Abstract: Method and system are described for modeling one or more geophysical properties of a subsurface volume. The method includes computing vector volumes to enhance subsurface modeling and update these vector volumes. The vectors are estimated (106) from the data, for example dip or azimuth, and then the vector volume may be updated by an optimization process (808). Flattening the original data (802) may assist the vector estimation, and associating data traces and samples of traces with labels (108) may assist the flattening. The vector volume may then be used to extract horizons (110) and generate a stratigraphic model (112) to enhance the process of producing hydrocarbons (114).

Abstract: A valid configuration of a product is determined by a computer based on a complete product model. The initial product model includes variables with associated values, and rules, wherein the variables and rules define a configuration problem to be solved. Some variables of the initial product model are defined as scope variables. Based on the selected values for scope variables the initial product model is restricted by the computer to a simplified product model. The simplified product model is employed in order to set the values of the variables not being defined as scope variables in an iterative computer-implemented process.

Abstract: The invention is a method for determining an amount of hydrogen sulfide produced by aquathermolysis induced by a thermal process, such as steam injection. The hydrocarbons are described with a compositional representation using H2S and the fractions saturated compounds, aromatics, resins and asphaltenes. A kinetic model is constructed based on the compositional representation using an elementary model obtained by mass balance for sulfur distributed within the fractions. A thermodynamic model is constructed based on the same compositional representation. The amount of produced H2S is determined by performing a compositional reservoir simulation using a compositional and reactive thermal simulator using the kinetic and thermodynamic models.

Abstract: Diagnosing a pump apparatus having a downhole pump disposed in a deviated wellbore characterizes axial and transverse displacement of a rod string with two coupled non-linear differential equations of fourth order, which include axial and transverse equations of motion. To solve the equations, derivatives are replaced with finite difference analogs. Initial axial displacement of the rod string is calculated by assuming there is no transverse displacement and solving the axial equation. Initial axial force is calculated using the initial axial displacement and assuming there is no transverse displacement. Initial transverse displacement is calculated using the initial axial force and the initial axial displacement. Axial force and friction force are calculated using the initial displacements, and the axial displacement at the downhole pump is calculated by solving the axial equation with the axial force and the friction force. Load at the downhole pump is calculated so a downhole card can be generated.
