Hi.
There is not a lot of info, but I'll give 'er a rattle:
It looks like at 3 pm Wednesday, the well began loading with fluid, as your gas volume is decreasing. This may have been a gas locking situation of the insert. At about 6pm, the well unloaded and flumped and flailed for a while, until it gas locked again. It looks like your jack may have been down until about 0100 Thursday morning, when it began flumping again.
Possibly you are seeing gas locking as a result of tail joints in your well. I would suggest having sumping your pump deeper and hanging a pump joint below your pump, so that the strainer nipple is below the tubing string. This will serve to reduce your gas locking.
Hope this helps but caveat emptor....
