... Abstract Sensitivity of the electromagnetic (EM) field to resistivity ahead of the bit has been proven for Ultra-Deep Azimuthal Resistivity (UDAR) tools, and is actively being used in near vertical wells along with 1D inversion. Inverting for resistivity ahead in horizontal wells would allow...

... calibration. The R factor, also known as the dilation factor, expresses the sensitivity of seismic velocity variations to vertical strain. The fundamental goal of this study is to understand the behaviour of R factors during deformation in an effort to improve predictive models for subsurface deformation...

... of experiment is created with individual pattern's injection rate and concentration as primary variables. The objective function is defined to maximize sweep efficiency, oil recovery and polymer flood efficiency for short term interval. More than 1000 experiments were created and run to identify sensitivity...

... demonstrates that the diagnostic model can be easily calibrated with a single separator test close to its critical flow conditions. Future research could include additional reservoir parameters sensitivities such as skin, permeability, relative permeability, hysteresis, fluid types and finally incorporate...

... density devices have almost no sensitivity to liquid phase in flowing passes; shut-in data provide very limited information of liquids which is too uncertain to be quantified. The most robust measurement for fluid phase determination consists of an array of local probes in the flow diagnostic tool; good...

... is particularly adapted to highly concentrated and viscous solutions since it is not sensitive to the presence of particles, gel debris and oil. Two high pressure viscometers can be connected at any point of the high pressure injection line (well head for example) to monitor continuously the viscosity...

... flow in porous media Fluid Dynamics sensitivity iteration application permeability adjoint run Introduction A successful implementation and interpretation of EOR technology in a field depends on the understanding of the reservoir and the design aspects of the technology itself. A good...

... understanding of the field characteristics and fluids movement, different actions were planned in order to maximize oil recovery. In particular, a screening of possible IOR/EOR techniques showed immiscible WAG as the most promising one to recover un-swept attic oil. Several sensitivities were performed on water...

The first part of this paper presents the basic modelling workflow for DEW for light to medium oils and typical concentration and saturation profiles and ternary...
