This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.
Equinor and its partners’ investment in the Troll West Increased Gas Recovery North (TWIN) project aims to unlock around 11 Bcm of additional natural gas from the Troll field, with first production targeted as early as 2028.
In the fourth development phase, a planned tieback would connect resources from two North Sea discoveries to existing infrastructure at the Johan Sverdrup field, pending project sanction.

After 70 years of production, more than 30% of the Arab C reservoir stock-tank original oil in place has been recovered through various mechanisms including natural depletion, waterflooding, gas lift implementation, and horizontal-well development. -
This paper describes the first job in southeast Asia in developing horizontal-well placement in a turbidite environment.

This paper discusses the successful, fully integrated, 3D Earth modeling (EM) and dynamic reservoir simulation of the Hollin Formation in the Lago Agrio Field within an operator’s first producer field in Ecuador.

An auction of small discoveries that were passed over by India’s national oil companies is a test of the country’s efforts to boost oil and gas development by encouraging participation from inside and outside this energy-hungry country.
-
Successful rejuvenation of two declining fields was enabled through innovation in both engineering and procurement strategy.
-
A number of companies are pushing for alternative approaches to offshore development that seek to access marginal reservoirs. Their differing and unique ideas call for a departure from the usual playbook, but share a common goal of slashing capital costs.

Young Technology Showcase—Top-Down Modeling: A Shift in Building Full-Field Models for Mature FieldsData-driven, or top-down, modeling uses machine learning and data mining to develop reservoir models based on measurements, rather than solutions of governing equations.
-
A closer look at the design and construction of Statoil’s subsea gas compression systems in the Åsgard and Gullfaks fields, the first of their kind in the oil and gas industry.
-
In maturing oil wells, oil production is often restricted as reservoir pressure depletes. Two case studies highlight the application of two-screw multiphase pump systems in to extend well life.

The Samarang oil field, offshore Sabah, Malaysia, is undergoing a redevelopment project with integrated operations. Several work flows were designed and deployed in order to achieve an early milestone of providing real-time well-performance monitoring, surveillance, and optimization.
