1 The hydrogen to carbon weight ratio of residual oil is approximately 1 to 9.

2 Note that residual oil is approximately 1. 6 whereas coals vary around 0. 8.

3 Asphaltic resins were synthesized from residual oil and FCC slurry in laboratory.

4 Residual oil evaluation is important for optimizing in full well location and improving reservoir management.

5 Emissions from ships using heavy residual oil, and also power stations,[] have been a major problem.

6 Evaluation of residual oil saturation is the difficulty and key in the water flooding zone interpretation.

7 Thoroughly presents various logging technologies for residual oil saturation, including nuclear logging, electric logging, acoustic logging and the like.

8 Regarding the good reservoir residual oil distribution is scattered, used the polymer displace oil.

9 The need for determining residual oil saturation ( S OR ) has existed.

10 Residual oil on engine parts also provides lubrication for engine start - up.

11 Predicting residual oil distribution is the main task in the middle and period of oilfield development.

12 Based on vacuum residual oil hydrodesulfurization plant of some refinery, simulates and optimizes typical hydrogenation plant.

13 Combine with living examples, the oxygen - residual oil control system in Texaco chilling gasification technology is introduced.

14 These reasons rest largely upon the intermediate nature of various properties of residual oil as compared to gas and coal.

15 This paper compared two different typical combined processes in processing sour residual oil.

16 The resistance factor and the ratio of the resistance factor to residual resistance factor of the flooding system in presence of residual oil are decreased substantially.

17 So the combination of ground and down hole superconductive gravity is one of practicable method in further prospecting of residual oil.

18 The logging technique is an important and efficient method to detect the residual oil saturation.

19 After polymer flooding and polymer cross link micro gel flooding, the residual oil mainly distributes in middle and low permeable reservoirs. This is the potential area of EOR.

20 The postponable reduced viscosity process is a thermal cracking one of shallow degree of residual oil.

21 At present, seeking the residual the reasonable extracting of residual oil is one of primary problem.

22 Further studies on this project should provide key parameters for interpretation of oil and residual oil saturation of shaly sandstone reservoir bed.

23 Its manufacture process includes the deasphalting of the vacuum-pressure residual oil, solvent refining, solvent-dewax, refining, shaping and packing.

24 An experimental study on non - isothermal flow resistance for Coke - Residual Oil Slurry ( POS ) in tubes was made.

25 Panhe Fault - block entered high water - cut development stage and residual oil are scattered.

26 Genesis of reservoir is the geologic setting of influencing the residual oil distribution.

27 Based on the theory of gravity prospecting and measuring accuracy of superconductive gravimeter, the migrating and accumulating of residual oil and gas are studied.

28 In the condition of oil wet, the micro - residual oil exists in block like dendrite - residual oil forms.

29 In combination with flow seepage theory, a vadose model for the turbidite oil reservoir was established. The distribution patterns of residual oil were summarized.

30 The 4D geology model is helpful in finding out distribution of residual oil, adjusting development plan, and improving ultimate production factor.

31 It can be used in various operations of heavy and residual oil coking process.

32 Depending on the characteristics of the residual oil and the length of the blowing time, asphaltic materials of varying characteristics are produced.

33 Core analysis data from laboratory showed the origin of water layers with high resistivity is due to changes of lithology, residual oil and formation water salinity in local areas.
