Abstract: A core-in-shell heat exchanger, a method of fabricating the core-in-shell heat exchanger, and a method of exchanging heat in a core-in-shell heat exchanger disposed on a slosh-inducing moving platform are described. The method of exchanging heat includes introducing a shell-side fluid into a shell of the core-in-shell heat exchanger and introducing a fluid to be cooled into each of one or more cores of the core-in-shell heat exchanger, the one or more cores being arranged along an axial length of the shell with a plurality of baffles disposed on either side of the one or more cores along the axial length of the shell to reduce slosh of the shell-side fluid. The method also includes draining excess shell-side fluid using a plurality of drains, at least two of the plurality of drains being disposed on opposite sides of one of the plurality of baffles.

Abstract: This disclosure describes a method of combining DAS and DTS data to accurately estimate borehole temperature. The described method takes advantage of the thermal sensitivity of DAS signal in the low-frequency band, and combines with the absolute temperature measurement from DTS, to produce a distributed temperature estimation that is up to 10000 more accurate than the current commercial solution. The DAS and DTS data should be record simultaneously at the same well. The DAS data are first low-pass filtered and then converted into temperature variation measurement. Then an accurate temperature estimation is obtained by fitting both DTS and DAS data.

Abstract: A method for making changes to a salt model are described. In particular, an algorithm allows a user to interactively edit a salt model to reflect migrated seismic data to improve model accuracy without having to select horizons that overlap or are sealed or decrease the resolution of the horizons. Instead, sealed horizon pairs are automatically generated from the edited data using a new algorithm.

Abstract: A method of blowdown for a steam chamber of a thermal recovery process is provided. A blowdown mixture is introduced into the steam chamber. The blowdown mixture can include glycol and water. Heat can be adsorbed from the steam chamber onto the blowdown mixture. A viscosifying agent can also be introduced into the steam chamber. Oil from the steam chamber can be emulsified with the viscosifying agent to produce oil or emulsions of oil. The blowdown mixture and the oil or emulstions of oil can both be recovered from the steam chamber.

Abstract: The invention relates to systems, processes and apparatuses for determining a rig-state of a drilling rig during a wellbore drilling operation and detecting and mitigating drilling dysfunctions. These systems, processes and apparatuses provide a computer with a memory and a processor, a plurality of sensors associated with a wellbore drilling operation for acquiring time series data wherein the data are formatted for sample and bandwidth regularization and time-corrected to provide substantially time-synchronized data, a processing graph of data-stream networked mathematical operators that applies continuous analytics to the data at least as rapidly as the data are acquired to determine dynamic conditions of a plurality of rig conditions associated with the wellbore drilling operation and determining a rig-state from the plurality of rig conditions.

Abstract: This disclosure describes a method of calculating fluid distribution from a hydraulically fractured well, especially during a plug-and-perf hydraulic fracturing operation. The Distributed Acoustic Sensing (DAS) data is used to quantify the fluid distribution in separate perf clusters during fracturing, and the result can be used for completion design and optimization, hydraulic fracturing, and ultimately for oil and gas production.

Abstract: The present disclosure relates to a particularly effective well configuration that can be used for steam-drive based oil recovery methods. Fishbone multilateral wells are combined with steam drive, effectively allowing drive processes to be used where previously the reservoir lacked sufficient injectivity to allow steam drive or cyclic steam based methods.

Abstract: A system and method for well abandonment, comprising installing a first steel plate comprising a hole having a pipe section attached above the hole, wherein a coupler may be installed to house a stopper which is then positioned below the surface casing having a second steel plate, the capping plate, affixed to the top of the surface casing. The stopper system then acts to prevent the exchange of wellbore fluid into the environment while allowing for proper venting of casing strings by pressure actuating the stopper system against the cap. The coupler further provides for attachment of various gas sampling or other monitoring equipment in for purposes of detection of leaks or other analytical objectives.

Abstract: A method for modeling and analyzing the impact of different seismic surveying and imaging techniques on a subterranean formation uses a black hole boundary condition around a particular region in the formation where at least one of the physical characteristics is unclear and may distort the seismic modeling results. The black hole boundary conditions will eliminate any energy wave that enters, exit or reflect off the region so as to avoid any image distortion caused by this region. The resulted image data is compared with the image data obtained without using the black hole boundary conditions to determine the impact of this region, and proper correction can be made to more precisely and accurately model the formation.
