The combination of ultrasonic pulse-echo and flexural-attenuation measurements was adopted in this project in the South China Sea for cement-integrity evaluation.

The first multilateral well in a North Kuwait field has been drilled recently.

Complex reservoirs in the Junín block of the Orinoco oil belt of eastern Venezuela offer challenges in achieving higher production rates and maximizing extraheavy-oil recovery.

Expectations of continued USD 100/bbl of oil were shattered by a sharp price drop last year that eventually halved the prices of benchmark crudes. Prices were still sinking at the start of the year to lows not seen since 2009 due to a global oversupply of oil.

The Burgan reservoir consists of vertically stacked channel sands along with a fault network connected to the aquifer and contains highly viscous reservoir fluid.

The paper discusses two gas/condensate-development projects offshore Vietnam that deploy managed-pressure-drilling (MPD) technology.

It is clear the oil and gas industry recognizes the large uncertainty in which it operates. A search in the OnePetro technical paper database using the keywords “uncertainty” or “risk” returns more than 53,000 conference and journal papers.

As is often said, all of the easy reserves already have been produced. Long gone are the days when low-risk, low-cost wells were drilled, completed, and put on production for a quick payout.

One approach to refracturing involves the use of mechanical diverters such as perforation balls and rock salts, which may be useful for one stage; however, cessation of pumping operations results in these diverters falling out of the perforations or dissolving.

Saudi Aramco’s upstream strategy aims to implement the intelligent field concept in all of its upstream operations by 2016–2017 so it can better understand reservoirs and improve efficiency.
