Abstract: The present disclosure relates to passive flow control devices or FCDs and modeling methods applicable to same. In particular, a new method to extrapolate the value of a reference FRR tool to other tools with the same architecture, but different ratings. Instead of scaling the output of the model, the data of the available characterizations is used to extrapolate what the characterization results would be to the different FRR. This estimated data set is then used to fit a new model for the uncharacterized FRR tool.

Abstract: The invention relates to the cleaning of a wellbore including a reservoir liner 3 and an upper portion 2 of the wellbore, by running in only one string into the wellbore and performing a reservoir liner cementing operation, displacing the cement 7 with completion fluid 8, followed using the same string to circulate mud in the upper completion, perform an inflow test on the reservoir liner 3, wash the upper completion and displace it to completion fluid 8.

Abstract: Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.

Abstract: Methods and systems are provided for quantifying contributions of gas mixtures in a reservoir compartment by way of isotopic analyses. Differing thermal maturities of the different gas mixtures allow estimation of the relative quantity of each gas mixture present in a total gas mixture. Thermal maturities may be estimated by reference to isotopic analyses of each contributing gas mixture and a commingled gas mixture resulting from commingling each of the individual source gas mixtures. This method may be carried out at various depths to determine relative contributions of each gas mixture to the total gas mixture as a function of wellbore depth. Advantages of certain embodiments include, but are not limited to, higher accuracies and ease of application as compared to conventional methods.

Abstract: A method for obtaining hydrocarbon from a reservoir in a subterranean formation is described. The method includes measuring a poromechanic pressure change due to lithostatic load sharing in the subterranean formation. Mapping the poromechanic pressure change to one or more locations in the subterranean formation. Identifying one or more local pressure peaks in the poromechanic pressure change, wherein the one or more local pressure peaks are each marked by a pressure escalation and subsequent pressure depletion. Determining one or more regions in the reservoir exhibiting single phase hydrocarbon production.

Abstract: Methods, systems and designs are provided for removing mercury from crudes. Crude oil containing a synthetic reducing agent is heated to a temperature above 100° C. and held at that temperature for a specified period of time to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by e.g., flashing the hot oil and/or contacting it with a gas phase.
