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.
The HP/HT Completion Landscape
This paper identifies current development paradigms and discusses the future challenges in well planning, product development, and regulation.
Managed-Pressure-Drilling Technology Delivers Challenging HP/HT Drilling Campaign
The Shearwater field is a deep, high-pressure/high-temperature (HP/HT) reservoir located in the UK Central Graben of the North Sea.
Filtrate and Mudcake Characterization: Implications for Formation-Damage Control
This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability.
Novel Drilling Fluids Enable Record High-Temperature Well Offshore Malaysia
Despite hostile wellbore conditions, an operations team overcame challenges of drilling-fluid design and management to drill the first ultrahigh-pressure/high-temperature (HP/HT), deep-gas well offshore Malay Peninsula.
