Principles of safe and secure disposal boreholes and wells

I. Principles of secure attachment boreholes and wells

A) or borehole probe must be fitted to the mouth of the corresponding pressure
dimension allowing mastering the anticipated pressure
speeches. This device must be protected against damage and
secured against manipulation by unauthorized persons.

B) The probe must be also equipped with a column of filling pipes sufficient length to allow
its safe anesthesia.

C) ensure the project boreholes and wells must also address the protection of open
horizon.

II. Principles of safe disposal boreholes and wells

A) Each open horizon, and each section of perforated casing in place
open horizon isolating the bridge.

B) Checks for cementing the annulus and docementují
loose or poorly cemented annulus segments.

C) wellhead or probes is collected and disposed of in accordance with paragraph 6 of Annex no. 6
hereto.

D) If nezacementovaná be pulled out of the casing column and allows
if state or borehole probe, opens the casing column in the largest
safely reach deep and pulled out.

E) Location disconnection casing column is collected on the bridge cement
length such that the bridge intervened at least 30 m in the column casing above and below the site
disconnection; in the case of high-pressure isolation originally horizon
above the disconnection casing build a mechanical bridge over it
cement bridge with a length of at least 30 m.
Appendix 6


Minimum technical requirements for the safe and secure disposal wells and probes


First Isolation horizons in nezapaženém borehole

Insulation horizon nezapaženém drilling is performed with cement bridge, with a length
least 50 m above the horizon 30 m below the horizon (Fig. 1.1).

Second Isolation horizons in the hole or perforated lagged probe

Each perforation casing is recovered by pressure cementing his head
bridge at least 30 m above the horizon (Fig. 2.1). When it is used in the cementing packer
carburizing (retainer) may be the head of a cement bridge only 20 m above
cementation packers (Fig. 2.2).

For harsh conditions lagged borehole or probe that would impede or
guarantee the quality insulation horizon using cement
bridge, and in the case of isolation of the horizon, the initial pressure was higher than

Hydrostatic pressure, above the perforated interval settles mechanical
bridge and stand over him with a cement bridge with a length of 30 m (Fig.
2.3).

Third Nezapaženého isolation or partially zapaženého or borehole probe

If borehole probe or partially lagged, build a cement bridge
from the bottom of the column casing at least a length of 50 m above the heel, and 30 m below the heel
casing (Fig. 3.1). When using a mechanical bridge, length can be shortened
cement bridge up to 30 m over head mechanical bridge
(Fig. 3.2).

Fourth Isolation heads liner and casing jobs disconnection

Head liner and instead releasing casings are isolated cementation of the bridge
length of 60 m, which is located at least 30 m in each column
casing above and below the head liner or place of disconnection (FIG. 4.1).

If instead of releasing the nezapaženém borehole interval, put in place a cement bridge
cuts of at least 30 m above cuts and 30 m below
place and cut the heel of the casing column bridge of at least 50
m above the heel and the heel 30 m casing (fig. 4.2).

When using a mechanical bridge established over the head liner, just above it
build a cement bridge with a length of 30 m (Figure 4.3).

Fifth Isolation of the annulus

Nezacementované or poorly cemented annulus
must be insulated. Nezacementované for disposal of the casing column applies
Part II of Annex no. 5 hereto. Nezapažený interval borehole or
probe is isolated under Section 4

In case the casing do not pull loose isolated annulus through
place disconnection casing or via a. A window situated as low as possible
head cement in the annulus. Above the window open or stands
pressure cement bridge, and when the pressure cement bridge
not build, build a cement bridge, with the head of at least 30 m above
point of disconnection or window.

6th Isolation and disposal wellhead or probe beneath the surface

Wellhead isolation or probe beneath the surface is done using a cement
bridge with a length of 30 m. The soil around the mouth of the probe to the clearance
depth of 1.8 meters below ground level. At a depth of at least 1.5 m from the surface
surrounding terrain is cut all the column casing. Casing is Doli
cement paste and after hardening cement the well head sealable
welded steel plates with min. thickness of 10 mm on each column casing.

Over the last welded steel plate is fabricated concrete slab
thickness of less than 0.2 mA wellhead and probes are designated according to § 71d;
it is considered borehole probe or be liquidated (Fig. 6.1).
