Fluid Imaging

Geoscientists and reservoir engineers are challenged to integrate data of different scales to better understand fluid movement in oil reservoirs. Different technologies are capable of imaging fluid movement in the reservoir at different scales. Two-dimensional fluid imaging has been achieved recently through crosswell and surface-to-borehole electromagnetic (EM) measurements. Three-dimensional fluid movement imaging has shown potential by using surface seismic data volumes. The Multiscale Reservoir Surveillance and Monitoring Workshop, held virtually 7–9 December 2020, attempted to address the challenge of how to integrate these measurements obtained at different scales into a workflow to improve the understanding of fluid flow, which is critical for sweep efficiency and recovery.

There are many limitations in the ultimate accuracy of a conventional two dimensional seismic survey. One of the most important of these is that, in general, a prospect is not a two dimensional model but a three dimensional one. For a complete interpretation of a prospect area the final result should be a migrated time or depth map. With limited sampling (a seismic grid typically consists of loops with dimensions at least 1 km by 1 km) it is necessary to interpolate grid points to allow map migration and this method has inherent inaccuracies.The three dimensional seismic exploration technique is designed to provide a sufficiently close sampled grid of seismic traces, typically with a line and depth point spacing as close as 50-100 m, to allow the seismic data itself to be migrated three dimensionally. This allows the interpreter to work with migrated seismic sections and to contour directly the migrated map.Several techniques exist to allow practical and economic collection of seismic data to provide this close sampling. These techniques can be adapted to various terrain and cultural conditions.The main advantages of three dimensional data collection are correct imaging of the seismic information giving true vertical reflection time sections and improved signal-to-noise ratio due to the increased fold inherent in the three dimensional migration process. The additional advantage to the interpreter is that the data has a sampling which gives a line intersection at each depth point in the prospect.

Turbulent Incompressible Fluid

We propose a model for random forces in a turbulent incompressible fluid by balancing the energy gain from fluctuations against dissipation by viscosity. This leads to a more singular covariance distribution for the random forces than is ordinarily allowed. We then propose regularization of the fluid system by matrix models. A formula for entropy of a two dimensional fluid is derived and then a vorticity profile of a hurricane that maximizes entropy. A regularization of three dimensional incompressible fluid flow using quantum groups is also proposed.

Good Agreement

Fully three dimensional fluid flow simulations are used with a simple structural model to simulate very long risers. This method overcomes many shortcomings of methodologies based on two dimensional flow simulations and can correctly include the effects of three dimensional structures such as strakes, buoyancy modules and catenary riser shapes. The method is benchmarked against laboratory and offshore experiments with model risers of length to diameter ratios up to 4,000. RMS values of vortex induced vibration motions are shown to be in good agreement with measurements. The resources needed to model ultra deep water drilling and production risers are estimated based on current computer technology.

This paper reports an efficient electro-thermal modeling technique for the Micro Flow Sensor (MFS) having an ensured thermal insulation structure with a thin silicon nitride membrane. Both the thermal fluid flow around two-heater MFS and the electric circuit were modeled together using a commercial general-purpose circuit simulator based on SPICE (Simulation Program with Integrated Circuit Emphasis). Two-dimensional laminar Poiseuille channel flow was assumed as the flow field in the model. Remarkable features of this technique are as follows: a partial three-dimensional lumped thermal network model involved in a two dimensional one, single segment for spanwise direction, and the forced convective heat transfer calculated by energy balance at each node in the fluid flow. The simulation and measurement results on the sensor characteristics were in good agreement.

The phenomenon of three-dimensional (3D) steady-state motion of a string traveling along an invariant curve in a flowing medium is studied. Existence conditions are found using a perturbation scheme where a known two-dimensional (2D) solution is used as an initial approximation.
