BYE (ASX) Ann: Appendix 2A (Entitlement Issue)

Originally posted by OldGeo: ↑

Hi arthuros,
The flow rate of 2,300 bopd from the SM58-011 discovery well is what in the industry is referred to as tubing constrained. Because the SM58-011 well is limited to a production tubing size with a 2-7/8" internal diameter, the flow rate is constrained to no higher than 2,300 bopd at the known the reservoir pressure. i.e. the well physically cannot produce at a higher rate than 2,300 bopd even if it was capable of flowing at a higher rate, because the physics of the 2-7/8" tubing simply will not allow it to. In my view, a 2,300bopd rate from a single well in the shallow waters of the GoM is pretty damn good.

That said, in the development well planning process for the SM58 G2 development well for example, BYE's drilling and production engineers are likely looking at a well design that may enable the running of larger production tubing i.e. tubing greater than 2-7/8" internal diameter which would allow flow rates higher than 2,300bopd. We'll see what they come up with next year.

That said, oil flow rate depends on many factors - the diameter of the tubing (2-7/8" in SM58-011) is only one of them. Oil flow rate also depends on things like reservoir pressure (what is pushing the flow through the tubing), the kind of fluid flow happening in the pipe (laminar flow versus turbulent flow), the friction caused by the walls of the tubing, the viscosity of the fluid flowing through the tubing. Sorry for all the geeky science stuff.

By way of analogy, the best oil producing well in BYE's SM71 field, the F003 well had a peak rate of around 2,300 bopd.

Hope this helps.

Kind regards OldGeo

Hi Oldgeo,

thanks for the reply.
It all makes sense what you are saying. Current well max production is constrained @2300 BPD due to the diameter of the tubing.

I was hoping that if they are happy with the pressure on the upper O sands they may decide to re-drill the lower O sands, maybe doubling the potential BPD. (if cost effective, given that the drilling companies catastrophic error is responsible for the smaller diameter tubing being used).

Are the upper and lower O sands considered 1 or 2 wells.

Cheers

Arthuros
