Dear all

I am trying to model horizantal well in Prosper using following prameters,

K= 0.3 mD
Pr= 4000 psi
Gas Gr= 0.65 (Fluid=gas)
Tr=200 deg F

Reservoir Dimenssions:
Length: 6 sq.km
Width: 1 Km
height=5m

Assumptions:
Lateral length (heel to toe): 600 m
No water, no condensate

Prosper calculates around 2 MMSCFD of gas rate,

History: vertical well on on the same anticline has produced 0.5 MMSCFD at h=5m & k=0.3 mD.

Issue: If we look at the history and do a simple calculation for rate in horizantal well the rate should be around 30 MMSCFD or near to it, not 1/2 MMSCFD that propser calculates. See table

h, m rate, MMSCFD
Vertical Well 10 0.5
MMSCFD/m 1 0.05
Horizantal well 600 30


Please guide, where i am doing mistake.

Note: The model i am using is Horizantal well no-flow boundry.

_-Regards,
