The past few years
have not been an easy on the Oil & Gas industry. Many processes and
operations have needed to adapt to lower oil & gas prices, caused in part
by the COVID-19 pandemic. Understanding reservoir producibility and proving
reserves are key to generating a Reservoir Development Plan (FDP). However, the
different processes to obtain such answers are strongly dependent on cost. The
value of information is extremely important for operators to decide whether to
proceed with their discoveries.
In an Interval
Pressure Transient Test (IPTT) or known as mini-DST have been widely used in
the past 20 years, especially in combination with dual packers, and more
recently with single packers. Operation efficiency and safety have improved
significantly. This presentation will discuss the IPTT concept and field
applications including the IPTT limitation for both probe and inflatable
packers.
Second part of this
presentation, a Deep Transient Testing (DTT) will be introduced by closing the
gap between IPTT and traditional Well Testing methods. With DTT’s, we can flow
with wider range of flowrate and longer time than previously possible with
Wireline formation testers, enabling pressure transient analysis in different
quality of reservoirs. Further data quality improvements come from new, high
resolution of gauges deployed with an Intelligent Wireline Formation Testing
Platform. This presentation includes a review of the DTT method with several
field examples. The benefit of wide range of rate can help to extend the DTT
application to tight and ultra tight formations. In addition, the safe, greener
testing technology can help us to follow the United Nation Sustainability
Development Goal.
