Fuel/electricity consumption units for stabilization and dewatering

[qlangfitt]

On both the Crude Oil Stabilization and Crude Oil Dewatering sheets, there are unit issues for the fuel consumption calculations. For the NG consumption there is an IF statement that would always lead it to show as kWh/d, though the units actually are always mmbtu/d. For the electricity consumption, eta_S_el and eta_heater_treater_electric have units of kWh/btu on the secondary inputs sheets. However, the calculation sheets treat it as if it is in kWh/mmbtu. To add to the confusion, looking at the default value, it seems like the unit actually represented (default=0.23) is probably MWh/mmbtu.

• Fixed!
• divided cells N137 and N146 of Secondary Input sheet by 1000 to set the unit as kWh/btu

Adam: I fixed them, but as many unit conversion mistakes occurred I suggest you take a secondary look.

@smasnadi There is still an issue remaining - actually discovered this when fields with high GOR were suddenly not exporting any gas. On the Crude Oil Stabilization sheet, Stabilizer column NG consumption (M48) was fine how it was before: =IF(Type_S="Gas",M47/Eta_S_fg,0). What I was asking to be changed was the cell next to it showing the units (N48). That cell is and was set up to show kWh/d, but the equation calculates in mmbtu/d. I was asking for the unit cell (N48) to be changed from kWh/d to mmbtu/d. Hopefully that makes sense.

The changes you made to the secondary inputs and to the stabilizer column electricity consumption look good to me.

Fixed issue as recommended by Quinn above for crude oil stabilization. @arbrandt please take a look at unit conversions as pointed out my Mohammad

I cleaned these up as the unit conversions were complex. They are simpler now and all check out.
