3-D seismic shows a seismic thickening & “pull down” of a 2nd peak in the upper Sligo section and in the prospect areapossibly indicating Ф development & HCs. This seismic anomaly is not seen in the other wells in the area.

prospect attributes
Prospect Attributes
  • Primary objective is the Sligo Fm (L. Cretaceous)
  • The prospect also has a large Edwards Fm anomaly
  • The 3-D shoot: 48 fold @ 18,000 ft.
  • Prospect enhanced by High Resolution Color Inversion
  • “Flat Spot” seismic anomaly unique to La Jolla & Wheeler #1
  • Anticipated accumulation size: 30 Bcf/well
  • Upside potential: Multiple Wells 300 - 400 BCF
  • Estimated initial production rate: 10 – 15 MMCFD
  • Overpressured, minor amounts of H2S (100ppm)
  • 8% CO2 anticpated

Across the perforated interval & within the anhydrite layered zone, Sw has a direct relationship to the porosity (Ф), such that in each flow unit, as Ф increases, Sw decreases.

This occurs where Sw is a function of pore type, and well above any gas-water interface. Ths is confirmed by a H20 free completion & several months of H20 free production.

Below the anhydrite layered zone, the lowest Sw occurs @16,700 ft in the highest Ф flow unit in the entire well. This is still in the free gas column – a separate accumulation below the anhydrite rich facies.

The base of the gas column may occur @ 16,730 ft where Ф remains in the 6-8% range but Sw registers 89%. This appears to be the top of the transition zone where both gas & H20 are mobile.

comments re h 2 s co 2 h 2 o
Comments Re. H2S, CO2 & H2O
  • Corrosive gas quantities are quite low, ranging from 40-120 ppm
  • When combined w/ water, temperature & pressure considerations, this becomes more than a nuisance.
  • Extreme care should be taken to use optimum quality tubulars.
  • Had this been done @ the Wheeler #1, the casing likely would not have collapsed.
drilling and completion considerations
Drilling and Completion Considerations
  • The key to a successful Sligo test is to hit the target within a 150 ft. radius of the defined site coordinates.
  • This will require real time direction information and LWD data.
  • In conjunction with an effective acid frac, this will make all the difference between a good or a marginal well.
  • Casing & Tubing must be high end anti-corrosive
  • Overpressure & H2S require key decisions related to drilling safety , casing & intermediate string placement.
