Abstract: An imager and method for imaging fluid of a subsurface formation is disclosed. The imager includes a housing having a sidewall defining a passage to receive a core sample of the subsurface formation therethrough. The housing is positioned in a downhole tool and has a fluid inlet to receive fluid from the subsurface formation into the passage. The imager also includes a permanent magnet positioned in the sidewall of the housing, a radio frequency coil positioned in the sidewall of the housing between the permanent magnet and the passage, a gradient field in the sidewall of the housing between the permanent magnet and the radio frequency coil, and a chemically-selective imager. The chemically-selective imager is operatively connected to the radio frequency coil to selectively pulse frequencies according to a pulse sequence whereby individual fluid measurements of the sample are generated.

Abstract: A retrievable self-energizing top anchor tool with a central energizing mandrel disposed around a central tool bore and a set of anchor segments distributed around a circumference of the central energizing mandrel, each having one or more wedge surfaces facing toward the central tool bore and corresponding to and engaging inclined surfaces of the central energizing mandrel. The tool is releasable by relative upward movement of a release sub against a release sub stop arranged within the central tool bore. A release mechanism houses one or more pre-loaded release spring members locked with a release locking mechanism. When unlocked the release spring members exert a retracting bias force on the central energizing mandrel in downward direction along the longitudinal axis relative to the set of anchor segments. This downward movement of the central energizing mandrel causes a radially inward movement of the set of anchor segments.

Abstract: A method to provide fractures in a formation includes providing a wellbore in the formation and providing a casing in the wellbore. The method also includes providing communication between an inside of the casing and the formation and initiating a fracture from the communication between the inside of the casing and the subterranean formation. The method further includes propagating the fracture with a fluid comprising mortar slurry. Prior to propagating the fracture with a fluid comprising mortar slurry, a fluid comprising acid is injected into the formation through the communication between the inside of the casing and the formation.

Abstract: A hybrid push and pull method for expanding a tubular in a wellbore utilizes an expansion assembly with a sealed and another, optionally expandable, cone, wherein during at least part of the expansion process the sealed cone is moved up through the tubular by a combination of push and pull forces and the push force is generated by pumping fluid at an elevated pressure into a space between the bottom plug and the expansion assembly. This allows staged expansion of the tubular in a hard rock formation and/or of a tubular surrounded by a hardened cement lining and/or of a pair of partially overlapping nested tubular ends.

Abstract: Provided is a method for reducing odors including the steps of admixing active agents and a diluting agent to liquid bitumen or to liquid crumb rubber modified bitumen. The active agents comprise 20 to 60 wt.-% of an aldehyde selected from alpha-hexyl cinnamaldehyde, 2-(4-tert.-butylbenzyl) propionaldehyde, 2-benzylidenheptanal, or mixtures thereof, 10 to 40 wt.-% of one or more alcohols having boiling point of at least 150° C., and 0.3 to 1 wt.-% compound selected from a compound comprising 10 carbon atoms and an hydroxyl functional group, an ester of a compound comprising 10 carbon atoms and an hydroxyl functional group, or mixtures thereof, calculated on the total weight of active agents. The bitumen and/or crumb rubber modified bitumen obtained according to the method, and the use thereof are also provided.

Abstract: An acid-generating fluid comprising a thermally activated strong acid precursor is provided in the method of the present invention. The thermally activated strong acid precursor comprises sulfur dioxide or a first precursor of a compound adapted to react to liberate sulfur dioxide, and an aldehyde and/or a ketone or a second precursor of a compound adapted to react to liberate an aldehyde and/or ketone. The acid-generating fluid is placed into a subterranean formation, where the first precursor and/or the second precursor are thermally activated, thereby liberating sulfur dioxide and the aldehyde and/or ketone. The sulfur dioxide and the aldehyde and/or ketone are reacted to form a thermally activated strong acid.
