Advanced Log Interpretation in Field Development
by: Richard Merkel, Denver Petrophysics, LLC
The authors were involved in a
project in the Monument Butte field in the Uinta Basin to evaluate the
potential of reducing vertical well spacing from 20 acres to 10 acres in a
field where a secondary water flood has been in effect since 1987. Water injection
is co-mingled in the 25 highly discontinuous fluvial sand bodies in the Lower
Green River formation.
The initial objective of the study
was to test ifdielectric logs could identify where
the low salinity water flood breakthrough occurred in infill wells. Since
dielectric log interpretation gives bulk volume water (BVW) somewhat
independent of water salinity, we hoped to identify sands with breakthrough of
low-salinity injection water so engineers could avoid these zones when
completing infill producing wells. We designed an initial testing program using
dielectric, NMR, and triple combo data combined with rotary sidewall core and
The added dielectric logging,
core, and pressure data on infill wells met the original objectives, but also
were used to determine numerous additional reservoir properties in the pay
interval such as: 1) wettability, 2) relative permeability, 3) Archie saturation
exponents, 4) better OIP calculations, 5) residual oil saturation (Sor), and 6)
reservoir pressure (depleted, native state, and water flood over pressure).
Each of these factors provided input in the zone completion of the infill oil
producers, as well as which wells and intervals should be converted from
producer to injector. Examples show the log response, analysis, and results in
the independent and/or isolated producing sands in Monument Butte. Also shown
is how RFT down hole pressure measurements and core analysis aided and verified
Dick Merkel is President of Denver Petrophysics LLC, which is a consulting firm dedicated to developing logging analytical techniques for petrophysical models tied to core, completion, and production data in complex reservoirs. Previously, he worked at Newfield Exploration Company where he worked on teams that developed reservoir models for unconventional oil and gas reservoirs in the Rocky Mountains. Prior to its closing in 2000, he was a Senior Technical Consultant at Marathon Oil Company's Petroleum Technology Center in Littleton, CO where he worked for 13 years on evaluating new logging tools and technology, and developing techniques for their application in Marathon's reservoirs. Dick holds a BS in Physics from St. Lawrence University and a MS and Ph.D. in Geophysics from Penn State. He is a past president of SPWLA, the SPWLA Foundation, and DWLS, and is currently a member of SPWLA, SPE, and SCA.
