Reservoir
The technology has passed its first phase of qualification, with 84 nodes placed on the seafloor at a depth of 2,000 m to acquire 4D seismic data in the pre-salt Santos Basin.
Chevron and Halliburton describe how they built and deployed the fully autonomous closed-loop fracturing system that enables subsurface-driven optimization.
This article from the SPE Integrated Reservoir Management Technical Section (IRMTS) addresses decision timing across the reservoir cycle.

This paper presents an integrated system for fracturing optimization using real-time and historical data along with organizational knowledge and the challenges and key considerations of implementing such a system. -
This paper describes the analysis of actual performance data for acid fracturing in a tight carbonate formation to investigate the ineffectiveness of the process.
-
The authors of this paper describe an underbalanced coiled-tubing drilling campaign in the operator’s onshore fields using a closed-loop system design.
-
This paper presents the interpretation of two polymer-injectivity tests performed in two giant light-oil high-salinity/high-temperature carbonate reservoirs onshore Abu Dhabi.
-
The authors describe a casing-leak-repair alternative to allow continued hydraulic fracturing of an unconventional formation.
-
The authors describe coiled tubing operations that used a riser on a monohulled vessel already performing riserless interventions.
-
The first acid job dates to 1895. Challenges remain, however, when it comes to lithology, coverage, penetration, and management of reaction products. These themes remain a focus for stimulation engineers.
-
The paper describes the development of an alkaline/surfactant/polymer formulation for the Mangala field in India, which involved more than 30 corefloods.
-
In this paper, a comparison is presented of the range of production outcomes for Clair Phase 1 and Clair Ridge, including the potential downsides of relying on natural fractures.
-
This paper presents a novel mathematical model for design and evaluation of fluoroboric acid treatments that takes into account the chemical kinetics and equilibrium aspects of important reactions and fluid flow inside the reservoir rock.
