The document outlines primary, secondary, and tertiary recovery methods and production systems including artificial lift and gas lift. Finally, it covers well servicing, maintenance, and interventions.
First stage: limestone chunks are transported by special vehicles to raw materials bin, after the forklift / artificial then delivered to the jaw crusher for crushing by forklift or man.
Second stage: Crushed limestone is lift to the hopper by hoist, then transported by feeder.
Third stage: Qualified products after the grinding process enter the collector through classifier and pipe. The discharged powder is finished product. Unqualified powder cannot pass the classifier, and falls back to the main unit.
Fourth stage: The purified air stream flows into the blower through pipe above the collector. The air duct is circular, it is negative pressure pipe flow, except for the grinding chamber and blower, so indoor air conditions are good.

3. Differences Open/Cased Hole
• Junk more hazardous in cased hole
• Few pieces can foul tool/ slips on packer
• Small clearances increases chance of
sticking due to sand or junk.
• Can’t wall off as in open hole
• Labor bound W/ tubing/ pumping,
rotating capacity/ non viscous fluid.
8-2-2000 3
4. Mud Stuck Tubing
• Most common WO fishing jobs
are stuck tubing
• Caused by de-hydrated mud o
sand in annulus
• Best method is to free point and
back-off, circulate out,
screw back together, work
the pipe, free point, etc.

Shortcut to most common.mpg.lnk
6. Stuck Tubing
• Other causes of stuck tubing are
collapsed casing or a frozen
packer.
• Permanent packers can be milled over
and retrieved
• Retrievable’s are usually releasable/ no
sand on top
• Retrievable’s are difficult to mill,made of
premium alloy steel
8-2-2000 6
7. Retrieving Packers
• Tubing free to packer, string shot/free
• No success, cut tubing 1/2 Jt. above Pkr.
• Either jar free or mill over and retrieve
• Stuck long way from packer, cannot jar
• Out side wash down cutter on washpipe
8-2-2000 7
8. Washover Operations/Cased Hole
Performed in cased hole to:
• Wash sand or dehydrated mud from
around completion string
• Mill over packers/other completion tools
• Mill junk from the outside of a fish
• Make external cuts on completion string

release from collar connected or
bottle neck pipe.
• This is achieved without any left hand
rotation, jay joints, shear pins, or
pump manipulation.

Cutter The “DH” external cutter is made up of
three sections:
• The overshot section
• The drive section
• The cutting section
8-2-2000 12
14. Knifes are Protected
• The cutting section cannot be damaged by
heavy loads placed on the overshot
section.
• The load on the knifes is fixed by the way
the cutter is designed.
• By protecting the cutting section, long and
heavy loads can be recovered.

18. Procedure to Release Cutter
• To release the cutter, slowly rotate the
pipe while raising it simultaneously.
• Pick up until the cutter overshot engages
the collar,taking a slight up strain
• The cutter will jump off the collar
8-2-2000 18
19. Procedure To Cut Pipe
• Pick up on string without rotation, until
cutter engages the coupling
• Take recommended pull load.
• Rotate to the right. Cut is made in one to
five minutes.

21. Bowen External Cutter
• A two trip cutter
• Fish must have been washed over first to
insure the cutter will go
• Tool is run on bottom of washpipe
• Cut one joint above lowest point washed to
8-2-2000 21
22. Dressing the Cutter
• Select proper catching assembly
• Spring Dog; square shouldered pipe
• Ratchet pawl; bottle neck pipe
• Assemble cutter Per Bowen Manuel
• Wedge knifes in slots with soft line
8-2-2000 22
23. Cutting Procedures
• Circulate at top of fish, record torque
and drag parameters.
• Rotate as little as possible while getting
over fish.
• Take care not to break the knives while
picking up to pull the slips.
8-2-2000 23
24. Cutting Procedures
• Slowly raise the string until the ratchet
pawls engage the tool joint
• Upward strain will cause the mainspring
to compress snapping the shear pin.
• The main spring will fed the knives
automatically with even cutting
pressure.
8-2-2000 24
25. Cutting Procedure
• Thereafter, the cut is made by rotating
the string slowly to the right.
• Weight gain and loss of torque indicate
that the cut is made.
• The spring dog or ratchet pawl will retain
the cut off section.
• Do not rotate while POH
8-2-2000 25
32. Bowen Hydraulic External Cutter
• It is hydraulically operated to cut tubing
or drill pipe externally.
• Knives are fed entirely by pump
pressure.
• Will cut any where on the tube,doesn’t
have to be under a collar.
8-2-2000 32
33. Operation Procedures
• At cutting depth, begin pumping slowly with the
fill up line and standpipe valves open.
• Slowly close the fill up line until 150 P.S.I. is
reached to shear the shear pins.
• Bleed the standpipe pressure off, begin rotating
at 15 to 25 R.P.M.’s.
• Slowly bring pump pressure up until torque is
encountered.
8-2-2000 33
34. Operating Procedures
• The 6-1/16² O.D. tool requires only 40
P S I to make a cut.
• A rough chattering action followed by
the smoothing of the torque will
signal when the cut is made.
• Bring the cut section out and strip it
from the washpipe.
8-2-2000 34
40. Inside Mechanical Cutter
• Used to cut casing that can be retrieved
prior to running a casing patch.
• Rotation to the right allows the friction
assembly to unscrew from the mandrel.
• Further lowering permits the cone to be
driven through the slips, thereby
anchoring the tool.
8-2-2000 40
41. Cutter Operation
• As the slips firmly engage, the wedge block
forces the knives outward.
• This action is continued until the pipe is cut
as indicated by either increased or
decreased torque.
• When the cut is completed, the pipe is
raised, the slips disengage, the knives
retract, and the friction assembly
returns automatically to the run in
position.
8-2-2000 41
42. Unique Feature of Tool
• A unique feature or the tool is the
“automatic nut” which allows the
resetting and disengaging of the tool any
number of times without P.O.H.
• A bumper sub should be run one drill collar
up to set a predetermined amount of
weight on the cutter to avoid breaking
the knives.

48. Packer Job Preparation
• Schematic and date of well setting
• Production string details
• Permanent or releasable, make, model,etc.
• Releasing Procedures
• Special retrieving tools
• Blast joints, x-nipples, ball valves, etc.
8-2-2000 48
49. Assembly Checklist
• Insure shear pins are in place, note the
number and shear values.
• Ensure enough working space is
available between the rotary shoe
and the attachment tool.
• Make sure the inside diameter of the
rotary shoe is large enough to
pass over the catching device.
8-2-2000 49
50. Assembly Checklist
• Ensure there is enough washpipe above
the (JB) bushing to cover the fish,plus
the inner mandrel and the fishing tool
attachments.
• If a spear is used, make sure the grapple
is locked in the catch position with a
pin down in the gap area.
8-2-2000 50
51. Running Procedure
• TIH, do not engage fish yet.
• Break circulation slowly and record all
parameters.
• Make sure enough kelly is available above
the rotary to engage fish, release from
the (JB) bushing and mill over the
entire fish. (Disregard if top drive is available)
8-2-2000 51
52. Releasing Instructions
• Slowly lower the work string and make
engagement to the fish.
• Pick up to shear the pins; about 5,000 lbs.
• Hold 1/4 round left hand torque (at the tool)
while slacking off approximately one
foot. This should clear the lugs from the
spline.
• Begin milling operations with 1 to 2,000#
wt. to groove the top of packer.
8-2-2000 52
53. Milling Rates:Surface Feet per Minute
Crushed carbide mills = 150 to 200 S.F.P.M.
Carbide insert mills = 150 to 300 S.F.P.M.
Surface Feet Per Minute = Mill Diameter X R.P.M. X .262
Example: Mill Dia. = 4.5” ; RPM. = 120 ; What is the SFPM ?
4.5” Mill X 120 RPM X .262 = 142 SFPM
R.P.M. = SFPM Dia. Mill X 3.82
Example: 142 SFPM 4.5” Mill X 3.82 = 120 RPM.
8-2-2000 53
54. Parameters
• Max.Wt. = 1,000# per OD inch of mill
• Mill with torque; not weight
• Set torque limit; weakest connection
• A.V. of 150/200 Ft./min.
8-2-2000 54
55. Observations
• Should space rings begin to turn; dry drill
with maximum drill collar weight until
they lock up and torque is regained
• Run high viscosity sweep’s
• Check cuttings often for signs
• 8 rd. tubing will make up 1”/1,000
8-2-2000 55
56. Shoe Design
• Important, custom build to specific needs
• Qualified carbide welder a must
• Factory made crown larger than tube
• Allows for counter boring for larger rod
• Dress crown OD to casing drift size
• Packer type to be milled determines ID
8-2-2000 56
57. Shoe ID Size
• For permanent packers dress the ID so
the mandrel will be OD fishable
after burn over
• For dual packers and retrievable
types,dress the shoe to cut as little as
possible off the packer, but still cut
the slips to effect release.
