General Information

Introduction

SafeVision Standalone allows users to “drill the well on the simulator”, displaying with

clear and simple graphics various critical relationships occurring below the rig floor.

The heart of the program is an advanced, fully transient hydraulics module optimized

to quickly simulate complex wellbore relationships.

The common display contains prioritized information rather than excessive raw data.

The emphasis is on providing a thorough overview of current well status using a

depth-based graph linked to a detailed well sketch. Display of time-based data is

optional and may be customized by the user.

Standalone Features

Well Visualization

•

Well sketch provides continuous display of well geometry

• Well sketch shows scaled diameters and depths

•

Sketch updates to display results of transient simulations• Depth-based graph is linked to the well sketch and displays critical downhole

pressures and pressure limits. This can be displayed in either equivalent density

or pressure units

• User-defined time-based logs can be used to record progress of simulations and

identify relevant operational events

Applications

• Helps demonstrate effect of surface actions on entire downhole well profile,

fully integrating multiple, simultaneous effects.

• Calculates and continuously displays pressures at all well depths, thus

clarifying critical relationships.

• When used to simulate drilling, consequences of complex changes in pore

pressure, formation strength, hydraulics, geometry and string movements can

be assessed

• Simulates well conditions with the BOP open or closed

Other Features

• Kick Tolerance Analysis

• Automated sequence controls enable simulation of drilling, tripping, and fluid

displacement processes without specialized skills• Fully transient simulations make it easy to “drill the well on the simulator”

• Simulation data is automatically recorded for easy play back and can be

optionally saved for later reference

• Optimized mathematical models allows for fast simulation of complex well

scenarios





Installation

System Requirements

The SafeVision simulator utilizes highly efficient solution methods; therefore,

compared to its functions the required computing power is relatively low. Below are

computer system requirements for SafeVision.

•

SafeVision is designed to run on Intel and AMD processors. ATOM processors

(netbooks) are not recommended.

• Minimum system requirement is a duo core processor and 4.0 GB of RAM.

• SafeVision is compatible with Windows XP, Windows Vista and Windows 7

operating systems.

• Minimum screen resolution is 1024 x 768 pixels.

• SafeVision is visualized via an installed Web Browser. We recommend Google

Chrome but the software is also compatible with Internet Explorer version 9.0

or above.

Please note that if you have any previous versions of the SafeVision Standalone

installed on your machine we recommend you uninstall them before installing a new

version.

Installing SafeVision Standalone

Once you have received your installation file please double click on it.

Follow the instructions and once the installation is finished a “SafeVision 2.0” icon will

appear on your desktop.

Double click on it to open and run SafeVision.





Running a simulation

When you run the software the first screen you will see is the one below. It has the

Menu on the left for Well and other configurations and 3 simulation examples.

If you click on the play button on the side of any simulation you will be taken to

the Standalone Simulation screen.

Please note that if it is the first time you are starting a simulation for a section the

drill bit will be at surface.





The following operations can be performed using the simulator:

• Back Reaming

• Circulating

• Drilling

• Pumping Out

•

Reaming• Reaming Down

• Sliding

• Tripping in

• Tripping Out

• Waiting

• Washing Down

When an operation is selected, relevant and required input variables will becomeavailable.

Back Reaming

This operation requires the user to specify drill pipe rotation (RPM), flow rate down

the drillstring and the rate at which to trip out of hole. Therefore the minimum

required parameters for this operation are:

• “Back Ream to”. This is the location to trip to, it can either be specified under

“specific depth” or a location can be picked from either, Surface, Casing Shoe or

Well bottom.

• Tripping Speed

•

Flow Rate in• RPM

Please note for all operations additional information can be entered if required based

on the flow path configuration. For example, for deep-water applications, if a booster

flow rate and mud weight is required please enter these values.





Circulating

The following parameters are required:

• Flow Rate in

• Duration

Drilling

This operation requires the user to specific drill pipe rotation (RPM), flow down the

drillstring, rate of penetration (ROP) and a depth you want to drill to. Therefore the

minimum required parameters for this operation are:

• “Drill to”. This is the depth to drill to.

• ROP

•

Flow Rate in• RPM

•





Pumping Out

This operation involves tripping out of hole while circulating, without any drill pipe

rotation. Therefore this operation requires the users to specify the following minimum

parameters:

• “Pump to”. This is the location to trip to, it can either be specified under


Well bottom.

• Tripping Speed

• Flow Rate in

Reaming

This operation involves circulation with drill pipe rotation for a period of time.Therefore the minimum required parameters for this operation are:

• RPM

• Flow Rate in

• Duration





Reaming Down

This operation involves tripping into hole while circulating, with drill pipe rotation

(RPM). Therefore the minimum required parameters for this operation are:

• “Reaming Down To”. This is the location to trip to, it can either be specified

under “specific depth” or a location can be picked from either, Surface, Casing

Shoe or Well bottom.

•

Tripping Speed

• Flow Rate in

• RPM

SlidingSliding is way of drilling but this operation does not involve any surface drill pipe

rotation (RPM). Therefore the minimum required parameters for this operation are:

• “Drill to”. This is the depth to which that you like to drill.

• ROP

• Flow Rate in





Tripping in

For this operation the minimum required parameters are:

• “Tripping To”. This is the location to trip to, it can either be specified under


Well bottom.

• Tripping Speed

Tripping Out

For this operation the minimum required parameters are:

• “Tripping To”. This is the location to trip to, it can either be specified under


Well bottom.• Tripping Speed





Waiting

For this operation the minimum required parameters is only Duration.

Washing Down

This operation involves tripping into hole while circulating, without any drill pipe

rotation. Therefore the minimum required parameters for this operation are:

• “Wash to”. This is the location to trip to, it can either be specified under


Well bottom.

• Tripping Speed

• Flow Rate in

Once you are done setting up the operation click on play to start the simulation. To

view the time based graphs click on the Main tab

Kick Tolerance Screen

Kick Tolerance is based on current well bore limitation.

The Kick Tolerance screen allows for method selection and data entry for kick

tolerance calculations. In addition, it provides calculation outputs in tabulated form

and graphs. The kick tolerance screen is in turn split into two tabs: Setup and Results.

Setup





Kick Tolerance data entry consists of two fields:

Pore Pressure Calculation Method

Pore pressure calculation method has to be selected from one of the two options

below.• Kick Intensity + Pore Pressure

• Kick Intensity + Mud Weight

Data Input

Various operational, influx fluid, and calculation boundaries related parameters can be

entered in this area. These parameters are:

•

Influx density.• Kick intensity at which the current kick tolerance is displayed on the current

status bar.

• Kick intensity range min and max.

• Option to use pressure and temperature corrected downhole mud density.

• Option to define a weak zone in addition to the shoe. The software will

automatically ascertain the limiting depth.





Using the various refinement options you are able to select additional parameters that

influence kick tolerance to be taken into account by the software:

• Temperature affects

• Gas Compressibility

• Influx density correction

• No expansion

• Choke operator error

• Choke line friction

• Annular friction

The No Expansion option should be used in cases of water kicks or when the last

casing shoe is deeper than the bubble point depth, meaning the gas that entered the

wellbore will behave like liquid throughout the entire open hole section.

Results

The results tab displays the calculated kick tolerance graphically with the X-axis

showing volume and Y-Axis the Kick intensity.





Directional Screen

The directional screen gives the user the vertical and horizontal projections of the

well. The vertical projection also shows the position of the bit and last casing shoe.

Horizontal

Projection

Vertical

Projection

An additional feature

on the directional tab

is a TVD calculator.

Simply enter the MD

on the left field box,

click calculate and

the corresponding

TVD value will be

calculated

The Vertical

projection not only

shows the well

profile but also

displays the last

casing point and the

current bit position.

The position (shown

by a dot) will track

with bit movements

The horizontal axis

can be manually

adjusted to fit the

well profile





Well Info Screen

This tab allows all users to view information related to:

• Pump Data

• SCR’s (Slow circulation rate)

• LOT (Leak off test)

•

Hole Volumes

Pump Data

The following pump

information can be stored

and accessed at any given

time:

• Pop-off pressure

• Pressure rating

• Stroke Length

• Liner size

•

Pump Efficiency• Pump Displacement

Obs: In order edit the parameters on Well Info Screens please make sure that you

have added these features on the Workstation menu. Details of setting up the

features are on the Workstations Chapter.





SCR’s

Users can input slow circulation rates for up to four pumps. Click on “Add row”, a pop-

up window will appear for data input. As drilling progresses and wellbore conditions

change you can add additional rows to the SCR table.





LOT

Leak off test tab allows for the estimation of the maximum allowable annular surface

pressure (MAASP) based on current conditions. User can input the LOT information:

•

Leak off test surface mud weight• Leak off test surface pressure

• Weak point, TVD. You can either choose to enter the shoe depth or other depth

if a weak zone below the shoe is known.

Important to note that this LOT information here will not automatically update the

fracture pressure curve being plotted in the ECD/Pore/Frac depth based graph. It will

also not be used to update the KT calculations. To update the Fracture Profile

displayed on the Main Screen it will be necessary to change the information enteredon the Formations Tab.





Hole Volumes

Hole volumes and time required for circulation is calculated taking into account the

well configuration and are updated based on current BHA dimensions, well depth, bit

depth and pump speeds. The “Pump Displacement” calculated in the “Pump data” tab

is used here to display the circulation time in “minutes” and “strokes”.





Well Control Screen

The well control tab becomes automatically active once the BOP is closed in the

software. In order to be able to close the BOP please confirm that your console has

the Enable BOP Button ticked in the features page. Once this is confirmed to close the

BOP please follow these steps:

1. Click on “Wrench Tool” (wrench)

icon on the top right on the screen.

2. Under the drop the menu, click on

“Well Status Updates”.

3. On the “Select a parameter to update” window click on “BOP”.

4. On the “BOP” window use the BOP state drop down menu to close the BOP.





5. A new drop down menu will become available to specify the reason for the BOP

closure, please select from one of the options listed.

6. Next select the flow path for the kill and choke lines from the drop down menu

available. If the alignment chosen by the user is “closed”, the HCR valves in

SafeVision™ will be closed, which will prevent the ECD curve to be updated with

the choke/kill pressures.

Once the BOP is closed you will see the operation status change to “BOP Closed – Well

control” (changes based on user specified reason for BOP closure). If you click on the

“Well Control” tab you will see the graphs being plotted, as the simulation progresses.

The well control tab is split into three panels:

•

Gauge Display• Main pressure plot & Kick Data

• Time based charts

Gauge Display

There are two fixed gauges, Standpipe and Choke pressure. The other is user

configurable for a choice between either Kill Line pressure or BOP pressure sensor.

The range for each gauge can be individually configured. To change the range, please

click on the Settings. The pop up window gives the options to select from preset

default ranges or to use a custom range.





Building a Simulation

There are 2 ways of building a new simulation. Users can duplicate a current

simulation or create a simulation from scratch from the “Wells” tab on the left menu.

If you are duplicating from an existing simulation

Give it a name

Define data point start (first or current)

If you choose current data point the simulation will start with a snapshot of the last

parameters on the pop-up window or importing from a file by pasting the data

If you are inputting the data manually click on “+ Add Row”, a pop-up window will

appear. On this window parameters can be inserted manually or using the list/table. If

you use the list/table, after choosing your parameters click on select. Then check if

the values are correct and click on “Save Changes”.

Important: The Drillstring is created from the bottom up, i.e. from bit to drillpipe.

Therefore the first item on your table should be a Drillpipe with 0 (zero) length so

the top section of the Drillstring will be adjusted automatically by the software

with the hole depth.





Please Note: BHA items have no pre set values and all have to be entered manually.

The comments column can be used for a description of the item.

An equivalent “hydraulic ID” value for mud motors, MWD, turbines etc, where actual

ID probably won’t be available, but pressure drops may be approximated by using

(user defined) ID’s that bring simulated standpipe pressure values into realistic ranges

can be entered in the Inner Diameter box.

Also, OD for stabilizers should be body OD or the equivalent hydraulic OD if known,not blade diameter (i.e. a “12 !” stabilizer may need to be entered with an 8 "” OD

or the hydraulics model will calculate excessive/unrealistic annulus friction).

If you want to change the sequence of the rows just drag and drop them in the

desired order.

Once your drill string sections are completed please add the parameters on the fields

below. Please note that if there is a Float Valve in the string the “Float Valve” box

needs to be checked.

Bit Nozzles information can be entered manually by clicking on “+ Add Row” or via the
