Abstract: A method and/or a system determines mechanical properties of a fluid-bearing formation. One or more packers may be used to measure and/or collect data regarding mechanical properties of a formation. The formation characteristics may be, for example, the stability of the formation, design parameters for frac-pack/gravel-pack operations, and sand production. The packer may expand within a wellbore of a formation until enough pressure is applied to fracture a wall of the wellbore. Before, during and/or after the fracturing of the wall, multiple measurements may be taken by the packer. After fractures are initiated, fluid may be pumped into and/or drawn from the formation using drains disposed on the packer. Additional packers may be used above and/or below the packer for isolating intervals of the wellbore.

Abstract: A remediation process that a employs improved quantitative method(s) of estimating of the volume and/or mass of contaminant in the subsurface, removal and or in situ degradation of the contamination using subsurface pulsing treatment (“SPT”) technology, and evaluation of the degree of remediation by re-applying the quantitative contaminant evaluation methods.

The process can quantitatively measure the amount of residual contaminant, which up until now has not been possible or tractable using in situ methods, as well as measure the amount of residual that can be removed by SPT.
