Abstract: A retrieving tool for retrieving an annular hollow baffle member in a wellbore. The baffle member has an interior bore and radially outwardly-biased collet finger protuberances on an exterior thereof matingly engaging a correspondingly-dimensioned annular recess within a landing sub of a well casing of the wellbore. The retrieving tool has a tubular body and a plurality of radially-outwardly-extendable dogs thereon. The tubular body and the dogs are sized that, when the dogs are retracted, the retrieving tool is movable through the interior bore of the baffle member to a position below a lowermost thereof, and when the dogs are extended after the retrieving tool moves to said position, the dogs radially engageable with the landing sub and axially engageable with the lowermost of baffle member for pulling the baffle member uphole and disengaging it from the landing sub for retrieving the entirety of the baffle member.

Abstract: A system and method for successively fracking a wellbore at spaced intervals along tubing having therein frac ports each openably closed by a sliding sleeve. The system has at least one actuation member and at least one cylindrical sand screen sub insertable into the tubing. Each actuation member has a collet sleeve with a radially-outwardly biased protuberance of a first profile configured to matingly engage an interior groove profile on at least one of the sliding sleeves and slide the sliding sleeve downhole to open the corresponding port. Each cylindrical sand screen sub has a dissolvable plug member or burst plate disposed on one end thereof allowing for the sand screen to be forced into the well by pressure acting against the plug or plate, and has a resiliently-outwardly biased protuberance configured for engaging a mating profile on the tubing and retaining the sand screen sub in a desired position.

Abstract: A sliding valve has a valve body, a sliding sleeve received in a longitudinal bore of the valve body, and a collet receivable in a longitudinal bore of the sliding sleeve. The valve body has one or more fluid ports on an uphole portion of the sidewall thereof. The sliding sleeve is movable between an uphole closed position closing the one or more fluid ports and a downhole open position opening the one or more fluid ports. The sliding sleeve has a sleeve-profile formed at least by one or more sleeve-grooves and one or more sleeve-ridges longitudinally distributed on an inner surface thereof. The collet has a flexible collet-profile formed by at least one or more collet-grooves and one or more collet-ridges respectively corresponding to the sleeve-grooves and sleeve-ridges. The length of each sleeve-ridge or collet-ridge is smaller than that of corresponding sleeve-groove or collet-groove.

Abstract: Methods and systems are disclosed that automatically determine solar access values. In one implementation, a 3D geo-referenced model of a structure is retrieved in which geographic location on the earth of points in the 3D geo-referenced model are stored or associated with points in the 3D geo-referenced model. Object point cloud data indicative of object(s) that cast shade on the structure is retrieved. The object point cloud data may be generated from one or more georeferenced images and the object point cloud data is indicative of an actual size, shape, and location of the object(s) on the earth. The structure in the 3D geo-referenced model is divided into one or more sections, which are divided into one or more areas, each area having at least three vertices. Then, a solar access value for the particular vertex is determined.

Abstract: A baffle system for use in well casing having a plurality of landed subs therein, for progressive injection of a fracking or treating fluid into a hydrocarbon formation via existing or created perforations in the well casing. The baffle members provide a plug seat, and are each frangibly affixed to a conveying tool and have collet finger protuberances thereon. The collet finger protuberances of each baffle are of a different width, and respectively engage only one annular recess of a corresponding width in a respective landing sub. Each annular recess and/or collet finger protuberance on an uphole edge thereof has a chamfer which allows disengagement of the collet finger protuberances and thus removal of the baffle member from the well casing upon upward force being applied to the baffle member. A method of using the baffle system is also disclosed.
