Abstract: A well advisor system and console for monitoring and managing well drilling and production operations. The system may be accessed through one or more workstations, or other computing devices, which may be located at a well site or remotely. The system is in communication with and receives input from various sensors. It collects real-time sensor data sampled during operations at the well site. The system processes the data, and provides nearly instantaneous numerical and visual feedback through a variety of graphical user interfaces ("GUIs"), which are presented in the form of an operation- specific console. The input and data provides information related to geologic uncertainty concerning a well being drilled, with a focus on the safety of the drilling operation.

Abstract: Apparatus and techniques are described, such as for obtaining information indicative of an acoustic characteristic of a formation, including using a transducer assembly, comprising a base plate, a first piezoelectric slab and a second piezoelectric slab. The base plate includes a first region extending axially in a first direction beyond the first and second piezoelectric slabs along a specified axis of the base plate and a second region extending axially in a second direction, opposite the first direction, beyond the first and second piezoelectric slabs. In various examples, a length of the first region along the specified axis is different than a length of the second region to provide an asymmetric configuration. In various examples, an anchoring element is mechanically coupled to the base plate at a location corresponding to a node location of a specified acoustic vibration mode.
