  • Drilling Activity in the Mid-Continent Region

    Since October, rig counts in the Fayetteville have been stable at around 30 units.  This trend is likely to continue since a majority of capital going into the play is directed at development drilling.  Southwestern Energy has been the most active operator with an average of 13 rigs in recent months.  ExxonMobil’s XTO subsidiary and Chesapeake have also been active in the play.  Its subsidiary contractor, Desoto Drilling, performs most of Southwestern’s drilling.  Other contractors active in the play include Union Drilling, Nomac and Keen Energy Services.

     

    Persistently low natural gas prices have weighed on drilling activity in the Arkoma Woodford, the legacy Woodford play, in recent months.  Since yearend, the number of rigs drilling in the play has fallen by four to 18 rigs.  On a positive note, rig levels may find support now that two majors, BP and ExxonMobil, are some of the most active in the play.  Cactus has been the most active contract driller in recent months with seven rigs.

  • Granite Wash Play Overview


    From the July 2010 issue of The Land Rig Newsletter:


    The Granite Wash play is not developing in a single rock formation like the Barnett or Woodford shale, but in multiple sands within a Pennsylvanian-age sediment package up to 4,000 ft thick. This sediment eroded off the granitic Ouachita Mountains into the Anadarko Basin, hence the play’s name. The play extends across six counties in north Texas: Gray, Hemphill, Lipscomb, Ochiltree, Roberts, and Wheeler; and six in Oklahoma: Beckham, Custer, Dewey, Ellis, Roger Mills, and Washita. Sand packages that are being developed include the Cleveland, Oswego, Red Fork (upper and lower), and Atoka (A and B). Unlike some shale plays that apply a standard well plan across many wells, a standard well plan in this play can only be used in a relatively small area when drilling for any specific sand package. This means that economies of scales for drilling are limited. Rigs will drill vertically to sands at TVDs varying from 8,000 ft to 13,000 ft before going horizontal into a productive zone. Laterals of about 5,000 ft are not uncommon. Operators are still learning which sands produce the best, and the best way to develop the most ...

  • Gas Shale Plays Remained Steady

    As has been the case for much of the year, gas shale plays were the main story at the end of the year. Even as the traditional (>5,000 ft) U.S. rig count slipped in sequential biweekly periods for the first time since end-September, the tally of rigs drilling in the five major gas shale plays remained fairly steady as of December 31.

     

    In November, the collective rig count for the five major gas shale plays topped 300 and since then has stayed near that milestone, matching a level last seen in January 2009. The dramatic year-long gains in the Haynesville and Marcellus have been noted, as has the steady drilling pace in the Fayetteville and Woodford in second half 2009. Meanwhile, the Barnett—hardest hit among gas shales in the downturn—has quietly extended a rig-growth trend since the end of summer. The play now has 78 active rigs, a 142% increase in rig count over the past 18 weeks.
