carbonates

This paper presents a comprehensive analysis of autonomous scale-management strategies implemented in the Buzios Field that eliminate the need for a well-service stimulation vessel by using existing facilities onboard the well rig.

The creation of SPE’s Acid Stimulation Technical Section shines a light on the technique that improves injectivity and productivity. JPT talked with the chair of the new section about the importance of the technical area.

The Acid Stimulation Technical Section aims to provide a global home for engineers, scientists, researchers, and practitioners working on acid stimulation in carbonate and sandstone reservoirs.

Imaging carbonate rocks at high resolution without losing scale has long been a challenge. A novel framework is introduced that enables accurate super-resolution and extrapolation of carbonate rock images, enhancing micro-CT images while preserving mineralogical and topological features for more reliable pore-scale analysis and flow simulations.

This work applies fuzzy logic, a well-established artificial-intelligence technique, to quantitatively assess connectivity between injectors and producers in a giant presalt field in the Santos Basin of Brazil.

This paper presents a case study of a tool-free fishbone fracture stimulation technology using sand jetting and acidizing in openhole wells, providing a technical solution for low-permeability and complex-lithology carbonate reservoirs in the Middle East.

This paper reviews existing literature, the operator’s records, service-company data, and simulation studies to assess the risk of using seawater in carbonate acidizing.

The paper describes a project in which extremely challenging stimulations were performed in a fractured tight carbonate in a complex strike/slip stress faulting regime with high tectonic stresses.

Hydraulic fracturing holds great potential in the region, but there are several key questions worth asking as efforts move forward.

The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.
