Abstract:

Six wells will be utilized during operations to monitor reservoir parameters. Elmore #3 will be used for production. Magmamax #1, Woolsey 81 and possibly later in the program Magmainax #2 and #3 will be used for injection and Magmamax f4 and Elmore # 3, initially, will be used for observation.

I. Activities to be carried out prior to actual start-up of thermal test loop.

A. All wells will have temperature and pressure surveys taken.

B. Magmamax #3 will be flowed into a Baker tank to obtain baseline chemistry associated with the reservoir being produced from Magmamax 153. This information will not be an accurate determination of actual reservoir conditions in Magmamax #3 because considerable injected fluid has been put into Magmamax f 3 in the various small scale testing operations carried on in the past; however, a baseline of existing brine chemistry in the vicinity of the reservoir which is penetrated by Magmamax #3 will be desirable for monitoring future injection operations.

C. Magmamax #2 will be flowed into a Baker tank at the minimum rate possible to clean the well out and obtain an accurate sample of the produced waters to establish a baseline prior to injection operations on brine chemistry. The anticipated duration will be one to two hours depending on flow capabilities and the tank holding capacity. Since Magmamax 2 has not been previously used for injection purposes a good sample of actual reservoir conditions should occur rather rapidly.

D. Magmamax #1 will be produced through the by-pass to the brine pit until evidence is shown that the well is producing at a stabilized rate. It may be necessary to shut down the well and pump the brine pit to Magmamax #3 several times before stabilization occurs. E. Woolsey #1 will be produced on the same basis as Magmamax #1 untill stabilization has occurred.
