I believe the ongoing costs of production for each well is around $1-2 per barrel and I'm guessing thats based on the 25bopd average they project for each well.
So I wouldn't worry about costs of running the wells as its really a pittance.

At this point in time they are getting to be cashflow Neutral, which means they can spend more money developing wells, so instead of getting the 2 per month target they can start doing 3 or 4+.

I would suggest that as a reason for increased development costs Gull. 4 wells per month would be fantastic.
