7249500, Jul 31, 2007

Filed:

Feb 5, 2003

Appl. No.:

10/542119

Inventors:

Robert E. Dutton - Louisville CO, US
Christopher M. Russell - Cypress TX, US

Assignee:

Micro Motion, Inc. - Boulder CO

International Classification:

E21B 47/10

US Classification:

7315232

Abstract:

A measurement system () is disclosed comprising a Coriolis flow meter () and a control system (). A base fluid () is first flowed through the Coriolis flow meter. The Coriolis flow meter measures a density of the base fluid and transmits a base fluid density measurement to the control system. A proppant () is then added to the base fluid to create a fracture fluid (). The fracture fluid is then flowed through the Coriolis flow meter. The Coriolis flow meter measures a density of the fracture fluid and transmits a fracture fluid density measurement to the control system. The control system determines an amount of proppant in the fracture fluid based on the base fluid density measurement, the fracture fluid density measurement, and a density of the proppant.

Abstract:

Oligomerization catalyst and method for oligomerization using the catalyst. The catalyst comprises a single Zn(II) or Ga(III) metal ion center directly bonded to a support through a shared oxygen atom, the catalyst having at least one M-O bond which forms an active site for oligomerization. The method includes reacting one or more C2 to C12 olefins with the oligomerization catalyst at a temperature of about 200 C. or higher to provide an oligomer product comprising C4 to C26 olefins.

International Classification:

G06T 11/60

Abstract:

Systems, methods, and computer-readable media for operating a virtual environment are provided. The method can include receiving information associated with a thing in view of an augmented reality (AR) device. The thing can be a physical object or a virtual element, such as text on a screen or a web page. The method can further include identifying the object or thing based on the information, identifying virtual content associated with the object or thing, determining that the AR device is permitted to receive at least a portion of the virtual content, transmitting the virtual content to the AR device based on the determining, and causing the AR device to display the virtual content. The ability of a user to view the virtual content associated with the object or thing can further be limited by an authentication process or access level.
