Apparatuses for interaction with a subterranean formation, and methods of use thereof
First Claim
1. An access casing assembly for providing access to a subterranean formation, comprising:
- a casing portion comprising a plurality of casing sections operably coupled to form a central elongated cavity;
a tip portion affixed to an end of the casing portion and including a porous filter through which liquid or gas may communicate with the central elongated cavity;
a receiving member positioned proximate the tip portion forming a portion of the central elongated cavity, wherein the receiving member includes an engagement feature configured for selectively and lockingly engaging a locking structure of a device to be positioned at a sampling position within the access casing assembly;
wherein the access casing assembly is structured for placement at least partially within a subterranean formation by forcing the access casing assembly thereinto; and
wherein the access casing assembly is configured for receiving the device in the sampling position within the access casing assembly after the access casing assembly is placed at least partially within the subterranean formation.

Abstract
An access casing assembly structured for placement at least partially within a subterranean formation by forcing the access casing assembly thereinto, comprising a plurality of casing sections operably coupled to form a central elongated cavity for providing access to the subterranean region is disclosed. Further, a tip portion of the access casing assembly may include a porous filter through which liquid or gas may communicate with the central elongated cavity. Also, a receiving member or at least one engagement hub may form a portion of the central elongated cavity and may include an engagement feature configured for selectively and lockingly engaging a locking structure of a device to be positioned within the access casing assembly. Methods of use are disclosed. A tensiometer is disclosed including a chamber structured for allowing at least partially filling with a fluid subsequent to contact therewith.
