Abstract: A method for selecting core points in subsurface formations includes selecting a zone from at least one subsurface formation. At least one statistical measure of at least one petrophysical measurement with respect to position along the selected zone is calculated. A predetermined number of core points at randomly selected positions along the selected zone is selected The at least one statistical measure is calculated for the randomly selected positions. Using a Monte Carlo iteration, the positions along the selected zone are randomly reselected and the at least one statistical measure is recalculated for the randomly reselected points until the at least one statistical measure for the randomly selected points is a maximum for a user selected statistical criterion applied to the at least one statistical measure of at least one petrophysical measurement with respect to position along the selected zone.

Abstract: A method includes completing multiple wellbores in a subsurface formation. The method includes a first wellbore having been drilled along a first selected trajectory through the subsurface formation. The first wellbore is fracture treated. A second wellbore is drilled along a second selected trajectory through the subsurface formation. The second trajectory is laterally spaced from the first trajectory. The second wellbore is fracture treated. A third wellbore is drilled along a third selected trajectory through the subsurface formation. The third trajectory is disposed between the first and second trajectories. The third wellbore is fractured treated such that a fracture network extending therefrom hydraulically connects to fracture networks extending from the first and second wellbores and hydraulically connects the first, second and third wellbores proximate an upper end thereof so that the first, second and third wellbores may all produce fluids.

Abstract: A method for seismic surveying includes deploying a group of vertically sensitive seismic particle motion responsive sensors at each of a plurality of geodetic survey positions. The groups each include at least two sensors spaced apart by a first selected horizontal distance. The groups are separated from each other by a second selected distance larger than the first distance. Signals detected by each of the sensors resulting from actuation of a seismic energy source are recorded. At least one of an in-line and a cross-line component of a gradient of the vertical component of the seismic wavefield is determined at each group location by determining a difference between the signals detected by each sensor in a respective group.

Abstract: A system for cementing a wellbore penetrating an earth formation into which a pipe extends. A cement material is positioned in the space between the wellbore and the pipe by circulated capsules containing the cement material through the pipe into the space between the wellbore and the pipe. The capsules contain the cementing material encapsulated in a shell. The capsules are added to a fluid and the fluid with capsules is circulated through the pipe into the space between the wellbore and the pipe. The shell is breached once the capsules contain the cementing material are in position in the space between the wellbore and the pipe.

Abstract: Methods and systems of enhanced carbon dioxide recovery from an inlet gas stream are provided, by introducing the gas stream to one or more membrane-based separation units to produce a permeate byproduct gas stream having increased concentration of carbon dioxide compared to the inlet gas stream and then introducing the permeate byproduct gas stream to one or more pressure swing adsorption units or trains to enhance recovery of hydrocarbons, such as methane, lost in the byproduct stream and to produce a substantially pure carbon dioxide stream, while minimizing process compression and eliminating process heat for process regeneration. The methods introduced herein are for enhancing product recovery by enhancing carbon dioxide recovery from gas streams with pressures greater than atmospheric conditions. Further refinement to the methods would be the introduction of hydrogen sulfide polishing units within the process to produce product that meets or exceeds sales quality specifications.
