WELL COMPLETIONS – SWELLABLE PACKERS
Swellable packers -monthly production up to 1,000 packers
Swellable packers are designed to reliably isolate production reservoir from the cased annulus
to prevent annular cross-flows, as well as to be used in other operations. Their dimensions and
type depend on the well completion size, the hole size, and the probability of cementing the
packoff zone. The elastomer length depends on the expected differential pressure during
production.
TATPROM-HOLDING Group has a unique fully integrated production facility for manufacturing
swellable packers starting from elastomer production and up to the final product. -

Hydraulic reamer shoe
Hydraulically actuated reamer shoe
The hydraulically actuated reamer shoe is designed to run 102-mm (4-inch) and 114-mm (4-1/2-inch)
casings with simultaneous reaming of non-stable wellbore intervals. The hydraulically actuated reamer shoe uses
the head pressure to ream at high shaft torque and specified rpm.
The packer can be set in vertical, deviated, and extended-reach wells to run liners and other well completion
assemblies. A casing can be fitted with several packers of this type.

INFLOW CONTROL DEVICES
Inflow Control Device
(ICD)
This choke valve limits the
reservoir fluid inflow from
high-permeability intervals
while balancing the
wellbore pressure.
Autonomous Inflow Control Device
(AICD)
Autonomous Inflow Control Valve
(AICV)
The negative effects of gas and water
breakthrough are controlled by the lowviscosity high-density fluid flow
(gas, water) creating differential
pressure inside the device (the Bernoulli
Effect), under the influence of which the
movable disk moves upward,
significantly limiting the capacity of the
AICD channels.
The autonomous inflow control valve
features a main inflow and a laminar
flow element (LFE). The
main inflow is fitted with a choke
valve, which position depends on the
pressure drop in the LFE. The
pressure drop is created by the LFE
and the turbulent flow element
(TFE).
Advantages:
Balances inflow;
Balances injection profile*;
Limits inflow of unwanted fluid (water, gas);
Controls of gas and water breakthrough*;
Balances wellbore pressure;
Increases long-term cumulative oil production;

SAND CONTROL
Direct-wire-wrapped screens
Direct-Wire-wrapped slotted screens are consist of ribbed perforated base
pipes with V-shaped wire wrapped around the base pipe. Wire
components are welded to each other, enabling the screen and the
basepipe to act as a single unit.
The filter mesh size varies from 50 to 2,000 microns.

*The basepipe flotation measures the strength of wire wrapping around the basepipe and is one of the crucial parameters that determines the
screen mechanical integrity.
THE WELL PRODUCTION PERIOD IN A GREAT EXTEND DEPENDS ON THE SCREEN SLOTS INTEGRITY DURING AND

✔ The Pre-packed screen comprises a perforated basepipe, a wirewrapped screen, gravel pack, and a jacket;
✔ The screen and the jacket are either welded or mechanically
attached to the basepipe;
✔ depending on the size the gravel pack can be 9- to 10.5-mm
(0.03- to 0.41-in) thick (gravel pack can be customized to the
Customer’s specs).

SAND CONTROL – Secondary completion with screens and ICD
✔ Inflow control devices will limit water and gas inflow into the wellbore;
✔ Recompletion with inflow control devices helps reactivate some of the inactive wells;
✔ Recompletion with screens reduces solids content of the produced fluid, thus extending ESP’s MTBF;
✔ Inflow control devices will increase cumulative oil production;
✔ Recompletion with inflow control devices improves zone isolation in operating wells, as well as total isolation of
high water cut intervals.

DIRECT-WIRE-WRAPPED SCREENS WITH INFLOW CONTROL DEVICES AND TRACER SYSTEMS
Direct-wire-wrapped slotted screens are ribbed perforated basepipes shrink-wrapped with V-shaped wire.
Screen components are welded to each other, enabling the screen and the basepipe to act as a single unit.
Direct-wire-wrapped screens can be fitted with inflow control devices, designed to balance injectivity (inflow)
of a well. They also come equipped with sliding sleeves that close the slots in case of a water (gas)
breakthrough to totally isolate the screened section or during a frac job. At the request of the Customer
direct-wire-wrapped screens can be fitted with a tracer system.
