Smackover Sand Deposit

Encana has permitted to this formation in north Desoto. I have heard that Petrohawk has 2 test wells to the Smackover in south Caddo. Is this a 3rd gas formation or part of Bossier and or Haynesville?

Forest has one permitted for Sabine Parish also.

The Smackover formation is geologically older than the overlying Haynesville/Bossier Shale zones, and is not recognized as a "part" of the shale zones. In fact, the Haynesville Shale Zone is geologically defined by the Commissioner to include the shale formations found below the Cotton Valley zone and above the Smackover zone. If production were to be established in the Smackover, additional units would need to be established for Smackover production.

KCM, I believe the permits just say Smackover and do not specify sandstone, limestone or shale but if you list the wells I could take a closer look. It is possible the Smackover designation is in error and the wells are actually Haynesville Shale wells.

Ken's Forest well in Sabine Parish is a little more of a mystery because of location and it is also a vertical test.

In May, Encana permitted 3 non unitized wells for Smackover for Sec. 26/15n14w Desoto (Senator Davis' land). I will get info on new wells permitted by Petrohawk to Smackover. They are off Wallace Lake Rd. in south Caddo. I initially thought that the Encana wells were a typo, but after talking with several seismic crews over the last year in north Desoto, ALL say they are looking for the Smackover. Then these wells show up as permitted to Smackover. Coincidence? Maybe

Hi Les

I have always wondered about this formation. What is the depth of this formation in North Louisiana? It has been drilled in the state line area of Ark. and La for along time. I have property in the delta area and in bienville parish. This is all very interesting to me. Just wondering about the depths in both spots. Do you think it is oil or gas that they are looking for or both?

Marc, as stated above the Smackover Formation would be located immediately below the Haynesville Formation and above the Norphlet Formation & Louann Salt layer.

Thanks for the geologic picture. Not a geologist but new to the game Les. I am trying to lear as much as possible. From what I remember the Smackover was a formation that produced oil. Do you think it has an opportunity to produce gas?

Marc, the Smackover can be oil productive or natural gas productive dependent upon the location.

Would drilling a Smackover well be more expensive or less expensive than the Haynesville ?

A horizontal Haynesville shale well would cost 3 to 4 times what a Smackover vertically drilled well would. All Smackover wells I am familiar with are drilled vertically. But, coming soon will be some horizontal Smackover wells, I predict.
Current cost to drill and complete Smackover vertical well is about $1.7 mil.

A vertical Haynesville SAND well would be slightly less expensive than Smack. well because it will be shallower.

Most Smackover wells in the area produce gas and condensate or gas an oil. Without the gas to lift the oil we would see few Smackover wells as it would be too costly to pump the oil. But, lots of really old Smackover wells do eventually get equipped with pumping units.
or plunger lifts.

Wells are classified as either oil or gas wells depending upon the ratio of oil and gas in a given well.

KCM, I do recall our previous discussion regarding the following three wells. My only concern is the permitted depths are very similar to Haynesville Shale wells.

EnCana, Jackson Davis 35 #H3 Well, Serial #241286, S26(35)-T15N-R14W, Lower Smk
EnCana, Jackson Davis 35 #H4 Well, Serial #241287, S26(35)-T15N-R14W, Middle Smk
EnCana, Jackson Davis 35 #H5 Well, Serial #241288, S26(35)-T15N-R14W, Upper Smk
