Mature fields
This study leverages oil-fingerprinting technology and geochemical data to evaluate the fluid connectivity between a main field and its stepout wells.
The investment underscores ExxonMobil’s pivot to Nigeria’s offshore after it finalized the divestiture of its onshore assets in the country.
The contracts build on Cairo’s decades-long strategic energy alliance with Moscow, which will soon include nuclear energy.

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.

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 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.
-
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.
-
The surge in unconventional completions over the last decade has created ample candidates for hydraulic refracturing, which has been demonstrated to be a viable alternative to the more expensive endeavor of drilling and completing new wells.
-
The surge in unconventional completions has created a substantial accumulation of previously hydraulically fractured wells that are candidates for hydraulic refracturing.
-
A matured field is currently producing with greater than 85% water cut (WC) and has significant levels of uncertainty with respect to oil/water contact (OWC), flank structure, depth of spill points, production allocation, and residual oil saturation.
