AREAS OF EXPERTISE
WELL TESTING (Pressure Transient Analysis)
A Well Test is a flow experiment carried out in a reservoir. One normally produces a well (sometimes injects fluids) at a constant rate or pressure, then the downhole pressure and surface rates are recorded as function of time. The most common technique is to flow at constant rate and measure the pressure.
​
Why test a well?
Well testing provides information that is not available from static measurements:
-
Dynamic assessment of reservoir geometry
-
Completion efficiency
-
Large-scale dynamic permeability-thickness
-
Large volumes of fluids for PVT and flow assurance
​

​
Pressure Transient Analysis
Interpretation methods are based on the assumption that the system being tested has a certain physical and geometrical structure. The governing flow equations for the assumed system are solved with the production scheme as the boundary conditions.​
CASED-HOLE & PRODUCTION LOGGING
Production Logging
-
Involves logging a well while flowing and shut-in to measure well-bore fluid temperature, pressure, density, holdup, nuclear properties, and velocity
-
Used to diagnose completion problems, infer reservoir properties, and allocate production from commingled zones
Cased-Hole Logging
-
Cased-Hole formation evaluation involves logging a well usually shut-in to measure gamma-ray count rate, neutron porosity, capture cross-section, carbon/oxygen ratio, acoustic velocity, density, and resistivity of the formation behind pipe
-
Used to measure reservoir properties and diagnose reservoir problems
Production Logging provides the following information
-
Water, Oil, and Gas influx or outflow locations. All of which can be used to:
-
Verify completion depth and completion performance
-
Verify water, gas, or solvent breakthrough
-
Identify thief zones
-
-
Fluid-Flow Profile
-
Identify cross-flow and flow behind pipe
-
Allocate flow in commingled zones
-
Identify casing, packer, tubing leaks
-
Identify formation damage
-
Verify well-completion integrity
-
Verify formation fluid contacts
-
PETROPHYSICS
Petrophysics is the study of the physical properties of rocks and fluids. The focus of petrophysics is the region near the wellbore, but petrophysics encompasses a much broader science.
My specialization is integration of core and log analysis, more specifically the use of magnetic resonance to elucidate properties of the rock and the fluids within.
Magnetic Resonance logging tools measure magnetization of hydrogen nuclei (1H) contained in pore fluids (e.g., H2O and CxHy)
-
Hydrogen 1H is paramagnetic, magnetized by permanent magnet
-
Measure magnetization by transmitting & receiving electromagnetic signal at special frequency
Resonance effect
-
Quantum mechanical effect roughly analogous to gyroscope & bar magnet
-
Re-orient magnetic moments by broadcasting radio frequency at resonant frequency f
