Agenda

• Safety Moment

• Background

• Projects

• Other Experiences Gained

• Lessons Learned

• Questions

Proprietary 3

Safety Moment - H2S Detection

• What happened?• Goldsmith Tract 2 Gas Leak

• H2S Monitor Alarmed

• Awareness:• Be aware of your surroundings• Always know the wind direction • Test the monitor each time you use it

• What is the proper monitor placement?• Always place monitor at or

near your face as to detect any H2S presence

• Make sure sensor is not obstructed by clothing and facing outward

Project Assignments - XTO

• MPZ/ROZ Expansion • Field: Means• Location: Andrews, TX• Facility: Sub-Battery 228

• University Block 20 Expansion• Field: Monahans• Location: Wink, TX• Facility: University Block 20

Proprietary 6

Means Field• History

• 1934 – Discovered • 1963 – Start Water Flood

• 1983 – Start CO2 Flood

• Main Pay Zone / Residual Oil Zone• Re-developing the MPZ

• Expanding CO2 into ROZ

• Expansion will increase oil production from 6,000bpd to 13,000 bpd

• Cost• Total Investment: $635 Million ($440 already

funded)

XTO - MPZ/ROZ Expansion

• Scope:• Determine capacity of current

facility • Determine facility design

required for forecasted rates

• Findings:• Concluded that Sub-Battery 228

will experience bottlenecking due to the current piping

• The forecasted gas production requires significant facility upgrades

XTO University Block 20 Expansion• History:

• University Land• Drilling started 2 ½ years ago• Better production than expected

• Plan:• 4 wells are planned• Additional separation and

treating required to meet forecasted production

• Scope:• Locate potential tie-ins• Determine appropriate sized

vessels• Determine line sizing

Lessons Learned

• Value of a hands on experience• Importance of traveling to the

field

• Efficiency of asking an expert

• Importance of engaging operations during design• Unforeseen issues not yet

considered

• Learning to be aware of the larger scope

Thank You, Any Questions?

Take the attitude of a student, never be too big to ask questions, never know too much

to learn something new.
