摘要:
The present invention provides a drilling fluid composition and a method of drilling comprising a drilling fluid, which may be oil- or water-based, and a composite microsphere component. The invention drilling fluid composition advantageously reduces the density of a conventional fluid, reduces costs associated with pumping and overcomes problems associated with conventional gas-injection processes. The invention uses conventional drilling and pumping equipment, requires no sea-floor based pumps and may be easily pressure-controlled to maintain the pressure of the fluid.

Methods, servers and systems for directly accessing and modifying charging information maintained within a telecommunications operator's business and operating systems' infrastructure from user equipment. A mobile application server may receive a charging request from a user equipment, identify a relevant charging system based on the received request, send a charging request to the identified charging system for processing, receive a first response message including charging information from the identified charging system, generate a second response message based on the charging information included in the first response message, and send the generated second response message to the user equipment. The received charging request may include various types of information, including information for transferring cost or billing information from a first billing category to a second billing category.
摘要:
Filled resin composites comprising at least one polymeric resin and microspheres wherein said microspheres have an average size D50 of 25 micrometers or less and a 10 percent collapse strength of at least 10,000 PSI (68.8 Mpa) are disclosed. Such resins exhibit surprising and previously unattained combination of superior physical properties. Articles made with such composites are disclosed.
摘要:
Block copolymers are suitable additives for polymeric composites containing microspheres. The block copolymers have at least one segment that is capable of interacting with the microspheres thereby enhancing the physical characteristics of the composition.
