Abstract: Downhole properties of a geological formation may be determined using nuclear magnetic resonance (NMR) measurements obtained by a moving tool. To do so, an interpretation of the NMR data obtained by the moving data may take into account a moving model, characterization, or calibration of the downhole NMR tool. Additionally or alternatively, a partial interpretation mask may exclude interpretation of certain areas of data (e.g., T1-T2 data points or diffusion-T2 data points) that are expected to be less likely to describe downhole materials of interest.

Abstract: The invention relates to a device (100) for testing a connection of a guarantee strip (3.1) of a security seal of a closure lid (1.1) having a lid main body (2.1), which device comprises a driver element (180) for gripping the guarantee strip (3.1) and a stop element (780) for the lid main body (2.1). The driver element (180) and the stop element (170) are movable relative to each other such that a tear-off force can be exerted on the guarantee strip (3.1). The device (100) also comprises a force-measuring device (171), for measuring the tear-off force during the relative movement of the guarantee strip (3.1) and the lid main body (2.1), and a separating device (191, 192) for severing the guarantee strip (3.1) after it has been tom off from the lid main body (2.1). This allows the guarantee strip (3.1) to be severed and thereby results in a considerable simplification of the removal of the guarantee strip (3.

The small-sized flowlines can have a channel with an inner diameter or maximum width of less than 0.2 inch and can be made of sapphire, yttria-stabilized zirconia (YSZ), or extruded polyether ether ketone (PEEK), which are useful in high temperature, high pressure environments such as downhole in a geological formation.

Abstract: Apparatus and methods are provided for finding indications of at least one of a water fraction, a hydrocarbon fraction, water conductivity, and water salinity of a fluid. The fluid is within a flow line that extends through a resonator. The flow line is subjected to microwaves at multiple microwave frequencies injected into the resonator, with electric field lines parallel to the fluid flow line. A power detector is used at an output of the resonator, and a peak power and associated resonance frequency are used to find the indication(s) which may be plotted and displayed. In one embodiment, the resonator is a dual loop-gap resonator, and the microwave frequencies are generated by a microwave sweeper source at approximately 1 GHz.

Abstract: Methods are provided for identifying one or more transition characteristics in a hydrocarbon fluid such as asphaltene onset pressure (AOP), bubble point or dew point. A transition characteristic is determined by subjecting the fluid to different pressures or temperatures, conducting NMR tests at the different pressures or temperatures to obtain signals, processing the signals to obtain values of a function of an NMR parameter as a function of pressure or temperature, and analyzing the values to find a discontinuity that identifies the transition characteristic. In embodiments, the NMR parameters may include at least one of a relaxation parameter such as T2 or a T1-T2 ratio, a diffusion parameter and an initial magnetization parameter. In embodiments, dual linear fitting, Bayesian change point detection algorithms, and instantaneous slope analysis may be utilized to analyze the values in order to find a discontinuity.
