Who We Are

WellSoft AS

WellSoft has developed proprietary technology and methodology which enables us to deliver the optimised way to drill the well to achieve the best possible situation for reduced well bore damages.
The solution will give the best possible situation for increased production of Oil and gas and to maximise injection of CO₂.

Wellsoft AS

It will reduce infrastructure utilisation and reduce operational risks, leading to a more sustainable operation by minimising costs and, ultimately, reducing the carbon footprint.
The technology is a software solution and the methodology is based on a 9 step work flow process.

What We Do

Introduction

Formation damage during drilling is one of the most persistent challenges in well construction. Even under carefully designed conditions, solids invasion and fluid losses can reduce porosity and permeability in the near-wellbore zone, limiting well productivity. Traditional laboratory tests often struggle to capture these effects due to limited exposure time and sample size, which means the true severity of damage may be underestimated. At WellSoft, we address this challenge with our proprietary Well Damage Simulator (WDS) — an algorithm developed from years of scientific research and industry experience. WDS models particle transport, wallcake efficiency, and the impact on porosity and permeability, offering operators a clearer understanding of damage mechanisms and practical ways to mitigate them.

Our Roots

Founded in Norway in 2019 by Morten Lunde, Tommy Ness, and Stig Solberg, WellSoft began with a mission: to improve recovery from oil and gas fields by better understanding and limiting formation damage. Drawing on deep industry expertise, we identified the deposition of solid particles as a common yet underestimated cause of reduced productivity. That insight led to the development of WDS — a science-driven tool designed to quantify and minimize damage across the full drilling lifecycle.

Our Product Line

1. Pre-Drilling Simulation
Before drilling begins, WDS is calibrated using laboratory test data — including core flow experiments with reservoir samples and drilling fluids. These calibrations account for key mechanisms such as external and internal filtercake (the “wallcake”), spurt loss, and solids deposition in pore spaces. The result is a reliable prediction of how drilling fluids may alter near-wellbore porosity and permeability.

Establishes Reference Values (RVs) for BHP, density, rheology (PV & YP), and solids content.
Improves planning accuracy by simulating drilling schedules and identifying safe operational windows.
Equips operators with a clear baseline for damage mitigation.

2. Real-Time Monitoring
During drilling, WDS becomes a live monitoring tool. Data from non-intrusive clamp-on sensors and handheld XRF gun results are continuously processed against Reference Values. The WDS engine predicts near-wellbore damage in real time, ensuring that deviations are detected early.

Tracks changes in critical drilling parameters.
Generates traffic-light alerts (green/yellow/red) supported by context-specific mitigation suggestions.
Provides damage vs. depth visualizations, linking drilling progress to evolving near-wellbore conditions.
Protects reservoir productivity by allowing timely operational adjustments.

3. Post-Drilling Evaluation
After drilling, WDS delivers a structured evaluation by comparing Reference Values, drilling reports, and mud reports with actual performance. This post-operation analysis quantifies how much formation damage was avoided or occurred, and where further improvements are possible.

Validates the effectiveness of drilling practices.
Supports Quality Improvement Processes through evidence-based feedback.
Strengthens planning for future wells.

Technical Discussion

Drilling formation damage due to solid particles deposition can generally be separated into three regions:

External filtercake
Internal filtercake
Invaded zone

Figure 2. Schematic view of the drilling fluid and particle deposition area.

The external and internal filter cake is generally referred to as “wallcake” which functions as a planned barrier to reduce drilling fluid and solid particles from entering the formation. The efficiency of this barrier is a key consideration when modelling the transport of solid particles into the formation.

The WellSoft model is dependent on the determination of the barrier efficiency to accurately estimate the deposition of the solid particles penetrating deeper into the formation. For example, “spurt loss” is a zero efficiency wallcake since the wallcake has not yet formed resulting in some fraction of the drilling fluid and solid particles to penetrate the formation in a relatively short time span depending upon the characteristics of the drilling fluid and formation. Other examples of reduced wallcake efficiency could be due to erosion, mechanical removal or continuous wallcake leakage resulting in the loss of drilling fluid and solid particles into the formation over longer time spans. To this end, WellSoft can work with your drilling fluid and laboratory providers to determine wallcake efficiency during different conditions to ensure our model provides the best possible solution to describe the transport of solid particles and the resultant reduction in productivity. Final productivity reduction is then determined based on the external filter cake being fully removed so that the only remaining damage reported is in the formation.

The following are the general physical processes used to model the reduction on productivity:

Flow of the drilling fluid, solid particles and the formation fluid in the porous rock
Displacement of the formation fluid by the invading drilling fluid (interface advancement)
Deposition of solids from the drilling fluid at the borehole wall and in the pore space
Change in the porosity in the invaded zone due to the deposited solid particles
Change in the permeability in the invaded zone due to the change in the porosity

The following is a general illustration of the model process.

Conclusion

From simulation before drilling to real-time surveillance during operations and evaluation after completion, WellSoft’s Well Damage Simulator (WDS) provides a unified, science-based approach to managing formation damage. By combining rigorous modeling, real-time data, and post-drilling insights, we help our clients drill smarter, protect reservoir productivity, and continuously improve well delivery outcomes.

Our Story

About Us

In 2019, WellSoft was founded and incorporated under Norwegian law by Morten Lunde, Tommy Ness and Stig Solberg.

Their insight and expertise in the O&G industry identified opportunities to improve recovery from oil and gas fields. WellSoft devoted time and effort to investigate opportunities connected to near-wellbore damages caused by drilling and completion operations.

Global reports indicate that oil recovery differs greatly even between reservoirs that have a lot of commonalities from geological and geotechnical points of view. The average global recovery is about 26-28%, while recovery from other areas is substantially higher i.e. 50-55%.

WellSoft developed a software tool that produces input for an optimised drilling program that helps recovery from each well.

Maximizing Efficiency

One of the main reasons for reduced recovery is the near-wellbore damages from drilling and completion.

Based on the industry experience and scientific research, WellSoft developed an algorithm that suggests how a combination of several drilling inputs, such as the choice of fluids and pressure, helps reduce well damage.

WellSoft’s nine-step workflow process and unique algorithm solution offer a greener footprint for the operators. Current industry practices to increase well recovery, such as well / acid simulation, increase the risks of contamination and carbon emissions.

WellSoft has, together with the Norwegian University of Science and Technology (NTNU) and SINTEF, developed the Wellbore Damage Simulator (WDS) to simulate the input for optimised drilling program for each well.

The world need to take more responsibility for the environmental changes. As a part of this CO₂ capture and storing (CCS) is one of the most important activities. Our solution will ensure that wells are better prepared to maximise the injection of liquid CO_{2 .}

WellSoft and a Canadian company Beyond Energy signed an Innovation Contract in May 2021, this contract was extended in an MOU for joint development on February 2022.
