New Cost-Effective P&A Technique Workshop
The Department of Energy National Energy Technology Laboratory in cooperation with the Osage Nation, and Cementing Solutions, Inc. is conducting a workshop to demonstrate a new plugging technique on September 18, 2001 at 9:00 a.m. The workshop will begin at Osage Tribal Headquarters in Pawhuska, Oklahoma and proceed to the wellsite where Cementing Solutions, Inc. will demonstrate a simple, fast, and economical way to plug and abandon wells.
Technology
Cementing Solutions Plugging Process simplifies the plugging
process while maintaining sound engineering principles and design
processes. The method involves filling the entire wellbore with
cement or placement of discrete plugs in the casing. The use
of common construction cement equipment eliminates the need for
complex mixing equipment, high-pressure pumping equipment, and
a workover rig.
When the mixed slurry is transported to the location, it is
discharged from the ready mix truck into a holding tank and transferred
to the well via a low-pressure pump. Once in the well, the increased
hydrostatic pressure exerted by the cement column forces the
well fluid into the formation.
Design of the cementing treatment includes analysis of the well
conditions to determine if the method is appropriate for a candidate
well. Cement volumes, placement rates and times, casing hardware
and other operational needs are determined. The treatment is
monitored throughout mixing and placement to confirm that operations
are executed as designed.
