A new miniature pressure/temperature sensor comes packaged inside a tough small ball capable of traveling to the bottom of a well while drilling and returning with data on board.

Our industry’s demonstrated ability to innovate and continually improve well-construction technology will be all the more valuable to all plays if low oil prices persist, but especially so for shale and other high-cost-per-barrel plays.

This study examines the effects of drilling, completion, and production operations and their associated cyclic stresses on a cement sheath.

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

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.
