Both with getting the rig to mount it to the wall and with rigging up the air lines. We are waiting to use it after surface casing because we are waiting for Neil Shexneider to become available to help with instruction. The installation was easy and very smooth. There was good communication between all parties during the surface hole as this was the first well on the island that we were not using a diverter line. Communication was key to make sure all parties were paying attention toany potential high gas or gains in the pits. No issues resulted, but everyone did a good job. Difficulties experienced: After updating to the new Insite version (7.3.7), we ran into a problem with our IRIS data mapping and the data being WITS'd in from Canrig. All our WITS'd data had no folder to write to so we had to re-do our IRIS data mapping to accept the data files. Also, while setting up the upper gas trap, the adjusting handle broke. This has caused us to use the lower trap during the surface section. Recommendations: In the future, lubricating the adjusting handle for the trap might be a good idea so it doesn't sieze up. Innovations and/or cost savings: Surface Data Logging After Action Review Employee Name: Zach Beekman Date: 6-Aug-2012 Well: SI25-N2 Hole Section: Intermediate What went as, or better than, planned: Insite worked as it was supposed to with minimal to no problems. Difficulties experienced: About half way through the intermediate section, all internet connections were lost between the camp. We lost out feed to the geologist/co man computers and our WITS feed to Petrolink. Though this was of no control to us it was quite bothersome. A GCI rep was notified and sent to the island to fix communications. We also had our last full size sieve get broken by one of our sample catchers. The sample catchers were left with a 4" sieve originally used for drying samples and easy to use for cleaning. Recommendations: Need to have a few extra sieves on hand for when they break. Innovations and/or cost savings: Surface Data Logging After Action Review Employee Name: Emil Opitz Date: 18-Aug-2012 Well: SI25-N2 Hole Section: Production What went as, or better than, planned: Insite worked as it was supposed to with minimal to no problems. Difficulties experienced: Gas trap motor siezed up just prior to drilling production section. ECD's were not being recognized by INSITE, therefore we were unable to send to RIGWATCH for all drilling personnel to see real time. Recommendations: We had a backup gas trap motor on hand, and the rig electritian wired it up with the previous traps' premeasured cable. This made for an easy swap out. We learned that due to an INSITE update, all settings were deleted. INSITE updates should either incorporate custom settings, or warn users to backup/save custom settings/records. If neither of these two possibilites are feasible, than at least inform personnel that they will need to re-create all custom records. We learned this after drilling had commenced, and were unable to make any changes until the next run was started in INSITE - even if we had made changes, they do not take effect until a new run is started in INSITE. Starting a new run while drilling ahead in production section is not an option, so we were forced to wait until we could start a new run. This prevented us from WITSing real-time ECD data to all rig personnel and screens, as well as the Geo, Pusher, Company Man, and K&M rep in camp; all of whom depend on us relaying this data to them.
