In turbulent times, optimizing the performance of existing wells is a practical choice that reduces the costs and risks associated with well intervention. Innovative coiled tubing (CT) technologies offer several key benefits, including reduced footprint, accurate measurement of bottomhole pressures and temperatures, proper depth correlation, and precise load measurements, in a unique, robust package for harsh environments and complex systems. This information enables operators to make educated decisions as the job progresses, respond immediately and adjust job parameters as conditions change, and eliminate guesswork.
ACTive live downhole coiled tubing services
ACTive services provide real-time measurements, including internal and external pressure, temperature, casing collar locator (CCL) depth correlation, and distributed temperature measurements, conveyed through fiber-optic telemetry. Resistant to acid and H2S, these real-time CT services give you the opportunity to monitor and evaluate job progress in any well, to optimize treatment results, and to intervene with one trip in hole.
01?Use accurate well diagnostics to make decisions
Customize designed well treatments onsite
The ACTive PTC* live CT pressure, temperature, and casing collar locator tool delivers measurements to surface in real time.
Controlled stimulation requires accurate location and placement of downhole tools.
Real-time pressure, temperature, and casing collar locator measurements improve job efficiency and subsequent well performance.
New proprietary technology enables operators to design an entire treatment based on live monitoring of pressure, temperature, and injection rates. These real-time measurements— including pressure, temperature, casing collar locator, gamma ray, and tension and compression modules—enable operators to accurately determine the depth of the tool end, whether the weight applied on surface is transmitted to bottom, the reservoir response, and whether the pressure applied is adequate.

CT stimulation service helps Saudi Aramco double production?in water-wet wells
An operator needed to use CT to effectively stimulate wells with high water cut and eliminate the risk of increasing water cut due to acidizing. Using the ACTive PTC tool, the operator was able to monitor injection rates and downhole pressure and temperature. This monitoring enabled maximum fluid penetration and successful isolation and stimulation of the oil-producing zone, with a 30% decrease in water cut and 3,000 bbl/d of incremental oil production. The combination of the ACTive PTC tool with DTS allowed for precise monitoring of treatment evolution and on-the-spot job volumes and parameters modifications.
02?Correlate against the formation
Retain pumpthrough capabilities while logging
The ACTive GR* live CT gamma ray logging tool detects gamma rays in the formation in real time while maintaining pumpthrough capabilities for CT interventions.
Using gamma ray data is an effective and accurate way to evaluate a formation and conditions.
Gamma ray tools record naturally occurring gamma rays in the formations adjacent to the wellbore to accurately measure the radioactive content of the formations. Effective in any environment, gamma ray tools are used to correlate logs from cased and open holes.
When combined with ACTive services, this technology enables correlation while maintaining pumpthrough capability for CT interventions. The measurements gathered during depth correlation can be used in conjunction with other CT services to further enhance an intervention’s effectiveness.

CASE STUDY
Overcoming severe drilling damage
While drilling a K-carbonate gas well in the Middle East, an operator encountered high fluid losses due to lost circulation material, which caused severe damage to the near- wellbore formation and had low solubility in acid.
To accurately perform abrasive jetting to place notches that extended through the damaged area, the ACTive GR tool was used to obtain gamma ray measurements in real time and identify the precise depth to perforate in every thin interval with high gas saturation. This information enabled the operator to save time compared with existing conventional methods of depth correlations, which require two separate runs.
This successful placement identified by the ACTive GR tool brought production online quickly to achieve the field’s highest post perforating gas flow.
03 Effectively manipulate wellbore hardware
Detect even the smallest changes in weight downhole
The ACTive TC* live CT tension and compression tool provides downhole load and torque measurements in real time through fiber-optic telemetry.
When a remedial operation is necessary, efficiency is key.
Reducing operational time during CT retrieval and fishing minimizes deferred production and the time and resources wasted while the operation is ongoing. With real-time downhole information, job parameters can be adjusted immediately throughout the intervention.
New tension-compression technology provides downhole load and torque measurements while also maintaining pumpthrough capability. The measurements are conveyed to surface on CT that is enabled by fiber-optic telemetry for faster evaluation and reduced errors

CASE STUDY
ACTive TC tool enables shifting of 10 ICDs in horizontal wells?within 6 hours
An operator needed to access inflow control devices (ICDs) in horizontal wells to confirm opening of sleeves and determine the status of the sliding sleeves during the operation, and wireline was unable to reach the depth of the ICDs. Using the ACTive TC tool, the depth of the CT was correlated to the position of ICDs using the casing collar locator feature. Once the dog collars were confirmed to be open, the ACTive TC tool was moved up and latched onto the ICD sleeve. A total of 10 ICDs were shifted within 6 hours versus more than 12 hours by using conventional toolstrings, and a DTS survey evaluated the opened sleeves.
