Better well test data.
Clearer reservoir answers.
Oil and gas specialists supporting operators from exploration and appraisal through production. We design tests that meet your subsurface objectives with less rig time and less flaring — then interpret the data to extract every insight it holds.
Services
Well test support across the life of the field
Act as your team’s analysis expert, or be the second pair of eyes on your data. We can also re-analyse old tests and challenge previous interpretations.
01
Exploration & Appraisal
Test design covering the full range of uncertainty, real-time QC and interpretation during operations, and post-test analysis with deconvolution to prove connected volumes.
02
Production & Injection
PBU and PFO analysis to track well and reservoir performance, protect base production, explain performance deviations and assess well interventions.
03
Frac Evaluation
DFIT, ACA, SRT and minifrac interpretation plus post-frac analysis. On injectors, monitoring fracture growth to protect cap-rock integrity.
04
Training & Coaching
Practical courses in well test design and pressure transient analysis for engineers, geologists and petrophysicists — in-house or online.
How we work
From test design to reservoir insight
Step 1
Design
Define objectives, durations and gauges so the test answers the subsurface questions — at minimum rig time and flared volume.
Step 2
Monitor
Real-time data QC and live interpretation to optimise operations and catch value-adding opportunities as they appear.
Step 3
Interpret
Explore every plausible solution, recover deconvolution and quantify permeability, skin, boundaries and connected volume.
Step 4
Integrate
Review with your subsurface team and tie results to geology, logs, core and simulation for decisions you can stand behind.
Software
Tools built by practitioners
Technology we co-founded to make well test and reservoir analysis faster and more robust.
ConvEx
Production dynamic analysis, interference studies with multi-well deconvolution, and matching of data with more complex reservoir models using a semi-analytical reservoir simulator.
PIE-Web
Cloud-native, automated and AI-assisted. The proven algorithmic depth of PIE — the industry’s most rigorous PTA software — in an intuitive web application that removes barriers to access, standardises workflows and unlocks data-driven automation.
PIE Desktop
The proven PIE pressure transient analysis software, known for rigorous well test interpretation. The software has been enhanced by experts at TOTAL and BP over the past 30 years, with the most reliable deconvolution and analytical models on the market.
