Colorado’s Rangely oil field, with over 900 MMb of oil produced, has been viable and economic for more than seven decades thanks to an innovative and flexible approach.

Determining the source of hydrogen sulphide on an offshore oil production platform is an important part of preventing or controlling this unwanted gas.

Water occurs virtually everywhere in oil and gas fields – yet it is often ignored. But the composition of today´s formation water is the result of multiple hydrogeochemical processes, and a primary source of valuable information.

Back in the late eighties our ambition was to put modeling capabilities on every geoscientist’s desk. Now in 2015 that aim has been achieved, but are we actually producing the right models?

New developments in history matching improve uncertainty quantification and risk assessment in reservoir management.

The Principle of Uniformitarianism gives confidence in selecting well sites through looking at Holocene facies analogues.

From microscopic core analysis of the wellbore to seismic data measurements of rock properties between wells, a multidisciplinary team is essential when solving exploration and production problems in complex reservoirs.

Reservoir characterisation can be improved through the integrated analysis of CSEM, seismic and well log data.

The giant Kirkuk field, discovered in 1927, has had a very chequered history and requires imaginative reservoir engineering methods to return it to optimum productivity.

New developments in history matching improve uncertainty quantification and risk assessment in reservoir management.

Real time frac monitoring shows the progression of fractures opened during the fracking process, knowledge which can impact drilling decisions.

Following a rock properties-based workflow for shale plays makes it possible to gather intelligence which not only defines where to drill and how to frac, but also better predicts the economic outcome.

Why do time-lapse (4D) seismic surveys of producing reservoirs ‘work’ and why do we make observations from them that appear to be related to production?

Geological Expression utilises sophisticated technology to deliver dramatic gains in productivity through a workflow whose structure will be familiar to seismic interpreters.

Oilfield services company Baker Hughes has introduced a next generation geological facies module into its JewelSuite™ reservoir modelling product.
