Brief

Enhancement List is a workflow for identifying the performance gaps based on the Gap Analysis.

The workflow produces the Enhancement List which is a ranking of the Enhancements with the best on the top.

Routine execution of the identified Enhancements unlocks the pathway to Production Potential and results in more production, improved recovery and increased earnings.

WHP and WOP

WHP POTENTIAL is calculated by by setting the WHP equal to the current FLP.

"WO POTENTIAL" is calculated by using the largest tubing practical that will fit in the current well bore with a WHP equal to current line pressure.

две ветки: flowing (tub, ann, tub+ann) not flowing (или ESP или PCP и тп) две категории: ENHANCED WO ENHANCED по flowing: ENHANCED - так же как в Gas Enh List WO ENHANCED - AOF по not flowing: ENHANCED - считаем BHP при Hd=Htub, считаем ql для этого BHP через IPR WO ENHANCED - AOF для JD при расчете AOF: GAS - if JD<0.13 JD=0.13 else JD OIL - if JD<1.27 then JD=1.27 else JD

Misha, I think that we need two potential calculations(columns) for flowing wells:

1. "WHP POTENTIAL" is calculated

     by by setting the WHP equal
     to the current line pressure at the
     well head. Use estimated current
     Jd.

2. "WO POTENTIAL" is calculated by

     using the largest tubing practical
     that will fit in the current well bore
     with a WHP equal to current line
     pressure. Use a Jd ~ 0.13. The
     assumption is that we will mitigate
     the current skin with better 
     completion during the workover. 
     The largest tubing size is
     approximately the casing drift
     diameter minus the tubing
     coupling diameter > 0.75
     Inches for clearance. Then 
     convert this to the nearest 
     standard tubing OD, 2 7/8, 3 1/2,
     4, 4 1/2, 5, 5 1/2, 6, 6 5/8, 7,
     7 5/8, etc,

The potential gap should be sorted

based on the "WHP POTENTIAL"
since this is the easiest and cheapest
enhancement to execute.

Your horseshoe should be based

on the "WO POTENTIAL" since this
Is the actual potential of the currently
constructed well bore.

You should always display AOFs

in one of the columns.

These rules apply to all flowing

wells unless the workover installs
artificial lift of some sort.

Artificial lift is a different sheet and we can spec it later, since it doesn't apply to us at this time.

Production Potential is used to rank the Enhancements.

Below is the Production Potential calculation logic of the E&P Portal:
