Staff Project Engineer 2014 - 2015
ConocoPhillips, Eagle Ford Planning & Strategy Facilities Engineering Group
 Developed Value Optimization Model (VOM) for the Eagle Ford field operations that combines a consolidated total field
process simulation model (using HYSYS) with an extensive spreadsheet containing all of the markets' net equivalent pricing
using several contracts' terms & an overall calculation methodology for lease, trucked oil, stabilized oil, gas (including component
liquids from downstream processing), gas pipeline facilities drip liquids (NGL & atmospheric), and stabilizer plant NGL. Total
Value of all produced fluids is able to be computed for many parametric cases and the Maximum Total Value determined,
permitting optimal separator pressures and temperatures to be set for different reservoir fluid yields and compositions in the
various areas, drip liquid destination including various injection means, and evaluation of stabilization versus well tank trucking
for existing and new wells.
 Member of the Optimization Team to increase efficiency and minimize downtime throughout the ConocoPhillips Eagle Ford
system, primarily by Winterization measures (such as targeted Methanol injection based on accurate hydrate prediction modeling,
and high pressure gas liquid dump line heaters, including field optimization of heater outlet pressure) and Fuel Gas systems'

reduction, vapor recovery, including designs for high-temperature heater treater with oil cooling for "zero" tank vapor emissions
and VRU recycle scheme that also increases oil or total liquid yield; detailed process simulation modeling for downhole, flow line
and facility multi-phase hydraulics and flow assurance assessment for erosion and corrosion.
 Spear-headed sour shale gas well economic solution of high H2S (>2000 ppm H2S) wellsby developing well-to-well small amine
treating/thermal oxidizer scope based on Title V permitting limits rather than continuing to depend on highly expensive
chemical scavenger treatment or on large central gathering and treating plant requiring significantly greater investment at lower
returns and higher complexity in scope (sulfur recovery, storage and handling; carbon dioxide compression, injection or sales;
manned operations)

which have high liquid carryover tolerance due to motions, and packed low pressure stabilizer columns to provide high efficiency
and less motion sensitivity for meeting oil export specifications reliably.
