Abstract: Computer-implemented systems and methods are disclosed for automatically generating and displaying a chronology of events, where events may be represented by data objects in one or more databases. Events/data objects may be identified as relevant to an investigation or analysis based on specified criteria. A timeline may be generated based on the identified set of relevant events, and interactive user interfaces may be generated and displayed that present the events as a timeline and a list. Events may be selected from the timeline or the list, may be identified as key events in the chronology, and additional events related to a selected event may be determined and added to the chronology. Timelines may be compared to other data sets, including other timelines, other event lists, and other relevant data.

Abstract: Techniques for calculating metrics for reservoir quality based on light oil and total organic carbon in tight oil reservoirs are described.

Abstract: A remote seal assembly for a process transmitter includes a seal body containing a cavity sealed by a diaphragm. The seal body configured to be mounted to a process element containing a process fluid such that a first side of the diaphragm is exposed to the process fluid. A capillary contains a fill fluid that is in fluid communication with the cavity and a second side of the diaphragm. A coupling has a capillary recess and two cavities separated by a second diaphragm. The capillary extends through the capillary recess and connects to the coupling such that the fill fluid in the capillary is in fluid communication with one of the two cavities and the second diaphragm. A thermally conductive element preferably extends continuously along the capillary from the seal body toward the coupling and into the capillary recess without contacting the coupling.

A process coupling couples the pressure sensor to the industrial process using an elongate housing with a fill fluid capillary. In one example configuration, at least one thermoelectric element is included within the elongate housing to apply heat to, or conduct heat away from, the process coupling in response to an applied electric current or signal, allowing fill fluid to be preheated to facilitate cold startup or calibration, and providing cooling of the process coupling during high temperature operation.

Abstract: A pressure transmitter assembly for measuring a process pressure of an industrial process includes a pressure sensor configured to sense the process pressure. A process coupling couples the pressure sensor to the industrial process. In one example configuration, a phase change material carried in the process coupling is configured to reduce heat transfer from the industrial process to the process variable sensor by changing phase in response to heat from the industrial process. In another example configuration, a thermocouple electric cooling element is coupled to the process coupling and configured to conduct heat away from the coupling in response to an applied electric current.

Abstract: The invention generally relates to switch mode power converters (SMPCs).

Abstract: A controller for use in a power converter includes a first terminal to provide a turn on signal to initiate turning on of a power switch and a second terminal to provide a turn off signal to initiate turning off the power switch. A detection circuit is coupled to detect a turn off time delay. The turn off time delay is the duration of time between an initiating of a turn off of the power switch by the turn off signal and an actual turn off of the power switch. A control circuit is coupled to control the turn on signal to regulate the turn off delay time to a target time value. The control circuit controls the turn on signal by controlling an amount of charge delivered to turn on the power switch.

Abstract: A switch mode power converter (SMPC) includes a switching control system to control the turn off time delay of a switching device. The SMPC also has an inductive component including an input winding to receive power from an input and a switching device to conduct input winding current. The switching control system applies turn on and turn off signals to the switching device. The turn off signal initiates turning off of the switching device and a sensing signal from a further winding inductively coupled to the input winding is detected to indicate an end of a turn off time delay or duration. The turn on signal for a subsequent switching cycle of the SMPC device is controlled to regulate the turn off delay time.

Abstract: Techniques for quantifying minerals in a formation sample include using a joint inversion of DRIFTS (diffuse reflectance infrared Fourier transform spectroscopy) spectra and XRF (X-ray fluorescence) data. This joint inversion produces quantification of additional minerals (e.g. pyrite and barite) than those quantified by the individual inversion method (DRIFTS-only). The method is applied to oilfield reservoir samples and the mineralogy solution is compared to the DRIFTS-only solution and to mineralogy estimated from benchmark FTIR (transmission Fourier transform infrared spectroscopy) method.

Abstract: Levels of kerogen and bitumen are computed in a sample of rock from DRIFTS measurements on the sample. the DRIFTS spectrum of a rock sample is measured, resulting in an estimate of bitumen and kerogen. Bitumen is then washed from the rock and DRIFTS is re-measured, resulting in an estimate of kerogen. Bitumen quantity is calculated by subtracting the washed sampled results from first DRIFTS measurements.
