Features

  • Advanced cementing tools enhance well integrity

    Justin Bowersock and C. O. “Doc” Stokley

    From swellable packers to port collars, one oilfield services company is tackling mechanical and non-mechanical cementing challenges around the world.

  • International global potential growing, but development lagging

    Pramod Kulkarni

    Oil and gas operators throughout the world are exploring for shale plays with the same fervor by which astronomers are scanning the universe for signs of life. If there’s life on Earth, shouldn’t there be life on some of the billions of planets out there? Applying the same logic, where are the Bakkens and Eagle Fords in the rest of the world?

  • Marine seismic acquisition at Scott Reef: Minimizing environmental impacts in a sensitive location

    Mark Taylor, Jeremy Fitzpatrick and Ralph Weiss

    Extensive bathymetric surveys and metocean work were critical for seismic coverage in a reef environment in Western Australia

  • Openhole gravel packing of fishhook wells with zonal isolation and uphill heel-to-toe packing

    Sateria Sulaiman, Rene Jansen, Manish Kumar, Raymond Tibbles, Nicholas Moses, Amirul Nordin, Joe Alexander and Samyak Jain

    An alternative method for gravel packing fishhook wells uses conventional service tool configurations and results in very low friction pressure during the treatment, making it applicable to wells with narrow frac/pore-pressure windows.

  • Regional Report West Africa

    Ian Lewis

    The region has one of the world’s leading oil and LNG sectors, with mega E&P projects coming onstream on a regular basis, despite a production decline in Nigeria, due to oil thefts and sabotage.

  • What’s new in well logging and formation evaluation

    Stephen Prensky

    Part 2: Wireline Cased-Hole Logging, Coring, and Wellsite Evaluation—New developments include pulsed-neutron logging, casing integrity, flow profiling, intelligent tracers, nanoparticle contrast agents; wireline coring and pressure coring, core preservation, QC/QA of special-core analysis; cuttings-based correlation, mud-gas analysis, applications of advanced mud-gas analysis.

Shale Technology Review

  • Drilling the unconventionals for maximum reservoir exposure

    Jim Redden

    Amid tight economics, shale enables drilling technology development in an unequaled spurt of creativity.

  • G&G advances critical for shale definition and efficient development

    Bill Pike

    Exploitation of unconventional resources, such as shale, calls for new exploration tools to address unique challenges.

  • Horizontal well fracturing: A state-of-the-art report

    Ali Daneshy

    Significant progress has been made in hydraulic fracturing over the last several decades, but several crucial factors remain to be addressed, particularly as pertain to horizontal sections.

    Shale Technology Review: New Products & Services

  • New shale technologies, best practices

    Pramod Kulkarni

    Horizontal drilling and multi-stage fracturing have been the technology enablers for shale gas and liquids exploration and production. In the early days, the operators thought this was all the technology they needed—drill down to the shale formation, kick off a horizontal lateral somewhere in the shale and start fracing. The results, of course, were inconsistent. Some wells produced at exceptionally high initial rates; others were low producers. Moreover, the wells were expensive to drill and produce.

  • Technology needs in North American shales require solutions

    Steve Jacobs

    A recent survey found a number of shale-related issues that operators and technology providers are concerned about. It also found a significant trend toward greater natural gas usage in high-horsepower applications.

  • Treatment is key to effective shale water management

    Russell Wright

    Water is, by far, the largest component of frac fluids, and is usually the most difficult to source, recycle and dispose. There are many ways to minimize the amount of water that must be handled, but its effective treatment for reuse or disposal is becoming an increasingly critical aspect of shale development.
