Abstract: A latching apparatus includes a body, a fin biased to protrude from the body, and a biasing element for so biasing the fin. A method for securing a tool in a drilling tubular includes connecting the tool to a latching apparatus, the latching apparatus including a fin biased to protrude radially outward, forcing the latching apparatus into the drilling tubular, and forcing the latching apparatus through a landing ring.

Abstract: A shock absorber apparatus includes a rod; a tool connection on a first end of the rod; a piston on a second end of the rod; a flange on the rod between the tool connection and the piston; a ring connection slidably connected to the rod between the tool connection and the flange; a first spring between the ring connection and the flange to bias the ring connection axially away from the flange; a sleeve, connected to a second spring between the second spring and the piston, slidably encircling the piston and a portion of the rod, and extending past the piston to a pumpdown connection; and a fin. A method for a placing a tool in a landing ring of a drilling tubular includes using the shock absorber apparatus to absorb shocks caused by the landing operation.

Abstract: A server-based Internet service, with client-side applications, is described that enables users to communicate between electronic devices such as smartphones, tablets and personal computers by broadcasting live video, voice and/or text via an internet protocol (IP) address. Broadcasting can be done in both private and public formats. Private broadcasts can be made ‘one-on-one’ between two registered users or among a group of private contacts. Public broadcasts can be accessed by any registered users and can also be transmitted to registered ‘Followers’. In addition to designating ‘Followers,’ users can also designate types of content that they wish to follow, e.g. video, voice and/or text. Broadcasts are stored on service provider servers where they can be searched by title, category, proximity or by description, and accessed at a later time. Broadcasts may also be designated as ‘Favorites’ for easier access in the future. Once accessed, broadcasts can be organized alphabetically or chronologically.
