Mature fields
The paper evaluates the effect of different injection methods on oil recovery and CO2 storage potential in a depleted sandstone reservoir in the Norwegian Continental Shelf.
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.

This case study describes how gas condensates within a subsea tieback system behave very differently to condensed water from a wet-gas system and therefore a pseudo dry-gas system needs to be configured differently for gas-condensate developments. -
Production data from the oldest horizontal wells in the three largest oil plays in the US show that annual decline rates remain relatively high for a long period of time. This challenges assumptions held about production after 5 years and directly affects reserve and ultimate recovery estimates.

The complete paper explores technical and economic development options to produce heavy-oil resources at commercial rates and showcases three optimization scenarios of higher recovery efficiency aimed at increasing net present value at the basin level.

Production decline with field maturing is a natural phenomenon, but the efforts to mitigate this decline are truly remarkable. Achieving this feat requires not only a deeper understanding of the subsurface process involved but also a total synergy between the various disciplines engaged.

The XamXung field offshore Sarawak, Malaysia, is a 47-year brownfield with thin remaining oil rims that have made field management challenging. The dynamic oil-rim movement has been a key subsurface uncertainty, particularly with the commencing of a redevelopment project.

To predict liquid-loading tendencies and to identify opportunities for production enhancement, the performance of 150 gas wells was analyzed in two gas fields in India.
-
This paper compares the performance of three mature-field horizontal infill wells, one of which is completed with autonomous inflow-control devices (AICDs).
-
This paper details the design and execution of what the authors say they believe is the first successful frac-pack operation in a previously gravel-packed well.
-
A case study in the deepwater Gulf of Mexico in which pressure transient analysis, fractional flow, and production logging tools were integrated to identify correctly the cause of, and execute an effective remedy for, a well’s productivity deterioration.

SponsoredMesser and Nissan Chemical recently introduced a new Huff ’n’ Puff process that combines CO2 or N2 gas and nanoparticles for synergistic multi-spectrum recovery enhancement from aging, depleted wells.
