Depending upon where you are and what type of wells you have, the drop is probably normal. If you have horizontal wells, they have a natural immediate decline which will be very steep for the first couple of years and then level out to low levels which can last for decades.
The second reason is a combo of the first and the drop in product prices over the last few months. More serious if you have gas wells.
The third reason may be nearby hydraulic fracturing jobs within a mile or so of your wells. Often the surrounding wells will be shut in during the jobs, so your production will drop and then hopefully pick back up.
Or combo of all three may be in play here.
