Abstract

A method for optimizing a well production forecast includes inputting into a computer: initial production rate measurements and probability distributions to estimate production forecast model parameters. The computer generates an initial forecast of fluid production rates and total produced fluid volumes using a selected production forecast model. After a selected time, the initial forecast is compared with actual production rate and total produced fluid volume measurements to generate an error measurement. Parameters of the selected production forecast model are adjusted to minimize the error measurement, thereby generating an adjusted production forecast model. The parameter adjustment and error measurement are repeated for a plurality of iterations to generate a plurality of production forecast models each having a determined likelihood of an error measurement. The plurality of production forecast models are displayed with respect to likelihood of error.

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.

A method for detemining an optimum spacing of seismic energy sources based on mutual admittance includes deploying a plurality of seismic energy sources along a source line, separated by a selected spacing. Seismic receivers are deployed along a receiver line orthogonal to the source line. Seismic energy is simultaneously transmitted from each of the plurality of seismic energy sources while recording signals from the seismic receivers.

Seismic energy in the recorded signals is determined in separate time windows selected to represent reflected body wave signal, and source generated ground roll noise, respectively. A signal-to-noise ratio with respect to the spacing of the seismic energy sources is calculated and the optimum spacing between energy sources is selected based on the signal-to-noise ratio.

Abstract

A method for formation structural interpretation while drilling a wellbore through subsurface rock formations includes interpreting rock formation strata with respect to measurements of a formation physical property made with respect to depth in an offset wellbore. A color is assigned to each of a plurality of selected value ranges of the measurements. The physical property of the formation is measured while drilling the wellbore through the subsurface rock formations. A color is assigned to the measurements made while drilling based on the assigned color to each of the selected value ranges. The assigned colors made while drilling are used to estimate a stratigraphic position of the wellbore during the drilling by comparing the assigned colors made while drilling to the colors assigned from the offset wellbore.

Abstract

A system for distributing fluid to a plurality of wellbores drilled from a common pad includes at least two fluid conduits extending between the wellbores. The fluid conduits are configured to couple at one end to a fluid pump. At least one remotely operable valve is hydraulically connected to each fluid conduit proximate each wellbore. At least one flow line hydraulically connects each remotely operable valve to each wellbore such that fluid moved through the flow line enters the wellbore. A control unit is disposed proximate the pad and is configured to operate the remotely operable valves.

Abstract

A method for marine seismic surveying includes towing a seismic sensors in a plurality of streamers in the water, actuating a seismic energy source in the water at selected times and detecting seismic signals at the sensors resulting from the actuation of the source. A data trace is created for each of the detected signals. At least one Fresnel zone is determined for at least some of the seismic data traces. A contribution of each of the traces to each one of a plurality of bins defined in a predetermined pattern is computed, based on the Fresnel zone associated with each trace. Based on the computed contributions, a maximum lateral distance between corresponding seismic sensors is determined that will result in a contribution sum above a selected threshold.
