Tuscaloosa Marine Shale Strategies

Early in the TMS play, some diverse strategies can already be determined:

Location:
---Devon: Updip, Middip; mostly in LA
---Encana: Updip, some Middip; LA and MS
---Indigo Minerals: aggregate large block around existing minerals in LA
---Goodrich: scattered "islands" across LA and MS
---EOG: stealth mode; mostly Updip, some Middip
Drilling:
---Devon: laterals oriented parallel to dip; lengths: 4840'-6540'
---Encana: laterals oriented oblique to dip (~15 degrees); lengths: 6738'-6941'
---Indigo Minerals: laterals oriented oblique to dip (~5 degrees); length: 4250'
---Goodrich: "2nd mouse gets the cheese"?
---EOG: "2nd mouse gets the cheese"?
Evaluation:
---Devon: drill vertical "science" well 1st and obtain conventional core
---Encana: re-enter existing horizontal wellbore and complete; obtain conventional core in the first new horizontal drill
---Indigo Minerals: drill vertical "science" well 1st and obtain conventional core
Unit Size:
---Devon: 720-880 acres (square, rectangular)
---Encana: 1030-1074 acres (rectangular)
