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.

After a year of field testing, a new type of biopolymer developed by Wintershall, Germany’s largest oil and gas producer, is showing promise as an effective enhanced oil recovery (EOR) tool in one of the country’s longest producing oil fields. -
Linhua4-1 was 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.
-
Onshore gas developments are often characterized by drilling, fracturing, and production of wells before low-pressure gas-gathering systems are in place. As well production declines, liquid-loading issues begin to appear. Use of a twin-screw pump to boost deliquefication was investigated.
-
This paper focuses on the applicability of subsea processing technology employing multiphase pumps to develop marginal fields commercially. Analytical methods were used to evaluate the pumps, and the results were validated through case studies in specific fields.
-
Sustainable growth in oil and gas production must stem from a combination of new discoveries and optimized recovery from maturing fields. Therefore, development of mature oil fields has been, and will increasingly be, an attractive subject.
-
The new channel-fracturing technique is capable of increasing fracture conductivity by up to two orders of magnitude.
-
As a field matures, there is a crucial need to focus on integrity-related issues such as hazard prevention and mitigation.

VICO Indonesia is the operator of the Sanga-Sanga production-sharing contract (PSC) in Indonesia.
-
In the southern North Sea, many fields suffer from declining gas production because of reservoir-pressure depletion and associated liquid loading.
-
A successful field trial in which foam was used as a gas-injection conformance enhancer was implemented in the Cusiana field in Colombia.
