| Values for porosity and permeability of core samples in a borehole are estimated by generating radial waves with an acoustic source in fluid around the core sample, and measuring pressure in the fluid. Moreover, the acoustic source operates at frequency close to a resonant frequency of the core sample. After the acoustic source no longer operates at the resonant frequency, pressure in the fluid attenuates over time. The pressure attenuation is recorded by the pressure measurements, along with the pressure in the fluid at the first harmonic (spectral component). The pressure attenuation and spectral component each are dependent on porosity and permeability of the core sample. Thus values for the porosity and permeability are determined based on the arithmetic relationships between pressure attenuation and the spectral component and porosity and permeability. | ||||||

The core sample is a 3D porous medium representing a portion of the oilfield. The 3D pore scale model describes a physical pore structure in the 3D porous medium. Simulations are performed using the EOR scenarios to obtain simulation results by, for each EOR scenario, simulating, on the first 3D pore scale model, the EOR injection operation using the chemical agent specified by the EOR scenario to generate a simulation result. A comparative analysis of the simulation results is performed to obtain a selected chemical agent. Further, an operation is performed using the selected chemical agent. | ||||||

| 337 | Improvements relating to core barrel outer tubes | US13795507 | 2013-03-12 | US09238946B2 | 2016-01-19 | Olivier Jean-Marc Claude Mageren |
| Described herein is a “cross-over” connector that can be used with core barrel outer tubes to prevent damage and destruction when they are connected to one another by automated equipment on a rig floor, for example, automated rig-floor torque wrenches. Standard core barrel outer tubes having a pin connector and a box connector are modified by adding “cross-over” sub elements to the pin and box connectors to increase their effective strength. The sub elements include portions which engage respective ones of the pin and box connections. The sub elements are designed to be the contact points for the automated equipment, so that it they are damaged, they can readily be replaced at a lower cost when compared to the scrapping and replacement of the core barrel outer tubes themselves. | ||||||
