Palantír—The Ecosystem of Clear Seeing
Five sensing layers — acoustic, flow, temperature, depth, and electromagnetic — that measure what moves, what holds, and what threatens. From the first formation log to the final abandonment barrier.
About
DeltaSense
Sensors that measure.
Platforms that answer.
DeltaSense provides advanced sensor systems and digital intelligence for well integrity assessment — from drilling through to decommissioning.
We combine hardware you can trust with platforms that turn raw data into actionable answers. Every measurement serves a purpose. Every answer drives a decision.
Our sensor systems span the full well lifecycle — from openhole formation evaluation and MWD directional drilling through to cased hole integrity and plug & abandonment. All powered by Palantír: our Ecosystem of Clear Seeing, built on five intelligent measurement layers that turn raw data into decisions.

The Products
Four specialised tools. Each purpose-built.
PulseVista
Cement, Casing & Formation Evaluation
Ultrasonic family of active acoustics tools for cement, casing and formation evaluation. Delivers high-resolution, non-radioactive imaging of bonding quality, casing condition and annular integrity.
Capabilities
- →360° quantitative cement impedance mapping
- →Casing condition — wall thickness, corrosion, deformation
- →Micro-annuli and channel detection beyond sonic resolution
- →Zonal isolation verification for completion and P&A
ApexHunter
Multi-Sensor Well Integrity Diagnostics
Purpose-built for hunting leaks throughout the well system. Combines multiple sensing layers to pinpoint leak paths, quantify flow and confirm barrier performance with precision.
Capabilities
- →Leak detection and source pinpointing throughout the well system
- →Flow quantification — rate, direction, and active fluid movement
- →Thermal anomaly mapping for barrier and communication assessment
- →Multi-physics convergence for unambiguous, defensible diagnosis
CiQ
Conformance, Integrity & Quantification
Specialised for production evaluation — delivering clear insight into conformance, zonal contribution and flow integrity behind pipe and between zones. The definitive product of high end modules to assess the production system of the well aligned to the customers objectives.
Capabilities
- →Zonal flow contribution and conformance profiling
- →Flow integrity and behind-casing communication assessment
- →Production allocation and injection conformance quantification
- →Reservoir management insight for targeted intervention
Aulë
Electromagnetic Tubing Integrity
Electromagnetic technology for multiple tubing wall thickness measurements. Provides accurate, multi-string wall thickness evaluation to assess metal loss and tubing integrity across single and multiple concentric casings.
Capabilities
- →Multi-string simultaneous wall thickness evaluation
- →Metal loss detection across concentric casing strings
- →Corrosion and defect mapping in complex completions
- →Tubing integrity assessment without pipe movement
The Ecosystem
Palantír
—The Ecosystem of Clear SeeingPalantír sits above the products as the unifying intelligence layer. It takes every measurement from PulseVista, ApexHunter, CiQ and Aulë and transforms it into clear, decision-ready answers. From raw multi-physics data to a single, coherent view of the well.
How it works
Palantír
Intelligence Layer
Multi-physics to single answer
Convergence of acoustic, thermal, flow and EM data into one coherent well view.
Full coverage
Cement evaluation → casing inspection → leak detection → reservoir flow → tubing integrity.
Static + Dynamic + Quantification
Covers every diagnostic mode — structural, active, and quantified.
Answer-first interpretation
Clear, decision-ready outputs — not raw logs. Delivered through the Palantír platform.
Powered by
Five intelligent sensing layers
The Products and the Palantír Ecosystem are underpinned by five specialised digital platforms. Together they form the foundation that makes every diagnosis sharper and every answer more certain.
Ulmo
Acoustics
Full-spectrum acoustic processing — from ultrasonic pulse-echo to broadband noise analysis. Resolves cement quality, casing condition and leak signatures across the complete acoustic range.
Anduin
Velocity / Flow
Precision flow measurement and velocity profiling across the well system. Quantifies fluid movement, direction and rate — separating active dynamic signatures from static background.
Arien
Temperature
High-resolution thermal sensing that maps temperature anomalies and gradients with precision. Identifies fluid movement, Joule-Thomson effects and barrier performance in real time.
Durin
Base / Depth & Events
Precision pressure, depth and event capture that anchors every measurement in space and time. The reference layer that gives all other data its context, accuracy and certainty.
Aulë
Electromagnetic
Multi-frequency electromagnetic sensing for metal evaluation across single and multiple casing strings. Measures wall thickness, detects metal loss and maps corrosion through complex completions.
Where We Deploy
Applications

Plug & Abandonment
The final chapter of a well's life demands absolute certainty. Regulators require verifiable cement quality, confirmed zonal isolation, and proof that no fluid is moving where it shouldn't. DeltaSense brings complementary solutions to the P&A arena — delivering the complete diagnostic picture operators need before committing to permanent abandonment.
Synergy
Two tools. One complete answer.
Confirms the structural quality of the cement and casing. Quantitative 360° imaging maps cement bond quality, detects micro-annuli and channels, and verifies casing condition — giving operators and regulators a trusted picture of the permanent barrier before plugs are set.
Confirms there is no dynamic fluid movement behind pipe. Multi-physics diagnostics — acoustic, thermal, flow, and density — detect and quantify any active leaks, cross-flow, or channeling that would compromise the barrier. If something is moving, ApexHunter will find it.
Verify the Barrier
Before you seal a well, you need to know the barrier holds. PulseVista's 360° ultrasonic imaging maps cement quality and casing condition across every inch of the abandonment interval — confirming integrity or revealing exactly where remediation is needed.
- •Quantitative cement maps regulators trust
- •Detects micro-annuli sonic tools miss
- •Casing corrosion and defect assessment
- •Works across wide casing sizes (4"–18¾")
Hunt the Leak
If something is leaking, ApexHunter will find it. Multi-sensor diagnostics converge to pinpoint the exact source, depth, and severity of any leak path before permanent plugs are set — through existing tubing, without pulling the completion.
- •Through-tubing operation saves rig time
- •Leak threshold down to 0.05 scf/hr
- •Non-radioactive options available
- •Ideal for “quiet well” pre-abandonment surveys
Combined Campaign
Run both in a single e-line campaign
PulseVista and ApexHunter share compatible DeltaSense architecture, enabling single or back-to-back e-line deployment. This combination is particularly powerful for mature wells, offshore P&A campaigns, and fields with complex history where traditional cement evaluation alone may not be sufficient.
Comprehensive Evidence
Full barrier verification for P&A program approval.
Remedial Clarity
Clear identification of any squeeze jobs or remedial work required.
Reduced Rig Time
Single campaign replaces multiple separate tool runs.
AI-Assisted Reporting
DeltaSense platform delivers rapid, answer-first interpretation.
Job Planning
Configure sensor parameters, define intervals, and set objectives within the DeltaSense digital platform before mobilisation.
Job QC
Real-time quality control as data flows in. Validate measurements and flag anomalies before leaving the wellsite.
Job Answers
AI-assisted interpretation transforms raw data into decisions. Clear, actionable answers about annular integrity and well system health.
