This document discusses a study of the rheological properties of waxy crude oils from reservoirs in the Cambay basin. The objectives are to study the properties of crude oils under static and dynamic conditions at different temperatures, and to study the effect of adding pour point depressants. The methodology involves characterization of the crude oils using cross polarized microscopy, rheometry, FTIR, GCMS, and retesting the crudes after PPD treatment. The results will be analyzed to understand the properties and behavior of paraffinic crude oils to optimize facility design.

However, to comply with the still more stringent regulations being placed on the sulfuric acid industry to lower SO2 emissions, Topsøe has developed a new sulfuric acid catalyst designated VK-701 LEAP5™. This catalyst was introduced to the market in 2010. VK-701 LEAP5™ is based on a novel technology which circumvents the internal transport deficiencies of existing commercial sulfuric acid catalysts and thereby offers exceptionally high activity in strong gases. Since the introduction of this catalyst, sulfuric acid plants have used this catalyst to meet emission requirements lower than previously possible with any catalyst solution.
During Cobras, Topsoe will present examples on reducing SO2 emissions during both Start-up and steady operation, by implementing a tailor-made catalyst solution using VK59, VK69 and VK-701 LEAP5™.

Evaluation of CO2 Storage Capacity and EOR in the Bakken Shale Oil ReservoirsHamid Lashgari
This paper presents a new perspective in modeling and analyzing efficiency of CO2 and miscible gas injection for potential enhanced oil recovery (EOR) and CO2 storage in shale oil plays. Our major focuses are conceptual and fundamental understanding of the dominant trapping and oil recovery mechanisms behind miscible gas injection. The efficiency of the CO2 Huff-n-Puff process in shale oil production has been widely investigated in recent years because of the ultra-low permeability (1 to 100 µD) of shale oil reservoirs and poor geological connectivity between hydraulic fractured wells. Here we used hydrocarbon fluid properties of a Middle Bakken tight oil reservoir, and considered a wide range of permeability (from 1 to 100µD) and isotherm adsorption properties for CO2 and CH4. A large scale numerical model was set up to simulate and capture the important mechanisms behind various miscible gas injection scenarios.
Simulation results reveal that CO2 adsorption and CH4 desorption along with molecular diffusion of hydrocarbon components are crucial in the presence of organic matter content and pores, however, recycle enriched gas injection demonstrated a high oil recovery compared to miscible CO2 injection. Although CO2 adsorption is large in organic rich shale oil based on literature measurements, CO2 efficiency in enhancing oil recovery is not as much as recycle enriched gas with ethane (C2). However, CO2 trapping may be substantial due to adsorption (5.0% to 10%) and other conventional trapping mechanisms, and the amount of CO2 trapped could be a significant fraction of the total injected amount (25% to 50% considering other trapping mechanisms such as CO¬2 dissolution, residual, and free gas). Simulation results strongly support that CO2 molecular diffusion can assist in the deep penetration of CO2 to touch larger surface area of matrix to become adsorbed, as well as dissolved in other coexisting phases and residual trapping.

Introduction
Maxillary and mandibular teeth should contact uniformly on closing to allow optimal function, minimize trauma to the supporting structures and allow for uniform load distribution throughout the dentition.
Occlusion - The static relationship between the incising or masticating surfaces of the maxillary and mandibular teeth. GPT -9
Centric relation - a maxillomandibular relationship, independent of tooth contact, in which the condyles articulate in the anterior-superior position against the posterior slopes of the articular eminences; in this position, the mandible is restricted to a purely rotary movement; from this unstrained, physiologic, maxillomandibular relationship, the patient can make vertical, lateral or protrusive movements; it is a clinically useful, repeatable reference position.
Centric Occlusion [CO] - the occlusion of opposing teeth when the mandible is in centric relation; this may or may not coincide with the maximal intercuspal position.
Maximum Intercuspation [MI] - It is the maximum interdigitation of the maxillary teeth with the mandibular teeth independent of condylar position.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

1. Rheological study of waxy crude oil
example from Cambay basin
reservoir

3. Current Scenario
• As production from
conventional oil
reserves declines at a
rate of about 5% per
year, global demand is
rising steadily
• In this environment,
heavy-parafinic oil is
playing an instrumental
role in reserve
replacement
4. Complications in heavy crude
production
• When the fluid temperature
falls below the WAT there is
wax deposition in the
tubing/piping . Wax
deposition will reduce the
effective flow area and may
lead to complete pipe
blockage
• The precipitation of wax
components out of the oil is
responsible for the changes
in waxy crude oil properties,
including the gelation of oil
and increase in viscosity
5. • Therefore it is very
important to
understand the
properties and behavior
of paraffinic crude so
that the design of the
facilities can be
optimized according to
the nature of crude
6. OBJECTIVE
• The objective of this project is to study
rheological properties of waxy crude oils from
Cambay basin reservoirs for flow assurance
• Study of crudes in static and dynamic condition at
different temperature.
• Study of rheological property of crudes before
and after adding different doses of pore point
depressant.
• Developing a correlation between above analysis
& SARA analysis of crude to form a generalize
solution

8. CROSS POLAR MICROSCOPY
• Polarizing microscopes are used in the study of thin
sections of minerals and rocks as well as other
anisotropic materials (fibers, plastics, etc.).
• Anisotropy is the property of being directionally
dependent, as opposed to Isotropy, which implies
identical properties in all directions
• This test method consists of determining the wax
appearance temperature (WAT, or cloud point) of a
crude oil by measuring the temperature at which wax
crystals can be seen via microscopy under cross
polarized light
• The oil sample is placed between the cross-polarized
filters, and any crystalline material present will rotate
light allowing the light to pass through the second
polarization filter

17. CONJECTURE
• The anisotropic nature of wax crystals allows
their size and shape to be determined by CPM
• From Studies it has been established that
Microcrystalline (paraffin) waxes were found
to have larger, elongated structures compared
to the smaller, rounded microcrystalline
(naphthene and iso-paraffin) waxes.
19. FURTHER AGENDA OF THE PROJECT
1
• Physical properties & Behavior in dynamic condition
• Study with Rheometer
2
• Chemical Composition
• FTIR, GCMS
3
• PPD TREATMENT
• Tests are reperformed after adding different doses of PPD &
behavior is monitored
4
• CORRELATION OF GATHERED DATA & CONCLUSION
20. Rheometery
• Heavy – paraffinic crude
tend to change its behavior
&physical properties under
applied shear stress .
• In this test the rheological
properties of crude are
studied at different applied
shear stresses
21. FTIR
• FTIR- Fourier transform
infrared spectroscopy (FTIR) is
a technique which is used to
obtain Raman scattering of a
solid, liquid or gas
• FTIR radiation is passed
through a sample. Some of the
infrared radiation is absorbed
by the sample and some of it is
passed through (transmitted).
• The resulting spectrum
represents the molecular
absorption and transmission,
creating a molecular
fingerprint of the sample
22. GCMS
• Gas Chromatography
Mass Spectrometry (GC-
MS) is a technique for
the analysis and
quantization of organic
volatile and semi-volatile
compounds
• Gas chromatography (GC)
is used to separates
mixtures into individual
components using a
temperature-controlled
capillary column
• Mass spectrometry (MS)
is used to identify the
various components from
their mass spectra
23. PPD Treatment
• From the above result we observe that different crudes
showed different wax structure . some of them show a
rounded microcrystalline structure while other showed
larger elongated Macrocrystalline structures .
• So after the test different PPD are selected for different
type of wax.
• Pour point depressants (also known as PPDs) are polymers
that are designed to control wax crystal formation in
lubricants resulting in lower pour point and improved low
temperature flow performance
• All the tests are reperfomed by adding different doses of
PPD selected , the change in appearance as well as
chemical & physical behavior is monitored
