Gas Control looks at the 3 receipt/delivery points we have with Viking an= d net everything out at Pierze. Dependant on pressures on both sides at the= Pierze point determines whether we have to run. We try to batch if we can = on our side if it fits our operation. We may not always be able to do it if= it does not work for them. In some ways there maybe a trade off between ru= nning Alex or Pierze. Now that we are getting into winter months we are g= oing to want to keep our pressure up higher for Benson, There may have bee= n times that we may have lost a opportunity to not run Pierze, but sometime= it may look like a opportunity but all the pieces may not fit for everyone= . Gas Control will continue to try shut Pierze down when they can and with = the cooler temperatures Viking may run with higher pressure which would all= ow us to free flow more often. Is there a economic difference between runni= ng Pierze vs. Alex? We are always open for suggestion or ideas so if you se= e something operational that would make for a better operation please give = us a call.

When we run the Pierz Compressor, it is about $300 a day in electric bills.= That in and of itself, is not a big deal if there was no other way to ope= rate the system. It appears to us if the pressures on Viking's system stay= at a good level, we can free-flow nearly twice as much gas into our system= through valving and save the cost of running horsepower. There were times= over the past months where we operated like that for extended periods and = we realized a huge savings in O&M $$. It did not seem to be a big deal to = keep the unit idle.=20 We will not claim to understand all the "ins and outs" of the system. We s= ee our little part of the world, and it appears to us at least on the surfa= ce, that there may be a much more economical and more efficient way to run = one of our facilities. We ask you to take some time and provide us with so= me of Houston's background thinking on the operation of the Pierz Compresso= r Station. Thanks,=20 Tom
