eni doing the homework

Seems to me ENI are taking the extra time and looking at all the data on this well they have before them and are taking a very close look at the core sample.

They know there is gas down there but want to know by studying the core sample if the formation will give it up, and at what rate it should flow at, even before they do a production test. If no gas was in place this well would have been plugged by now.

Its been discussed here and written down at geoscience
that when the heron gas bearing formation is shallower as it is here at blackwood, the gas flow better and is more productive.

here's a good interactive site.

core analysis

Laboratory study of a sample of a geologic formation, usually reservoir rock, taken during or after drilling a well. Economic and efficient oil and gas production is highly dependent on understanding key properties of reservoir rock, such as porosity, permeability, and wettability. Geoscientists have developed a variety of approaches, including log and core analysis techniques, to measure these properties. Core analysis is especially important in shale reservoirs because of the vertical and lateral heterogeneity of the rocks. Core analysis can include evaluation of rock properties and anisotropy; organic matter content, maturity, and type; fluid content; fluid sensitivity; and geomechanical properties. This information can be used to calibrate log and seismic measurements and to help in well and completion design, well placement, and other aspects of reservoir production.

core testing

Laboratory analyses performed on formation core samples as part of a stimulation-treatment design process. Tests such as the formation flow potential, fracture orientation and fluid compatibility tests are commonly run in preparation for stimulation treatments.
