Marine Well Containment Corporation (MWCC) and Helix Well Containment Group have introduced an interim containment system, Helix Fast Response System, in February 2010, at the US Gulf of Mexico (GOM). The system, which is issued the first deepwater drilling permit by Bureau of Ocean Energy Management, Regulation, and Environment (BOEMRE), is built around a mix of new equipment and components used by BP last year to shut down the Macondo well. The unit with one blowout preventer was described as a dual barrier design able to control pressure and well flow up to 15,000 psi at two points in the assembly powered by a nearby manifold. The company is also searching for locations for staging equipment on the coast of Louisiana and Texas and a final decision is expected by mid-2011. Helix has involved regulators with regular briefings on its equipment development program, with an emphasis on incremental improvements in equipment already in use by the company, which specializes in deep-sea well work.

An estimate has found that Europe's total shale gas in place could be 6,115 Tcf and among the key challenges that will determine the ultimate productivity in Europe is a regulatory environment that is currently not suited to unconventional gas. 3Legs Resources holds six hydrocarbon exploration and prospection licenses in the Baltic covering a total area of approximately 1.03 million acres. ExxonMobil has built a large acreage position in the Podlasie and Lublin Basins of eastern Poland, the location of a potential new shale gas play. In the Ukraine, the Dnieper-Donets Basin is being targeted for shale gas potential. Canada's Realm Energy has announced plans to explore for oil and gas potential in the Posidonia and Weald shales. In northern Europe, Cuadrilla Resources and DSM Energie bought permits in the Netherlands, while BG also has a large exploration tract on the east Netherlands border with Germany.

The year 2010 saw an increased supply of sand-based proppants by either newly established or nontraditional frac sand suppliers, with several more operations pending. Oxane says that coating silica sand with resin has two principal functions such as improving the proppant's effective strength and spreading the pressure load more uniformly. Santrol Proppants, part of Fairmount Minerals, one of the largest producers of industrial sand in the US, announced the sizable expansion of its resin-coated proppant (RCP) facility in Roff, Oklahoma, scheduled for completion late 2011, with an increased annual capacity of 500,000 US tons. ARBO's Toomsboro, Georgia, facility includes brand-new line 3 just added 250 million lbs per year of proppant to the marketplace. Nittany Extraction Technologies Company (NETCo) use waste material, including glass, alumina silicate mine tailings, fly ash, and metallurgical slags, and rock cuttings produced to the surface during oil and gas drilling, in the manufacture of high-performance proppants.

A permanent downhole monitoring (PDM) survey conducted among SPE readership worldwide identified some of the main value propositions for PDM. The most important propositions found include optimizing production through continuous information, avoiding the necessity to shut in the well to obtain pressure ratings, and emerging distributed temperature capabilities that add further value in understanding and optimizing production. The growing importance of fiber optic technology and distributed temperature sensing was also raised by a number of operators. It was also identified that the technology providers have to be able to show that the value exceeds the costs. The survey found that significant improvement has been made in the reliability of gauges and other components of PDM systems. Logging while drilling (LWD) suffered a considerably slower uptake because the quality of the initial formation evaluation logs was inferior to those obtained via wireline.

A Brazilian national oil company, Petrobras, is aimed towards identifying and optimizing new deepwater presalt layers by dealing with the geological, engineering, commercial, and financial challenges. The company fulfills these aims by acquiring various deepwater and ultradeepwater presalt leases in the Santos Basin, acreage that in total is larger than the entire Campos Basin to the north. In 2006, Petrobras drilled the Parati prospect on block BM-S-10 to test objectives in the post-salt section and a dome structure in the presalt. The company made further discoveries in the Santos presalt during 2008 at Jupiter, Bem-Te-Vi, Guara, and Iara. Petrobras in 2007 initiated a major technology-development program, Prosal, To meet the multiple challenges of drilling and developing the complex, difficult, and physically remote presalt reservoirs.
