Deep transient testing on wireline

Determine hydrocarbons in place, zonal deliverability, and commercial viability with zero flaring

Ora, DTT, Deep transient testing

Contextual formation insights with lower carbon intensity

Performed using the Ora™ intelligent wireline formation testing platform, deep transient testing (DTT) increases the radius of investigation to provide a greater understanding of reservoir fluids in exploration, appraisal, and development. Deployed on wireline, DTT evaluates each zone while maintaining continuous downhole monitoring for well control. Now you can determine minimum hydrocarbons in place, estimate zonal deliverability, and prove commercial viability where drillstem testing (DST) is restricted because of time, costs, footprint, or environmental regulations.

At the forefront of formation testing

Bridging the gap between conventional wireline formation testing and DST, DTT provides efficient pumping, sampling, downhole fluid analysis (DFA), and pressure measurements across a wide range of reservoir and fluid properties, including previously impossible conditions such as HPHT formations. With laboratory-accuracy downhole metrology, 108-bbl/d flow rate capabilities, and patented fluid handling technology, DTT enables you to pump higher volumes, analyze purer fluids, test longer, and see deeper into the reservoir—all with zero flaring.

Comprehensive dynamic reservoir evaluation

When used together, DTT and DST enable dynamic reservoir evaluation that delivers critical answers about flow, connected volumes, reservoir producibility, and more. Leveraging advanced workflows and intelligent interpretation, dynamic reservoir evaluation data is contextualized and visualized in real time. Within hours of data acquisition, you can confirm reservoir mobility, optimize DST designs, and make confident decisions about completions, sidetracks, and field development.
