In oil and gas applications where centrifugal compressors play a central role, their availability is essential for continued production; typically the loss of a day’s revenue can far exceed the capital value of the machine. Performing more rigorous inspection and testing prior to accepting delivery of centrifugal compressors can reveal a fairly large percentage of mechanical and performance failures. This paper is devoted to illustrate the crucial importance of centrifugal compressors testing within the petroleum industry with a special attention to the performance test and complete-unit test.

Crude oil separating is an important technological process in the petroleum industry. Pipe separation technology (PST) is a new kind of separating method in oil-water-gas separation. To compare with conventional gravity separators, the new separator based on PST is low weight, low cost, efficient and convenient to maintain. This paper introduces this new compact separator, technological process and performance test. The test results show that the compact separator has good separating effect. When the water-cut inlet is from 50% to 60%, and the mixture flow rate is from 40 t/hr to 100 t/hr, the water-cut in oil outlet is less than 5%, and the oil-cut in water is less than 100 mg/l.

Bulk Behavior

Swelling elastomers are a new breed of advanced polymers, and found increasing use in drilling of difficult oil and gas wells. It is important to know how an elastomer will behave under a given set of well conditions, especially after the initial quick-swell period. Good design depends on appropriate material selection. Results are presented in this chapter from experimental and numerical studies conducted to analyze how compressive and bulk behavior of actual oilfield elastomers changes due to swelling. Six key attributes of swelling elastomers needed for design improvement and performance analysis of elastomer seals are discussed: four mechanical properties (elastic modulus E, bulk modulus K, shear modulus G, and Poisson’s ratio ν), and two polymer structure characteristics (cross-link chain density NC, and average molecular weight MC). These parameters were experimentally determined before and after various stages of swelling for two different swelling elastomers being currently used by the regional petroleum industry, in low and high salinity brines. To strengthen the experimental results, and to be able to forecast for other elastomer materials and well conditions, tests were also simulated using the commercial FEM package ABAQUS, using the best available hyperelastic material models.

Expected Performance

The role of centrifugal compressors within the petroleum industry is critical since they are used in all aspects of gas processing such as gas lift, transmission and distribution, re-injection into reservoir for pressure maintenance, wellhead separator boosting, casing head gas collection, under ground gas storage and liquefaction for transport, [1]. Among those optional tests applicable to centrifugal compressors stressed in API STD 617, performance test demands a great attention, since it determines if equipment meets design or expected performance criteria and serve as a means to determine fulfillment of manufacturer’s guarantees. Having a working knowledge coupled with more rigorous testing prior to accepting delivery of centrifugal compressors can reveal a fairly large percentage of performance failures. The main purpose of writing this paper is to share the author’s experience of purchasing and testing centrifugal compressors within the petroleum industry. Furthermore, it attempts to address the potential pitfalls of a poor performance test procedure.

Composite Pipes

The goal of this experimental study is to manufacture a bolted GFRP flange connection for composite pipes with high strength and performance. A mould was designed and manufactured, which ensures the quality of the composite materials and controls its surface grade. Based on the ASME Boiler and Pressure Vessel Code, Section X, this GFRP flange was fabricated using biaxial glass fibre braid and polyester resin in a vacuum infusion process. In addition, many experiments were carried out using another mould made of glass to solve process-related issues. Moreover, an investigation was conducted to compare the drilling of the GFRP flange using two types of tools; an Erbauer diamond tile drill bit and a Brad & Spur K10 drill. Six GFRP flanges were manufactured to reach the final product with acceptable quality and performance. The flange was adhesively bonded to a composite pipe after chamfering the end of the pipe. Another type of commercially-available composite flange was used to close the other end of the pipe. Finally, blind flanges were used to close both ends, making the pressure vessel that will be tested under the range of the bolt load and internal pressure.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.

Negative Impacts

ABSTRACTWith much fanfare, Ghana's Jubilee Oil Field was discovered in 2007 and began producing oil in 2010. In the six coastal districts nearest the offshore fields, expectations of oil-backed development have been raised. However, there is growing concern over what locals perceive to be negative impacts of oil and gas production. Based on field research conducted in 2010 and 2015 in the same communities in each district, this paper presents a longitudinal study of the impacts (real and perceived) of oil and gas production in Ghana. With few identifiable benefits beyond corporate social responsibility projects often disconnected from local development priorities, communities are growing angrier at their loss of livelihoods, increased social ills and dispossession from land and ocean. Assuming that others must be benefiting from the petroleum resources being extracted near their communities, there is growing frustration. High expectations, real and perceived grievances, and increasing social fragmentation threaten to lead to conflict and underdevelopment.
