    Abstract: The invention relates to a method, system and apparatus for synchronizing the time of time series data acquired from a wellbore sensor relative to a reference time series. This comprises acquiring a first time series from a sensor in a wellbore, acquiring a reference time series and determining a linear moveout time correction to apply to the first time series. The linear moveout time correction is equal to the depth of the wellbore sensor divided by the signal propagation velocity. The linear moveout correction is applied to the first time series. The first time series is cross-correlated with the reference time series to determine a cross-correlation time correction to apply to the first time series and the cross-correlation time correction is applied to the first time series to obtain a cross-correlation corrected time series. Dynamic time warping and dynamic cross-correlation may be used to adjust for clock drift.

    Abstract: Vibrators for producing seismic signals for use in oil and gas exploration are equipped with segmented base plates, each segment being independently controlled and activated. The use of an array of base plate segments allows the individual segments of the array to be activated in a particular pattern, thus generating S-waves and other unconventional wave patterns for seismic use.

    Abstract: A seismic measurement system and a method of obtaining seismic measurements are described. The seismic measurement system includes a cable and a plurality of sensors disposed at a first interval along the cable. The plurality of sensors receives reflections resulting from a seismic source and each of the plurality of sensors receives the reflection corresponding with a particular subsurface location. The system also includes a controller to turn on a first set of the plurality of sensors and turn off a second set of the plurality of sensors based on an area of interest.

    Abstract: Methods and systems relate to recovering hydrocarbons from within formations in which hydrocarbon bearing reservoirs are separated from one another by a fluid flow obstructing natural stratum. Relative to the reservoirs, the stratum inhibits or blocks vertical fluid flow within the formation. Lateral bores divert from lengths of injector and producer wells along where extending in a horizontal direction. These bores pass upward through the formation to intersect the stratum and provide an array of fluid flow paths through the stratum. In a side direction perpendicular to the horizontal direction of the wells, the lateral bores from the injector well pass through the stratum inside of where the lateral bores from the producer well pass through stratum. Fluid communication established by the bores limits counter-current flow through the bores in processes that rely on techniques such as gravity drainage.
