ABSTRACT

The term of unconventional hydrodynamic trap refers to tilted
hydrocarbon-water contact caused by fluid flow driven by overpressure
gradient. In contrast, in conventional hydrodynamic trap, the fluid flow
is driven by hydraulic head gradient. The unconventional hydrodynamic trap
has been proven to be present in several major petroleum provinces in the
world, among others are in the North Sea and in the Caspian Sea areas. In
Indonesia, the giant Peciko and Tunu gas accumulations in the Lower Kutai
Basin have been proven as an unconventional hydrodynamic trap. Recently,
some parts in the Nilam Field in the same basin are also recognised as
unconventional hydrodynamic trap.

In the giant Arun Field, the tilted gas-water contacts have been
recognised by the previous investigator with no satisfactory explanation.
Also, in the giant Tangguh Field, variable gas-water contact and flank
accumulation have been recognised, and they are partly explained by the
concept of perched water. In this paper, we offer the unconventional
hydrodynamic trap as a plausible hypothesis to explain the circumstances
in the two giants above. Clearly, this hypothesis needs to be tested by
carefully analysing pressure data and presenting it in form of
overpressure map and pressure – depth plot.

This unconventional hydrodynamic trap is relatively new exploration
concept in Indonesia’s sedimentary basins, and hence the basins can be
said as under-explored with respect to this concept. The revisit of the
two giants above may be a good start to apply this concept, with the hope
to wake other giants up.

Welcome

Welcome to Zoho Writer body { font-family: Trebuchet MS; font-size: .9em; } p { font-family: Trebuchet MS; }

Welcome to Zoho Writer
Your Word Processor on the Web

 

Thank you for signing up with Zoho Writer!

 

Zoho Writer sports a new, refreshing and intuitive user interface. It is the word processor designed for you, the next generation web citizen. Built using AJAX technology, it’s fast and revolutionizes the way you work with documents. Having all your documents online (and offline too! we’ll get back to that later!!), you have access to them from any computer, at home or at work. And no more emailing them back-and-forth to your colleagues, clients or friends for review, thanks to its instant collaboration, inline commenting and chat facilities.

 

It will take a lot more than this short welcome document to list all of Zoho Writer’s features and hence a chosen few of the Zoho Writer’s functionalities are mentioned below :

 

Elegant User Interface

 

Zoho Writer has undergone a makeover with a newly introduced tab-based user interface. The features are categorized under different tabs for easy accessibility. You have the flexibility of navigating around any of the tab features with a single click, thanks to the friendly toolbar. Here is how the new UI looks:

 

Elegant User Interface

 

What’s more, each tab in the toolbar comes with a drop down arrow that lists the features in the form of pull-down menu. Browse through the features and apply them to your document at the same time using the pull-down menu, without having to navigate away from the existing highlighted tab.

 

Use formatting options – Bold, italicize, underline, color your words, set background color, link to a web page, set margins, use cool smileys cool and do much more. Use the same keyboard shortcuts as with any other word processing application for accessing these functions.

 

Enhanced Sidebar

 

The left-side bar, that lists all your documents (personal and shared), has some nice little enhancements in the version.

 

Enhanced Sidebar

 

Filters:
We have added few filtered views – "Shared by me", "My Public Documents" & "All". Look for the View menu in the sidebar.

 

File Info and Actions:
Along side each file in the sidebar, users will find an icon hovering over which will display the file info such as users shared to, public document etc. Users also have an action icon to Trash, Share, Rename or Export the specific file.

 

Page View Editing

 

The most requested and the much-awaited feature is out with Zoho Writer. Switching back-and-forth from edit view to page view will be a thing of the past. Users can edit their documents in "Page View" mode and get to know the print-layout of the document real time.

 

Page View Editing

 

And there’s no restriction on the language direction. Type content in LTR as well as RTL languages and in the same document too.

 

Users can also choose from among the various document page sizes – A4, Letter, Legal & Executive.

 

Document Info and More

 

Document InfoGet document related information both ways – with or without a click of a mouse. With the enhanced status bar, users will get real time info on the word & character count, number of pages, author nam
e and more. Clicking on the "Document Properties" button from the toolbar will display the relevant document info in the form of a pop-up window.

 

Improved Header/Footer

 

Improved Header/Footer

 

Add header/footer in your document on the fly. Choose from among the options of having them in one, two or three columns. There’s an auto-field feature too that lets you insert Page Number, Page Count, Current Date and Author Name into the document’s header and footer directly from the toolbar.

 

Document History – View & Compare Version

 

Messed up the current version of the document? Ever wondered if you could revert to an earlier version of it? With Zoho Writer, you can.

 

Document History

 

We create new versions of the document with each explicit save. At any time, you can view a document's history, seeing those previous versions and, if you want, reverting to an earlier draft.

 

Writer also lets you compare two versions of a document, so you can see specific changes and go back to version of your choice.

 

Spell Check

 

Spell Check

What’s a word processor without a spell checker? Zoho Writer’s does all the dirty spell checking work for you so that you needn’t worry about whether it’s receive or recieve wink

 

Moreover, the spell-check feature is available in more than 75 different languages. So it doesn’t matter whether you are typing your document in French or Swahili.

 

Tags as Folders

 

Tags as Folders

Get the best of both worlds . Tags are the new folders. Not sure whether you want to put a document in the Sales or Marketing folder?

 

That’s where tags-as-folders come in. Make the document available in both the folders! Now, you can click on "Tag Folders" in the Sidebar to view all your tag folders. Isn’t that cool?

 

Post to Your Blog

 

Post to Your Blog Being on the web, you can post to your blog from within Zoho Writer. As you have seen above, Zoho Writer’s WYSIWYG editor is more feature-rich than a typical blog editor’s. Be it Blogger.com, WordPress.com, LiveJournal, TypePad or any blog that supports metaWeblog API, you can make the post from Zoho Writer. You can add tags and optionally make the post as a draft as well.

 

Comments

 

Comments Add inline comments to particular paragraphs/sentences of a document. You & your friends (or your team members & your boss) can add comments in a document you are collaborating on.

Adding contextual comments is very useful for reviewing purposes. And this comes in handy for journalists/editors & teachers/students, in particular.

 

Share your Documents

 

Zoho Writer responds to the basic human need to connect with others – share a document with others & allow them to work on it.

 

When you share a document in Writer, you give others access to that document so that they can view it or, if you prefer, work on it with you. And all in real time — so when someone makes a change, the document gets updated for everyone.

 

Share your Documents

 

What’s more users have the flexibility of sharing the document with individuals on a personal level or share them with multiple users belonging to a personal/organizational group at once.

 

Go Offline

 

Not sure you’ll have internet access all the time? Zoho Writer allows you to take your documents offline. You can view as well as edit your latest 25 documents offline. Changes made during offline editing will be synced with the online version once you switch.

 

Integration With Other Zoho Apps

Several reference on: what is originality

http://courses.emu.edu.tr/grad601/Lecture%20Notes/Originality%20in%20research.htm

Facts, ideas and originality

Professor Michael Talbot of the University of Liverpool described the nature of originality in one of lectures to graduate students as:

 If we accept that there are two ingredients, facts and ideas, and that both may be either ‘new’ (never before presented to the world) or ‘old’ (familiar from earlier commentary), four possible combinations arise:

     1.     New facts + New ideas

     2.     New facts + Old ideas

     3.     Old facts + New ideas

     4.     Old facts + Old ideas.

 Combinations 1–3 all lead to originality. Only combination 4 is guaranteed to miss out on originality. Between them, combinations 1, 2 and 3 cater for an enormous variety of scholarly talents, temperaments and opportunities.

How to recognise and develop originality in research

For research to be of PhD standard, all institutional regulations require it be ‘original’, but the concept of originality is often misunderstood. This page offers suggestions, advice, tips and general help … more
