        Iran wants to increase its natural gas imports from Turkmenistan and will accept a higher price, according to Iranian Foreign Minister Manuchehr Motaki.

    • Journally Speaking

      • Well-contained drilling
        A lake in Central America is the latest focus in the International Continental Scientific Drilling Program.

  • Exploration & Development

    • Discovery size decreasing but revisions, start-ups buoy reserves
      No field with 1 billion boe recoverable is confirmed to have been discovered in 2005, but the world’s operators more than replaced the year’s production by bringing previously discovered fields on production and revising reserves upward in existing fields, IHS Energy reported.
    • Gulfsands sees potential in Syrian structure
      Gulfsands Petroleum PLC, Houston, has identified nine potentially productive zones in Paleozoic reservoirs in the sole existing wellbore on the large Tigris structure in 11,000-sq-km Block 26 in northeast Syria.
    • Range presses Virginia multipay gas drilling
      Range Resources Corp., Fort Worth, is pursuing coalbed methane and gas in shallow and deep tight formations with horizontal and vertical wells in southwestern Virginia.

  • Transportation

    • Fiber-optic monitoring focuses on bending, corrosion
      Long gauge-length fiber-optic sensors (FOS), effectively used in detecting pipe movement by monitoring any change in the neutral plane of the pipe from its initial reference state, can also measure any bending strains that occur due to pipe movement.

  • Supplement to Oil & Gas Journal

    • Advances in Drill Bit Technology

      • The Art of Makin’ Hole Shifts to New Levels
        If high oil prices weren’t enough to drive increased exploration and production activity in 2005, improved drilling technology was.
      • Roller Cones vs. Diamonds: A Reversal of Roles
        Throughout the history of drilling, “Heavy Metal” (not to be confused with the music genre) has been the preferred cutting element for grinding/crushing/chipping formations on literally the leading edge of a drilling device.
      • Synergy Leads to Bit Innovations
        Maybe it’s a better understanding of rock mechanics and hydraulics. Maybe it’s material science and manufacturing innovations.
      • Application and Formation Challenges Abound
        As exploration and development ventures into frontier drilling environments and new rig equipment, BHAs and operator capabilities push technology limits, drilling bits face a continual challenge to meet performance expectations in different applications and formations.
      • Choosing the Right Bit
        Drilling programs throughout the world are now more challenging in terms of depths, well profiles, and formation drillability (often determined by hardness and/or abrasiveness).
      • Technology Developments to Watch
        New materials, a better understanding of rock mechanics and hydraulics, extreme drilling environments, improvements in BHAs, high activity levels and unique applications have all driven ongoing drilling bit innovation.
