    Abstract: The present disclosure relates to making seismic measurements using a seismic source disposed in a wellbore. One or more seismic sources are provided and carried on a conveyance mechanism. One or more seismic receivers are provided and placed on or near the earth's surface, the same wellbore as the seismic sources, or in another wellbore. The one or more seismic sources are run into and/or out of the wellbore using controller or sequencer. The one or more seismic sources are positioned, manually or automatically, at one or more locations in the wellbore, using a set of computer-controlled instructions. Seismic measurements are made at one or more locations by activating one or more seismic sources and detecting a seismic source signal using seismic receivers. The receivers may be carried on a conveyance mechanism and their position controlled, manually or automatically, using the set of computer-controlled instructions.

    Abstract: A treatment process for an aqueous phase which contains oil droplets, which may be droplets of 10-50nm diameter in aqueous flow from a hydrocyclone separator, comprises bringing the water into contact with a surface subdivided into areas of differing surface energy and affinity for oil and such that when the surface is submerged in an aqueous phase, oil droplets adhere to it with an apparent contact angle in a range from 90 to 150 degrees. In some embodiments, areas of the surface reduce their affinity for oil in response to an external stimulus, and the process comprises applying the external stimulus to cause controlled release of droplets adhering to the surface. The process may be used to remove oil droplets from water produced by an oil or gas well, after downhole oil water separation or after production at a at a well head, or used to coalesce droplets in such water to a larger size to enable conventional separation.

    Abstract: A shifting tool for use in shifting axial position of a shiftable element in a well. The tool comprises a linkage mechanism configured to translate an independent axial force into a dedicated radial force applied to expansive elements thereof. Thus, the elements may radially expand into engagement with the shiftable element free of any substantial axial force imparted thereon. As such, a more discretely controllable shifting actuation may be attained, for example, as directed from an oilfield surface. Indeed, real-time intelligent feedback may also be made available through use of such elements in conjunction with the noted linkage mechanism.

    Abstract: A technique facilitates actuation of a downhole tool, such as a valve, in a simple, rapid, and cost-effective manner. The technique comprises installing the downhole tool with a trip saver. The trip saver can be actuated by increasing a tubing pressure or other suitable pressure source beyond a threshold level. Once the trip saver is actuated, a fluid under suitable pressure is provided to a downhole tool through a passageway opened via the trip saver. This enables actuation of the downhole tool to a desired state.
