Transcript of EMPC Final Intern Presentation
This presentation includes forward-looking statements. Actual future conditions (including economic conditions, energy demand, and energy supply) could differ materially due to changes in technology, the development of new supply sources, political events, demographic changes, and other factors discussed herein (and in Item 1A of ExxonMobil’s latest report on Form 10-K or information set forth under "factors affecting future results" on the "investors" page of our website at www.exxonmobil.com).

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

Background
• Born: Dover, Delaware
• Hometown: America
• School: New Mexico State University – May 2016
• Degree: Chemical Engineering
• Past Experience:• NMSU Aggie Innovation Space• NMSU Reduced Gravity &
Biomechanics Lab
• Involvement: American Institute of Chemical Engineers, Tau Beta Pi

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.
