Abstract: A graphical user interface may provide visualization of comparison between planned value(s) and usage value(s) of a set of operating parameters for a tool. The graphical user interface may include a planned usage region and a usage region. The planned usage region may provide visualization of the planned value(s) for the tool. The usage region may provide visualization of the usage value(s) for the tool. The usage region may include a compliance section. The compliance section may provide visualization of whether the usage value(s) complies with the corresponding planned value(s) such that the compliance section includes different visual features based on whether the usage value(s) complies or does not comply with the corresponding planned value(s). The usage region may provide comments and/or recommendations based on the learnings from analysis of offset wells.

Abstract: Provided herein are liquid polymer (LP) compositions comprising a synthetic (co)polymer (e.g., an acrylamide (co)polymer), as well as methods for preparing inverted polymer solutions by inverting these LP compositions in an aqueous fluid. The resulting inverted polymer solutions can have a concentration of a synthetic (co)polymer (e.g., an acrylamide (co)polymer) of from 50 to 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 μm filter. Also provided are methods of using these inverted polymer solutions in oil and gas operations, including enhanced oil recovery.

Abstract: Systems and methods are disclosed for generating subsurface feature prediction probability distributions from a subsurface feature as a function of position in a subsurface volume of interest. For example, a computer-implemented method may include: obtaining subsurface data and well data, generating subsurface feature values, generating subsurface feature realizations, generating subsurface feature realization uncertainty values, generating subsurface parameter values, generating subsurface parameter realizations, generating subsurface feature prediction probability distributions, generating a first representation of likelihoods of the subsurface feature values, and displaying the first representation.

Abstract: Disclosed are systems and methods for thermal management of subsea conduits. A jumper that carries oil and/or gas produced from a subsea well in a subsea production facility located on a seabed has a first end for connecting to a first subsea component and a second end for connecting to a second subsea component. The jumper includes a jumper segment that is sloped relative to the horizontal, such that gravity assists with drainage of fluid from the second end of the jumper independent from fluid pressure in the jumper. At least a portion of the jumper is uninsulated to allow exchange of heat with seawater surrounding the jumper as produced fluid travels through the jumper. The amount of insulation on the jumper can be varied such that heat transfer from the production fluids to seawater surrounding the jumper circuit is adjusted as desired.

Abstract: A subterranean coring assembly can include a body having at least one wall that forms a cavity, wherein the cavity has a top end and a bottom end. The subterranean coring assembly can also include a first flow regulating device movably disposed within the cavity, where the first flow regulating device is configured to move from a first default position to a first position within the cavity based on first flow characteristics of fluid that flows into the top end of the cavity toward the bottom end of the cavity.

Abstract: Embodiments of estimating unknown proportions of a plurality of end-members in an unknown mixture are provided herein. One embodiment of a method of estimating unknown proportions of a plurality of end-members in an unknown mixture comprises receiving fingerprint data of a plurality of end-members and an unknown mixture comprising unknown proportions of the plurality of end-members; processing the fingerprint data of the plurality of end-members and the unknown mixture to generate peak height data of the plurality of end-members and the unknown mixture; and generating an estimate of the unknown proportions of the plurality of end-members in the unknown mixture by applying a Markov Chain Monte Carlo method to the peak height data of the plurality of end-members and the unknown mixture.

Abstract: A system for developing multiple subterranean wellbores in a land-based field can include a first operational platform disposed over a first entry point of a first subterranean wellbore at a first time. The system can also include a second operational platform disposed over a second entry point of a second subterranean wellbore at the first time, where the first entry point and the second entry point are located proximate to each other. The system can further include first field equipment disposed on the first operational platform. The system can also include a second field equipment disposed on the second operational platform. The first field equipment can be used to develop the first subterranean wellbore, and the second field equipment can be used to develop the second subterranean wellbore.

Abstract: A continuous process for converting waste plastic into recycle for polypropylene polymerization is provided. The process integrates refinery operations to provide an effective and efficient recycle process. The process comprises selecting waste plastics containing polyethylene and polypropylene and then passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a refinery FCC unit, from which is recovered a liquid petroleum gas C3 olefin/paraffin mixture. The C3 paraffins and C3 olefins are separated into different fractions with a propane/propylene splitter. The C3 olefin fraction is passed to a propylene polymerization reactor. The C3 paraffin fraction is optionally passed to a dehydrogenation unit to produce additional propylene and then the resulting C3 olefin is passed to a propylene polymerization reactor. The heavy fraction of pyrolyzed oil is passed to an isomerization dewaxing unit to produce a lubricating base oil.
