Slide 1

Rock Wash Casing Profile Texas Panhandle (District 10) Western Oklahoma OKC Granite Wash Conference – March 6, 2008

Slide 2

Surface Casing Regulations District 10 Office is situated in Pampa, Texas Railroad Commission - District 10 – Jan 1996 "Zone of Critical Cement" Bottom 20% of packaging string with at least 300 ft At different stage establishing instrument – quick 300 ft above device Cement Blend Requirements Cement in the "Zone Of Critical Cement" must meet or potentially surpass a compressive quality or 500 psi before penetrate out and 1,200 psi in 72 hrs Cement over the "Zone of Critical Cement" may contain extenders, however the bond must have a base compressive quality of 350 psi in 24 hrs after arrangement. Additionally the slurry weight can't be under 12.7 #/lady with an API free water of close to 6 mls for every 250 mls of concrete as indicated by API RP 10R test methodology

Slide 3

Surface Casing Regulations District 10 Office is situated in Pampa, Texas Railroad Commission - District 10 – Jan 1996 Centralizers Surface packaging string should be brought together at the packaging shoe If a multi-organize cementer is utilized, above and beneath the instrument Plus 100 ft underneath the base of the usable quality water, a centralizer might be set each fourth joint to the ground surface or to the base of the basement "Administrators must inform the District Office in the event that the concrete does not flow to the ground surface" "A temperature overview or bond log well be required if the concrete is not circulated to the ground surface"

Slide 4

Surface Casing Regulations Texas Railroad Commission - District 10 – Nov 2005 Maximum packaging profundity won't surpass 3500 ft Surface packaging should be set before boring into known shallow oil and gas developments. "Zone of Critical Cement" Bottom 20% of packaging string with at least 300 ft From numerous stage establishing device to the surface Cement Blend Requirements Cement in the "Zone Of Critical Cement" must meet as well as surpass a compressive quality or 500 psi before bore out and 1,200 psi in 72 hrs Cement over the "Zone of Critical Cement" may contain extenders, however the concrete must have a base compressive quality of 350 psi in 24 hrs after position. Additionally the slurry weight can't be under 12.7 #/lady with an API free water of close to 6 mls for each 250 mls of concrete as indicated by API RP 10R test methodology

Slide 5

Surface Casing Regulations Texas Railroad Commission - District 10 – Nov 2005 Excess Cement "Administrators are urged to utilize 150% abundance is calibration of surface gap is not decided" Surface packaging beneath 2500 ft will require a different stage solidifying instrument no less than 50 ft underneath consumable water, bond must be flowed to the surface Centralizers Centralize the shoe Centralize above and underneath the various stage establishing neckline Plus 100 ft underneath the base of the usable quality water, a centralizer might be put each fourth joint to inside 140 ft of the ground surface "Administrators must advise the District Office in the occasion that the concrete does not circle to the ground surface" "A temperature study or bond log well be required if the bond is not circulated to the ground surface"

Slide 6

Texas Panhandle Vertical Well Intermediate Casing 9 5/8" packaging set over the Brown Dolomite Cemented to the surface, single stage Production String Casing hurried to aggregate profundity Cemented over the gainful zones of intrigue 2 organize system to place bond over the Brown Dolomite interim Optional single stage solidifying strategy utilizing ultra light concrete slurry to place concrete from the aggregate depth to over the Brown Dolomite interim Productive Interval

Slide 7

Texas Panhandle Horizontal Well Intermediate Casing 9 5/8" packaging set in the Penn Shale, underneath the Brown Dolomite; Cemented to the surface, single or two phase Kick Off Point – Below the Cleveland or more the Oswego Production String - Without the 7" packaging string Horizontal area solidified to put the highest point of the concrete +/ - 500 ft over the Kick Off Point Cement set over the Brown Dolomite with a solitary stage ultra-light concrete slurry or two phase solidifying process Productive Interval

Slide 8

Texas Panhandle Horizontal Well Intermediate Casing 9 5/8" packaging set in the Penn Shale, beneath the Brown Dolomite; Cemented to the surface, single or two phase Kick Off Point – Below the Cleveland or more the Oswego Optional 7" packaging string set through the bend; cemented to +/ - 500 ft over the Kick Off Point Production String With the 7" packaging string Single stage establishing procedure to put the top of concrete +/ - 500 ft over the Kick Off Point Productive Interval

Slide 9

Surface Casing Regulations Oklahoma Corporation Commission (165:10-3-4c) Minimum Surface Pipe Depth "surface packaging should be run and established from bottom to beat with a base setting depthe which is more prominent of: -Ninety (90) feet beneath the surface or -Fifty (50) feet beneath the base of treatable water" Maximum Surface Pipe Depth "Might not be more than 250 feet beneath the base of treatable water" Minimum Cement Setup Time "The bond behind the surface packaging should set at least eight (8) hours before further penetrating."

Slide 10

Western Oklahoma Vertical Well Intermediate Casing Set to cover low repository weight or lost course intervals. Solidified to cover the interims of concern. Creation String or Production Liner Casing raced to aggregate profundity Cemented with a "light weight" concrete slurry with the TOC inside the transitional packaging string. Creation liners have a base 300 ft cover and minimum 200 ft of top bond over the liner holder. Gainful Interval
