Puzzling Salt Structures
Detailed salt modeling has unraveled the development of a mystifying collection of structures that are a key element in the eastern Gulf of Mexico petroleum system. Seismic mapping near recent…
Petrophysics in High Angle and Horizontal Wells
The benefits of directional drilling are widely known – increased reservoir exposure and greater production. However, the practice can pose formation evaluation challenges in high angle and horizontal wells, making…
Reducing Risk in Offshore Planning and Development
Ultrahigh resolution 3D seismic methods not only bridge the gap in continuity between the shallow subsurface and seafloor, but also the gap in communication between geoscientists and engineers. Responsible development…
A new member of the family
Samples of oil from the Gohta discovery on the Loppa High points to a Paleozoic source rock, a new member of the Barents Sea oil family, Lundin says.
New Perspectives on the Barents Sea
The recent opening of the south-east Barents Sea to oil and gas exploration has provided an opportunity to deploy the latest technologies such as full tensor gravity gradiometry to improve…
A New Approach to Cores
Digital archiving of core information affords the oil and gas industry an opportunity for rapid evaluation of core. The keys to the efficacy and value of cores in the oil…
Broadband Seismic Technology and Beyond PART XI: Which Technology to Choose?
Using the Utsira High as a field laboratory for broadband testing. The answer, my friend, is hiding in the waves, the answer is hiding in the waves (with apologies to Bob Dylan, and thanks to…
New Play Model revisited
Exceptionally shallow reservoirs surrounding the Hoop Fault System were among the most enigmatic areas being offered for the 23rd Concession Round.
Simplifying Digital Rock Physics Workflows
3D imaging of rock samples combined with intuitive software enables the comprehensive analysis of rock properties. Oil and gas researchers have a range of options available to them when analyzing…
Broadband Seismic Technology and Beyond PART X: IsoMetrix – Isometric Sampling
IsoMetrix is more than broadband seismic. It goes beyond, by reconstructing the deghosted wavefield in 3D, and performs fine spatial sampling in all directions. In this article we ask: how…
Exploration beneath Salt
The prospectivity of stratigraphically younger sediments beneath a salt layer has held oil and gas explorationists’ interest for years. The target of imaging technology has been to enhance the salt-sediment…
