Abstract: A method for estimating values of well log measurements of a first selected type in wellbore sections wherein the measurements of the selected type are determined not to be valid includes establishing a linear relationship between measurements of a first selected type and measurements of a second selected type. The measurements of the second selected type are substantially valid over an entire measured axial section of the wellbore. Correct values of the measurements of the first type in the wellbore sections using measured values of the second type and the linear relationship.

Abstract: 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. The transmitting and recording of signals is repeated for a plurality of different spacings between the energy sources. 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 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: A method for removing acid-gases from water includes introducing acid into a flow of aqueous solution having acid-gases and associated conjugate bases having an initial pH to lower the pH. The lowered pH solution has a stripping gas passed therethrough, resulting in a vapor phase of liberated acid-gas and stripping gas vapors, and a liquid phase comprising a lower concentration of acid-gases and associated conjugate bases than the aqueous solution. The liberated acid-gas and stripping gas vapors are collected and treated to remove acid-gas components, resulting in clean stripping gas product. The liquid phase is separated and collected with a second treating step, resulting in a final aqueous product having a lower concentration of acid-gases and associated conjugate bases than the liquid phase.
