OVERVIEW

History

Croft Production Systems, Inc. started in 1986 as an

exploration, production, operation, and consulting company. Due to

a TEG explosion, Preston Croft designed and manufactured his first

passive dehydration unit (PDS). Initially, the unit was tested on his

personal production wells. Modifications and upgrades have been

made over the last 20 years. The original unit was designed to

address safety issues associated with TEG dehydrators. In the

early 1990’s it became more economical to use a PDS unit over a

TEG unit. And later, the PDS unit became necessary due to its

environmental benefits. Issues and concerns regarding the use of

TEG units (i.e., hazardous flames, emissions issues, toxic chemical

usage, etc.) eventually convinced Preston Croft to sell his

producing wells and go into business manufacturing and leasing

Passive Dehydration Systems to others.

Development

Initial leasing efforts were directed towards Preston Croft’s

friends and small operators as no one had previously used this

style of dehydration system for over 100 Mcfd. Growth was

obtained by explaining to companies and convincing operators in a

“grass roots” effort that the unit was safer, easier to operate,

environmentally friendly, and more economical than its TEG

counterpart. We were able to take an entity that had never before

been used in the Oil and Gas industry and establish that it worked

with small operators (under 1000 Mcfd). Because of our success,

operators began asking us to dehydrate gas for higher and higher

volumes. Even the EPA and Texas Commission on Environmental

Quality (TCEQ) acknowledges the tremendous benefit to the

environment that our systems have over traditional glycol units. We

currently manufacture for up to 20,000 Mcfd. CROFT has grown

from addressing only small operators to companies such as: XTO,

Anadarko, EP Energy, Chesapeake, Devon Energy, Hilcorp and

many more.

Overview 4

Market Overview

U.S. energy demands will continue to grow far into the future. There are over 600,000

producing onshore oil and gas wells in the United States. Most of these wells are clustered

in several Southwestern states: Texas, New Mexico, Oklahoma and Louisiana. These four

states account for 63% of U.S. producing wells. Texas, the number one oil and gas state,

accounts for 37% of producing wells. CROFT’s initial focus is Texas and Louisiana and will

selectively expand its services to other states.

Current Location of Units

CROFT is currently in 8 states with the highest concentration in the Gulf Coast area.

(PDS) Passive Dehydration System Raw natural gas requires dehydration in order to avoid the

formation of hydrates, reduce corrosion and meet sales

specifications before it is sent downstream. In today’s

competitive environment, evaluating performance and identifying

alternative methods for dehydration is becoming increasingly

important. Croft Production Systems, Inc. will properly size and

lease a dehydration system to meet your needs with

accompanying service included in the lease cost.

Wet gas flows upward through one or a series of vessels each

containing our specially formulated enviro-DRI desiccant. The

product absorbs the moisture, and dissolves into a brine solution

that is drained to the water storage on location. The by-product

is a non-hazardous material that can be retrieved by any

vacuum truck. The system is designed on a 30-60 day service

cycle schedule. CROFT recommends the design to have two or

more bottles in order to continuously dehydrate the gas while

one of the vessels is being serviced, avoiding shutdowns. This

state of the art modular design will effectively handle all

fluctuations of various well volumes and flow rates.

S (HRS) H2S Removal System The HRS unit is a great way to remove H2S from your system

without having to deal with permitting issues, emissions, and

fired vessels. This system was designed by CROFT to fully

utilize the capabilities of the H2S scavenger that it employs. In

standard bubble towers only a percentage of the scavenging

chemical is used up before needing to be replenished. With

CROFT’s atomization methods and static mixer implementa-

tion, CROFT can insure that the scavenger you are buying is

being fully utilized, decreasing the number of gallons required

to remove the H2S and ultimately….saving MONEY.

This system makes H2S scavenger more economically

attractive by shifting the cost breaking point before a

regenerative system is required (e.g. amine plant).

(FCS) Fuel-Gas Conditioning System The Fuel-Gas Conditioning System (FCS) is a skid-mounted,

hybrid unit that decreases the dewpoint and BTU of the gas by

several methods. This unique piece of equipment is designed

specifically for compressor fuel and instrumentation gas but is

not limited to small well streams. We have these systems in a

number of applications from polishing gas, to processing rig fuel,

or more commonly utilized at compressor gathering points.

CROFT’s FCS removes water and condensates to provide a

dehydrated and consistent BTU for utilization in high speed

engines and instrumentation.

(ACS) Ambient Cooling System High gas temperature can have a negative effect on the water

removal capabilities of a dehydration unit. The rule of thumb

being with every 20 degree increase in temperature, water

saturation capacity within the gas will double. Reducing the

temperature to a more manageable condition is essential to

effective dehydration and amine operation.

CROFT designs and manufactures ambient cooling systems

which passively cools gas; dropping out water and condensates

for separation and extraction. Our ACS quickly dissipates heat

with no moving parts and zero emissions. Additionally, when

coupled with our FCS or PDS systems, we can reduce the

amount of enviro-DRI used for dehydration.

(JTS) Joule Thomson System Croft Production Systems offers skid-mounted Joule Thomson

Systems designed to handle gas streams between 1 to 10

MMcfd. The JTS simultaneously reduces the water dewpoint of

gas, recovers valuable hydrocarbon liquids and lowers the BTU

of the gas stream to sales contract specifications or levels suited

for high-speed engines. These preassembled systems are

delivered ready to be installed on location and are contained on

a single skid.

Gas enters the JTS and travels through a series of heat

exchanger that pre-cool the gas. The gas then passes through

the JT valve, taking a pressure drop and cooling further. Liquid

fallout after the JT valve is collected in the cold separator and

sent to storage tanks. The cold gas then travels back through

the heat exchanger and exits the JTS.

(GSS) Gas Sweetening System Gas sweetening, also known as Amine gas treating, refers to the

process of removing H2S and CO2 from Natural Gas. Carbon

Dioxide and Hydrogen Sulfide are often found in natural gas

streams. CO2, when combined with water, will create carbonic

acid which is corrosive. H2S is an extremely toxic gas that is

very corrosive to equipment and must be removed.

CROFT designs and manufactures gas sweetening amine plants

with rates of up to 10 GPM of amine. Using the given

parameters for your particular gas stream we will design the

most efficient system to handle your specifications.

Full Service

Why Lease?

Croft Production Systems, Inc. mainly leases. The reason

behind leasing is to effectively match customer specifications to

the proper processing equipment. In the past, equipment was sold

to clients who, after a successful production term, moved the

equipment to another well site. The equipment was outside its

capability and did not preform to expectations of the client. CROFT

knows it takes years to build a reputation and seconds to lose it.

Leasing also affords the client the ability to scale up or down the

size of a unit as production changes. Equipment is released at the

end of a wells economic life keeping these assets from filling up

company supply yards. Croft Production Systems, Inc. designs,

manufactures and installs its own equipment.

What Full Service Means

CROFT is not only a full field service company but the office

staff provides full support as well. CROFT recognizes that field and

office personnel must communicate without any interruptions or

obstacles in order to give the best support to those who are

important; the Client. Listed below are some amenities provided

for Full Service Customers:

24 hour Regional Manager on Call

30 Day Mandatory Service

Field Reports shipped every month to well representatives

Confirmation calls before entering well site

Full Service 18

Invoicing

CROFT clients will only receive two invoices:

1. Equipment Lease

2. Chemical Cost

This philosophy is based upon the CEO’s 30 years experience

as an operator in dealing with vendors “nickel and diming” every

item. We don’t like adding fuel surcharges or equipment replace-

ment charges (i.e., pumps, valves, etc.) to client invoices.

Consistent Service Quality

CROFT spends hours training every employee in order to

sustain the Service Quality that CROFT is known for. CROFT Service

Technicians are put through a rigorous service program in order to

exceed the standard education but also to understand the

production site as a whole. In understanding the production site

from down hole to sales meter, the service technicians are able to

troubleshoot with more proficiency, complete field reports

thoroughly and make proper production recommendations to the

client. This service program is a continuous quality improvement

program which is ever evolving to give the customer a more

satisfying experience each time.

CROFT News
