OpportunityTitle: Havasupai Bar Four Well Evaluation and Rehabilitation
AdditionalInformationOnEligibility: This is a notice of intent to award, no competition is being sought.
Description: The Bar 4 well was completed in 1996. The well was drilled to a depth of 3,110 feet. A pumpjack was installed at that time for well testing. The well was equipped later that year with a permanent pumpjack (photo above). The pumpjack was removed in 1999 for temporary installation of an electric submersible pump and pressure transducer to test the well at a higher rate than possible with the installed pump. The original pumpjack was reinstalled afterward. In the spring of 2001, the USBR replaced the pump barrel which was found to be no longer functional due to corrosion and deterioration. It appears the last time the pump has been operated since then was in May 2002 for collection of a water sample. Several other water samples have also been collected since the well was installed. NRCE inspected the well in 2007 and in 2013. The pumpjack appears to be serviceable and in good condition. The condition of the pump barrel is unknown, and due to infrequent operation, may have suffered corrosion and deterioration since its last operation. It is therefore necessary to operate the pump in order to identify any problems that need to be repaired prior to placing the system in full-time operation. There is currently no source of power at the site to run the pump motor. The Havasupai Tribe propose to conduct a service and test run of the Bar 4 well before moving forward with the proposed development of the Bar 4 residential community and to enable routine sampling of the well. The approach for rehabilitation of this well is broken into five tasks. The outcome of each task dictates the necessity of and requirements for subsequent tasks. The tasks are: Task 1 Startup test and operation of well Task 2 Pumpjack service (surface equipment) Task 3 Power Supply Task 4 Water analysis Task 5 Report
