Abstract: A downhole shifting sleeve device includes a first segment and a second segment each including a housing, a sleeve, and a seat surface connected to the sleeve. Each seat surface is configured to engage a plug traveling through an inner bore of the device, which transfers the associated sleeve from a first position to a second position. The seat surface of the second segment is formed by a selective seat assembly. When the first sleeve is in the first position, the selective seat assembly is in a retracted position in which an inner diameter of the selective seat assembly is greater than or equal to an inner diameter of the second sleeve. When the first sleeve is in the second position, the selective seat assembly is in a deployed position in which the inner diameter of the selective seat assembly is less than the inner diameter of the second sleeve.

Abstract: An orientation system includes an upper sub, a lower sub, and an orienting sleeve for rotationally aligning the upper sub with a rotational position of the lower sub. The orienting sleeve includes a keyed upper surface configured to engage a keyed lower surface of the upper surface, and an inner faceted portion configured to engage an outer faceted portion of the lower sub. The orientation system further includes an upper sleeve configured for attachment to the orienting sleeve and the upper sub, and a lower sleeve configured for attachment to the orienting sleeve and the lower sub. The upper and lower sleeves secure the upper sub to the lower sub.
