How DeepLook-EM Crosswell Resistivity Works

To directly measure reservoir resistivity between two wells up to 3,280 ft [1,000 m] apart, the 32.4-ft [9.88-m] DeepLook-EM transmitter antenna in one well broadcasts a continuous sinusoidal signal at a frequency from 5 Hz to 1 kHz, selected by modeling and simulation of the borehole environment, well separation, and formation resistivity. The magnetic moment produced by the transmitter is 100,000 times stronger than the source in a conventional single-well induction logging system.

The transmitter signal induces electrical currents to flow in the formation between the wells. The currents, in turn, induce a secondary magnetic field related to the electrical resistivity of the rock. At the receiver borehole, the DeepLook-EM array of four coil receivers detects the primary magnetic field generated by the transmitter as well as the secondary magnetic field from the induced currents.

For each receiver station, the transmitter in the other well traverses the interval of interest at a logging speed of 2,000 to 5,000 ft/h [600 to 1,520 m/h]. Once a complete transmitter traverse, or profile, is collected for a receiver position, the receiver tool is repositioned, and the process is repeated.

Once all the receiver positions have been logged, the DeepLook-EM interwell resistivity distributions are exported to a field model compiled using Petrel seismic-to-simulation software. The resulting data integration and interpretation provide critical crosswell insight for fluid tracking of water and steam, detecting bypassed pay, and optimizing reservoir characterization.

Deep Reading Technologies

Enhanced Interwell Resolution Through Crosswell Imaging

The Schlumberger Deep Reading initiative helps you better understand your reservoir by using direct physical measurements of the interwell space. Crosswell electromagnetic imaging and crosswell seismic imaging take you beyond the confines of the near-wellbore volume to illuminate the wider reservoir volume for numerous applications:

  • Reservoir characterization: higher resolution measurements of porosity, lithology, and resistivity within an expanded scope of fluid identification, structure determination, and detection of bypassed pay
  • Fluid front monitoring: water, steam, and gas injection, CO2 sequestration, and permanent monitoring of production and injection.

DeepLook-CS

Crosswell seismic imaging

Crosswell seismic imaging of reservoir layers delivers up to 100 times the resolution of surface seismic data by placing both the receivers and source in adjacent wells and imaging the interwell volume. Both direct arrival and reflected information can be processed to provide a detailed subsurface image of the reservoir or zone of interest. Crosswell seismic data improves the understanding of the reservoir geometry and rock properties from the reflection seismogram and details of fluid migration, including steam chambers, from both the velocity tomography and reflection seismogram.

DeepLook-EM

Crosswell Electromagnetic Imaging Service

Crosswell electromagnetic imaging expands the scale investigated by resistivity logging to deliver the big picture. By monitoring fluid distribution and movement on a reservoir scale, EM imaging with the DeepLook-EM system gives you information critical to optimizing sweep efficiency and identifying bypassed reserves.

How it works

Conventional logging is restricted to the near-wellbore volume. The DeepLook-EM enhanced crosswell electromagnetic imaging system illuminates the wider reservoir volume with a transmitter tool deployed in one well and a receiver tool deployed in a second well. EM imaging can be conducted between two wells located up to 1,000 m apart, depending on the well completions and the formation and resistivity contrasts.

Wireline Conveyance

As well geometries become increasingly complex they present a growing challenge for conveyance. Integrated wireline deployment systems bring the efficiency of wireline operations to deep and highly deviated wells that were previously not wireline accessible. Alternative conveyance of most logging tools on drillpipe, coiled tubing, or wireline tractors is also available to address a wide range of well conditions.

High-Tension Conveyance System

The Schlumberger high-tension conveyance system leads the industry in delivering the strength and efficiency of wireline operations to ultradeep wells. The system pairs high-strength cable with specialized surface equipment to reliably manage high-tension wellbore conditions and improve operational safety for record depths, highly deviated well paths, complex trajectories, and sticking mitigation.

Wireline Deployment

Schlumberger wireline deployment systems provide reliable, efficient conveyance even for deep and complex well trajectories, helping operators avoid costly pipe conveyance and fishing operations. Our super ultrastrength (SUS) cable is the industry’s strongest, deployed with surface equipment specialized for high-tension operations.

Rt Scanner Triaxial Induction Service

Rt Scanner triaxial induction service calculates vertical and horizontal resistivity (Rv and Rh, respectively) from direct measurements while simultaneously solving for formation dip at any well deviation. Making measurements at multiple depths of investigation in three dimensions ensures that the derived resistivities are true 3D measurements. The enhanced hydrocarbon and water saturation estimates computed from these measurements result in a more accurate reservoir model and reserves estimates, especially for laminated, anisotropic, or faulted formations.

The compact, one-piece Rt Scanner tool has six triaxial arrays, each containing three colocated coils measuring at various depths into the formation. Rv and Rh are calculated at each of the six triaxial spacings. Three single-axis receivers are used to fully characterize the borehole signal to remove it from the triaxial measurements. In addition to the resistivity measurements, formation dip and azimuth are calculated for structural interpretation.

Along with advanced resistivity and structural information, the Rt Scanner tool delivers standard AIT array induction imager tool measurements for correlation with existing field logs. The tool’s innovative design provides this complete resistivity information with no additional hardware. The Rt Scanner tool is also fully combinable with Platform Express and most openhole services.

Isolation Scanner Cement Evaluation Service

Isolation Scanner cement evaluation service combines classic pulse-echo technology with a new ultrasonic technique—flexural wave imaging—to accurately evaluate any type of cement, from traditional slurries and heavy cements to the latest lightweight and foam cements. This innovative method provides real-time evaluation of cement jobs in a wider range of conditions than previously possible with conventional technologies.

The tool's combination of independent measurements differentiates low-density solids from liquids to distinguish lightweight, foam, and contaminated cements from liquids. Its azimuthal coverage provides an answer around the entire circumference of the casing, pinpointing any channels in the cement and confirming the effectiveness of a cement job for zonal isolation. Isolation Scanner service also identifies corrosion or drilling-induced wear through measurement of the inside diameter and thickness of the casing.

Flexural wave imaging

The addition of the flexural measurement produces an entirely new piece of information yielding potential insight for certain applications. With analysis in addition to the cement evaluation, flexural reflections from the third interface may also define the position of the casing within the borehole or outer casing. Previously unavailable cased hole–environment geometrical information can help assess casing and cementing techniques, choose cut points on casing retrieval jobs, and provide context for other evaluation services run through casing.

Applications

  • Differentiate high-performance lightweight cements (foam, LiteCRETE and Ultra LiteCRETE slurry systems) from liquids
  • Map annulus material as solid, liquid, or gas (SLG map)
  • Confirm hydraulic isolation
  • Identify channels and defects in annular isolating material
  • Determine casing internal diameter and thickness

Flow Scanner

Diagnose your three-phase flow, downhole

Optimized for three-phase production logging, the Flow Scanner horizontal and deviated well production logging system makes unique, direct measurements by using sensors in contact with the phases. Regardless of phase mixing of recirculation, your complex flow regimes are quantified and profiled in real time to give you a better understanding of downhole phase dynamics.

Conventional production logging tools, developed for vertical or nearly vertical wells, cannot give effective answers when confronted with the complex flow environment of highly deviated wells. Flow Scanner service can. Innovative electrical probes distinguish water and hydrocarbon buildup and optical probes differentiate gas and liquid holdup to fully measure three phases.

The Flow Scanner tool measures phase velocity for calculating a multiphase velocity profile. By combining the velocity and holdup profiles, you can calculate multiphase flow rates in real time, maximizing well production.

Fully combinable with other cased hole logging tools, the system operates in temperatures and pressures up to 300 degF and 15,000 psi. The system can be run in hole sizes ranging from 2 7/8 in to more than 9 in on wireline, coiled tubing, or as an integral part of our MaxTRAC downhole well tractor system.

Case studies: Exact production profiles

In the Gulf of Suez, conventional production tools failed to see oil entries because of adverse effects of highly viscous oil and unstable slugging from a 37° well flowing about 2,000-bbl/d oil with a 97% water cut. Reworking the well depended on an accurate production profile showing the precise location of the oil and water entries. Flow Scanner logging produced a reliable inflow profile, free from the unfavorable effects encountered previously.

In another Middle East example, the Flow Scanner system identified water recirculation along the wellbore completion to 100 ft from surface. The operator conducted a workover to circulate out these remnant completion fluids, effectively unchoking the well and significantly increasing hydrocarbon production.

EM Pipe Scanner

Electromagnetic casing inspection

EM Pipe Scanner electromagnetic casing inspection tool combines a slim mandrel with 18 pad sensors to quantitatively scan the interior surface and thickness of production casing. The slim mandrel enables measuring casing corrosion and identifying grooves and splits without having to first pull the completion tubing, saving significant time and cost.

As it descends in the well, the EM Pipe Scanner tool conducts a high-speed reconnaissance run to flag places of interest for subsequent diagnostic scans as the tool ascends. The diagnostic images identify the exact severity and nature of the corrosion. The versatile tool is fluid insensitive, operating in liquid or gas environments, and can be deployed by wireline, tractor, or coiled tubing at up to 90° well deviation. Time-lapse deployment provides corrosion rate estimates, identifies casing corrosion behind tubing, and determines the inner tubular radius behind scale.
