With high oil prices as the incentive, deepwater operators are increasing worldwide activity and launching innovative floating structures for drilling and production. In the post-Macondo world, they must also meet the challenges of stringent safety and spill containment rules.
A six-well workover campaign at Hassi Messaoud field in Algeria used shallow-angle casing exit technology in conjunction with solid expandable liner systems to optimize a workover campaign and revitalize an aging field.
Around the world, shale assessments are underway in an attempt to emulate the success of shale gas and liquids production in North America. The U.S. Energy Information Administration (EIA) issued a report in April 2011 that discusses 48 shale gas basins in 32 countries (not including the U.S.), which contain about 70 shale gas formations. Initial estimates of technically recoverable shale gas resources in these countries examined is 5,760 Tcf.
A new screen technology that compartmentalizes sand ingress is the product of a joint development project aimed at improving sand control reliability without interrupting production.
North American Outlook
Political and pipelining concerns are clouding the picture for an E&P sector that has been riding oil activity to prosperity.
Weakness in crude oil prices, coupled with uncertainty about the presidential election and future economic performance, has caused U.S. drilling to go sideways. A trend was already present at the beginning of this year, whereby operators were steering large amounts of capital spending away from dry gas drilling. This factor has now been exacerbated by such a shift toward oil and NGL-directed drilling, that it has boosted liquids production fast enough to depress liquids prices in the short term,

Magda Chambriad, general director of the Brazil Petroleum Agency (ANP), points to the pre-salt clusters of the deepwater Santos, Campos and Espírito Santo basins to explain the terrifically bullish prospects for the nation’s E&P sector.
Despite the relative simplicity of Santos basin geology, experience shows that seismic imaging of pre-salt plays can be improved considerably when two-way wave equation with Reverse Time Migration is employed in the model building phase.
In a first-ever test, new-generation RSS and MWD technologies achieved a maximum DLS of 3.95°/30 m with only 81% of the RSS steer force in the 17½-in. section. The trials also validated the advanced RSS’s capacity to kick-off successfully from near-vertical in salt.
Lula field reservoir studies indicate that an EOR miscible method, CO2 and/or gas injection alternated with water, can improve ultimate recovery.
What’s new offshore Brazil. In March 2012, global travel management company Wings Travel Management, which specializes in oil and gas, corporate and marine travel, entered the Brazilian market throughout the acquisition of V7 Viagens travel-management company.
