Marilyn the well is flowing 7 million a day on a 14/64 choke

Hi Skip,

 

This is RC's wife...I am trying to understand all of this lingo. What does "TD" mean? We have a well, I believe, being drilled horizontally from sec. 33 of 11, 12 into sec. 4 of 10, 12. On SONRIS it states

TD 12-22-10; SET 5" TO 17,648' W/ 885 SX. Can you help me understand what this means? since I'm the one who pays the bills, I'm anxious to know when we might start getting royalty checks!!

 

Thanks,

Lange

When a drilling report lists TD it is referring to the fact that the well bore has reached Total Depth and the rig has stopped drilling.  The Well Scout entry above gives the date the rig TD'ed.  Then 5" casing was run in the well bore and cemented with 885 sacks of concrete.  This is when work on a Haynesville horizontal well stops.  The rig leaves and there is nothing remaining except the Christmas Tree which is the assembly of piping and valves protruding above ground.  The well may remained this way for weeks or months waiting for a frac crew to begin completion operations.  The report notation during this time will often be WOC (Waiting On Completion).  The frac process is hard to miss for anyone in the area of the well pad because there is a lot of heavy truck traffic and around the clock operations for four or five days.  When the frac crew is finished the well may or may not be allowed to flow right away depending on pipeline connection or capacity.  Operators prefer to turn a well to sales ASAP after the frac I think.  When you see the report entry date for Turned To Sales mark it down as royalties will begin arriving three to four months thereafter.  Good Luck.

Skip,

 

Thank you so much. That is is very helpful! Just one more question...Do I understand correctly that if we have land in Sec. 4, 10-12 and they are drilling into that section from 33-11-12, we still receive royalties even though the drilling rig isn't actually on our property?

Yes, you understand correctly.  It is advantageous to drill a horizontal well from the section adjoining the one to be produced.  It has to do with getting the maximum length lateral in the unit section so as to leave no shale unproduced, if possible.  The ability to turn a tighter radius to change from vertical to horizontal has improved but obviously a 90 degree turn is impossible.  It can take some hundreds of feet to accomplish the turn.  To know when this situation is applicable to a particular well, check the first line of the SONRIS Lite Well Scout report.

In this example the surface location is given first as 256' From the South Line & 2311" From the East Line of Section 33.  The Proposed Bottom Hole Location (PBHL) where the lateral will end is 330' From the South Line & 2310' From the East Line in Section 4 - 10N-12W.

Hi Skip,

 

My section (36) is benefiting from the surface well in section 25. Do you think Petrohawk will eventually drill wells in section 36? If so,  would they be vertical or horizontal?

 

Thanks,

Marilyn

Section 36 is a Petrohawk Haynesville Drilling Unit so it is likely that they will drill it.  There is a fault running NE to SW  that clips the corner of 36 and cuts diagonally across Section 35 which is also a Petrohawk Unit.  There should be no problem to drill horizontal wells in 36.  35 looks to definitely have a problem which may require redrawing the unit.

You may want to review this discussion and use the link provided to see how units are redrawn to address faults.  There is a plat on the fourth page of the application.

Skip,

But Petrohawk is drilling Section 35.  Wel #242226 has plans to drill a full-length lateral running up the east side of the section.  Surface location is in 2-10-12.  Maybe the fault messes up the western part of the section?

The fault appears to go straight diagonally from the NE to the SW corner of S35.  A well with a reasonable lateral length could be drilled north from the SE corner of the section or south from the NW corner.  Any wells drilled closer to the middle of the section will have abbreviated lateral lengths or will have to penetrate the fault.  If the throw of the fault is slight, a driller might be able to steer the mud motor in such a way as to keep the well bore in the target interval.

An interesting way of obtaining a full-length lateral is found in 13-11-11.  Chesapeake plans to turn a greater-than-90-degree angle on the well bore.  You can see it if you pull up the permit to drill on sonris.

Thanks for the information, Buckmaster.  Is this an average, good or very good well?
