Publication number: 20100015612 


Abstract: This invention relates in general to characterizing hydrocarbon reservoirs and/or determining flow properties of fluids associated with the reservoir-including fluids introduced into the reservoir to provide for hydrocarbon extraction-using biological tags and real-time polymerase chain reactions for tag detection. In embodiments of the present invention, one or more biological tags may be added to one or more liquids associated with the hydrocarbon reservoir and subsequently one or more liquid samples may be taken from locations associated with the hydrocarbon and the presence of the one or more biological tag may be qualitatively and/or quantitatively tested for in the samples using real-time PCR.

Methods and systems for robust and accurate determination of wireline depth in a borehole 

Publication number: 20090248307 


Abstract: This invention relates in general to measuring depth of well-tools, such as logging tools or the like, in a borehole. Embodiments of the present invention may provide for disposing conducting areas along a wireline that may be used to suspend and move the well-tool in the borehole, where the conducting areas may be disposed along the wireline at predetermined locations. A reader may be located at a reference location and may read when a conducting area passes through the reference location and this information may be used to determine the depth of the well-tool in the borehole. Additionally, this invention provides for combining depth measurements from the conducting areas with measurements from odometer wheels in frictional contact with the wireline and/or time of flight measurements of optical pulses passed along a fiber optic cable coupled with the wireline to accurately and robustly measure the depth of the wireline in the borehole.

Methods and systems for robust and accurate determination of wireline depth in a borehole 



Patent number: 7458421 


Abstract: This invention relates in general to measuring depth of well-tools, such as logging tools or the like, in a borehole. Embodiments of the present invention may provide for disposing transponders along a wireline that may be used to suspend and move the well-tool in the borehole, where the transponders may be disposed along the wireline at predetermined locations. A reader may be located at a reference location and may read when a transponder passes through the reference location and this information may be used to determine the depth of the well-tool in the borehole. Additionally, this invention provides for combining depth measurements from the transponders with measurements from odometer wheels in frictional contact with the wireline and/or time of flight measurements of optical pulses passed along a fiber optic cable coupled with the wireline to accurately and robustly measure the depth of the wireline in the borehole.

Method and system for estimating the position of a movable device in a borehole 



Patent number: 7055601 


Abstract: A method is provided for estimating the position of a movable device in a borehole. The method comprises the steps of: (a) providing a prior location probability distribution associated with a first position of the device in the borehole, (b) providing a measurement of a putative distance moved by the device and/or a measurement of a characteristic of the surroundings of the device, the or each measurement being associated with movement of the device to a subsequent position in the borehole, and (c) calculating a posterior location probability distribution associated with the subsequent position, the posterior location probability distribution being conditional on the prior location probability distribution, and the or each measurement.

System and method for wellbore communication 



Patent number: 6993432 


Abstract: A method and system is disclosed for communicating information from a downhole location to the surface including a plurality of releasable vessels containing predetermined signal information affixed to the vessels prior to placement of the vessels downhole and indicative of the presence of at least one of three or more predetermined downhole conditions and a sensing and releasing system that senses the occurrence of the downhole condition, such as a simple threshold, and release the vessels in response to the sensing. The predetermined downhole condition can be characteristic of the fluid being produced in the borehole, such as water fraction, a certain level of mechanical wear or damage to downhole equipment such as bit wear, or the firing a one or more charges on a wireline deployed perforation tool.

System and method for wellbore communication 



Publication number: 20040204856 


Abstract: A method and system is disclosed for communicating information from a downhole location to the surface. A plurality of releasable vessels are positioned downhole, each containing signal information affixed to the vessels prior to placement of the vessels downhole. The signal information indicates the presence of at least one of three or more predetermined downhole conditions. A detecting system is positioned on the surface such that the signal information can be detected on one or more of the vessels. The predetermined downhole condition can be characteristic of the fluid being produced in the borehole, such as water fraction, a certain level of mechanical wear or damage to downhole equipment such as bit wear, or the firing a one or more charges on a wireline deployed perforation tool.
