Did CHK Counterfeit Marcellus Production Data?

I looked at CHK production data at Marcellus closer, and find more disturbing pattern which suggest that they may have pulled a DATA SCAM on the production of their Marcellus shale wells.


CHK had 321 Marcellus production in First half of 2012, By second half of 2012, 4 of the production wells were dropped and 94 new production wells were added.

The 4 wells dropped were:

015-20132, 015-20133, 015-21101, 015-21117

The 94 new wells added were:

007-20305,007-20344,015-20315,015-20375,015-20481,015-20495,015-20639,015-20665,

015-21240,015-21241,015-21243,015-21246,015-21290,015-21358,015-21370,015-21403,

113-20011,113-20019,015-21531,015-21535,015-21553,015-21555,015-21570,015-21571,
015-21572,015-21588,015-21591,015-21600,015-21604,015-21622,015-21654,015-21813,
015-21815,015-21827,015-21849,015-21850,015-21874,015-21924,015-21985,015-22003,
015-22020,015-22030,015-22072,015-22114,015-22115,015-22138,113-20004,113-20020,

131-20037,131-20064,131-20104,131-20231,131-20232,131-20234

There were 317 wells that produced in both first half and second half of 2012. The top producing 62 wells shows little production decline, the combined daily production of these group actually INCREASDE by 7.7% from H1 to H2 of 2012, going from 365.3 MMCF/day to 393.4 MMCF/day, or 5.892MMCF/day to 6.346 MMCF/day on a average per well basis.

The remaining 255 wells produced a combined 998.65 MMCF/day in H1-2012 and dropped to 737.25 MMCF/day, or dropped -26.2%. This percentage drop is the NORMAL and expected percentagedrop in half a year, for the group of existing shale wells. On per well basis production dropped from 3.92 to 2.89 MMCF/day.

I believe that CHK either unintentionally messed up the data and reported them wrong, or they intentionally pulled a DATA SCAM on the reported production data on some of the most productive wells.

The 62 wells with questionally high productions which do not seem to drop much, are:

131-20062 1476659 179 8249 131-20062 1653825 183 9037 9.55%


131-20062  is well number
1476659  is H1 2012 production in MCF (thousand cubic feet)
179         is days of production in H1 2012.
8249       is calculated average per day (=1476659/179)
131-20062 is well number again
1653825 is H2 2012 production in MCF (thousand cubic feet)

183         is days of production in H1 2012.
9037       is calculated average per day (=1476659/179)
9.55%    is percentage change of daily production, from H1 to H2.
