    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 wave glider system includes a float having geodetic navigation equipment for determining a geodetic position and heading thereof. The glider includes an umbilical cable connecting the float to a sub. The sub has wings operable to provide forward movement to the float when lifted and lowered by wave action on the surface of a body of water. At least one geophysical sensor streamer is coupled to the sub. The at least one geophysical sensor streamer has a directional sensor proximate a connection between the sub and one end of the at least one geophysical sensor streamer to measure an orientation of the streamer with respect to a heading of the float.

    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.
