Abstract: The present invention relates generally to systems and processes for improved drag reduction estimation and measurement and more specifically to portable drag reduction analyzers and processes for upscaling drag reduction data for a variety of field applications. A drag reduction parameter ΔB for the fluid mixture is used for determining drag reduction for a fluid mixture in an oil field or pipeline operation.

Abstract: The thickness of subsurface layers if they had remained as they were prior to compaction may be estimated by restoring the volume of void space lost during compaction. Decompacted depths below seafloor, the depths the layers would be if compaction had not occurred, may be determined for the layers. A surrogate decompaction velocity may then be determined by dividing the decompacted depths by the travel times of acoustic waves that reflect off layers within the subsurface region. The decompaction velocity may be used in post-processing of acoustic data to produce a decompacted digital representation of the subsurface region. The decompacted digital representation may be used to directly interpret the thickness of layers prior to compaction, sedimentation rates over time, fault offsets, and other phenomena distorted by compaction.

Abstract: A graphical user interface provides visualization of operation tasks for a well ordered in a sequence. The graphical user interface shows different types of timing for the operation tasks, such as planned timing, estimated timing, and actual timing for the operation tasks. Different types of timing are arranged in a hierarchy so that setting one type of timing for an operation task overrides another type of timing for the operation task. Changes to timing of an operation task are automatically propagated to other operation tasks.

Abstract: A method for identifying an unidentified subterranean sample may include comparing values for a subset of fluid chemistry parameters associated with the unidentified subterranean sample to values of corresponding fluid chemistry parameters associated with a plurality of identified subterranean samples. The method may also include determining, based on comparing the values for the subset of fluid chemistry parameters associated with the unidentified subterranean sample to the values of the corresponding fluid chemistry parameters associated with the plurality of identified subterranean samples, an estimated value for a target parameter associated with the unidentified subterranean sample. The method may further include recategorizing the unidentified subterranean sample as being among the plurality of identified subterranean samples based on the estimated value for the target parameter.

Abstract: A fuel composition is described. The composition contains gasoline and an aryloxy alkylamine additive. The structure of the aryloxy alkylamine additive is given by
where the aryloxy alkylamine additive is present in about 10 to about 750 ppm by weight based on total weight of the fuel composition. X is a hydrocarbyl group having 1 or 2 carbon atoms. R1 and R2 are independently hydrogen or substituted hydrocarbyl group having up to 36 carbon atoms.-

Abstract: A system for detecting cracks in an underwater structure can include an acoustic signal transmitter configured to be disposed proximate to, but without physically contacting, the underwater structure, where the acoustic signal transmitter is configured to emit acoustic signals. The system can also include an acoustic field receiver configured to be disposed proximate to, but without physically contacting, the underwater structure, where the acoustic field receiver is configured to receive resulting acoustic fields. The system can further include a controller that is configured to receive the resulting acoustic fields from the acoustic field receiver. The controller can also be configured to analyze the resulting acoustic fields signal. The controller can further be configured to detect, based on analyzing the resulting acoustic fields, a crack in the underwater structure.

Abstract: Provided is a composition comprising a blend of a waste plastic and a bio feedstock. Also provided is a process for preparing a stable blend of a plastic and bio feedstock which can be stored or transported if desired. The amount of plastic in the blend comprises no more than 20 wt. % of the blend. The blend can be passed to a conversion unit for conversion of the waste plastic and bio feedstock. The conversion process produces clean monomers for polymerization and chemical intermediates.
