capacity potential of 130 MW, the generators are not all running at a given time. The electricity generation capabilities have met the demands of the artificial lift (ESP) program, which has extended the life of the project. A new drilling campaign will begin in April 2015. The plan comprises seven new wells designed to slow the decline of the fields. Even so, production decline remains a serious problem. In the past decade, overall production has fallen from 65,000 BOPD to 34,000 BOPD. While Block 16 may not produce oil forever, the lessons learned here will be applied to the new discoveries in the Ishpingo, Tambococha, and Tiputini (ITT) regions. Also located in the Yasuni National Park, the ITT block was recently sanctioned and is thought to hold up to 850 million bbl of oil. If accurate, this would account for onefifth of Equator’s total oil production. The ITT development may be good news for the country’s economy, but to succeed, it will need to borrow learnings from its more modest neighbor in Block 16. OGF PFC ROUNDUP

Summary Severe slugging is a transient multiphase-flow phenomenon that can occur in pipeline-riser systems, particularly in offshore production of oil and gas. It is characterized by large pressure fluctuations at the base of the riser and is accompanied by fluctuations in fluid delivery from the top of the riser. This unstable phenomenon is undesirable because production and equipment are affected adversely by the large pressure and flow-rate fluctuations. In this study, air-/ water-flow experiments have been carried out at the S-shaped-riser facility in the multiphase-flow laboratory of the Norwegian University of Science and Technology (NTNU) and have been compared with results from a flow simulator (OLGA®). The results obtained in the work show that stability maps, pressure amplitudes, and slug frequencies are in acceptable agreement with each other; however, some deviations are seen regarding the slug frequencies at low flow rates.

In the 11th century, Raja Bhoj of Dhar founded a city on the shores of a beautiful lake in central India. Today, that city, Bhopal, is a bustling metropolis of 2 million people. The city and surrounding area is home to a large wildlife refuge, a museum of Indian tribal life, a collection of historical palaces and temples, and Stone Age cave paintings. Almost anywhere else in the world, this city would be a major tourist attraction, but Bhopal is wellknown for something else: It is the site of the deadliest industrial accident in history.

Summary Liuhua4-1 (LH4-1) oil field is located 215 km southeast of Hong Kong in the South China Sea. The field was first discovered in 1987, but because of economic and technical challenges, it was not until 2012 that the development of this field became a reality. The 300-m-water-depth oil field was successfully tied back to an existing oil field [Liuhua11-1 (LH11-1)] through subsea pipeline, power cable, and multiplex control umbilical. The project executions included disconnection, life extension, and reconnection to the existing oilfield floating-production system (FPS). It was also China’s first tieback subsea development project. To develop this marginal oil field, a number of technical challenges were overcome through a series of new technologies, and their successful development and implementation.
