The offshore pilot test of Exxon’s Submerged Production System (SPS) has reached a successful conclusion. This pilot test encompassed the entire spectrum of SPS equipment, spanning from the well completion intervals to, but not including, common surface processing and storage facilities. Since the SPS is designed to meet all the life cycle needs of a subsea field, one of the objectives of the pilot test was to evaluate both the techniques and the equipment used to install, operate, and maintain a prototype version of the SPS. The equipment under test was designed for use in water depths up to 2000 ft, but with minor modifications it is capable of operating in significantly greater depths. Evaluation of pilot test results has shown that the deep water installation techniques are practicable and that the deep water maintenance machinery is competent to repair any failures likely to occur in an operating system. One of the most significant problems in conducting the pilot test was achieving adequate quality control during equipment manufacture. The test results have demonstrated that, with relatively minor modifications, the SPS is suitable for commercial application.

Riser Design

A multiline marine production riser and floating production, storage, and terminal facility may be required for economic development of oil and gas reserves in remote, deep water locations. A deep water production riser design has evolved through study, analyses, and model testing. In order to gain experience, development confidence, and improve the riser design prior to commercial application, a prototype has been built for testing as part of Exxon’s Submerged Production System offshore test in the Gulf of Mexico. This paper treats the design, manufacture, and installation of the prototype multiline marine production riser system.

Offshore Petroleum

Different equipments combined compose an offshore petroleum production system. Several development alternatives are available for a given offshore petroleum field. The selection of the most suitable system for a given scenario depends on field development characteristics and strategies such as its geographical location, water depth, environmental conditions and knowledge about similar systems already selected and in use for oil and gas production and available infrastructure in around. For the purpose of field production system design a database with types of production platforms, mooring systems, subsea equipments, reservoir main characteristics, type of wells and lifting processes is fundamental. Today, offshore petroleum reservoir production is more and more complex due to several variables involved and requirement needed to meet deep and ultra deep water depth, pre-salt petroleum with aggressive fluid characteristics, fields in remote areas and other environmental issues. Large fields in deep and ultra deep water are particularly challenging due to little availability of suitable platform types, among known concepts such as floating, production, storage and offloading unit (FPSO), semisubmersible, spar and tension leg platform (TLP). In the present paper, a database for worldwide offshore petroleum systems in use has been elaborated by searching data available in the literature. The database is organized for more than three hundred platforms distributed on more than four hundred different offshore oil fields. To serve as a basis for the conceptual design of a field production system, this database contains information such as type of the platform, field location, water depth, days for the first production, type of well, completion, mooring system, riser and offloading system. This information is structured for different water depth and environmental condition, for each field. From this database, analysis has been conducted for distribution of each type of platform by worldwide region, distribution of each type of platform by the offshore field by region, among others analysis. Concept of Utility Functions are applied to represent technological trends and to be helpful in the process. Among the results, a preference for FPSOs and semisubmersible was observed in Brazil offshore, semisubmersible, TLPs and Spars in Gulf of Mexico. In Europe, particularly the North Sea, FPSO, semisubmersible, and few TLPs have been found. In West Africa, most of the field production is based on FPSOs, although some semisubmersible and TLP could be observed. Similar analyses were conducted in other regions. Results and discussions show preferences regarding technology selected by each region, region historical data, and growth of water depth in different fields.

Abstract Both n-butane and iso-butane are important petrochemical raw materials, and their separation is of great significance and full of challenge because of their close boiling characteristic. The ZIF-8 slurry formed with a novel mixed solvent M-water solution as sorption media was adopted to separate the mixture with high efficiency. The iso-/n-butane selectivity of ZIF-8/M-water slurries is as high as 890 with high kinetic performance, even transcending the upper limit of the new materials or membranes. More encouragingly, continuous pilot separation device was established and test results show that the purity and recovery ratio of iso-butane product achieved 99.46 mol% and 87% respectively, which are remarkably superior to the corresponding performance (98.56 mol% and 54%) of the industrial distillation tower. To our best knowledge, this is the first industrial pilot test using MOFs for gas separation, and also an important step forward to the commercial application of MOFs in gas separation.

Girth Welds

Deep-water tendon and riser systems are often subjected to severe fatigue loading from waves, currents and vessel movements. The girth welds between successive lengths of pipe or at pipe terminations represent fatigue-critical features where failure would be catastrophic. Hence, validation fatigue testing by full scale pipes of the most critical welds are often performed to ensure adequate quality and/or to document a better S-N curves than those available in standards today like DNVGL-RP-C203 [1] and BS7608 [2]. To better understand the fatigue performance with respect to identify trends, dependencies and critical features that influence the fatigue performance, a JIP on Fatigue of Girth Welds were initiated in 2011. Two phases have been conducted and a total of 1700 full scale one sided girth welds, mostly run by Stress Engineering, have been statistically analyzed. The test data has been interrogated to investigate the effect of as-welded condition, OD ground, OD/ID ground, un-reeled pipe, reeled pipe, thickness and effect of misalignment. Based on these analyses, new S-N curves for risers and pipelines have been included in DNVGL-RP-C203 for non-reeled girth welds. This paper presents the findings and trends from the JIP work which has been the rationale for the updates of girth welds in section 2.10 in DNVGL-RP-C203 2016 edition.

Exploration And Development

In recent years, China has made certain achievements in shallow sea petroleum geological exploration and development, but the exploration of deep water areas is still in the initial stage, and the water depth in the South China Sea is generally 500 to 2000 meters, which is a deep water operation area. Although China has made some progress in the field of deep-water development of petroleum technology research, but compared with the international advanced countries in marine science and technology, there is a large gap, in the international competition is at a disadvantage, marine research technology and equipment is relatively backward, deep-sea resources exploration and development capacity is insufficient, high-end technology to foreign dependence. In order to better develop China's deep-sea oil and gas resources, it is necessary to strengthen the development of drilling and completion technology in the oil industry drilling engineering. This paper briefly describes the research overview, technical difficulties, design principles and main contents of the completion technology in deepwater drilling and completion engineering. It is expected to have some significance for the development of deepwater oil and gas fields in China.

Two Phases

Behaviour affects performance and productivity of poultry birds especially chickens, some behavioural traits are advantageous in a particular production system and may be of disadvantage in another production system. The present study compared behavioural of Nigeria Local Chicken, NLC (two separate samples of 11 Yoruba Ecotype) and its Exotic counterparts (11 Broilers and 11 Pullets) by use of the Open Field (OFT), T-Maze, Forced Approach, and Voluntary Approach Tests (FAT and VAT respectively) during two phases of Growth (0-4 Weeks, and 4-8 weeks age respectively). The former group (NLC) is better adapted to extensive management in the Nigerian Guinea savannah than the latter Results showed that Yoruba NLC issued a significantly (p<0.05) higher number of distress calls than the Exotic genotypes in the OFT at age 7 and 48 days, and the NLC issued significantly more calls at 7 days age. Broilers exhibited significantly lower OFT Latency at 7 and 48 days, and Broilers traversed fewer squares and spent less time ambulating than other genotypes at 48 days age. Ina T-maze, Broilers showed significantly (p<0.05) lower exploratory behaviour than other groups (higher latency to leave the start box). In the FAT, NLC showed lower Latency to flight (p<0.05) than the Exotic genotypes. Ethological test results indicate differences in the behavioural characters exhibited by Yoruba NLC and Exotic Chickens and such differences could embody the basis of anecdotal differences in the rates of survival under extensive management conditions, and may be subjected to quantitative genetic selection in the ongoing effort to produce improved chickens that incorporate a combination of desirable traits from both Local and Exotic chickens.
