Mature fields
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.
Production delivered by the subsea artificial lift system will equal that obtained by drilling two new wells, according to BP.

The authors describe a carbonate reservoir stimulation technique able to deploy acids in the rock far away from the wellbore through mechanically drilled holes with known depths and azimuths. -
The complete paper reviews the history of enhanced oil recovery and the Scurry Area Canyon Reef Operators Committee, discusses changes in theory over time, and provides a look at the field’s future.

In the complete paper, the authors present a novel approach that uses data-mining techniques on operations data of a complex mature oil field in the Gulf of Suez that is currently being waterflooded.
-
The complete paper describes the first implementation of a solution to control fracture height for conventional wells in the Pannonian Basin.
-
The complete paper describes the first successful implementation of natural dumpflooding offshore Malaysia as a case study to provide insight into the value of using the approach to maximize oil recovery in a mature field, particularly in a low-margin business climate.
-
In this year’s papers on mature fields and well revitalization, I have found operators focusing on making all-out efforts to improve their ongoing waterflood operations to extend the life of existing wells, which is preferred over drilling new infill wells.
-
The complete paper outlines some of the challenges involved in late-life field management and how Reserves assessment may be affected.
-
To have the flexibility to treat both rich and lean gas wells [up to 100% gas volume fraction (GVF)], a new multiphase pump system has been developed by comparing the different boosting systems performance and analyzing well-by-well production scenarios.
-
To further reduce backpressure on low-pressure gas wells and increase reserves in a mature gas field, a gas-ejector project was evaluated and proposed.
-
The complete paper presents a solution that assesses tight matrices and natural fractures at a level not previously achieved. At the tight-matrix level, advanced nuclear spectroscopy is carried out with a new pulsed-neutron device that achieves simultaneous time- and energy-domain measurements.
