Real-Time Injection Diagnostics and Treatment Evaluation
HOUSTON: The global supplier of integrated project management solutions, Schlumberger recently unveiled its novel and innovative ACTive Q* CT real-time downhole flow measurement service. The new service aims at delivering real-time injection diagnostics and treatment evaluation in a single run in a well. The ACTive Q service also features distinct capabilities like fiber-optic telemetry and calorimetric flow measurements.
Through the ACTive Q* CT real-time downhole flow measurement service, Schlumberger intends to conduct assessment on the absolute flow rate contribution to each interval. Further, ACTive Q* CT adjusts the pumping schedule as needed for diversion and subsequent stimulation stages. ACTive Q service also delivers the measurements in the fluid velocity in order to expand the coiled tubing downhole monitoring capacities. Speaking about the service Amerino Gatti, president, Well Services, Schlumberger says, “Fluid injection monitoring and placement often requires customers to reach conclusions through trial and error or time-consuming logging operations”.
Citing an instance, the Kuwait Oil Company (KOC) was required to efficiently target those requisite sections that needed stimulation or diversion while avoiding additional logging runs. This was after the water injector well in Sabriya field displayed decreasing injection rates with steep increase in the wellhead pressure. With the ACTive Q service, two primary thief zones at each extremity of the well were spotted. Furthermore, the services unique capacity of combining the real-time monitoring, injection profiling, and acid stimulation in a single run reduced the number of work hour operations by three days. “With the ability to measure pressure, temperature and fluid velocity in real-time during interventions, the ACTive Q service improves customers’ understanding of downhole wellbore and reservoir behaviors. This helps facilitating customers’ decision making and improvise the effectiveness of treatment placement,” remarked Gatti.
