Thanks for the quote from the Beach report

"The Paralana-2 (Beach 21%) geothermal well
is currently being flow tested and controlled
at approximately 2 barrels per minute to
enable slow heating of the wellbore. Flow
will be monitored from the well over
approximately the next two weeks. Results
will be communicated after this period."

There is a major difference between being controlled to 2 bbl /min (5l/sec, 1100bbl/d)than having a wide open choke and only producing 2bbl/min.

GDY's ruptured casing was caused by H2S and extremely high tensile steel for their casing, which they needed for the high well bore pressures. Temperature changes would have would have added extra stresses and strains and would have been contributing causes. Beach by bring up the temp slowly will be trying to minimize theses stresses. I have not seen what the grade of the 7" casing PTR have used but bottom hole pressure (BHP) is approx 15000psi so it will also be of a high tensile strength, hopefully a little softer than GDY's and therefore less brittle and less affected by H2S.

As for multiple frac packs, there is no reason while several fracs cant be performed on the same well, i have done up to 3, but the shale wells in the USA have up to a dozen. One of the problems GDY had was getting packers for the correct temperature rating, and/or the willingness to pay for them.

Hopefully when Para #3 is drilled they will set the 9 5/8 just above the over pressured fractured formation that kicked on them on #2, allowing them to set 7" casing in the naturally fractured and over pressured zone which should have no flow issues due to permeability, and at 15000psi BHP, pressure is not a problem. We just need to make sure the two wells are communicating with each other, and we will be in business.

Here is hoping for the best and riding on the back of GDY's experience.
