In most petroleum companies, each element of the petroleum system is addressed through peer reviews and risking sessions. These elements are: source presence and its characteristics, source maturity, migration (carrier beds), reservoir, trap and seal. An additional risk is oil quality or its preservation. More than half of the risk associated with a prospect or play fairway is assessed via petroleum geochemistry and burial history / thermal / fluid-flow basin modeling.
This article will present how regional data, paleo-reconstructions, seepage data via piston coring and 2-D burial history / thermal / fluid-flow basin modeling have typed source-rock characteristics across the deepwater and ultra-deepwater Gulf of Mexico (GOM), and how this helps constrain source type and presence. Also discussed are new definitions of seepage related to petroleum systems vs. unrelated anomalies, how this helps constrain charge, and how all of these data were integrated to define a source-rock model for the deepwater to ultra-deepwater GOM.
Cooperative effort allows efficient, fast-track development of a gas field – The operator, gas marketer and equipment supplier brought a gas field to full production by using ready-to-ship packages and other equipment from inventory
State oil company Pemex will conduct a large-scale development of gas reserves over the next five years, much of it in the Northern Region’s Burgos basin
Part 2 continues the discussion of a new classification scheme for the world’s giant fields, focusing on the North Sea, Africa, Persian Gulf and FSU regions
In an exclusive interview, Turkmen Oil and Gas Industry Minister Kurbannazar Nazarov assesses the country’s energy sector and prospects for foreign investors
As some operators report production increases, further field tests are warranted for an emerging technology that improves EOR through seismic stimulation
While ignoring unreliable IEA figures, frequent shifts in OPEC quotas still focus too much on API stock changes, often resulting in unintended, wild price swings

In Brazil’s third bidding round, Phillips Petroleum Co. finalized an agreement on Blocks BM-ES-11 (in the northern portion of the Greater Campos basin) and BM-PAMA-3 (in the Para Maranhao basin, part of the southern Amazon Fan. Phillips will operate the deepwater blocks. Plans call for seismic acquisition and geological and geophysical evaluations.
