Publication number: 20130160998Abstract: Compositions of lost circulation materials are provided that are useful for identifying the location of fluid loss in a wellbore. The compositions include additives which enhance a property of the composition such that they can be detected by an LWD or MWD tool capable of measuring the property when the composition is deployed in a region of loss, and can be distinguished by the LWD or MWD tool from the formation and mud fluid. Methods are also provided for using the composition to detect the location of fluid loss and for controlling the loss of fluid from the wellbore. The methods involve deploying the compositions in loss regions by adding the compositions to drilling mud, and measuring a property of the compositions using an LWD or MWD tool.Type: ApplicationFiled: December 23, 2011Publication date: June 27, 2013Inventors: Francois M. Auzerais, Dzevat Omeragic, Slaheddine Kefi, Dean M. Homan, John P. Horkowitz, Benoit Vidick, Dominique Malard, Robert Utter, Andrew Hawthorn

Patent number: 8394464Abstract: A method of lining tubing within a wellbore comprises applying a polymerisable fluid composition containing a photoinitiator to the interior surface of that tubing and initiating polymerisation of the composition by exposing it to actinic radiation, suitably light or ultraviolet with wavelength 250 to 800 nm. The composition is preferably stable against heat but polymerises quickly when exposed to the actinic radiation. The composition may be spread onto the tubing and exposed to actinic radiation as soon as it has been spread into a layer, suitably with a tool which skims the tubing surface with applicator pads for dispensing and spreading the composition, immediately followed by exposing the spread composition to actinic radiation. A second option is that the composition is provided as a sleeve which is expanded against the tubing, exposure to actinic radiation preferably then being achieved using light guides or light emitting diodes within the sleeve.Type: GrantFiled: March 31, 2009Date of Patent: March 12, 2013Assignee: Schlumberger Technology CorporationInventors: Louise Bailey, Benoit Vidick, Paul Way, John Cook

Publication number: 20110257887Abstract: Monitoring of a wellbore which penetrates a reservoir is carried out by providing tracer material at one or more subterranean locations within or proximate the wellbore, so that tracer may enter the flow and be present in flow from the wellbore; repeatedly taking samples from the flow from the wellbore, and analyzing the samples for the presence of tracer, in the vicinity of the wellsite. Taking samples from the flow will generally be done at the surface and may be done by automatic equipment controlled by a programmed computer. The computer may be programmed to take action, such as operating a valve within the well, in response to detection of tracer. Sampling repeatedly and analyzing on site can provide information in something close to real time and thus integrates the use of tracers into an overall process of monitoring and control.Type: ApplicationFiled: April 20, 2010Publication date: October 20, 2011Applicant: Schlumberger Technology CorporationInventors: Iain Cooper, Matthew Miller, Benoit Vidick, Gary Tustin

Patent number: 8002049Abstract: A method of preventing or treating lost circulation during the drilling of a well comprises the addition, at concentration ranging between about 0.5 and 6 pounds per barrel, of water-dispersible fibers having a length between about 10 and 25 mm, for instance glass or polymer fibers, to a pumped aqueous base-fluid including solid particles having an equivalent diameter of less than 300 ?m. The base-fluid with the solid particles can be the drilling fluid or a small-volume pill specially pumped for curing lost circulation.Type: GrantFiled: December 3, 2007Date of Patent: August 23, 2011Assignee: Schlumberger Technology CorporationInventors: Roger Keese, Trevor Munk, Raafat Abbas, Erik Nelson, Benoit Vidick

Publication number: 20110127034Abstract: When preparing a settable slurry such as a cement slurry for cementing an oil well, cement or other solid powder is mixed with water and a set retarder. In order to be able to run a convenient and rapid check on the concentration of retarder after dilution at the site of use, a tracer material is mixed with the retarder in known amount during manufacture. The tracer is chosen to enable its concentration to be determined analytically after dilution at the site of use, thereby providing a way to determine the concentration of set retarder after such dilution. The tracer may be a redox-active material and its concentration may be determined by voltammetry. Tracer may likewise be mixed with additives other than set retarder.Type: ApplicationFiled: November 30, 2009Publication date: June 2, 2011Applicant: Schlumberger Technology CorporationInventors: Benoit Vidick, Robert Seth Hartshorne, Nathan Lawrence, Carl Johnson, Glen Monteiro, Jonathan Woodrow
