Patent number: 8985211Abstract: Methods of drilling with a wellbore fluid may include pumping the wellbore fluid with an oxidative degradable polymer into a wellbore with and an inactivated oxidant; forming a filtercake in a downhole environment, allowing some of the fluid to filter into a subterranean rock formation to produce a filtercake containing the oxidative degradable polymer and inactivated oxidant; and removing the filtercake formed by the wellbore fluid from the wellbore walls by exposing the filtercake with a breaker fluid comprising an aqueous fluid, and at least one iminodiacetic acid or a salt thereof.Type: GrantFiled: March 16, 2010Date of Patent: March 24, 2015Assignee: M-I L.L.C.Inventors: Andrew G.

Patent number: 8932999Abstract: A method of cleaning a wellbore prior to the production of oil or gas is disclosed, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake. The method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid includes an aqueous fluid, and imino diacetic acid or salt thereof. Optionally an acid buffering agent, and a weighting age are also included. The breaker fluid is formulated such that after a predetermined period of time and the filter cake present in the wellbore or on the wellbore face is substantially degraded. Other methods may also include drilling the wellbore with a water-based drilling mud that forms a water-based filter cake, wherein the method may include the steps of circulating a breaker fluid into the wellbore, where the breaker fluid may include an aqueous fluid, and an iminodiacetic acid or a salt thereof.Type: GrantFiled: February 18, 2008Date of Patent: January 13, 2015Assignee: M-I L.L.C.Inventors: Andrew G. K. Jones, Mark Luyster, Raul Navarro

Patent number: 8706548Abstract: One methodology in accordance with the disclosure is a computer-implementable methodology for quantitatively assessing the impact of paid search advertising on the total visits (paid and organic search-based visits) from search engines and utilizing this assessment to improve search engine marketing performance. The methodology relies on the computation of a synergy score for each search engine keyword of interest or coefficients in a synergy equation. Once computed, the score can be used to repeatedly compute the total return on advertising spend (ROAS) and other performance metrics on a go-forward basis without the time lag inherent in computing the synergy score itself. The methodology includes specific computer-implementable methods for improving search engine marketing performance based on the total (paid plus organic) performance metrics.Type: GrantFiled: March 15, 2013Date of Patent: April 22, 2014Assignee: Covario, Inc.Inventors: Matthias Blume, Raul Navarro-Cantu, Craig MacDonald, Dema Zlotin, Russ Mann
