Does anyone know what a "workover" rig is and what it is used for?

 

Thanks.

All I know is what Wikipedia has to say:

Are you aware of workovers being planned in the Liberty Field?  I have no idea if there is any potential for these wells to do better, or not...

Todd, workover rigs are smaller versions of drilling rigs that are used for various remedial well work.  One common task for Haynesville Shale wells is to install production tubing after a well has been producing 2-3 months and the water rate has declined.

Hi Les,

Okay, but the Anita Robinson was completed on 10/22/10, over 6 months ago.  Are we not a little late for installing production tubing?  Any other possibilities?  What I read about workover rigs indicates that they can be used in repairs; this well is a low producer, but latest production data seems in line with expectations given the IP (of course the well could have blown up in the last two months and I wouldn't know from sonris...).  It is, I suppose, also possible that Todd's comments about workover rigs are not specifically directed at this rig.

Robert, as you said Todd's comment did not identify a specific well for the workover rig or if one was actually in the field.  If will note I said that such rigs can be used for a whole range of tasks and simple offered the production tubing installation as one example.  Such tasks include both normal downhole activities as well as unforeseen repairs.  In absence of an AFE or a Sonris posting it is virtually impossible to determine the plans for a specific workover rig.

 

By the way, I checked and Sonris indicates the production tubing was installed during the initial completion which I found unusual in comparison to some other EnCana wells.

Anyone know about the "reworking" of this well? It was told to me that it is now producing 23000?????

BJ, production tubing was installed in the well in early April which is normally done after a well has been producing for a few months.  That could be 23,000 Mcf per month rather than day which would fit the well decline profile.
