Most marine 3D seismic surveys are acquired with infill to ensure adequate subsurface coverage, especially in areas where seismic surveys are affected by adverse currents or suboptimal streamer feather angle matching.
In structurally complex areas, seismic interpretation can be misled by well data wrongly interpreted. A common approach in the oil industry privileges well data in a seismic interpretation.
Modern offshore site investigation techniques provide data sets that enable geoscientists to combine their geophysical and geological expertise to accurately identify and characterize geohazards, both at the seafloor and over the formation depths, which will influence design decisions within the development process.
Petrobras has designated a team to build its Master Plan for Santos Basin’s Pre-Salt Cluster Development, also known as PLANSAL, a guide to the exploration and production of oil and gas of this new frontier. At this point, Petrobras is increasing the managerial focus in all technical expertise, as well as encouraging tight integration and teamwork among all people involved.
Often, what is first considered a frustrating obstacle is later recognized as having an important function. So it has been with thick subsurface layers of salt. Long dreaded by explorers and drillers as hazards, salt formations are nonetheless very effective traps for oil and gas.
With an estimated 35 rigs idled in the Gulf of Mexico (GOM), Brazil is already receiving inquiries from companies looking to move their rigs here, where vast discoveries in recent years may soon turn the country into a major crude exporter.
Mission-critical processes now rely heavily on automated and highly integrated control systems software. This increased reliance on automation introduces invisible, but very real, software risks during the building, operation and refurbishment of high-specification offshore assets.
Polycrystalline diamond compact (PDC) cutters and bits have been a significant contributor to the greatly improved efficiencies and economics of oil and gas drilling over the last 30 years.
Raise your hand if you ever rolled your eyes when Grandpa Mort began a conversation with “back in my day.” Thought so. You’re certainly not alone, as most of us tend to dismiss offhand any historical footnote.
I don’t have a crystal ball to gaze into the future. But I attended the 14th Annual Gulf of Mexico Deepwater Technical Symposium on Aug. 19 in New Orleans, and I think I have seen the industry come to terms with the Deepwater Horizon incident and scope out a new scenario for safe deepwater drilling in the Gulf of Mexico.
There is no question Matt Simmons was a man of many words, words spoken with both conviction and fervor. Likened to the curious main character of Rudyard Kipling’s The Elephant’s Child, Simmons, who passed away on Aug. 8 at the age of 67, leaves behind a legacy of asking questions and making his actions speak louder than his words.
Four British oil companies continue to drill offshore the Falkland Islands and are now scheduled to drill eight new wells before the year is out, despite an escalating war of words between Argentina and the UK over the self-governing British territory. The companies currently involved are all small explorers, either privately owned or listed on London’s junior AIM market.
In an earlier column (“The age of migration,” July 2010) we discussed the history of seismic migration. Here we consider a related question: “What are the different kinds of migration, and which one should I choose?”
The untimely passing of Matt Simmons last month brought an end to one of the most original and controversial energy “insiders” (see “Innovative thinkers,” p. 21). Simmons, a regular contributor to this magazine since the early 1990s, did not coin the term “peak oil”—that distinction goes to visionary geologist M. King Hubbert—but he brought the expression back into the journalistic mainstream.
