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.

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
