Deep High-Pressure Completions: A Case History Offshore Gulf of Mexico
A Gulf of Mexico case history is presented describing the successful delivery of two deep high-pressure high-rate-designed oil wells in an ultradeepwater environment.
What Vacuum-Insulated Tubings and Casings Bring to Thermal Wells
This paper describes both design and economic considerations that lead to the selection of vacuum-insulated tubing (VIT) or vacuum-insulated casing (VIC) for the completion of thermal wells.
Integrated Approach for Overpressure Prediction in an HP/HT Well Offshore Malaysia
Pore-pressure prediction plays an important role in well planning as exploration targets shift to deeper, overpressured reservoirs.
Application of MPD Technology for HP/HT Wells in Vietnam
One common issue among operators in determining whether to install a managed-pressure-drilling (MPD) system for a campaign is the significant upfront cost.
First Expandable Liner-Hanger Installation in UAE in an HP/HT Well
This paper discusses the planning and deployment of an expandable-liner-hanger (ELH) system in an offshore high-pressure/high-temperature (HP/HT) well for the first time in the United Arab Emirates (UAE).
Instead of selecting papers that were dedicated to material selection, I considered works that concentrated upon best practices and recently developed technologies that make operations in these difficult environments more efficient and far safer for crews and for the environment itself.
Case History: High-Pressure/High-Temperature Underbalanced Drillstem Testing
This paper describes the method developed to achieve underbalanced drillstem testing (DST) in a deepwater field offshore India.
Optimal Nanosilica Concentration in Synthetic-Based Mud for HP/HT Wells
At certain conditions, the good performance of synthetic-based mud (SBM) will degrade, particularly because of the effect of chemical instability under high temperature. Silicon dioxide (SiO2) nanopowder (nanosilica) holds the potential for performance improvement.
Use of Life-Cycle Drilling-Simulation System on Challenging HP/HT Drilling Operation
This paper presents the LCDSS and elaborates on the use of it in the preparation and training phase and the operational phase, including forecasting.
New Deepwater, High-Pressure GOM Tubular Maximizes Capability, Reduces Cost
A 2-year comprehensive effort to design, test, manufacture, and deploy a new high-pressure completion tubular for Chevron’s deepwater Gulf of Mexico (GOM) operations is presented.
The engineering, design, qualification, and implementation of drilling, completion, production, and intervention equipment for high-pressure/high-temperature (HP/HT) developments present significant challenges.
Next-Generation HP/HT Subsea-Wellhead-System-Design Challenges and Opportunities
Moving to higher-capacity wellhead systems for high-pressure and high-temperature (HP/HT) environments will require a larger mandrel and conductor-casing size.
