20110083503 | Methods and Apparatus for Designing a Cement Composition - A method comprising preparing a baseline cement slurry comprising a cement, water, and one or more additives, placing a sample of the baseline cement slurry into a sample container having a vertical height, and measuring time of flight of energy through the sample at one or more locations along the vertical height to determine a settling property of the baseline cement slurry. A method comprising providing a settling test apparatus comprising a column having a vertical height and at least one pair of transducers positioned opposite each other with the column there between, placing a cement slurry sample within the column, and measuring time of flight of ultrasonic energy through the sample at one or more locations along the vertical height to determine a settling property of the cement slurry. | 04-14-2011 |
20140216742 | FLOATING APPARATUS AND METHOD FOR FABRICATING THE APPARATUS - A floating apparatus for use in a casing string is provided. The apparatus includes an outer sleeve having a valve centrally positioned therein. A cement body is affixed to the check valve and the housing by use of a bonding material. | 08-07-2014 |
20140326073 | Cement Testing - Systems and methods provide for testing a cement by applying force in a first direction until the first portion of the cement sample fails in compression or tension; and applying force a second direction opposite the first direction until the second portion of the cement sample fails in tension or compression. | 11-06-2014 |
20140374097 | Wellbore Servicing Compositions and Methods of Making and Using Same - A method of servicing a wellbore in a subterranean formation comprising preparing a wellbore servicing fluid comprising a sealant material, helical fibers and a base fluid, placing the wellbore servicing fluid in the wellbore and/or subterranean formation, and allowing the wellbore servicing fluid to set therein. | 12-25-2014 |

20080262187 | Blends of Diamines Having Reduced Color - This invention provides a blend which comprises (i) at least one aromatic primary diamine, with which has been blended a color-minimizing amount of at least one N,N-dmydrocarbylhydroxylamine, wherein the aromatic primary diamine is in the form of one benzene ring having two primary amino groups on the ling, which amino groups are meta or para relative to each other, and in which each position ortho to a primary amino group bears an alkyl group, and (ii) at least one aromatic secondary diamine having a Gardner color number no more than about 7, wherein said aromatic secondary diamine either is in the form of one benzene ring having two secondary amino groups on the ring, or is in the form of two benzene rings connected by an alkylene bridge and having one secondary amino group on each ring. Optionally, at least one N,N-dihydrocarbylhydroxylamine has been blended with the aromatic secondary diamine. | 10-23-2008 |
