Identify unwanted water-entry points, in real time
A major operator in Europe experienced a high production level of unwanted water after opening a new interval in one of its wells. The operator wanted a solution for this long horizontal well in order to identify, in real time, unwanted water entry points from a complex and naturally fractured reservoir, along with subsequent flow behind casing. The well would not flow naturally, and asphaltene buildup in the tubing also had to be addressed. To solve these issues, Halliburton put together an engineered solution that could be deployed in a single trip, comprising the SPECTRUM® FUSION real-time hybrid coiled tubing (CT) service, the Reservoir Monitor Tool 3-Detector™ (RMT-3D™) pulsed-neutron tool, and a production logging tool(PLT).
This customer understood that further remediation was required to improve the water injection rate. Solving this water-entry issue would enable the operator to save significant time and money, thus positively impacting the operator’s field injection strategy across the reservoir.
To achieve accurate water-flow logging, the Halliburton team proposed using its SPECTRUM FUSION real-time hybrid CT service, along with its RMT-3D pulsed neutron tool and a PLT – the first-ever deployment of this combined solution in the industry. This engineered solution would enable a single-trip deployment with a high telemetry rate in real time. To address the asphaltene buildup in the tubing, a special solvent blend was recommended for tubular cleaning via an initial CT run.
Ever deployment of this combined solution
Single-trip, real-time deployment
Rig time saved
The SPECTRUM FUSION service, combined with the RMT-3D pulsed-neutron tool and the PLT, enabled a logging data acquisition program to be successfully executed, with no restriction in the tubing, including for both the drift-run and water-flow logs.
Instead of initially offering a wireline solution, which would have required a separate rig-up, the Halliburton team put together this innovative CT integrated-tool solution. Integrating these tools saved the operator an entire day of rig time and also offered deployment flexibility. By using this CT-based solution, the operator was able to identify the root causes of the water-entry problem and to plan for remedial interventions in order to optimize well production, thus saving time and money.
