Measure or Goal* Period to Date Next Week
Install Vertical Relief Wells ea. 4 4 0 4 0All four RW wells were completed as of March 22, 2008. Currently various performance testing work is underway, while evaluations are being made to provide the proper pumps for the conditions and the recharge.
Install Perm. Dewatering Pumps and Infrastructure ea. 44 44 0 44 0
Have fully satisfied the requirement to have at least 37 pumps in by Feb. 15. and have installed pumps in all wells as identified in the Dewatering Work Plan (which was submitted on Jan. 14). Freezing has limited the uptime of the pumps to this date. However, with warmer weather on the way, emphasis will now be placed on increasing uptime of pumps and working toward a fully-operation field.
Install 4-inch HDPE Liquid Discharge Line l.f. 3200 3000 0 3000 0 Have fully satisfied the requirement for a minimum 37 gas wells required by Feb. 15.
Install 2-inch HDPE Air Supply Line l.f. 10500 10300 0 10300 0 Have fully satisfied the requirement for a minimum 37 gas wells required by Feb. 15.
Install and Test Compressors ea. 3 3 0 3 0Two new compressors are in place and in service, meeting the F&O required schedule of Jan. 31. In addition, a third new compressor was put into service on April 8 to provide addirional, reliable air supply to the pneumatically-powered gas well pumps.
Relocate Flares from Top of Landfill ea. 1 1 0 1 0
One flare was relocated from the top of the landfill to a new pad on the north side of the landfill on April 9. The site has found that adequate control can be realized with three flares (rather than the four flares previously used). Therefore, relocations are complete for now.
Install New Gas Wells ea.32 (original goal was
10)32 0 32 0 Drilling of planned new gas wells was completed on April 25. The well drilling rig was
demobilized.
Replace Compromised Wells ea.25 (original goal was
12)19 2 21 0
The gas well drill rig has been demobilized. The remaining four gas wells need special materials and will be completed, possibly in May, after the materials arrive and the drill rig can remobilize.
Install Perm. Dewatering Pumps in New and Replacement Gas Wells ea. 25 9 4 13 4 Water levels obtained in newly-installed gas wells indicates that several of the new wells
require pumps per the objective of the Dewatering Plan. This process is ongoing.
Install 4-inch HDPE Liquid Discharge Line for new gas wells l.f. 3000 1200 600 1800 100
Assessments are being made to determine if the new and replacement wells need a pump after the first liquid level monitoring event following installation. If a pump is needed, the air and liquid conveyance lines will be promptly installed.
Install 2-inch HDPE Air Supply Line for new gas wells l.f. 5000 1200 600 1800 100 See above
Measure Achievable Drawdown ea. 124 0 0 0 0This process is scheduled to start after new and replacement wells are in place and after the pumping system has been operating well. Currently, this task is scheduled to begin May 20.
Establish Baseline Flow ea. 1 0 0 0 0 This will be performed after measuring achievable drawdown and is estimated to be completed July 28.
* The estimate of "required" or "goal" items may change as project progresses.
