04 Extend zonal isolation with robust multisetting，Overcome well and environmental challenges in real time.
The ACTive Straddle* CT real-time multiset inflatable packer extends critical through-tubing zonal isolation to previously inaccessible environments with a reliable multiset mechanism.
Difficult-to-access, chemically harsh, and high- temperature environments can still benefit from effective zonal isolation.
Accurately placing treating fluids for acid stimulation, water control, gas shutoff, and chemical treatment in harsh environments is difficult and requires rugged, reliable technology.
With a robust multiset mechanism, these packers can perform repeated remedial operations without killing the well. The latest packers are also resistant to chemicals, enabling treatment in previously inaccessible wells.

CASE STUDY
ACTive Straddle inflatable packer cleanout doubles production in two wells
With more than 20 ICDs in each well, Kuwait Oil Company (KOC) needed to identify and selectively treat the problematic ICDs and restore production with minimal downtime.
Using ACTive Straddle packer in combination with the ACTive DTS Inversion* distributed temperature measurement analysis, KOC identified, isolated, and selectively treated the plugged ICDs in a single run in each well, saving more than one week of rig time, increasing production from Well A by 150%, increasing production from Well B by 171%, and producing 50,000 bbl of oil.
05 Perforate more efficiently and reduce risk
Avoid deferred production and killing the well when reperforating
The ACTive OptiFIRE* CT real-time selective perforating and activation system provides a safer, more economical, and more efficient method for perforating with CT.
Properly perforating or reperforating a well can make a dramatic difference in production.
A successful perforating intervention enhances production in new or existing intervals. However, conventional methods for perforating with CT often require multiple runs, experience perforating head limitations, and lack confirmation of detonation.
Schlumberger has advanced CT perforating technology to selectively perforate up to 10 zones in a single run and provide real-time confirmation of detonation downhole. These improvements enable the system to enhance intervention safety, eliminate the need to pump fluid to detonate, and reduce perforating time.
APPLICATIONS
- Selective, underbalanced, and live well perforating
- Tubing punching
- Plug setting
FEATURES
- Ability to fire up to 10 zones in a single run
- Selective perforating capabilities
- Robust selective-firing multiple-gun system for single-run efficiency
- Capability of addressing pumping issues in subhydrostatic wells
- Improved safety from addressing each gun with advanced switches
- Reduced footprint
- Real-time pressure and temperature for optimized fluid placement and hydrostatic pressure control
- Fast-acquisition accelerometer for detonation confirmation
CASE STUDY
Underbalanced perforating technology reduces deferred production and intervention time
To prevent deferred production and remove formation damage, Pemex needed to perforate two new intervals and reperforate a critical zone on a live well in underbalanced conditions. Schlumberger deployed the ACTive OptiFIRE system, a first-of-its-kind coiled tubing technology that eliminates the need for a ball-drop or pressure-pulse system to activate shaped charges. Using advanced fiber-optic technology, Schlumberger accurately placed the perforating guns, activated the charges without a ball-drop or pressure-pulse system, and confirmed downhole detonation in real time.
BENEFITS
- Greater Safety and Certainty
- Real-time detonation confirmation
- Detonation without fluids or balls
- Accuracy
- Casing collar locator and gamma ray correlation
- Flexibility
- Selective perforating of multiple guns
- Efficiency
- Lighter than conventional CT electric line reels, with better extended reach and ability to pump acid
06 Integrate wireline production logging capabilities with CT
Improve logistics with less equipment
The ACTive PS* live CT production logging service couples real-time fiber-optic telemetry with existing wireline production logging tools to acquire data in real time.
Acquire evaluation, design, diagnostics, and optimization data in just one trip to the wellsite.
Traditional CT production logging operations require a logging cable–equipped CT string and a standard logging unit, which typically accounts for an additional conventional CT reel for intervention operations before and after the loggingis performed.
The use of fiber-optic telemetry enables any kind of workover intervention to be performed. Data is sent wirelessly from the working reel to the acquisition and interpretation computer on the surface, so no surface logging unit is needed on location. Production logging can be acquired in real time, so reservoir and production measurements can be interpreted for subsequent interventions—where they matter most.
APPLICATIONS
- CT and extended-reach logging
- Wireline production logging operations using PS Platform* production services platform, Flow Scanner* horizontal and deviated well production logging system, and RSTPro* reservoir saturation tool
- Nitrogen kickoff
- Well stimulation
- Onsite evaluation
- Wellbores inaccessible by wireline
FEATURES
- Real-time fiber-optic telemetry
- Wireless data conveyance
- Self-contained technology
- Faster, higher-quality data
- Real-time data evaluation
- Simplified logistics
- Compatibility with PS Platform platform and DTS
BENEFITS
- Real-time fiber-optic telemetry coupled with existing wireline production logging tools for the best live CT production logging service
- Fully self-contained technology with no wireline unit to reduce footprint
- Fewer crew members required due to minimal equipment use
- High-quality onsite evaluation, well stimulation design, real-time treatment diagnostics, and well production optimization in just one trip to the wellsite
CASE study
ACTive PS service reduces rig operational time by 10 days during plug setting and well cleanout
An operator needed to perform production logs and matrix stimulation operations, as well as shut off H2S and water-producing zones
in extended-reach wells with major logistical constraints. The operations required a single piece of equipment to fit on the small platform and preventing swapping our units during the operation.
Using the ACTive PS service, the operator was able to perform production logging operations using PS Platform platform and Flow Scanner system. Alternating the use of ACTive PS service and ACTive PTC tool saved the operator multiple runs and equipment changes, including a total of 10 days in rig operations with a total of 16 runs performed in 7 wells within 2 months.
