  • Patent number: 8882428
    Abstract: A transfer system includes a conduit, a support, and a conveyor. The conduit has a first end and a second end and is configured to transfer dry material from the first end to the second end. The support is in contact with at least a portion of the conduit and is configured to maintain the second end of the conduit in a desired position relative to the first end of the conduit during transfer of the dry material from the first end to the second end. The conveyor is adjacent to the conduit and is configured to deliver the dry material to the first end of the conduit from a floating vessel configured to transport the dry material.

  • Publication number: 20090007650
    Abstract: A method for wellsite verification of properties of a fluid may include providing a fluid delivery system at the wellsite; providing at least one reference meter at the wellsite; and measuring the property of the fluid within the fluid delivery system, using the reference meter. The measuring step may be performed prior to or during dispatch of the fluid into a well bore. The reference meter may be a high precision meter. An apparatus for wellsite verification of at least one property of at least one fluid may include a fluid delivery system and at least one reference meter for measuring the property of the fluid within the fluid delivery system. The fluid delivery system and the reference meter may both be located at the wellsite. A trailer may support the fluid delivery system and the reference meter.
