Abstract An operator was developing a High-Pressure High-Temperature (HPHT) field in the U.S. Gulf of Mexico (GOM). Completion design for the injector wells was cased-and-perforated, with no mechanical sand control. This led to the requirement for a tubing-conveyed perforating (TCP) system, featuring deep-penetrating (DP) charges which would meet specific performance requirements, in order to enable the wells to achieve injectivity targets. A perforating system was therefore developed and qualified to meet these requirements. This was an integrated system development, including both mechanical and explosive components, with simultaneous attention to performance, reliability, and quality assurance in the eventual field environment. The development program yielded a 4-3/4-inch carrier system, perforating charges, firing head, and gun hanger. All key components and systems were qualified in customer-witnessed testing, and demonstrated to meet or exceed operational function and performance requirements. The pressure and temperature rating of the newly-developed system is 30,000 psi at 425 °F. Explosive train function reliability was demonstrated at 380 °F for up to 28 days. The newly-developed perforating shaped charge was confirmed to exceed the stringent penetration depth and casing hole diameter performance requirements at downhole conditions. The firing head offers operational flexibility by being configurable for up to 15 pressure cycles prior to detonation, with an adjustable initiation threshold pressure to reduce risk to the completion string. The gun hanger was customized and demonstrated to exceed load requirements, and reliably set and release, in a test configuration featuring operator-provided field casing.

This paper is directed to the modification of jet fuels to reduce the inherent fire hazard of such fuels. Some of the problems and compromises involved in this development program are discussed. The theoretical concept pursued is outlined and some of the physical properties of the final compromise modified fuel are shown.

<p class="apa">This research was aimed to 1) study current conditions, problems, and needs of teachers for development and learning management in the extended educational opportunities schools (EEOSs: schools where they extended fundamental education from primary level of six years to lower secondary level of nine years), in Thailand, 2) develop the system of teacher development for the learning management, 3) implement and extend the results of study to other EEOSs. Research methodology was based on research and development approach which divided into three stages as follows: Stage 1) Preliminary study on current conditions, problems, and needs from related literature. The synthesis of related ideas and theories were then validated by the survey on the subjects representing school administrators and academic affairs teachers. Statistics used were percentage, means, and standard deviation. Stage 2) System development for the learning management was validated by nine educational experts. The validity of the system was based on feasibility and content appropriateness. Stage 3) Implementation of the system. The school performed teacher development program according to the procedures described in the manual. There were five research tools used which included: data survey, semi-structure interview, knowledge evaluation, learning management competency evaluation, and satisfaction evaluation. Research finding reported that the teachers needed professional development on professional training, study visit, and internal supervision. The system of teacher development has four main factors: input, process, output, and feedback. Overall, the system was the standard baseline for effective training in the EEOSs and possible to implement in other schools for learning management and student effectiveness.</p>
