I am unaware of any horizontal Hosston wells in LA.  Numerous operators have leasehold proven for Hosston reserves including some that drill horizontal wells in other formations, CV or HA.  There is no benefit to drilling and completing a horizontal well in a formation that is more economically produced by vertical drilling.  Horizontal wells are almost exclusively employed where there is insufficient permeability for hydrocarbons to flow to a well bore in economic quantities.

Skip---How many acres can you recover and drain gas from on vertical Hosston (TP) well? I've seen spacing of 40 and 80 acres field rules for TP in East Texas

There is no standard as far as I know.  Each location and specific reservoir can vary in physical properties.  You can look up the well spacing for that particular formation in both states and get an approximate idea of drainage area.

Non-contiguous, linticular SANDS.

not aware of any horizontal Travis Peak..In Nacogdoches in Appleby Area EOG looks to have drilled on  down to 40 acres or so on wells  in 640 acre --as decribed below lenticular and not homogenous over large area so would NOT be candidate for Horizontal

Hey, this question brought up another one...what if anything happens to an established oil producing field, like Hosston, La and Rodessa areas [old time]? does frac method damage water resources like creeks, water wells and the like?

The wells in early oil fields are not fraced.  Back then or today.  That's because the formations they produce from do not require fracing.  And fracing has no relationship to "damage" in creeks, water wells or any other surface or near surface formations.

Skip-- does most of oil formation require some thing like acid treatment after perf done?

Some, not all.  Depends on the petrophysical characteristics of the specific formation.

Skip-- horizontal drilling in some formation for oil without hydraulic  fracing works in a "naturally fractured" formation like the Austin Chalk is that correct it's produced from "open hole" without liner?
