The Reisdorf Unit #1 in the northern portion of the company’s Java Field has been successfully re-completed, fracked and tested in the Marcellus Shale at a depth of 1,368 to 1,389ft.
Although the frac was modest and highly focused due to the current regulatory maximum of 80,000 gallons of water that can be used for fraccing, the well has responded very well. The well was shut in for several days prior to testing, the company said.
The shut-in pressure exceeded 900psi which is well above engineering estimates for this depth and is a very positive indicator for the Marcellus in this area. Even though frac water is still being recovered, the well flowed at a rate of 144mcf per day at a stabilized flowing tubing pressure of 140lbs during a 4 hour test on a 16/64ths choke.
Adjusting for the effect of the frac water recovery, the calculated open flow rate for this flowing tubing pressure and choke size is 220 mcf per day.
Well data also indicates at least two viable shale zones uphole from the Marcellus as well as good potential in the Onondaga, a limestone just below the Marcellus.
These additional zones will be the subject of additional testing and possible development as the company expands its development program. Operations have begun for the re-completion of the Ludwig #1. The Ludwig #1 is in the southern portion of the Company’s Java Field and will be the second well to be tested in the field.
