Improving Thermal Stability of Starch in Formate Fluids for Drilling High Temperature Shales
Starch is one of the most widely used biopolymers in water based drilling fluids to control fluid loss. The thermal stability of starch in common drilling fluids is low (93 °C). In this study, the thermal stability of starch has been evaluated in sodium/potassium formate and potassium chloride fluids. Samples of mud were prepared by formate salts (sodium and potassium) and potassium chloride wi...
متن کاملConnecting high-temperature and low-temperature protein stability and aggregation
Protein aggregation is a long-standing problem for preservation of proteins in both laboratory settings and for commercial biotechnology products. It is well established that heating (cooling) can accelerate (slow) aggregation by populating (depopulating) unfolded or partially unfolded monomer states that are key intermediates in aggregation processes. However, there is a long-standing question...
متن کاملStability and Quench Protection of High-Temperature Superconductors
In the design and operation of a superconducting magnet, stability and protection are two key issues that determine the magnet's reliability and safe operation. Although the high-temperature superconductor (HTS) is considered much more stable than the low-temperature superconductor (LTS), it is susceptible to damage caused primarily by three events that can occur in large-scale "real" devices: ...
متن کاملStability of Methanol, Propanol, and Sf6 as High-temperature Tracers
Tracers are needed for the development of high-temperature geothermal resources. Several candidate tracers have been tested for that purpose in hydrothermal autoclaves at the Energy & Geoscience Institute in Salt Lake City, Utah. One gas tracer, SF6, and two of the two-phase tracers, the straightchain alcohols, were tested. They were tested at temperatures ranging from 220 to greater than 300C,...
متن کاملIslands of (In-)stability in High Temperature Superconductors
Dendritic flux penetration is a well known phenomenon in high temperature superconductors. We investigated the conditions under which this instability can be observed in different materials. We found three qualitatively different behaviors: dendrite development above a “critical field” and up to a certain temperature, above a “critical field” with no measurable temperature dependence, or no den...
