Reservoir Management

Can we get more comfortable with uncertainty?

Unfortunately, diligent and scientific handling of subsurface uncertainty is rarely undertaken. Hesitance to embrace uncertainty often derives from time, data and budget constraints, limited interdisciplinary understanding, accompanied by claims of…

Evaluating Fluid Drainage Dynamics in Resource Plays

In this article we discuss how fluid chemistry can be deployed to directly confirm or refine the assumptions made when optimising developments in hydrocarbon production from resource plays.

Who Owns the Oil?

The why and how of unitisation. Nature does not respect the licence boundaries drawn on a map by humans. Oil and gas accumulations straddling licence boundaries are common. The size…

Exploring Uncertainty in Subsurface Modelling and Forecasting

Ensemble-based modelling has been delivering value to the E&P industry for over ten years, causing a fundamental re-think of what exactly is needed to more accurately forecast the future behaviour…

Evaluating Fluid Drainage Dynamics in Resource Plays

In this article we discuss how fluid chemistry can be deployed to directly confirm or refine the assumptions made when optimising developments in hydrocarbon production from resource plays. Hydrocarbon production…

Dolomite-limestone alternations – from outcrop to 3D model

While rock climbers try to avoid the thin, porous and microfractured dolomites, geologists involved with reservoir characterization go to great length in order to give a detailed account of their…

Managing the future

History-matching of reservoir simulation models,meaning adjusting and optimising the simulation model based on observed production data, has been a complex and time consuming task for the industry for years. MEPO…

Mature Fields: Easing into Retirement or a Second Career?

How can oil and gas fields extend their productive lives and are there opportunities to repurpose our fields, our facilities and ourselves? Many basins throughout the world, including those in…

What Can Multiscale 3D Imaging Do for Energy Geoscience?

Will examining rocks at multiple scales extend the productive lives of our fields and help to repurpose these assets, our facilities and ourselves? As energy geoscientists we continually strive to…

Broadband 4D Seismic Provides New Level of Detail in the Gullfaks Main Field

Understanding new details in the 4D seismic signal uncovered by a broadband time-lapse dataset at Gullfaks Main Field in the North Sea. The Gullfaks area is in Block 34/10 on…

Enhancing the Experience of Seismic Interpreters

State-of-the-art imaging and visualisation techniques that enhance the experience of seismic interpreters and reveal more geological information in the subsurface. The realm of seismic interpretation has now undergone several decades…

Reservoir Modelling in 3D

A geologist turned reservoir engineer makes a plea to fellow reservoir engineers to use all the tools at their disposal, including studying 3D visualisations to better understand hydrocarbon reservoir simulations.…
