Filed:

Feb 5, 2003

Appl. No.:

10/542119

Inventors:

Robert E. Dutton - Louisville CO, 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.
