Dawson Geophysical Company, a Texas corporation, is a leading provider of North
America onshore seismic data acquisition services with operations throughout
the continental United States (“U.S.”) and Canada. We acquire and
process 2-D, 3-D and multi-component seismic data for our clients, ranging from
major oil and gas companies to independent oil and gas operators as well as
providers of multi-client data libraries. Our principal business office is located
at 508 West Wall, Suite 800, Midland, Texas 79701 (Telephone: 432-684-3000),
and our internet address is www.dawson3d.com.
We provide our seismic data acquisition services primarily to onshore oil and
natural gas exploration and development companies for use in the onshore drilling
and production of oil and natural gas in the continental U.S. and Canada as
well as providers of multi-client data libraries. The main factors influencing
demand for seismic data acquisition services in our industry are the level of
drilling activity by oil and natural gas companies and the sizes of such companies’
exploration and development budgets, which, in turn, depend largely on current
and anticipated future crude oil and natural gas prices and depletion rates
of the companies’ oil and natural gas reserves.
We acquire geophysical data using the latest in 3-D seismic survey techniques.
We introduce acoustic energy into the ground by using vibration equipment or
dynamite detonation, depending on the surface terrain, area of operation, and
subsurface requirements. The reflected energy, or echoes, are received through
geophones, converted into a digital signal at a multi-channel recording unit,
and then transmitted to a central recording vehicle. Subsurface requirements
dictate the number of channels necessary to perform our services. We generally
use thousands of recording channels in our seismic surveys. Additional recording
channels enhance the resolution of the seismic survey through increased imaging
analysis and provide improved operational efficiencies for our clients. With
our state-of-the-art seismic equipment, including computer technology and multiple
channels, we acquire, on a cost effective basis, immense volumes of seismic
data that, when processed and interpreted, produce precise images of the earth’s
subsurface. Our clients then use our seismic data to generate 3-D geologic models
that help reduce drilling risks, finding and development costs and improve recovery
rates from existing fields.
In addition to conventional 2-D and 3-D seismic surveys, we provide what the
industry refers to as multi-component seismic data surveys. Multi-component
surveys involve the recording of alternative seismic waves known as shear waves.
Shear waves can be recorded as wave conversion of conventional energy sources
(3-C converted waves) or from horizontal vibrator energy source units (shear
wave vibrators). Multi-component data are utilized in further analysis of subsurface
rock type, fabric and reservoir characterization. We own equipment required
for onshore multi-component surveys. The majority of the projects in Canada
require multi-component recording equipment. We have operated one to two multi-component
equipped crews in the U.S. routinely over the past few years. The use of multi-component
seismic data could increase in North America over the next few years if industry
conditions improve and potentially require capital expenditures for additional
equipment.
In recent years, we have begun providing surface-recorded microseismic services
utilizing equipment we currently own. Microseismic monitoring is used by clients
who use hydraulic fracturing to extract hydrocarbon deposits to monitor their
hydraulic fracturing operations. In addition, seismic data are sometimes utilized
in unconventional reservoirs to identify geo-hazards (such as subsurface faults)
for drilling purposes, aid in geo-steering of a horizontal well bore and rock
property identification for high grading of well locations and hydraulic fracturing.
The majority of our current activity is in areas of unconventional reservoirs.
Technological advances in seismic equipment and computing allow the seismic
industry to acquire and process, on a cost-effective basis, immense volumes
of seismic data which produce precise images of the earth’s subsurface.
The latest accepted method of seismic data acquisition, processing, and the
subsequent interpretation of the processed data is the 3-D seismic method. Geophysicists
use computer workstations to interpret 3-D data volumes, identify subsurface
anomalies, and generate a geologic model of subsurface features. In contrast
with the 3-D method, the 2-D method involves the collection of seismic data
in a linear fashion, thus generating a single plane of subsurface seismic data.
3-D seismic data are used in the exploration and development of new reserves
and enable oil and natural gas companies to better delineate existing fields
and to augment their reservoir management techniques. Benefits of incorporating
high resolution 3-D seismic surveys into exploration and development programs
include reducing drilling risk, decreasing oil and natural gas finding costs,
and increasing the efficiencies of reservoir location, delineation, and management.
In order to meet the requirements necessary to fully realize the benefits of
3-D seismic data, there is an increasing demand for improved data quality with
greater subsurface resolution.
In recent years, we have experienced continued increases in recording channel
capacity on a per crew or project basis. This increase in channel count demand
is driven by client needs and is necessary in order to produce higher resolution
images, increase crew efficiencies and undertake larger scale projects. Due
to the increase in demand for higher channel counts, we have continued our investments
in additional channels. In response to project-based channel requirements, we
routinely deploy a variable number of channels on a variable number of crews
in an effort to maximize asset utilization and meet client needs. While the
number of recording systems we own may exceed the number utilized in the field
at any given time, we maintain the excess equipment to provide additional operational
flexibility and to allow us to quickly deploy additional recording channels
and energy source units as needed to respond to client demand and desire for
improved data quality with greater subsurface images. We believe we will realize
the benefit of increased channel counts and flexibility of deployment through
increased crew efficiencies, higher revenues and margins with improved conditions.
Since 2011, we have purchased or leased a significant number of cable-less
recording channels. We have utilized this equipment primarily as stand-alone
recording systems, but on occasion we have utilized it in conjunction with our
cable-based systems. As a result of the introduction of cable-less recording
systems, we have realized increased crew efficiencies and increased revenue
on projects using this equipment. We believe we will experience continued demand
for cable-less recording systems in the future. While we have replaced cable-based
recording equipment with cable-less equipment on certain crews, the cable-based
recording equipment continues to be deployed on existing crews.
