Production

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 ‘black box’ algorithms and software solutions. Nevertheless, failing to address…

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 and shape of blocks, in combination with the nature of…

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 of a reservoir’s performance and enable better decisions to be…

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 from resource plays (those in which the source rock and…

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 distribution in carbonate reservoirs in relation to their tight limestone…

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 Managing the Future

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 Asia-Pacific, are experiencing declines in hydrocarbon production with fields maturing…

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 understand the rocks that are the building blocks of energy…

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 the western flank of the Viking Graben in the Norwegian…

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 of technological advancements and improvements. The days of interpreting on…

Reservoir Modelling in 3D

People see the world in different ways. Some people have red/green colour-blindness; some people have acute myopia; nearly all people have some form of astigmatism; some people have synaesthesia; some people cannot see at all; some people choose not to…
