TD announced on 24th April at 2370m. Y zone intersected the previous day probably at 2270-2300m.
TVD? The depth of the lateral and the corresponding fracture stages would be conducted in the Y
zone at 2300m. That's the depth where the build up in pressure is from. That's how I read it anyway.

Most EFS wells are in the range of 1500m - 3500m TVD. Dry gas wells are at the lower end of
the range whilst wet wells at the higher end. So if we are at 2300m then that's a fair depth for
fairly good pressure if the well is wet. A lot of 1000-1500m laterals with up to 10 frac stages or
or 24 fractures v 77H at 350m and 8 fractures. Wells in the sweet oil spots can generate IP's of
800-1300 boepd, 80% condensate, 20% dry gas. So a good IP for 77H on a crude average of
this {and assuming it's a high quality basin similar to the EFS} would be around the the 350
bopd mark plus any dry gas. It is after all a concept well and lessons will be learnt from this
one. Maybe notably the frac fluids used if in fact this well is predominately wet.

Wet wells require higher fracture conductivity as a result of higher viscosity fluids. The main
difference between dry and wet wells is the design of the hydraulic fracture treatment. For
the liquid rich area a hybrid system is usually pumped with lower fluid volumes and pump
rates and higher proppant concentrations. 77H comprised of 4100 bls frac fluid, 20 000
barrels water & 136 tonnes of proppant. I'm just assuming here that because "the light
oil recovered exceeded our expectations" the frac design was based more on a dry well
than a wet one.

The point being I suppose is that if 77H is predominately wet {which would be a great result}
then better techniques as those above plus longer laterals and more fracs could only bode
well for future planning and development of further wells.

Pregnant?? 4 years in incubation, let's hope for a monster.
