Diagnostic Fracture Injection Tests (DFIT) have become a standard practice in pressure transient testing and in the planning of efficient well stimulation. DFIT’s can be used as a low cost, non-invasive method to determine reservoir pressure, permeability, fracture gradients, and fracture closure pressure to maximize savings on frac designs. Testing across a development area can also help illuminate possible pressure depletion between parent-child wells.
Recording and streaming pressure data of clustered wells that are offset to wells being fractured can reveal inter-well pressure interference/communication in certain zones and can lead to corrective measures to optimize well spacing and maximize production. In a time where it is not uncommon to see several wells drilled on a single pad, monitoring your offset wells for interference is more important than ever.
Whether determining Bottom hole pressure, monitoring overbalance on a low-pressure recompletion, optimizing artificial lift, or even determining pipe restrictions, acoustic shots can be very versatile. It is a non-intrusive way to understand fluid levels and id profiles in wells.
By tying into existing DAQ in van/laptop we provide you with real-time, unbiased, raw data to all your desired treatment channels on Frac, Wire, and Coil vans. RDS frac van monitoring system seamlessly time synchronizes with offset pressure data captured by RDS surface gauges to monitor frac stimulation on adjacent wells.
There are only a few times that you can obtain an accurate reservoir pressure: during a DFIT or when you shut-in a well. If you are shutting in your wells, seize this opportunity to acquire an accurate reservoir pressure. Understanding reservoir pressure is central to improving every part of your strategy—from reserves to completions to production.
