A well completion method can comprise, in a single trip into a wellbore, the following steps being performed for each of multiple zones penetrated by the wellbore: abrasively perforating the zone with a tubing deployed perforating assembly, fracturing the perforated zone with flow from surface via a well annulus, and then plugging the fractured zone with a removable plug substance, the perforating assembly displacing in the wellbore while the fractured zone is being plugged. Another well completion method can comprise, in a single trip into a wellbore, the following steps being performed for each of multiple zones penetrated by the wellbore: perforating the zone using an abrasive perforator, then displacing the perforator in the wellbore away from the earth's surface, then fracturing the zone, and plugging the fractured zone with a flowable plug substance.

Well completion

A method for fracturing a wellbore in a formation, including positioning one or more bidirectional rotary sleeves on tubular members into the wellbore; engaging a unidirectional rotary source in a first position with a first bidirectional rotary sleeve of the one or more bidirectional rotary sleeves; operating the unidirectional rotary source to rotate the first bidirectional rotary sleeve in a first rotational direction to open at least one port in the first bidirectional rotary sleeve for providing an open fluid pathway between the first bidirectional rotary sleeve and the formation; pumping fluid through the tubular members and through the opened port to fracture the formation; engaging the unidirectional rotary source in a second position with the first bidirectional rotary sleeve; and operating the unidirectional rotary source to rotate first bidirectional rotary sleeve in a second rotational direction to close the at least one port in the first bidirectional rotary sleeve.

Apparatus for creating bidirectional rotary force or motion in a downhole device and method of using same

A tubing conveyed tool for use in perforating a well bore utilizing abrasive perforating techniques. The perforating tool is particularly useful in non-vertical wells. The perforating tool is designed to permit running and setting a bridge plug, and then perforating the well bore without requiring the removal of the tool string. An eccentric weight bar can also be used to allow for directional perforating in non-vertical wells. The eccentric weight bar uses gravity to cause the bar to rotate to a predetermined position.

Methods and devices for one trip plugging and perforating of oil and gas wells

A downhole bidirectional apparatus, including a first engagement section; a second engagement section having a rotary device; a third engagement section; and a rotary source having a first rotary member and a second rotary member, the first rotary member disposed about the second rotary member, the first rotary member connected to a first gripping member and the second rotary member connected with a second gripping member, wherein the rotary device is rotatable in a first rotational direction when the second gripping member is engaged with the third engagement section and the first gripping member is rotatably engaged with the second engagement section, and wherein the rotary device is rotatable in a second rotational direction when the second gripping member is engaged with the second engagement section and the first gripping member is engaged with the first engagement section.
