“Equipment: the test section (coal formation) is isolated from the rest of the wellbore using inflatable packers which from pressure seals. The length of the test sections are selected based on drill core inspection and geophysical logging. The straddle length of the packer system (distance between the two packers) is made up accordingly and the entire packer system including downhole gauges and a shut-in tool is assembled. The packer system is then run on rods into the open borehole or on a wireline inside rods down to the test section. In the latter case, the rods will be placed shortly above the selected test section and the packers isolating the test section will be placed below the lower end of the rod string so injected water cannot flow into the annulus but to the isolated section only. Testing procedure: The packer system is run down to the test section and the packers are inflated using water, nitrogen or compressed air to seal the test section off. In an IFO test, water is pumped into the rod string at the surface and therefore injected into the test section downhole, usually at an approximately constant rate. The injection pressure is monitored at the surface. It should not exceed a predefined limit which is calculated based on the depth of the test section in order to avoid hydraulic fracturing. The injection rate is controlled in order to maintain the injection pressure below the estimated fracturing pressure. After the period of water injection, the well is shut-in for an extended period, usually several times longer than the injection period. The pressure in the packed-off test section is measured throughout the test; both during the injection period and during the shut-in period. Downhole pressure data after shut-in represents the pressure decline and is used to analyze the fall-off period. Further, the static formation pressure can be estimated from the downhole pressure data at the en of the fall-off period. Permeability measurement: The permeability cannot be measured directly but is analyzed from pressure data and flowrate data. Permeability cannot be calculated if no flow is measured. However, in cases when it is not possible to establish an injection flow rate, this is an indication of very low coal seam permeability. [This last sentence is not agreed to by Eden’s expert]”
“As a result of [Omni’s] failure to exercise any reasonable skill and care…during the February 2008 testing and/or incorrect analysis and reporting of the permeability testing at the Llangeinor No. 1 well the Defendant was unable to sell its share in the South Wales Resource to Centrica and/or had to put the negotiations for the same into abeyance. It was (or would have been) impossible to negotiate a proper price for the sale of the [Eden’s] share without any valid results for the permeability testing. [Eden] thereby lost the opportunity to effect a sale of 90% of its share of the South Wales Resource at a price between£18 million and£29.7 million ”
“21. The failure to obtain any conclusive results even as a result of the re-testing meant that the value of the South Wales Resource remained uncertain and was therefore a less attractive investment for any potential investors such as Centrica. Further, the delay in carrying out the re-testing also delayed any potential sale until the second half of 2008. By September 2008, the economic situation had worsened considerably and the climate for investment had significantly deteriorated with the result that conditions for investment in the South Wales Resource and the sale of part of the [Eden’s] share in the South Wales Resource had also deteriorated significantly. 22. By reason of the matters aforesaid, [Eden] lost the chance to sell its interest in the South Wales Resource on the basis that its 50% interest was worth between£20 million and£33 million …and was forced instead to sell 90% of its stake in the South Wales Resource at a reduced value. The final sale price to Centrica for 90% of [Eden’s] interest in the South Wales Resource was£2.5 million . 23. The sale of 90% of [Eden’s] interest in the South Wales Resource on the basis that it had a value of between£20 million and£33 million would have provided a price between£18 million and£29.7 million . The actual sale price was£2.5 million . Therefore, by reason of [Omni’s] negligence and/or breaches of contract, [Eden] has suffered loss and damage of between£27.2 million and£15.5 million .”
“…the Claimant deliberately misrepresented the position to Mr Oliver Taylor (acting for and on the half of [Eden]) by informing him: 14A 9.1 only that ‘permeability would probably be low’; and 14A.9.2 that [Omni] (in the person of Jim Obluda) was ‘happy’ with the way the packers operated’”
“14B. By deliberately failing to inform [Eden] of the true position (by failing to inform [Eden] of any of the facts and matters pleaded in paragraph 14A.8 above) and/or by deliberately misrepresenting the position to Mr Taylor as alleged in paragraph 14A.9 above, [Omni] intended that [Eden] would not abort the tests and instead allow them to continue. 14C. By failing to reveal the true position to Eden, [Omni] falsely represented to [Eden] and/or falsely induced [Eden] to believe that the packers were fit for purpose and/or that further testing was worth carrying out and/or that meaningful results could be obtained. [Omni] knew (or ought to have known) that if the true position had been revealed to [Eden], [Eden] would have aborted the testing with the Priority Packers. 14D. In reliance upon [Omni’s] false representation as aforesaid and/or induced by its mistaken belief as aforesaid, [Eden] allowed the Llangeinor testing to continue through February and March 2008. 14E. If [Omni] had revealed the true position to [Eden], [Eden] would have immediately directed [Omni] to: 14E.1 stop testing with the Priority Packers; 14E.2 obtain packers capable of operating up to as high a pressure ia that recommended by Mr Mavor or Mr Wood; 14E.3 move the testing to Pencoed until the new packers for Llangeinor become [sic] available; and 14E.4 retested at Llangeinor when the new packers arrived. 14F. the deliberate nondisclosure by [Omni] continued from31 January 2008 until18 March 2008 , by which time the testing at Llangeinor was completed…” 14E.1 stop testing with the Priority Packers; 14E.2 obtain packers capable of operating up to as high a pressure ia that recommended by Mr Mavor or Mr Wood; 14E.3 move the testing to Pencoed until the new packers for Llangeinor become [sic] available; and 14E.4 retested at Llangeinor when the new packers arrived. 14F. the deliberate nondisclosure by [Omni] continued from31 January 2008 until18 March 2008 , by which time the testing at Llangeinor was completed…”
