is then transformed into printing instructions for a 3D printer. The 3D printer is used to print a reduced-scale model which is representative of the reservoir in respect of the at least one physical characteristic, such as reservoir porosity. A method of comparative testing of different hydrocarbon recovery techniques on a single hydrocarbon-containing reservoir is also disclosed and claimed.

  • Publication number: 20130036812
    Abstract: The invention relates to a method and an apparatus for detecting tightness of threaded joints of drill rods when unfastening at least one threaded joint of the drilling equipment (6) by impacting the drilling equipment (6) with a percussion device in the rock drilling rig (1). For detecting the tightness there is predetermined at least one fastened model for a situation where the threaded joint/joints are fastened, a vibration signal measured during impacting is compared with both the fastened model and the unfastened model and, on the basis of the comparison, it is determined to which one of the models the tightness of the threaded joints better corresponds at the moment of determination.

  • Publication number: 20130020075
    Abstract: Hydraulic fracturing, acidizing and polymer injection using coiled tubing are commonly used techniques in wellbore completion. A pulsed neutron tool may be conveyed at the bottom of the coiled tubing to monitor the effectiveness of these operations by measuring the flow velocity of the borehole fluid of the annulus between the pulsed neutron tool and the borehole wall. Gamma rays resulting from Oxygen activation and/or ? measurements are used for measuring the flow velocity.

  • Patent number: 8126650
    Abstract: Method for efficient inversion of controlled-source electromagnetic survey data to obtain a resistivity model of the subsurface of the survey area. The method extracts the dimensions and location of sub-surface structures as they may be revealed by existing seismic or other available high resolution survey data from the subsurface area (33). This structure geometry information is used to construct a discretization (grid, or mesh) for the inversion computation (34) that is different from the mesh used for the forward modeling calculations (32) in that (a) it has fewer and hence larger cells; and (b) the cells honor the assumed structural information. The inversion need only extract resistivity information (35), the geometry of the resistive structures being specified by the inversion mesh.
