Abstract

The present invention comprises a method for jointly processing data from the nuclear magnetic resonant (NMR) response of oil and rock samples in in natura condition, and its main product is the delimitation of the oil saturation (So) present in the rock samples, i.e., the determination of the range of admissible values of the volumetric fraction of the porous volume of the rock occupied by such fluid. The method requires a small volume of oil, originating from or of a composition similar to the oil present in the rock being tested, since it is based on both the measurement of the NMR response of the rock sample and the response of the fluid sample. These two sets of data feed a statistical inference scheme that (1) determines a range of admissible values for the So of the sample, delimited by the minimum and maximum oil saturation values compatible with the two sets of data presented; (2) produces, for each of these extreme values of admissible So, a decomposition of the rock relaxation time spectrum into two complementary spectra, the first highlighting the signatures relating to oil and the second comprising the distribution of the rock relaxometric signatures that cannot correspond to such fluid under the prescribed saturation condition.

Abstract

The present invention comprises a device and method for non-destructively disconnecting jammed subsea wet-mate connectors. Over time, the inadequate interaction of the housing of these connectors with the cathodic protection of other subsea equipment can promote the accumulation of sediments on the connectors, particularly chalcomagnesian sediments. This layer of sediments is very stable, which sticks the connector and prevents its usual disconnection by means of the mechanical arm of an ROV. The present invention provides a structure comprising hydraulic cylinders that are actuated to move an extractor base, which in turn exerts a force on the subsea connector until the sediment layer is broken and the connector is disconnected. Optionally, the device may actuate a hammer if the hydraulic cylinders fail to break the sediment layer. The hammer causes several impacts that weaken the sediment layer until it is broken, allowing the conventional disconnection of the connector. A method of using the device is also provided. Advantageously, the present invention prevents lifting of the subsea equipment and the destruction of the electrical connector, making disconnection of the jammed connector much faster, more efficient and cheaper.

Abstract

The present invention discloses a device and a method for inspecting furnace catalyst tubes. The device comprises two eddy current sensors consisting of an eddy current excitation coil and a Hall effect sensor, wherein the second of these sensors also includes a yoke where permanent magnets are positioned on its sides. The permanent magnets cause an external surface layer of oxides on the surface of the tubes to be magnetically saturated, allowing the eddy currents generated by the second sensor to penetrate the interior of the tube wall. In this way, eddy current data are obtained from the interior of the tube wall by the second sensor and from the tube surface by the first sensor. These data are processed by an analyzing element that incorporates an artificial intelligence previously trained to determine the aging state of the tube based on the data obtained by the sensors. In this way, a non-destructive and real-time analysis of the aging state of the tube is achieved. The hybrid probe can be used manually to determine the aging state of a specific point on a tube or in automated inspection, in which an autonomous mobile device guides the probe along the tube, allowing real-time determination of the longitudinal profile of the aging states.

Abstract

The invention consists of a system comprising an emitting PCB 10 and one or more receiving PCBs 10, each PCB comprising three coils. The one or more receiving PCBs 10 are positioned on pavement layers while the pavement is being prepared. After the pavement is complete, tests are performed to cause deformations in the pavement. The emitting PCB 10 is positioned on the pavement surface so as to form a pair with one of the receiving PCBs 10. A signal is emitted by a signal generator 20 to the emitting PCB 10, inducing a magnetic field in its coils, which in turn is captured by the coils of the receiving PCB 10 of the pair. The signal resulting in the receiving PCB 10 is captured by a signal receiver 20 that determines the coupling between the pair of PCBs 10. Based on previous calibrations, it is possible to determine the distance between the pair of PCBs after the tests based on the determined coupling. Since the distance before the tests is known, it is possible to determine the new position of the receiving PCB 10 and, consequently, the deformation suffered by the layer where the receiving PCB 10 is located and the contribution of this layer to the total deformation of the pavement. Furthermore, the use of the set of three coils allows an estimate of any horizontal displacements or rotations that may occur between the pavement layers.

Abstract

Embodiments of the equipment described herein uses lasers stabilized in the resonant optical cavities of Fabry-Perot Interferometers (FPIs), with at least one reference interferometer, in order to cancel the effects of atmospheric variation in the measurement of the variation of the gravitational acceleration. In addition, the radio frequency used in the modulators, or the frequency beat of the independent lasers, allows the measurement of the variation of “g” directly in the variable “frequency”, which allows high-precision measurements due to the existence of accurate clocks in counters/frequency meters. In short, the gravimeter comprises a high-finesse Fabry-Perot interferometer-based sensor with fast reading time, does not require high vacuum in the chamber thereof, can be operated in motion and can be subjected to very high pressures, without an extra encapsulation, and requires low electrical power for operation, and makes gravity measurements directly in frequency.

A torque application system for use in mechanical circuits and offset flanges is described. More precisely, the system of the invention comprises a set of elements that apply torque to the region of offset flanges capable of eliminating gaps in closed mechanical systems, wherein this set of components responsible for applying torque, in addition to promoting permanent contact of the mechanical system, allows a previously known load to be imposed. Accordingly, the system described herein allows analysis cycles to be achieved under different operating conditions that require smoothness, given the more uniform behavior of the mechanical system under analysis. Furthermore, due to internal load compensation means, the torque application system prevents overloads in the mechanical system, since compensating means provided with springs compensate for possible misalignments that could result in permanent plastic deformations in the elements to which the set of components of the torque applicator is coupled.

Abstract

The present invention comprises a computer-implemented method for automating the co-registration of SEM and 3D microtomography images in rock sample cylinders, characterized by comprising three main steps: (i) image pre-processing; (ii) internal orthogonal search; (iii) external multi-angle search. The method plays a fundamental role in the creation of image pairs. These pairs capture the same region of the rock, but with different analytical properties. Thus, the co-registration between 2D microscopy and 3D tomographic data provides a fundamental basis for the application of machine learning techniques and the expansion of the originally planar mineralogy to the entire three-dimensional volume. The three-dimensional mineralogical model generated from this co-registration has fundamental implications for the creation of digital rock models. The automation of the co-registration process between these acquisitions contributes to the advancement of petroleum engineering, since co-registration accelerates the process of generating image pairs for the use of machine learning algorithms in the generation of the three-dimensional mineralogical model. This method, in its turn, has direct application both in oil reservoir engineering and in geological interpretation.

Abstract

The present invention relates to a machine learning unsupervised method to improve results obtained in electro-facies models. In this method it is possible to subdivide profile data into different unsupervised classes interactively and intuitively based on rock data information, seeking not only to meet the need to respect profile data values, but also to represent the geological knowledge that exists in the labeled data which serves as a guide in decision making to define which classes should be subdivided or attached. In the method, the result is constructed little by little and intuitively, just like the process of analyzing an outcrop or core. Initially, profile data is used to identify the most relevant and easily separable macro characteristics, such as reservoir and non-reservoir rock. Additionally, there is the possibility of interactively subdividing or attaching classes to test scenarios and quickly validate concepts. In this sense, it is quite intuitive to start from a macro analysis and gradually identify more specific characteristics based on the geological knowledge of a specialist or what the rock data indicates, so that the method allows countless interactions to be carried out until reaching the desired result.

Abstract

The present invention relates to the coprocessing of liquid plant biomass of lignocellulosic origin and residual fractions from petroleum distillation, in which the injection of the renewable charge is carried out through the top of the coker, avoiding the problems of accelerated coking in the oven tubes and obstructions in the unit lines which inevitably occur when this type of renewable charge is coprocessed in a mixture with the main (fossil) charge. In the present invention, the renewable material is injected through the top of the reactor, in conjunction with an accelerating gas, by means of a suitable injector, so as to minimize the possibility of obstruction of the system during injection. Due to the physical and chemical characteristics of lignocellulosic charges, the addition of this type of charge through the top of the reactor could also lead to difficulties related to the possibility of obstruction of the line in the reactor inlet, since the usual top temperature inside such reactors is around 440°C. In order to overcome this technical problem, the present invention proposes using an auxiliary charging system for injecting bio-oil and a gas stream, comprising a tank, a pump and a charging injector. The injection system of the present invention promotes increased speed, cooling and improved dispersion of the renewable charge in the inlet of the reactor.
