Publication number: 20090248307Abstract: 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.Type: ApplicationFiled: June 11, 2009Publication date: October 1, 2009Applicant: Schlumberger Technology CorporationInventors: Harry Barrow, Ashley Johnson, Michael Barrett, Charles Jenkins, John Corben, Gary Rytlewski

Publication number: 20090151938Abstract: A method for preparing a formation surrounding a wellbore to bear hydrocarbons through a borehole is disclosed. In one step, a bottomhole assembly is inserted into the borehole. The formation is drilled with the bottomhole assembly. The formation may be characterized with logging tools, probes, sensors, seismic system and/or the like to create first information. One or more fractures are placed in the formation without removal of the bottomhole assembly from the wellbore. Further, continuous drilling of the formation is performed with the bottomhole assembly after/during placing the fractures. Further characterizing of the formation with the probes, sensors/systems or the like is performed to produce second information. Another fracture is placed with feedback from the second information. Repeating the drilling, characterizing and placing of fractures as necessary during the formation preparing process.Type: ApplicationFiled: December 18, 2007Publication date: June 18, 2009Inventors: Don Conkle, Ashley Johnson, J. Ernest Brown, Trevor McLeod, Matthew Miller, Philip Sullivan, Dean Willberg

Publication number: 20090145660Abstract: A method for fracturing a wellbore while drilling a wellbore includes inserting a drill string into a wellbore. A fluid is pumped into at least one of an interior passage in the drill string and an annular space between a wall of the wellbore and the drill string. At least one of a pressure and a temperature of the fluid proximate a lower end of the drill string is measured and the measurements are transmitted to the surface substantially contemporaneously with the measuring. At least one of a flow rate and a pressure of the fluid is controlled in response to the measurements to selectively create fractures in formations adjacent to the wellbore.Type: ApplicationFiled: December 5, 2007Publication date: June 11, 2009Applicant: Schlumberger Technology CorporationInventors: ASHLEY JOHNSON, Benjamin P. Jeffryes, J. Ernest Brown

Patent number: 7458421Abstract: 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.Type: GrantFiled: December 14, 2005Date of Patent: December 2, 2008Assignee: Schlumberger Technology CorporationInventors: Harry Barrow, Ashley Johnson, Michael Barrett, Charles Jenkins, John Corben, Gary Rytlewski

Publication number: 20070270367Abstract: Group I intron-derived ribozymes can be modified to perform a reaction called trans insertion-splicing (TIS) where the ribozyme binds two exogenous RNA substrates and inserts a sequence from one directly into the other. Reaction products are stable, with no visible loss at extended times. The ribozyme recognizes the two substrates primarily through base pairing and utilizes an ?G on the ribozyme and a 3?-G on the sequence being inserted. The internal guide sequence of the ribozyme is utilized to sequentially bind both substrates, forming independent P1 helices. The reaction can also be performed without a first substrate, where the ribozyme is made with the insert sequence appended to its 3? end so as to perform a single substrate insertion targeted to any RNA sequence.Type: ApplicationFiled: January 16, 2007Publication date: November 22, 2007Applicant: University of Kentucky Research FoundationInventors: Stephen Testa, Ashley Johnson
