| 20090250208 | Tool And Method For Evaluating Fluid Dynamic Properties Of A Cement Annulus Surrounding A Casing - The permeability of the cement annulus surrounding a casing is measured by locating a tool inside the casing, placing a probe of the tool in contact with the cement annulus, measuring the change of pressure in the probe over time, where the change in pressure over time is a function of among other things, the initial probe pressure, the formation pressure, and the permeability, and using the measured change over time to determine an estimated permeability. The estimated permeability is useful in determining whether carbon dioxide can be effectively sequestered in the formation below or at the depth of measurement without significant leakage through the cement annulus. | 10-08-2009 |
| 20090250209 | METHOD AND TOOL FOR EVALUATING FLUID DYNAMIC PROPERTIES OF A CEMENT ANNULUS SURROUNDING A CASING - The permeability of the cement annulus surrounding a casing is measured by locating a tool inside the casing, placing a probe of the tool in hydraulic contact with the cement annulus, measuring the change of pressure in the probe over time, where the change in pressure over time is a function of among other things, the initial probe pressure, the formation pressure, and the permeability, and using the measured change over time to determine an estimated permeability. By drilling into the cement and making additional measurements of the change of pressure in the probe over time, a radial profile of the cement permeability can be generated. | 10-08-2009 |

| 20090272530 | ANNULAR REGION EVALUATION IN SEQUESTRATION WELLS - Methods and related systems are described for making measurements at multiple locations in an annular region of a cased sequestration well. A first tool module is positionable within the well and adapted to directly or indirectly measure changing pressure at a first location in the annular region of the well. A pressure change is induced at the first location in the annular region. A second tool module is positionable within the well and adapted to directly or indirectly measure changing pressure at a second location in the annular region. The measured pressure changes at the second location are in response to the induced pressure change at the first location. | 11-05-2009 |

| 20110099794 | DEVICE AND METHOD FOR PRE-TENSIONING A COUPLING - A coupling device provides a pre-tensioned coupling between a first member and a second member. The members are arranged to define a sealed compartment. A piston is housed within the compartment and is translated between the first member and the second member. A first ratchet lock is mounted within the second member and on translation of the piston, the first ratchet lock engages with the piston. A second ratchet is mounted within the second member and, on translation of the piston into the second member, the piston engages with the ratchet. The second ratchet is mounted on a piston, and translation of the second ratchet on the piston applies a tensile force to the first piston to tension or pre-tension the piston. As the ratchets substantially prevent reverse movement of the piston, the tensile force is retained. | 05-05-2011 |
