摘要： Conventional optical analysis tools containing an integrated computational element may have an operational profile that is too large for convenient use within confined locales. Optical analysis tools having a miniaturized operational profile can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical train; and an optical computing device positioned within the optical train. The optical computing device comprises a planar array detector having at least two optical detection regions. At least one of the at least two optical detection regions has an integrated computational element disposed thereon. The planar array detector and the integrated computational element are in a fixed configuration with respect to one another.

摘要： Certain aspects and features of the disclosure relate to an anchor for a linear actuator. In one example, the anchor includes a body, a mandrel with at least two slip-receiving portions, and one or more slips. The body can be coupled to the linear actuator and the mandrel can be coupled to the power rod of the linear actuator. The linear actuator can power on and cause the power rod to move in an uphole direction toward the linear actuator. Moving the power rod can cause the mandrel to move in an uphole direction. The slip can respond to the mandrel moving in an uphole direction by expanding outward. The mandrel can continue to move in the uphole direction until the slip is received at a second slip-receiving portion.

摘要： A wellbore isolation tool, e.g., a bridge plug, provides the ability to seal portions of a well from production or to temporarily seal zones of a well from treatment. A bridge plug may include a sealing element supported by one or more segmented barrier devices that operate to prohibit extrusion of the sealing element as the sealing element is subjected to an axial force. The segmented barrier device may operate passively as segments are driven radially outward by the radial expansion of the sealing element when subject to the axial force and driven radially inward by leaf springs when the axial force is removed. Segments of the segmented barrier device may circumferentially overlap and form a generally flat shoulder supporting the sealing element. The segmented barrier device may include a jacket covering the segments, and a sealing element may be supported by a segmented barrier device on each axial end.

摘要： A wellbore sealing device having an elastomeric element with complex features and associated additive manufacturing method is disclosed. The complex features can include voids such as isolated voids and undercut-like voids that cannot be reasonably produced using existing molding techniques (e.g., due physically impossible mold shapes or cost-prohibitive mold requirements). These complex features can alleviate stress and increase radial expansion of the elastomeric element in response to axial compression of the elastomeric element. Such elastomeric elements with complex features can be additively manufactured (e.g., through three dimensional printing). In some cases, the elastomeric elements can be additively manufactured directly on a tool, such as on an end plate or mandrel of a wellbore sealing device.
