Microfracturing Improve Reservoir Management?
Speaker: Mayank Malik, Chevron
Microfracturing is an excellent method of obtaining direct,
in-situ stress measurements, not only in shales, but in conventional reservoirs
as well. Recent advances have shown that microfracturing can help improve
reservoir management by guiding well placement, optimizing injection rates, and
managing perforation strategy.
Microfracturing consists of isolating small test intervals in a
well between inflatable packers, increasing the pressure until a small fracture
forms and then by conducting a few injection and shut-in cycles, extend the
fracture beyond the influence of the wellbore. Results show that direct stress
measurements can be successfully acquired at multiple intervals in a few hours
and the vertical scale nearly corresponds to electric log resolution.
Therefore, microfracture testing (generally performed in a pilot / vertical
well) is an appropriate choice for calibrating log derived geomechanical models
and obtaining a complete, accurate, and precise vertical stress profile.
This talk describes the microfracturing process and presents
several examples that led to increased hydrocarbon recovery by efficient
stimulation and/or completion design. Case studies presented range from
optimizing hydraulic fracturing in unconventionals (Delaware Basin, USA),
determining safe waterflood injection rates in brownfields (Offshore UK), and
helping improve perforation placement in ultra-deepwater reservoirs.
