For more than 20 years, Belltree has supported upstream oil and gas portfolios by combining deep subsurface expertise with data-driven benchmarking and analytics.
Our experience spans field performance evaluation, reserves and uncertainty assessment, and long-term development planning across a wide range of global assets.
We help clients translate complex technical analysis into robust, defensible decisions, supporting portfolio optimisation, transactions and independent reporting where clarity and credibility ma
Strategic Portfolio Review. Involving a National and Global Assets benchmarking study, deploying bMark proven predictive analytics and global data insights, we will highlight recovery potential, underperforming assets and provide the route to attain that.
Evaluation of new acquisitions and assets value, providing an examination of geological metrics and recovery factor review.
Independent view on Reserves resources. We have been a trusted provider of expert reports globally.
Reduce risks and maximise returns. Our Field Development Planning services transforms the manual process of collating field development data to streamline the process, make it automatically auditable and provides a wide understanding of FID’s feasability. Improve Field Planning and operation optimisation with Belltree services and digital solutions. Support in subsurface flow assurance.
LTRO provides a unique field analysis technique based on fundamental reservoir management principles: Voidage, Volumetrics, and Mapping. The goal of LTRO is to focus on “developing the field” rather than “developing the model.”
Our team provides integrated geological and geophysical expertise to support subsurface evaluation, reservoir understanding, and informed decision-making throughout the asset lifecycle.
At Belltree, we combine deep subsurface expertise with the scale and consistency of bMark™, our proprietary benchmarking and production analytics platform, to deliver robust, decision-ready insight. By placing assets and prospects in the context of global analogue performance, we strengthen individual project analysis and provide a consistent basis for evaluating reserves and development metrics across portfolios.
This integrated approach gives clients greater confidence in forecasts, clearer visibility of risk and opportunity, and a defensible foundation for investment, transactions and reporting.
Belltree leverages the power of bMark™, our propietary solution, to underpin studies we undertake for oil and gas operators and regulators worldwide: National Benchmarking Analysis, Due Diligence and Data Room Support, Competent Person Report (CPR) & Expert Opinion and Integrated Well & Field Development Planning.
By embracing innovation we believe that we can help build a better upstream oil and gas sector which meets global energy requirements more efficiently and with higher returns to energy companies and societies.
That’s why we built bMark™ to help bring the data revolution to energy professionals by augmenting industry expertise, improving data governance, enhancing technical insights and reducing study costs.
bMark™ intuitive user interface allows independent assessments to be made in minutes… Some large Operators have had such tools at their disposal for several years. bMark™ now provides this critical capability to the Industry at large.
CCUS success begins with rigorous subsurface screening. Belltree provides a structured, data-driven evaluation framework to quantify storage capacity, assess injectivity and containment risk, and identify viable storage sites with confidence.

bMark™ global data and benchmarks were teamed with Belltree’s expertise in technical due diligence to support a corporate takeover of assets in Norway.
Background:
Belltree was the lead technical expertise provider integrated with a corporate due diligence team from an international name-brand firm. We represented a buyer considering a corporate takeover involving 39 assets offshore Norway. The seller’s mixed portfolio contained mature producing fields, discoveries under development and exploration prospects. All fields (including 20+ years of data for mature assets) were to be assessed in less than 5 weeks.
Project Highlights:
Belltree quality-checked the Seller’s technical assumptions using the bMark™ database, leveraging its high-density Norwegian field dataset alongside relevant international analogues. Belltree identified systematic “optimism” in the Seller’s predicting of recovery factor for yet-to-be-developed fields. Suitable discount factors were generated with bMark™ benchmarks and Seller production profiles downgraded for the fair market value calculation.

Overview, Client Challenge
The client was operator of a large tight oil field in Western Siberia which had been in production for over 15 years. Recovery from the field had been modest to date compared to the in-place volumes and the client planned a significant drilling program to boost reserves. To support this endeavor the client built a dynamic model of the field but was unable to achieve a history match. The client requested that Belltree review the field to understand why the modelling workflow was failing and to provide an independent viewpoint of field potential.
Solution by Belltree
Belltree reviewed the client’s current model and approach and quickly concluded that application of its LTRO workflow would be appropriate to uncover the reasons behind the failure to achieve a history match. The LTRO process was completed in six months and with the significant insights gained Belltree was able to take over development of the dynamic model from the client’s team and achieve a history match within 2 months.
Achievements
By taking a step back and considering the totality of information available for the field in a systematic manner the Belltree team were able to identify a major thief zone in the field that was not present in the client’s field model. The LTRO process also identified significant upside potential via a reorientation of the existing waterflood and via infill drilling targets. The project targets identified via LTRO were subsequently supported by the dynamic model developed by Belltree. This work was used to directly support the decision to conduct a horizontal well campaign which added significant reserves to the field.
