re: start of the production rerating? Hi Dynofish. I did a quick web search for horizontal drilling and came up with a list of the most informative
Coiled tubing is the technique used and I doubt that the Stena Tay has this facility.
Horizontal drilling has applications in thin layers like Tevet Deep and also where there are a large number of adjacent pockets like Tiof.
I didn’t read everything but I looked at the pretty pictures in some of them. Regards Complex

Summary
Results from horizontal drilling have been highly varied. Successes on a large scale have been limited to the Austin Chalk Trend. And even within this sizable trend there are areas which have been unable to realize sufficient reserves to make horizontal wells profitable. It is apparent that not all fractured reservoirs benefit economically by the application of this technology. The two top states, North Dakota and Texas have produced over 285 MMBOE to date through horizontal wells, an important contribution to the US supply. Rapid return of investment due to high initial production rates, ability to implement economies of scale, and the realization of statistical averages with multiple well programs are the driving force behind continued use of the technique in much of the Chalk Trend.

A Crude Story in 5 parts written in 1999.
All 5 are parts interesting and amusing but the last part looks at horizontal drilling with diagrams. It also alludes to possible (future) conversion of gas to oil in situ. Maybe WPL should be looking at this.
