Reduces carbon emissions by up to 96% in deepwater environments via deep transient testing (DTT) capability
(In an oil well, 2 d flowing at 3,000 bbl/d with drillstem testing [DST] vs. 6 h flowing at 100 bbl/d with Ora platform DTT)
Reduces energy consumption >50% on average because of higher operational efficiency of downhole fluid analysis and sampling operations compared with other wireline formation testers
Ora intelligent wireline formation testing platform comprises four building blocks: new downhole digital hardware, intelligent planning, operations control, and contextual insights to enable
You can now see farther into the reservoir, confirm reserves sooner, expedite your completion strategy, get a head start on your field development plan and facilities design.
The platform’s digital hardware leverages new architecture and metrology to redefine the benchmark in wireline formation testing capability. Rated to 392 degF and 35,000 psi with dual-flowline architecture and featuring smart downhole automation, the platform performs reliably and effectively in all conditions, including tight or unconsolidated formations and challenging fluids.
Wideband downhole pumps precisely govern the broad dynamic range with automated flow management and 0.05- to 108-bbl/d capability. The focused radial probe accesses a large flow area to quickly acquire the cleanest fluids, with contamination below laboratory detection limits. The dual-flowline fluid analyzer quantifies fluid properties with laboratory-accuracy downhole metrology options customized for your objectives: dual-flowline spectrometry, calibrated resistivity, high-accuracy density, full-spectrum viscosity, and highest-accuracy and -resolution pressure gauges.
On average, the Ora platform performs downhole fluids analysis and sampling at more than 50% higher operational efficiency, reducing energy consumption and carbon emissions.
DTT on wireline was conceptualized and developed as a joint project between Schlumberger and Equinor (then Statoil) to bridge the gap between transient wireline formation testing and DST. From its inception, the project's objective was to enable a more sustainable and economical solution for evaluating exploration and appraisal wells at a global scale.
The Ora platform includes DTT capability by design: The platform’s dual-inlet dual packer, highest flow-rate pump in the industry, and patented fluid-handling technology enable DTT on wireline with minimal or no flaring required. The pump’s capacity of up to 108 bbl/d lets you to pump higher volumes, while unique fluid-handling technology enables active hydrocarbon circulation to surface for well control, so you can test longer. And with advanced sensor technology, you can see deeper into your reservoir.
The DTT service of the Ora platform is a proven, alternative solution for determining minimum hydrocarbon in place and zonal deliverability in reservoirs where DST is restricted because of cost, time, emissions, or environmental regulations. DTT on wireline is also used to optimize DST design and operation, further minimizing DST emissions.
In deepwater offshore Africa, the Ora platform DTT service on wireline enabled an operator to confirm oil production deliverability and book reserves. Compared with a conventional DST, the DTT operation reduced greenhouse gas (GHG) emissions by 96%—5,504 t of carbon dioxide equivalent. This is comparable to removing GHG emissions from 436,905 passenger vehicles driven for one day or 1,197 passenger vehicles driven for one year.
