Patent number: 7059407Abstract: The invention discloses methods of, as well as apparatus and systems for, perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore by deploying within said wellbore a bottom-hole assembly (“BHA”) having a perforating device and a sealing mechanism, wherein pressure communication is established between the portions of the wellbore above and below the sealing mechanism. The BHA is positioned within the wellbore such that the sealing mechanism, when actuated, establishes a hydraulic seal in the wellbore to positively force fluid to enter the perforations corresponding to the interval to be treated. A treating fluid is pumped down the wellbore and into the perforations created in the perforated interval. The sealing mechanism is released, and the steps are repeated for as many intervals as desired, without having to remove the BHA from said wellbore.Type: GrantFiled: April 6, 2005Date of Patent: June 13, 2006Assignee: ExxonMobil Upstream Research CompanyInventors: Randy C.

Patent number: 6394184Abstract: The invention provides an apparatus and method for perforating and treating multiple intervals of one or more subterranean formations intersected by a wellbore by deploying a bottom-hole assembly (“BHA”) having a perforating device and at least one sealing mechanism within said wellbore. The BHA may be deployed in the wellbore using a tubing string or cable; or alternatively, the BHA may be deployed using a tractor system attached directly to the BHA. The perforating device is used to perforate the first interval to be treated. Then the BHA is positioned within the wellbore such that the sealing mechanism, when actuated, establishes a hydraulic seal in the wellbore to positively force fluid to enter the perforations corresponding to the first interval to be treated. A treating fluid is then pumped down the wellbore and into the perforations created in the perforated interval.Type: GrantFiled: February 12, 2001Date of Patent: May 28, 2002Assignee: ExxonMobil Upstream Research CompanyInventors: Randy C.
