Without knowing the specific well you are referring to it is unlikely you will get any specific answers.
The database does not recognize that API number. Do you have a Serial Number or well name with section-township-range?
That well is HA RA SUVV; PLD ETAL 21-12-12 H #1; SN241272.
Joe, there are three potential reasons among others.
1) Chesapeake is performing either well work or work on associated facilities requiring shut-in.
2) The surface flowing pressure has declined to the pressure of the high pressure gathering system and Chesapeake has not yet switched the well to a lower pressure system.
3) Chesapeake has elected to curtail production in response to the current oversupply situation.
