In this presentation on industry best

practices for oil and

gas production and processing

we will share an overview of the key benefits

of

simulation and the capabilities required to

realize these benefits

Through examples we will showcase how Ansys

portfolio are helping

our customers design transformational

products and will close with

information on how to learn more

The three segments of oil and gas industry at

is

upstream midstream or downstream

They all are focusing on some key business

initiatives

Some of them are like improving reliability

and asset management

or improving pipeline availability and

reliability or to

comply with the codes and reduce the emission

and improve

sustainability

The industry faces some key engineering

challenges

In terms of meeting the regulations doing

maintenance optimization or

maintenance management which can affect the

operational cost which can

affect the safety and performance of their

asset or the

crew who is working on it

And these challenges needs to overcome in

order to achieve

the goals outlined in the key business

initiative discussed earlier

Now Ansys solution have helped our

customers

to overcome those engineering challenges

described earlier

They were able to get faster product

development

They were able to save on operations or

improve the

performance of their asset or even save money

by reducing

time to market and even reducing expenses on

expensive prototype

In the following slides we will take you

through some

of the simulation capabilities which help our

customer save millions

We have divided these capabilities into few

sections which we

will go briefly and then dive

deeper later in this presentation

Digital transformation so there are many

engineering challenges when we

talk about digital transformation be it

sensor design and placement analytics

platform integration or excessive maintenance

and inspection these are some

issues companies or folks face at the field

but our

Ansys capabilities of virtual sensors or

doing system integration

we have capabilities of doing multiobjective

optimization and even create

3D reduced order models now all these helps

companies to come up with a digital

transformation solution

Similarly under drilling and production our

capabilities of extensive multiphase

modeling the streamline analysis workflow

what we have or the

coupling of fluids in structural solutions

which can be done

will give us some output like erosion rate on

the

equipment or even determine the separation

efficiencies all these together

when you're doing this multiphysics modeling

you can do rapid

product development you can understand the

lifing the fatigue

life and the failure modes to improve the

design so

this way we can help in the drilling and

production

segment

Similarly the capabilities what I previously

mentioned do helps in

transport and storage part of oil and gas

journey as

well one can plan reliable problem resolution

strategies or ensure

proper design of storage tanks by predicting

sources of failure

like potential leakage buckling condensation

corrosion erosion this will help

even overcome the flow assurance problem such

as erosion corrosion

as I mentioned And will help prevent oil

leaks and

spills

Another important segment is equipment

reliability it's very much important

while you are running your analysis or while

you are

running your operations

you do not face failure in your equipment

because it

will cost a lot by by creating some unplanned

downtime

or by

Not meeting safety standards so that's why

where Ansys solution

can help as perform the structural mechanics

analysis or even

random vibration and fatigue analysis to give

you life of

your asset you can help predict and mitigate

the failure

or even ensure operational safety

With all these new challenges on new

technologies coming into

picture electrification is a big part of oil

and gas

initiatives in recent times

But electrification in such a harsh

conditions brings challenges in

itself about thermal management signal

integrity or energy management down

on the seabed so we have a nice

integrated functional safety analysis tools

there is an electric machine

modeling workflow available within Ansys tools

which can help you

do controller prototyping or design and

verification of your PCB

boards for that matter and with all these one

can

realize this benefits and get help from Ansys

tools in

electrification of certain assets

You can also see Ansys solutions for

electronic systems for

a more detailed

information on electrification capabilities

Once the gases are the oil and gas has been

produced and they are being taken from your

midstream section then

they have to be processed or refined before

it can

be used now the challenges for people face

in that

segment is reducing time to market right now

if you

want to scale up you can do all those testing

on a bench scale but you want to scale up to a

production scale without losing any yield or

any efficiency

The companies have built this plans

In 1970s 1960s some of them even older

than

that so retrofitting that old assets to

ensure that product

quality does not

get affected is also a big challenge

So customers there are using Ansys multiphase

models Ansys combustion

modeling tools or even the automated workload

for all these

two models application like mixing tank

fluidized bed they can

do bubble size distribution they can do

quantitative or qualitative

reporting or see a particle dynamics so this

all help

them come up with

answers for troubleshooting or improving the

design or even designing

a new application or asset itself

Finally while doing all these

processes or while going through his old

journey one important

thing which needs to be taken care of safety

and

compliance with the regulatory codes because

of the harsher operating

condition because of so many components from

many different vendors

at sometimes become very difficult for our

folks and that's

where our capabilities on multiphysics

coupled analysis or code checking

customization toolkit helps a lot to

determine the life

to make sure your asset is

performing by meeting the

regulations from the from

the regulatory bodies or even in case

anything goes wrong

what are the mitigation steps so we will see

how

these all things come into effect how the

customers are

using Ansys tools to

resolve these problems

We are now gonna dive little deeper into each

of

those capability breakout segment discussed

earlier

First we're going to see

some examples on digital transformation or

how Ansys solutions are

helping

As we discussed those challenges of sensor

design or placement

or reducing system downtime Ansys twin

builder can enable the

creation of digital twins for complete systems

what you're seeing

here in this video is an artificial lift

system and

you can see where it's located what system we

are

going to talk what we are going to use Ansys

multiphysics tools to connect to system level

model

and then create a digital twin what you're

seeing is

this tool a twin being created with

this

multiphysics models of motor of pipings of

pumps and this

is how the pump was working but now when sand

was introduced into the pump what you can see

on

the left side

If it is the is the life of your pump

of your asset being decreased and that is

somewhere here

and that's that gives some idea to the

operator

something is happening something is going

wrong now what you

are seeing is there are the sand and the flow

rate these are the things which are being

coming from

the sensors or the IoT platform

So what you see is once the issue was being

identified the operator can go back and

disconnect from the

platform and they can see what can they do to

improve this life which was 32 days now so

they're

trying certain what-if analysis by changing

the RPM by

reducing it decreasing it and seeing it if

that can

help resolve this issue

Now you have to realize that doing all these

what

they're doing is they're changing the input

for their 3D

runs and then they are getting and the

results are

coming out of a 3D multiphysics simulations

which are being

connected on the system level so they figure

out this

is not helping they try to decrease increase

the sand

concentration even that was not helping so

now then they

can dive deep to investigate the root cause

Since it

was a 3D they can see how and why this

things went wrong so they can see this 3D

visual

3D view of the system and here you can see

where you will see red they will see OK

because

of sand introduction because of the

sand introduction on

the steps the steps are highly eroded so it's

it's

irreversible damage which was done so by

changing the operating

condition it's not something we will improve in

it so that

they can verify if pump replacement can help

that by

just saying replacement what they're doing is

changing this pump

to an original geometry in this twin and as

soon

as it is it done it says that OK life

again went back so the operating conditions

are OK but

if you cannot install this new pump right

away because

of the location these things are installed so

operator can

do run an optimization analysis that what can

he do

in terms of operational settings which will

increase the lifetime

and they said they can run for 36 days and

this will help them identify the time needed

to come

up with a maintenance plan so this is

something which

we want to

you can create for any asset or any operation

system

level operation and the twin which is being

created is

platform agnostic and we partner with

multiple IoT platform and

you can get more information in our digital

twin sessions

and the industry best practice

booth out there

So another

aspect of digital transformation is additive

manufacturing so Ansys 00:14:32.950 --> 00:14:36.575 additive manufacturing solution can enable

engineers to quickly generate

printable design and avoid multiple build

failures and we have

a good design workflow which you can see for

topology

optimization as well as the additive

manufacturing workflow out there

which can help engineers to take this quickly

What we can see is this optimization this

optimization then

the optimized design can then go in be fed

into

our geometry processes to do some smart

selection to figure

out how you want to do anymore changes or

if you want to do smoothing to make it

it viable for manufacturing all those things

can be done

and it can be then used for

3D printing

You can see some testimonials from customers

in various press

releases where Ansys solution helped them

quite a bit in their either prognostic

health management

or creating some autonomous vehicles

For this next section of drilling and

production I

would like to just quickly talk about couple

of cases

So we have a good solutions for drilling

equipment if

you have a drill bit if you want to see

the analysis of drill bit or even if you want

to you do an erosion prediction on

those drill

to all that can be done and in fact we

have an existing drill bit template which is

a customized

workflow which can which usually automate the

design of complex

drill bit technology and it can be used

efficiently

for multiple scenarios

Similarly the Ansys solutions for drill

string insertion retrieval and

vibration are quite good and it will help you

understand

the dynamics of the drill string during

directional drilling or

avoid costly maintenance shutdowns

This is another example for perforation

creation and plugging where

Ansys solution of nonlinear geomechanics

material models or phase transition

models can help simulate well plugging

Again for each of those I am showing you

couple

of testimonials which you can read over and

learn more

about

In the next capability breakout section of

transport and storage

footage we have a comprehensive solution for

flow assurance challenges

be it regime modeling you want to do pressure

drop equipment

sizing erosion in pipelines or valve or pump

design you

can model all of them quite well with Ansys

solution

which will give you help you model

evaporation condensation

slurry flows hydrate formation slug flows even water

and sand management

so those solutions can help you resolve the

problems out

there

What we will see now is an example of Ansys

solution for erosion rate analysis due to

sand or particulate

transport

Ansys has very unique solution where we

have the

capability to not only determine

what is the erosion rate but we can even

couple

that with geometry deformation due to erosion

and that itself

will provide very accurate erosion

calculations and this is helpful

to capture these phenomena and do any kind of

troubleshooting

or maintenance management later

Along with Ansys and build solution for

particle flow modelling

we also have a very strong coupling solution

with Rocky

EDM now this coupling solution will provide

fast and accurate

settling prediction like in this case one can

see particle

behavior in cracks as well as in annular

region where

Rocky EDM computes parcel dynamics and

momentum source terms for

Ansys Fluent and fluent does the rest

The slides give you an idea of doing acoustic

noise

prediction and vibration that how it's

possible within Ansys

tools

where we have solutions for internal

propagating noise and external

noise in the far field

And this will help improve structural fatigue

life

for the assets for the customers

In the next few slides

you will see examples for Ansys solution

used

in resolving issues with equipment

reliability

First in the list is bolted connection so you

can

use

Ansys solutions for nonlinearities

and you can do

a multi stage analysis for better

understanding of connection behavior

you can figure out what is the deformation in

your

bolt you can do failure mode prediction in

assessment and

you can get an insight beyond your design

conditions

Similarly in pressure vessel you can use

Ansys linear and

nonlinear stress analysis or linearized

stress assessment analysis

to assess the code compliance of this

complex design

with less assumption we even have an app

pre built

into our App Store which has an automated

workflow

for the users

Corrosion is another failure mode which is

very relevant in

oil and gas industry Ansys solution can

model those electrochemical

reactions those electrochemical potentials

and can help you determine the

corrosion rate in this case you are seeing an

example

of a shell and tube heat exchanger and due to

this corrosion you can determine the life of

components

As mentioned earlier that due to emerging

technologies electrification is

quite important for oil and gas assets

and we're going to see some use cases on how

customer has been using Ansys solution for

such application

First in the list is oil well logging

applications

where Ansys solution help minimize

expensive physical testing by keeping

the cost for testing and control

They can help determine porosity water oil

saturation what kind

of obstacles are present like for example in

this ground

penetrating radar

What you analysis what you can see is the

solution

can help determine whether there is a metal

pipe down

there or a plastic pipe and can help

avoid any accidents

Cable modeling is also a big

need for the industry and we have a new

product

which is Ansys EMA3D Cable which is nothing

but

an automated streamline workflows it can

simulate the complex structures

it can do multi conductors in multi sealed

analysis and

it has good comprehensive cable library it's

very powerful and

it can be used to give value about

reliability and

lifetime or do electrical shorts or

overwhelmed voltage or even

bending stresses of this cables

Not only just that we have tools which will

help

in sensor design as well as determine the

correct position

for sensors for connecting this assets this

is not only

helpful for electrification but as well as

once you have

the connected assets you need them for

digital transformation

as well

The next section will briefly cover

Ansys solution for processing and refining

application

Fluidized modeling is quite important to

the industry and

Ansys solution can help prove hydrodynamics

in this large scale

builds or can help evaluate scale up and

optimize this

designs We have a comprehensive solution with

single phase to multiphysics to even system

level modeling capabilities

and this can be even coupled with third party

tools

to provide even more accurate solution

Moving forward you can use Ansys tools to get

an

end to end solution for your conversion

systems like furnaces

reformers boilers or even do a chemical

vapor deposition

analysis we have this capabilities where you

can

predict your pollutant like NOx or SOx

emission or even

soot

Modeling can be done which will help you

determine the

design for your equipment or even do

troubleshooting in the

existing design

Again as you see here our customers are using

these

solutions and they are saving money they are

improving their

processes

Last but not the least is safety and

compliance and

we will see some examples for this section in

following

slides

Oil and gas systems are full of mix of

explosive

flammable liquids

There are many components from different

vendors many regulation environmental

safety concern now you can perform the analysis

is like flaring

analysis as you see here to using Ansys

tools by

using our advanced multi phase and combustion

models you can

optimize your flare design to ensure clean

clean burning and

even determine thermal effects both of direct

interaction and radiant

heat load using fluid structure interaction

You want to do structural design code

checking then we

have those solutions

partnering with SDC verifier where we can

provide these tools

for structural code checking and this will

help streamline design

analysis and certification workflow

Another example is for well blowout

prevention containment or cleanup

process so Ansys solution

helps in design and make emergency

deployment more efficient or

even understand if there is a leak how that

oil

slick will be formed or do an analysis for

capping

stack or subset bloom modeling as well for

blowout preventers

I've shown you few examples in each of these

capability

breakout sections but we have lots more and

you can

learn more from using the following resources

This slide shows a list of these resources

from application

briefs to webinars short tips and tricks and

even customer

stories you can also log into Ansys Learning
