Improve Exploration Success by Maximizing Seismic Information

Challenge

How can I gain a better understanding of my prospect, find new reserves and identify drilling targets more quickly?

Solution

Superior integration of high-resolution visualization data, seismic volume interpretation and earth modeling from basin to reservoir scale can provide valuable insights into the hydrocarbon source, migration patterns, maturation and trapping. It can also enable a detailed characterization of the potential reservoir, enabling the successful exploration of reserves and identification of the best drilling targets.

In the deepwater basins of West Africa, advances in interactive volume interpretation and collaborative visualization permit greater insights into the exploration and production of hydrocarbons. Following the Mesozoic break-up of South America from Africa, rift basins, containing rich oil-source rocks were laid down along the Atlantic margin, overlaid by unstable salt deposits. These complex salt-body structures provide a major seismic processing and imaging challenge.

Halliburton uses advanced seismic, geologic, petrophysical and reservoir engineering analyses to scrutinize a prospect’s source, seal, trap, reservoir and production potential. Through pre-stack and post-stack data, petrophysical analysis and AVO analysis, we have created an efficient lithology and pore-fluid technique that can be directly tied to interpreted seismic volumes. It also enables us to successfully investigate potential drilling, completions and facilities scenarios.

Additionally, Halliburton’s seismic attribute-extraction and similarity-processing techniques help geoscientists unravel complex geologic settings. Inversion and waveform classification further reveal reservoir detail. Used together, this suite of post-stack and pre-stack seismic data-processing technology can help geoscientists extract more information and ultimately increase understanding of the subsurface to reduce project cycle time and improve interpretation accuracy.

This holistic approach improves understanding of geologic, engineering and broader economic risks, enabling drilling to begin with confidence. Greater understanding also enhances the ability to estimate reserves and determine investment potential, facilitating the exploitation of the best prospects – and maximizing  the value of decisions.

Halliburton's seismic volume-visualization and interpretation technology can scale from the desktop to the largest immersive environments. Our earth-modeling solution delivers an integrated software suite for constructing an accurate representation of reservoir or basin-scale assets. Its software supports the collaborative efforts of reservoir engineers, geophysicists and petroleum geologists to collectively model and more accurately assess reserve potential and predict reservoir performance.

In one case offshore Nigeria, Halliburton’s well-planning software enabled the development of directional wells that substantially reduced cycle time, eliminated data-transfer errors, improved quality control, increased the accuracy of final wellbore designs and enhanced teamwork among geoscientists and drilling engineers. This well-design process reduced cycle time from weeks to days, enabling 33 wells to be planned in just three days. In the process, it improved quality control and the accuracy of wellbore designs while significantly enhancing teamwork.
