Petroleum Company Profile:
Welcome to Aban Singapore Pte. Ltd., a leading offshore
drilling services company in Asia catering to the
exploration and production needs of
the worldwide oil and gas industry.
Aban
Singapore Pte. Ltd., was incorporated on 18th
November 2005 under the Companies Act of Singapore
as a private limited company. In our first nine
months of operations, we acquired two operational
rigs and placed an order for a further rig.
In March 2007, we acquired Sinvest ASA, which at
that time owned three premium operational jack-up
rigs and had five premium jack-up rigs under
construction or on order, as well as an additional
jack-up rig and a deep water drill ship under
bareboat charter
Aban Singapore Pte. Ltd. primarily offers drilling
services to global oil and gas companies. All our
rigs are designed to provide increased efficiency in
our drilling services. Our rigs are equipped with
top-drive drilling systems, which enables them to
drill with drill pipes over 90 feet in length as
opposed to the standard pipes of 30 feet in length.
The top-drive drilling system also allows the drill
pipe to rotate while entering or exiting a well
hole, which increases safety and drilling
efficiency. All of our jack-up rigs (except for Aban
VII and Murmanskaya) are also installed with three
high-pressure mud pumps, thereby improving
efficiency and operational capability, and
increasing the popularity of our rigs with our
clients.
Our rigs are also capable of conducting directional
drilling operations, which enables us to carry out
drilling from various angles to reach multiple
geological targets from a single surface location.
We also have the ability to drill horizontal wells,
which can help to maximize production capacity, and
reduce overall development costs. This feature,
usually preferred by our clients, increases
operational versatility and maximizes our
efficiency. Understanding the drilling
processDrilling activity comprises the following
three phases, each of which our rigs and drilling
equipment are capable of undertaking:
Exploration, Appraisal, Development
Exploration
This process begins with drilling a down to a
pre-determined depth near the site where seismic
survey and other geological data indicate that the
oil or gas reservoir is located. This is established
using a drill bit, collar and drill pipe are placed
into the hole.
As and when the hole gets deeper, new sections (or
"joints") of drill pipe are added. Simultaneously,
drilling fluid, or "mud", is pumped down the hole to
lubricate the drill bit and remove cuttings during
the drilling process. This also controls well
pressure and ensures the integrity of the well bore.
Once the desired depth or stage is reached, the
drill bit, collar and drill pipe are removed (or
"tripped out") and a metal casing-pipe (or "casing")
is inserted into the hole to prevent it from
collapsing in on itself. Cement is then pumped down
into the cavity between the outside of the casing
and the wall of the hole in a process known as
"cementing". This helps to support and strengthen
the casing of exploration and development wells
against geological pressures and unexpected pressure
increases encountered during drilling. The cement is
allowed to harden and is then tested for hardness,
alignment and a proper seal.
A well is progressed in stages alternating between
drilling and running cement and casing. Appraisal
Rock cuttings from the drilling fluid are
periodically analyzed. When they reveal material
indicating the presence of oil or gas reservoir
rock, the drilling apparatus is removed from the
hole and more detailed tests are performed which
include
Well logging: Sensors are lowered into the hole to
take measurements of the rock formations
Drill-stem testing: Measuring the pressure in the
hole
Core sampling: Extracting and analyzing samples of
rock
We assist our clients with the collection of data
and materials, the installation of sensors and other
recording or sampling equipment, and other logging
activities to enable them to process and analyze
reservoir and well information, and plan drilling
operations accordingly. DevelopmentOnce the final
depth and location are reached, "well completion" is
carried out to allow oil to flow into the casing
under control. This requires the installation of
pipes and equipment required to enable safe and
efficient production from a well.
A perforating gun loaded with explosive charges is
introduced into the well to the production depth.
The detonations create perforations in the casing
through which oil can flow or gas can pass. After
the casing has been perforated, a small-diameter
pipe is inserted into the hole as a conduit for oil
and gas to flow up the well.
A device called a packer is run down the outside of
the pipe. When the packer is set at the production
level, it is expanded to form a seal around the
outside of the pipe. Finally, a multi-valved
structure called a Christmas tree is attached to the
top of the pipe and cemented to the top of the
casing. The Christmas tree allows the flow of oil or
gas from the well to be controlled. Once the well is
completed, the flow of oil into the well must be
induced and controlled.
This varies based on the kind of reservoir rock: For
limestone reservoir rock, acid is pumped down into
the well and out of the perforations. The acid
dissolves channels in the limestone that allow oil
to flow into the well.For sandstone reservoir rock,
a specially blended fluid containing proppants (such
as sand, walnut shells, and aluminium pellets) is
pumped down the well and out of the perforations.
The pressure from this fluid makes small fractures
in the sandstone that allow oil to flow into the
well, while the proppants hold these fractures open.
Once the oil begins to flow, the rig is removed from
the site and oil production equipment is installed
to extract the oil from the well. All of our rigs
are capable of installing requisite casing and other
pipes as well as delivering reservoir treatments
where required to increase the productivity of a
production well.
