Every Sample Traceable. Every Certificate Defensible.
From wellsite to terminal, oil and gas laboratory data underpins production decisions, commercial settlements, and regulatory compliance. LIMSera provides the sample logistics, analytical workflows, and custody transfer documentation infrastructure to keep operations running — and regulators satisfied.
When Wellsite And Laboratory Data Don't Connect, Production Chemistry And Commercial Decisions Both Suffer.
Oil and gas operations generate samples from remote wellsites, offshore platforms, subsea manifolds, pipeline pig receivers, and refinery process units — often hundreds or thousands of kilometres apart. Managing the chain of custody from these diverse collection points through specialist analysis and back to production decision-makers is inherently complex. Breakdowns in sample integrity, custody transfer records, or analytical data routing can have commercial and regulatory consequences that dwarf the cost of the analytical work.
Production chemistry decisions — corrosion inhibitor dosing rates, scale inhibitor programs, produced water treatment, reservoir souring mitigation — depend on timely, reliable analytical data. When produced water results are delivered days late or with gaps in the chemistry profile, treatment decisions are made on incomplete information. Scale and corrosion events that could have been predicted from chemistry trends instead result in unexpected well interventions and pipeline integrity failures.
LIMSera connects wellsite sample logistics to laboratory analytical workflows and production operations in a single platform — so custody transfer certificates are generated without manual compilation, production chemistry alerts reach field teams in real time, and every regulatory compliance report is assembled automatically from validated data.
Every Testing Domain Across Your Oil And Gas Value Chain
Pre-configured for upstream E&P, midstream pipeline, downstream refining, and environmental compliance monitoring.
Upstream E&P
Support exploration and production laboratory workflows covering wellsite fluid sampling, reservoir characterisation, formation water analysis, drilling fluid testing, and produced water quality. LIMSera manages PVT analysis data, gas chromatography results for compositional analysis, H2S and CO2 content, wax appearance temperature, and corrosion inhibitor residual testing. Wellsite sample registration with GPS co-ordinates ensures spatial traceability from wellhead to laboratory. Real-time reservoir monitoring data feeds are integrated with production surveillance systems.
The Oil & Gas Sample Workflow, End To End
Wellsite Sampling
Samples are registered at wellsite with GPS co-ordinates, wellhead identifier, sampling time, and collection method. Preservation requirements and temperature constraints are applied automatically based on sample type. Chain of custody is established at point of collection with digital seal records.
Receipt & Condition Check
Samples arrive at the laboratory and are registered against the field sample record. Seal integrity, temperature compliance, and headspace condition are verified and recorded. Non-conforming samples are quarantined with field notification for re-collection decisions.
Analysis
Tests are executed following linked API, ASTM, IP, or IP methods with guided instrument interfaces. GC compositional analysis, PVT measurement, water chemistry, corrosion analysis, and environmental parameters are captured electronically with automatic data validation against method repeatability limits.
QC Check
Results are validated against quality control criteria — blank contamination, reference standard recovery, and duplicate precision. Out-of-trend results relative to historical well data are flagged for technical review. Regulatory limit exceedances trigger immediate alert notifications.
Technical Review
Results are reviewed with production history and reservoir context. Anomalous values are evaluated against geological and production data. Custody transfer results require second-person verification with inspector witness records. Electronic signatures applied with timestamp attribution.
Custody Certificate
Custody transfer certificates are generated with API/ASTM volume and quality calculations applied. Quality reports and environmental compliance certificates are delivered simultaneously to field operations, commercial teams, regulatory bodies, and customer portals.

Reservoir Health Visible From The Laboratory. Treatment Decisions Made On Data.
Produced water quality is a leading indicator of reservoir health, scale risk, and corrosion potential. LIMSera aggregates produced water chemistry data across all producing wells into real-time dashboards — tracking ion trends, TDS evolution, and scaling saturation indices that predict when calcium carbonate, barium sulphate, or iron sulphide deposition will begin. Production chemists see treatment performance linked directly to the analytical data that measures it.
Corrosion inhibitor residual analysis is trended against pipeline corrosion rate data from coupons and probes. When inhibitor residuals fall below minimum effective concentrations, or when coupon weight loss rates exceed threshold values, the system alerts the integrity team automatically. Chemical treatment optimisation — the balance between inhibitor cost and corrosion risk — is informed by real analytical data rather than routine treatment schedules.
Sample Integrity Protected From Wellhead To Report. No Chain-of-Custody Gaps.
Oil and gas samples are inherently difficult to manage. They are collected at remote wellsites under challenging conditions, transported over long distances with specific preservation requirements, and used to make commercial decisions worth millions. LIMSera's wellsite sample module manages the complete journey — GPS-tagged registration at the wellhead, digital preservation checklists, transport temperature monitoring, and laboratory receipt verification.
At every custody transfer point, a digital handover record is created with the identity of the person transferring, the identity of the person receiving, seal integrity confirmation, and temperature compliance verification. Non-conforming samples — broken seals, temperature exceedances, insufficient headspace — are quarantined immediately with field notification. The complete chain is preserved as a legally defensible digital record.
Regulatory Reports That Generate Themselves. Exceedances That Never Slip Through.
Oil and gas operations face complex, multi-regulator environmental monitoring obligations — OISD for safety, CPCB/MoEF for onshore environmental compliance, and MARPOL/OSPAR for offshore discharge monitoring. LIMSera maps every monitoring point to its regulatory permit conditions and monitoring frequency. Sampling schedules are generated automatically, and compliance reports are assembled from approved analytical data at the end of each reporting period without manual data compilation.
When an analytical result exceeds a permit limit — produced water oil content above the discharge consent threshold, stack emission above NAAQS limits, or groundwater monitoring showing contamination migration — the system triggers an immediate alert to the environmental officer. A nonconformance investigation is opened automatically with regulatory response timeline tracking. The complete investigation record, from exceedance detection through corrective action to regulatory submission, is maintained as a tamper-evident audit file.
