  • FLOOD-RESISTANT WEEP HOLE APPARATUS, SYSTEMS, AND METHODS
    Publication number: 20190085556
    Abstract: This disclosure provides for a valve assembly for regulating the flow of fluid through a weep hole, including a flow regulator positioned within the weep hole. The flow regulator has an open position where fluid is allowed to flow through the weep hole, and a closed position where fluid is prevented from flowing through the weep hole. Also provided is a building having a plurality of flow regulators positioned relative to external sheathing of the building to regulate flow between a wall cavity of the building and an external environment. Additionally, a method for regulating the ingress and egress of fluid through external sheathing of a building is provided. The method includes positioning a plurality of flow regulators relative to external sheathing, and regulating flow between the wall cavity and an external environment using the flow regulators.

  • Method for borehole measurement of formation properties
    Patent number: 7310580
    Abstract: The present invention is a method of estimating formation properties by analyzing acoustic waves that are emitted from and received by a bottom hole assembly. A bottom hole assembly may be deployed in a borehole to estimate formation properties. From the bottom hole assembly, a source signal may be emitted and at least one signal may be received by one or more receivers in the bottom hole assembly. Analysis of the frequency dependent characteristics of the received signal allows the estimation of the formation properties of interest, including pore pressure. The formation properties of interest may be used to monitor a wellbore pressure safety margin and to optimize drilling and weight.
