Deepwater HP/HT Drilling-Fluid Development and Applications in the South China Sea
Researchers have developed a novel water-based-drilling-fluid system compatible with deepwater HP/HT wells in the Lingshui Block on the basis of a conventional drilling fluid and further optimization.
High-Performance Brine Viscosifiers for High Temperatures
A supramolecular viscosifier package has been developed that uses noncovalent associations between additives to enhance the thermal resilience of divalent brine fluids.
New Magnetite Nanoparticles Allow Smart Drilling Fluids With Superior Properties
The effects of adding iron oxide NPs on the rheological and filtration properties of aqueous bentonite suspensions have been studied by several researchers.
Drilling and Completion Fluids
Drilling in high-pressure/high-temperature conditions poses numerous challenges. Drilling fluid is subjected to extreme pressure and temperature, and its properties such as viscosity are affected strongly by pressure and temperature. Viscosity decreases with temperature and increases with pressure.
After Years of Development, Nanoparticle Drilling Fluid Ready
For nanotechnology-based drilling fluids, acceptance means proving they can outperform other drilling fluids. Initial results have been encouraging enough to move toward commercialization.
Drilling and Completion Fluids
With shrinking budgets and limited resources, partnerships and collaboration are considered the best options. It is no secret that universities and industry have a special platform to work hand-in-hand.
Method for Monitoring Mud Contamination in Wireline-Formation-Tester Sampling
The wireline formation tester (WFT) is a well-developed technology used to collect representative downhole fluid samples. The authors introduce a simple but effective method for monitoring WFT sampling when targeting the low levels of contamination needed for asphaltene-onset-pressure analysis.
Development of Novel Drilling-Fluid Nanoparticles for Enhanced Drilling Operations
This work focuses on the laboratory techniques for developing, assessing, and analyzing innovative water-based drilling fluids containing iron oxide (Fe2O3) and silica (SiO2) nanoparticles.
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.
Drilling Fluid Uses Acid and Salt To Improve Well Performance
The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.
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.
Case Study Shows Benefits of Applying Hollow Glass Spheres to Drilling Fluids
In an effort to optimize drilling operations and economics, an operator examined the effect of adding hollow glass spheres (HGSs) directly to the drilling fluid instead of performing underbalanced drilling.
Wellbore Strengthening in Shales With Nanoparticle-Based Drilling Fluids
This paper presents experimental research in which a significant fracture-pressure increase was achieved in shale and the predominant wellbore strenghtening mechanism was identified.
