Oklahoma’s
Woodford Shale
Oklahoma’s Woodford Shale The heaviest drilling in the
Woodford play is centered on the western end of the Arkoma
Basin in southeastern Oklahoma. But the play has expanded as
far west as Canadian County in the Anadarko Basin and as far
south as Marshall County in the Ardmore Basin. Some wells
have produced as much as 10 Mmcfd during the first week, but
average initial production is more in the five to six Mmcfd
range. One characteristic that makes the Woodford work is
that it is silica rich, making it brittle. This contributes
to both natural fracturing and success with multi-stage
fracs. Newfield Exploration Co, the predominant player, is
optimizing

drilling and completion operations, pushing development costs
down to the $2/Mcf range, or even lower
with longer horizontal laterals. Newfield spaces its
laterals 660 feet apart with lateral length extending as far
as 5,000 feet. Laterals are fracd in approximately 500 feet
stages. 3-D seismic is an essential enabling technology. It
helps operators avoid natural fractures that extend into
water-bearing formations and enables them to stay in zone
when laterals cross significant fault throws.

Economic Ranking of
New Gas Supply
In April Ziff Energy Group (Ziff)
announced completion of an eight-month study that analyzed
the full-cycle cost6s of new/marginal natural gas supply
from two dozen North American gas areas. These areas
represent about 90% of new/marginal gas. The analysis was
broken down into six primary groups: conventional, CBM,
tight gas, shale gas, offshore & yet to arrive Frontier, and
LNG. For many gas basins, the study estimates full cycle
costs for several play types. For shale gas, full cycle
costs are compared for Barnett, Woodford and Fayetteville.
Ziff notes that the study will help operators prioritize
which gas basins they should increase their activity in.
With information drawn from multiple sources, interviews,
third party objectivity and Ziff’s 25-year track record, the
findings at least warrant serious consideration. Further
information on the study can be found online at

O&G Production
in Kansas
Total oil
production in 2007 was 36.6 million barrels, up 0.9 million
barrels from 2006. Producers are reworking wells, applying
dollars and technologies to boost production in mature
fields. 3-D seismic is also playing a strong role in finding
new fields. Although the Hugoton gas area still dominates
state gas production, Wilson county in the southeast moved
into the top 10 gas producing counties due to coalbed
methane production. Other southeast Kansas counties rose in
the standings. Cherokee Basin gas production now ranks third
among gas fields in the state. Excerpted from Kansas

OERB’s Petro
Tech Program
OERB’s
PetroTech Program The Oklahoma Energy Resources Board (OERB),
in collaboration with Francis Tuttle Technology Center of
Oklahoma City and with strong support from industry,
developed the PetroTech Certification Program. Goal is to
provide individuals with the knowledge and certification to
enter the market as engineering, geological or land
technicians. Students, who must have a high school degree or
GED equivalent to enter the program, must complete 14
modules. Modules vary in length from four to six weeks and
involve night classes two nights a week. The program costs
about $3,000. Module topics include
-
Introduction to the O&G Industry
-
Petroleum Business Applications, EXCEL (multiple levels)
