production were conservatively calculated
from early-time production decline curve
analysis at approximately 12.0 BCF-13.5
Bcf. At six months of production, the
Sycamore well was still in linear flow,
making it difficult to accurately estimate
EUR using rate transient analysis. Therefore, numerical fracture modeling was
used to help calibrate an analytical model
and provide an estimate for the end of
linear flow. The gas EURs calculated
from the analytical and numerical modeling then were cross-referenced with the
EUR calculated from the decline curve
analysis. The EURs from the modeling
and the decline curve matches are in
agreement and confirm the well's strong
production potential.
The overall production results are encouraging, with this Sycamore well
demonstrating production performance
that is equal to or better than either the
Meramec or Woodford formations. The
performance of the well appears to be a
good indicator for the Sycamore formation's high degree of potential in the area
of Grady and Stephens counties.

Everything for Oilwell Cementing

but the Cement!

MULTIPLE STAGE
CEMENTING COLLAR

This tool is used to effectively cement upper
sections of the casing string after displacing
cement around the lower section. The tool provides a means of opening and closing port
holes for cement displacement and positive
containment of the cement after displacement.
All internal parts are easily drilled, and are
firmly held from rotating during drilling. The
port closing sleeve is positively locked in
position after cementing.
When running the collar, it is advisable to place
a casing centralizer above and below and to
run a cementing basket below the cementing
ports. After running the collar to setting depth,
the lower section is cemented in the conventional
manner except the cement is displaced with
the flexible cementing plug furnished with the
collar. This is bumped against the shut-off
baffle which is also furnished. A slight pressure
build-up of 300-400 psi will assure plug is
seated in baffle. The port holes in the multiple
stage cementing collar are opened for doing
the second stage by dropping the trip bomb
and applying approximately 800-1000 psi pressure. The second stage is displaced with the
closing plug which is also furnished with the
tool. When the closing plug bumps approximately
800-1000 psi pressure will close the port holes.
