274 Principles of Applied Reservoir Simulation

K = layer absolute permeability (md)
h = layer thickness (ft)
DX = x direction gridblock length (ft)
DY = y direction gridblock length (ft)
~ wellbore radius (ft)
r w
r 0 = equivalent well block radius (ft)
S = layer skin factor

Deviated (slanted) and horizontal wells may be represented by
calculating an appropriate PID and specifying gridblock locations that
model the expected well trajectory. For example, a horizontal well that
is aligned in the x direction will have constant J and K indices, and index
I will vary if there is more than one connection.
To shut in a connection, set that connection PID to 0. To shut in
a well, set all of its connection PID values to zero.

7. KIP, QO, QW, QG, QT
Omit this record ifNWELLN = 0.
KIP Code for specifying well operating characteristics.
Rate Controlled Well (KIP > 0):
QO Oil rate (STB/D).
QW Water rate (STB/D).
QG Gas rate (MSCF/D).
QT Total fluid voidage rate (RB/D).
NOTE: The total fluid rate given by QT is the oil plus water plus
gas production for the well or the total reservoir voidage rate at
reservoir conditions. For multi-layer systems, QT is a target rate.
BMP Controlled Production Well with Optional Rate Constraints
(KIP = -1):
QO Minimum oil production rate required (STB/D).
QW Maximum oil production rate allowed (STB/D).
QG 0.0
QT Maximum liquid withdrawal rate allowed (STB/D).
