Prospect identification

Prospect Identification is general data about the prospect - what it's called, where it is and so on.

The data are entered into a single dialog with a number of tabs. Not everything needs to be filled in (see below) but the more you do fill in (especially comments) the more useful your analysis will be to colleagues and those who come after.

The tabs are:

Note: 1. Entries with a light blue background must be filled in.

2. Values may appear in three different colours: red is the program default, blue is a value calculated from elsewhere in the prospect dataset and green is a value that has been entered manually.

ID: General

pr_id1

Reserves class is the reserves classification to which the prospect reserves are assigned.

[Note: The classes can be defined to suit your particular scheme. Email us for instructions.]

Reference is a free text entry for your convenience. It is not used by the program. It is shown at the bottom of printed pages.

Pre/post-drill and Evaluation refer to the current evaluation stage. See our section on 'Prospect Evaluation' for more information.

Name
Prospect name	Enter the name of the prospect
Reservoir name	Enter the reservoir name
Segment	Enter the prospect segment name, if you are analysing just a bit of the prospect (e.g. a particular fault block).

Location
Country	Enter the country in which this prospect lies. [Note: Recent and continuing political excitements mean that our list (which is the United Nations ISO standard) is generally out of date. It can be easily changed and if you need to do so please contact us for information on how it can be done.]
Set as default	Click to enter default country (as defined in Set up and defaults)
Region/State	Enter the region, state or other sub-division of the country.
Block	Enter the block in which this prospect lies
Well	Associated well name - presumably the exploration or discovery well. If you have a valid project (i.e. not the default project) new wells are added to the project and can be chosen from the dropdown list.

Classification	all these are drop-down options
Status	The prospect status can be Concept, Lead, Prospect or Discovery
Prospect class	Enter the classification for this prospect - see list
Reserves class	Enter the reserves classification for the prospect/discovery. The list is based on the PRMS classification.
Drilling status	Enter the drilling status
Pre/post-drill	Is this pre- or post-drill?
Evaluation	Enter the name of the current evaluation. See evaluations

Custom attributes	These are user defined prospect/field attributes which are stored with each asset but also defined for the project
Name	The attribute name
Value	The attribute value
Add/configure	Add and edit the current set of attributes. Click here for more instructions
Delete	Delete the current attribute. If you want to do this (and you are reminded of it) the attribute will be deleted in the project and all the assets it contains

Licence

pr_id2

Licence
Licence/concession name	Enter the licence in which the field/prospect lies
Production interest %	Enter your company's percentage interest in any revenue from prospect. It is used by the program to convert gross (whole trap) volumes to net (company share) volumes.
Exploration interest %	Enter your company's percentage working interest - the proportion of the costs that your company will pay. Note that this is often (if not usually) higher than the production interest.
Block share %	Enter the share of the accumulation in the given block

Operator
Operator	Enter the operator of the licence
Set co.	Click to enter default company name - this will be the name of the company entered in "Setup and defaults", and is presumably your own company's name.

Admin
Group/unit	Enter the business unit/user group/client. The arrow to the right copies the entry from your user set-up entry.
Set as default	You can set the above entry as your user default, by clicking this button
Reference	Enter a reference number/string

Designated hydrocarbon type
Hydrocarbon type	Choose from the list
Fixed	If the Fixed box is unchecked, REP will decide the designated hydrocarbon type at the end of a calculation. It does this by comparing the volumes of oil, gas (as oil equivalent) and oil + oil-equivalent gas condensate, whichever is the higher. If Fixed is checked you decide; and your wishes will be respected.

Geological Setting

Play
Basin	Enter the geological basin in which the prospect lies
Play	Enter the play of which the prospect forms a part

Details	.. see also the retrieve button below
Depth datum	Select from which level the prospect depth should be measured
m <> ft	Click to change units of depth
Datum depth	Enter the height of the datum above mean sea level/ground level
Depth to crest	Enter the approximate depth to the primary target
Depth to base column	Enter the approximate depth to the base of the reservoir column
Column height	Enter the approximate column height
Reservoir thickness	Enter the approximate gross reservoir thickness
Trap area	Enter the approximate trap area
km2 <> acre	Click to change units of area
Retrieve	Most of the parameters above will be entered later as prospect parameters that are used in the calculation. This retrieve button gets them from entered data. So rather than enter all the data above before you'vce done the main analysis, leave them blank, do the analysis, come back here and click retrieve. Voila!

Geographical Setting

pr_id4

Onshore/Offshore	Circumstance of prospect
Terrain	Onshore prospects - choose the environment
Water depth	Offshore prospects - the water depth
Nearest facility	The nearest processing station (where the hydrocarbons are delivered) ...
Distance	.. and how far away it is.
Location	This can refer to either the exploration well, or be a more general indication. Entry can be either by UTM's or lat/longs. If you specify both the UTM central meridian and the Lat/long spheroid a conversion can be made between the two.
Meridian	The zero point of the UTM easting
Southern hemisphere	Check if the location is south of the equator
Spheroid	The spheroid used for the lat/long coordinates. WGS 1984 is the standard for GPS, but many exist, and most are in the drop-down list.
North/East	The UTM coordinates
N/S	The latitude in format dd mm ss.ssN (or S)
E/W	The longitude in format dd mm ss.ssE (or W)
GIS ID	This is an identifier to link the prospect file to a GIS entity. It should be supplied by your GIS administrator.

Maps and Other Image Files

pr_id6

On the printed output sheets, space is left for various maps. There are two ways to fill in these boxes: skilful use of a photocopier, or specifying jpeg, bitmap files or other image files, if you have them somewhere on your system.

You can have up to twenty maps or images. The first two in the list are shown side by side near the top of the Summary Page of the printout. If you do a Full Page printout, the first map is also shown on the front page, and all the other maps are shown on succeeding pages, one to a page. The images can be rearranged using the [up] and [down] buttons.

In the dialog, click the [Add] button to add an image file. Once the desired file is found, click [OK] and it is added to the list on the left. To edit an existing entry, click on it in the list.

Each map or image may be given a title. There is a drop-down list of common titles ("Seismic section", "Location map" etc.) but you can enter anything you like ("Compromising picture of CEO", for example).

For an image, check the box 'Preserve aspect ratio" to ensure that the image will not be unequally squeezed to fit the space on the printed sheets.

You can also ask to rotate the image on the page.
