Optimize well-intervention operations and significantly reduce NPT and risk

Baker Hughes combines drilling optimization, real-time downhole measurements, and closed-loop process control to your operations with our SMART intervention service. The service offers valuable information on intervention parameters that have never before been seen at surface, delivering a better understanding of what is happening at the business end of an intervention BHA. With this knowledge, you can make informed, just-in-time decisions that can optimize well intervention operations and significantly reduce NPT and risk exposure.

The enabling technology for the SMART intervention service is the SENTIO™ downhole data acquisition tool based on drilling optimization technology developed by Baker Hughes. The SENTIO tool has sensors that sample critical static measurements. After the data is digitized, a digital signal processor analyzes all data streams simultaneously at a high data rate and outputs static measurements and computed diagnostics.

The outputs are prioritized into job-specific data sequence and transmitted to a rig-floor display screen and, if desired, to a remote real-time operations center. Portions of the information can be recorded and stored in the on-board memory and retrieved later at the surface for detailed evaluation.

The Bi-Directional Communication and Power Module (BCPM) is responsible for the downhole pulsing sequence of the SMART intervention system, recognizing downlinks—surface-to downhole communication—power generation, adjustable circuit breakers, and pulsar control. It provides fast, two-way communication between surface and downhole. The BCPM is the primary power supply and telemetry tool for the SENTIO intervention performance sub. The BCPM works with the Advantage surface system to deliver optimal data telemetry in SMART intervention applications. This innovative design delivers increased reliability in a compact tool.

The SENTIO tool offers advanced SMART Intervention data acquisition and diagnosis technology for all of our 4 ¾-in. downhole tool configurations for 5 7/8-in. casing ID and above. The SENTIO tool’s dedicated sub houses 14 well-intervention process sensors sampled at a high rate. The tool monitors the data stream and diagnoses the occurrence and severity of vibration-related problems, such as BHA whirl, stick-slip, and mill bounce. The dynamic diagnostics are transmitted to the surface via mud-pulse telemetry with static tool data, such as downhole weight overpull, torque, bending moment, and annulus pressure. High-frequency data can be stored onboard over periods of up to 15 min and retrieved at surface for detailed evaluation. The transmitted SENTIO diagnostics and data are displayed on a real-time rig floor display alongside surface data. This feedback about the downhole environment offers a new level of intervention process control. Immediate remedial actions can be taken by changing job parameters; the entire well intervention process can be safely optimized.

The SMART Box is a computer with membrane keyboard, pointing device, 15-in. sunlight-viewable display, and sensor interface combined in a rugged enclosure. When pressurized, it is certified for use in Zone 1 hazardous locations. The SMART Box is a stand-alone MWD decoding system running the latest version of the Advantage software.

The basic system is engineered specifically for SMART intervention services. The unit includes a barrier interface to allow connection of the necessary analog sensors— standpipe pressure, hook load, depth tracking—and acquisition and filter cards to process the MWD telemetry signal. The unit is usually located on or near the rig floor, but can be installed in any remote area of the rig and connected to a LAN via a fiber-optic cable. Wireless communication is available.
