Abstract: A method of the invention prepares a hydrocarbon-bearing formation for stimulation. A bottom hole assembly comprising a plug and a perforation tool connected to a wireline is lowered into the wellbore. Acid is injected into the wellbore such that the acid is in direct contact with the perforation tool, wireline and casing of the wellbore. The plug is positioned downhole beyond a location where a first perforation area is to be made in the casing. The perforation tool is activated creating the first perforation area. The acid then contacts the first perforation area and cementitious debris generated from the casing being perforated. The perforation tool is next moved up-hole to a second location and the casing is again perforated to create a second perforation area. The acid also contacts the second perforated area and cementitious debris generated from the perforated casing. The perforation tool is lastly removed from the wellbore.

Abstract: A method of the invention prepares a hydrocarbon-bearing formation for stimulation. A bottom hole assembly comprising a plug and a perforation tool connected to a wireline is lowered into a wellbore having a casing. An acidic composition is injected into the wellbore; wherein a spacer separates the acidic composition from said bottom hole assembly, but the acidic composition is in direct contact with both the wireline and casing. The spacer may be existing water in the wellbore or water injected into the wellbore. The plug is positioned downhole beyond a location where a first perforation area is to be made in the casing. The perforation tool is activated creating the first perforation area. The acid then contacts the first perforation area and cementitious debris generated from the casing being perforated. The perforation tool is next moved up-hole to a second location and the casing is again perforated to create a second perforation area.

Abstract: An ember and flame resistant resettable automatic soffit vent includes a tray with ventilation openings formed in its floor. A mesh screen resides on the floor of the tray spanning the ventilation openings. A flat slide resides atop the screen and also has ventilation openings that match those of the tray. The slide has an open position wherein its ventilation openings align with those of the tray to allow airflow through the vent and a closed position wherein its ventilation openings are misaligned with the ventilation openings of the tray to close off airflow through the vent. The vent can be manually moved between its open and closed positions and one or more tension springs and a thermal link assembly cooperate to move the slide to its closed position if the vent is exposed to a high temperature cause by a fire very near a home.

Abstract: Systems and methods for processing erasure requests are provided, namely requests from users to have their user data erased from a system. The system maintains user data in multiple components which may not be in communication with each other. With the provided system, certain entities, referred to herein as erasure control entities, are informed of details of received erasure requests, and are given the opportunity to provide input on whether they should be executed or note. For example, one erasure control entity, such as a credit card server, may not want an erasure request executed for a user with a large outstanding debt, while another erasure control entity, such as a legal component, may be unaware of this and may not be concerned with the erasure request being executed. The system and method ensure that erasure requests are not executed in situations that are premature or inappropriate.
