Thanks for posting, Les.

The H indicates it will be a horizontal.  Permit says 18400 feet, so I think the lateral will be quite long.  A lot of fracking will be done.

Measured Depth minus True Vertical Depth = approximate lateral length.

I would like to know the physical address for this operation. Thanks

Thanks so much.....I


06/03/2019 05 12885 DROVE 16" TO 115' W/ 86' PENETRATION; SPUD 5/28/19; DRLD; RAN 9 5/8" CSG TO 3090' W/ 1079 SXS CMT; NU & TSTD BOP'S 5/30/19 (ANNULAR: T-90, 13 5/8", CAMERON, 5000; RAMS: TYPE U, 5", CAMERON, 10000); TSTD CSG; DRLD CMT & FLOAT EQUIPMENT & PERFORMED FIT; DRLD VERTICAL HOLE F/ 3090' TO 12885';

Thanks for posting this. In looking at the dates, it appears that EOG got this well drilled to 12,885' from surface casing point (3090') in about 4 days.

9795' of drilling over that period - doable but ultra fast.

This is the benefit of not having to stop in this area to set intermediate casing. And obviously no lost circulation issues or drilling problems.

Underscores the differences in the subsurface section and issues across a play area.

Wow, looking at EOG's 6/10/19 & 6/17/19 reports for the Ironwood well, they have already drilled their lateral to TD at 18,230' (spudded 5/28 and drove initial casing by 6/3).  Seems COP's McKowen well took over twice that amount of time.  Their Irwin well seemed to get to a similar point in about 7-weeks.  Is this just the nature of the game where you don't know what to expect from one drill to the next or is EOG more efficient?  

Lots of factors involved in these drilling times including the expertise of the companies in question, the pressure situations and hole integrity (plus lack of pressure kicks and faulting) in the area being drilled and the need to run additional strings of casing.

Not all areas are the same when it comes to drilling efficiency capabilities..

thanks, well put RM.

Response to Bob as to in the impact of "different environments". The depth issue to be considering is not TMD (total measured depth) but should be TVD (total vertical depth). Once one crosses into a higher pressure regime (and in this case, a much higher pressure regime), drilling becomes much more difficult for many reasons - initially to run additional casing for wellbore protection. This takes a lot of time. Then drilling in higher pressure environments with higher (and more expensive and exotic drilling fluids) adds time to the drilling equation.

This situation is then even more complicated if natural fracturing  or faults (or both) are encountered while drilling. Imagine what happens if you have heavy drilling mud in the hole to handle and control high formation pressures and then hit a "void" associated with a natural fracture or fault that starts to suck up all your drilling fluid. Which can then create a blow out or lost well control situation. 

All this equates to more drilling time and lots more $$$ being spent.

It is not unusual for members to occasionally feel that industry members are negative in their remarks regarding an emerging play.  For those of us who have been around these now eleven years we know from many discussions that Jay is not only highly qualified to comment on plays and the complexity of drilling and completion challenges, he works in the industry and has access to data and reports not commonly found in the public record.  He has been around the block many times in his career and often helps to put the risks associated with operations in prospective for those of us who are less experienced.  Jay is one of us and a land/mineral owner in the Haynesville Shale.  His input is highly valued and appreciated by the members.
