Two laterals?

http://sonlite.dnr.state.la.us/sundown/cart_prod/cart_con_wellinfo2...

Any idea what's going on here?

Two laterals.

Starts in one section and drains another. I know this is done sometimes, but there's no obvious obstructions in the section it's draining.

There's no unit indicated for the section it's draining.

Looks Like a mapping error. The permit was amended for a new surface location (in sec 17), but the original bottom hole was not deleted from the GIS system.

Mac, the well has only one lateral. Please see the attached. By the way, wells are typically surfaced in adjacent sections to maximize perrforated lateral length rather than due to obstructions.

this well was originally plated witha different location for surface and BH. They changed the surface, added a new PBHL but did not delete the old PBHL. So in the GIS maps it shows as one surface with two laterals.

I'm Kinda PO'ed. They messsed up my map.

Les,

Does the fact that the lateral is located 390' from the west line indicate that HK is allowing for possibly 60 acre spacing (12 wells/section)?

WR, it could indicate 7 wells/section or ~ 91 acre spacing.

Thanks. The two laterals seemed weird, especially the short one straddling the section line. I figured it was an error of some kind, but you never know when they're doing something weird.

Why does starting in an adjacent section give you a longer lateral? Is it that you can make the curve at the bottom and get horizontal closer to the edge because you have a minimum radius for the bend? What kind of radius do you tend to use on the curve?

Is the perforation point the point at which you start perforating the casing?

Starting in the adjacent section could have many benifits, friendlier landowner or possible superpad for example. But yes you are coorect, they can turn pretty quick, but they will loose a few hundre feet hort. in the turn. also, the perferatonpoints are rtequired to be a minimum distance from the unit line, this senerio allows them to perferate as close as allowed.

you are correct, Perferations are where the cassing has holes shot into it into the formation. The Perferation point is where they will begin. If you look closly at the completion reports you c an see the intervals perferated.

Mac, the perforations can be no closer than 330 ft to the section line. So the idea would be to have the bend completed by that point. Typically this means a maximum perforrated lateral length of ~ 4620 ft.

What minimum radius do they tend to use on the bend?
