    Career Advice

    Dan, As an engineer, the two types of companies in the upstream oil industry that you'll work for are operators and service companies. There are other jobs, but 95% of the time it will be one of these. Operators usually explore, drill, and produce. They reap the rewards of the production...

    Refrac Discussion (specifically for the Bakken, but open to any/all plays)

    I'm looking for opinions on the different methods to refrac underperforming wells in the Bakken. Each well must be considered individually so I'll give you some details on the current well I'm looking at. Drilled and completed in '08 Landed in the Three Forks In some of the best acreage in...

    Wellhead Vibration Monitoring

    Thank you! Your post was very helpful. I've contacted PCB and I think the way to go is their wireless monitoring device. It's a little pricey, but seems perfect for the application I need. If I did want to go with the non-wireless monitoring system you linked, would you happen to know a...

    Wellhead Vibration Monitoring

    I'm looking for a system to monitor, and record, vibration data at the wellhead. We're in the process of finishing off a large multi-pad well that has had quite a few changes to its drilling schedule. Recently, there's been some concern with flanges coming undone or valves being comprised when...

    Problems getting well to flow after extended shut in

    EDIT: "All politics aside, I'm looking for cases in which non-compartmentalized, proven reservoirs have been damaged during a long shut in." I'll choose my words more carefully. I'm looking for any case in which people had trouble REGAINING FLOW after a long shut in like this. Not necessarily...

    Problems getting well to flow after extended shut in

    Sorry bout that, should've been a little more clear. The wells were drilled, cased, and all tested dry clean gas. They were then shut in for a few months while waiting on pipeline to be built. The production data is where it gets tricky. The only data available is the total mcf produced each...

    Problems getting well to flow after extended shut in

    I'm looking for any examples of people having trouble getting a well to flow after an extended shut in (a couple of months). I'd like to read any texts that show what caused the decreased flow, and any solutions they found to remedy this problem. Any insight would also be appreciated. Thanks!

    Cum. production doesn't equal the initially tested production rate.

    The production data is the problem. It almost looks like they produced about one day out of the month, and missed huge pay zones for no apparent reason. In my opinion, they did not perf the right zones, but I can't for the life of me figure out why. When looking at the logs, the zone they...

    Cum. production doesn't equal the initially tested production rate.

    I've got a special problem. Here's the scenario: * Many wells were completed in three separate fields. This was some 40 or 50 years ago. * The three fields are within an area of about four townships * Geological work shows the fields to be nearly identical. Testing for each field shows large...
