Once labeled “undrillable,” Brazil’s heavy-oil Atlanta field in the Santos Basin faced technical, financial, and logistical challenges. But through a phased approach, clever reuse of assets, and disciplined project execution, Brava Energia transformed a risky deepwater asset into a producing field with 172 million BOE in 2P reserves. -
In the wake of the falling number of exploratory wells in the country, Brazil-owned Petrobras addressed audience concerns as well as outlined new avenues for production at the Offshore Technology Conference. -
New strides in computer vision, well controls indicators, and BOP alignment were showcased at the recent Offshore Technology Conference. -
Data mining techniques are unlocking new insights from the performance of thousands of Bakken wells. This article explores how those insights are helping refine completion optimization.
Guest Editorial
-
Best practices are not static; they evolve alongside advancements that redefine what is achievable.
Comments
-
The early enthusiasm for carbon capture and storage (CCS) is showing signs of strain as the limited capital availability and political support become clearer.

SPE Technical Paper Downloads
-
SPE technical papers synopsized in each monthly issue of JPT are available for download for SPE members for 2 months. These May and June papers are available now.
Coiled Tubing
-
Each of these papers presented at SPE conferences exemplifies engineering solutions to maximize commercial value while retaining focus on HSE and service quality.
Acidizing
-
This year’s Acidizing feature presents three SPE conference papers that discuss an important battlefront of enhanced production—carbonate reservoirs, those plays whose heterogeneity, reactivity, and flow behavior pose challenges that remain comparatively little-understood, despite the industry’s intensified efforts to maximize their output.
Hydraulic Fracturing
-
Modern completions often are equipped with downhole measurement devices that provide critical real-time data not only during the hydraulic fracturing treatment but also during the ensuing production phase.
EOR Operations
-
The three papers selected for this feature highlight some creative solutions that aim to increase project value by either increasing recovery or optimizing injectant cost, or both.
