I would also like to find out the reason for the change in lateral direction. Encana is the majority lease holder in my section and have told me that they will drill a well in the 2nd quarter of 2010.

I am located in Sec. 13 and know most, if not all, of the land/mineral owners in Sec. 14 where an east to west lateral is proposed. I don't think that the reason for the e/w lateral is due to lack of a surface location, road, etc. Sec. 14 is very rural with 4 existing Glen Rose well sites, all with roads, pipelines and water supply. Encana purchased all of the pre-existing wells, pipelines and leases already in that section and additional leases in Sec. 13.

It must be for geological reasons.

Same situation with their BSTMA well in s17 14/11. No problem with location at all. They had initially inquired about locating the pad in the SE corner of the section but ended up where they're at.

In the STR call yesterday they touched on the spacing issue but didn't get specific. They said due to the "tight spacing in the Haynesville" they were trying different fracing techniques. Just going by the rule that your perfs can't be closer than 300' to the section line, If a frac has a 600' radius you could get 8 wells in parallel per section. Disclaimer - I'm clueless about this stuff so...

Bacon,

If you get a chance to read it, I think that Encana's permit for Sec. 25 15n 14w calls for the lateral to be drilled diagonally in the section. I may have read it wrong though.

In some cases, can the laterals be drilled across one another like this: " X " or
over or under one another? I just thought that in most cases, the laterals would be something like this:
" l l l l l l l l "

A diagonal lateral can be 40% longer than a "NS or EW" lateral. It probably makes it more difficult to drill wells later to efficiently drain the section because you can't space the other laterals parallel to it.

It seems that you get more money out of your first well, but suffer some consequences later. I don't know if this is a "legitimate" financial decision from getting the money now, or simple short sightedness.

By the way, is there a good term for a "non-diagonal" lateral?

Caliente, 660' spacing between wells equates to 80 acre spacing (660' * 5280' / 43560 sf per acre).

Does anyone have a gut feel for how much production varies going with vs. against the grain? Does it affect total production, or just the rate? i.e. do you get the same amount of gas out, but you simply get it out over a longer period of time?
