Lubricate & Bleed Calculations
Simplified Equation for Lubrication
P3 psi =

P 2 psi
Where:
P1 = Original shut in pressure
P2 = Pressure increase due to pumping lubricating
fluid into the wellbore.
P3 = pressure to bleed down after adding the
hydrostatic of the lubricating fluid
Procedure:
1. Select a working pressure range. For example,
Pw = 50 - 100 psi.
2. Pump lubricating fluid through the kill line to
increase the casing pressure by the working
pressure, so that P2 = P1 + PW.
3. Allow the pressure to stabilize. The pressure may
drop by a substantial amount.
4. Calculate the pressure (P3) to bleed down to by
using the formula above.
5. Repeat steps 2 through 4 until all the gas is
lubricated out of the well.

Accumulator Sizing
API Minimum Requirements
100% (S.F.= 1) of fluid volume required to close and
hold closed all preventers and open an HCR valve
and have a system pressure of 200 psi above minimum
recommended precharge pressure remaining on the
accumulator with pumps off.
Standard Recommendation
150% (S.F.= 1.5) of fluid volume required to close and
hold closed all preventers and open an HCR valve
and have 1,200 psi system pressure remaining on the
accumulator with pumps off.
Fluid Volume Required (Volreqd)
Volreq = S.F. x (CloseVolannular + CloseVolbop1

+ CloseVolbop4 + OpenVolhcr)

Accumulator Sizing, continued
Accumulator Volume Required
Usable hydraulic fluid for operation of blowout preventer
equipment is affected by system pressure and nitrogen
precharge. If the nitrogen precharge is at the correct
(recommended) precharge, multiply the sizing factor from the
table below times the fluid volume required to operate a
specified number of BOP functions (Volreq) will provide the
required total accumulator volume.

* Based on minimum system pressure of 200 psi over precharge.

All precharge pressures should be in compliance with API 16D.
Precharge Pressure: The accumulator bottles filled with only
precharge gas at its initial pressure and ambient temperature. The
precharge pressure should be specified with a temperature.
Precharge pressure is not to exceed the working pressure of the
accumulator. Any precharge pressure less than the working
pressure of the accumulator may be used as long as the
functional requirements of pressure and volume and minimum
design factors are satisfied.
Accumulator Volume Example
If the total fluid required for a BOP stack is 33 gallons, including
the safety factor, and the accumulator has an operating
pressure of 3,000 psi with a 1,000 psi minimum precharge, the
accumulator volume required is 33 gallons times the size factor
of 2, or 66 gallons.

Rules of Thumb
Tripping Rules of Thumb
Ideally, drillers would like to keep bottomhole
hydrostatic pressure constant during the trip out (POOH)
and the trip in (RIH). However, this is impossible from the
operational standpoint because of swab and surge
pressures. Most tripping rules-of-thumb are closely
associated with maintaining a safe hydrostatic
overbalance that neither causes a kick nor lost
circulation.
Slug Mud Weight Rule of Thumb
Slug mud weight is generally one ppg higher than the
hole mud weight, with the objective being to
unbalance the DP/annulus U-tube by enough to pull
dry pipe. The condition of the mud, related to drill
solids, and/or the mud weight range could influence
the driller to accept less than one ppg.
Rules of Thumb

Stuck Pipe
The causes of stuck pipe are broadly classified as
differential or mechanical, and good monitoring and
operating practices will minimize both types of pipe
sticking. Differential sticking is caused by mud pressure
overbalance and is influenced by drilling practices, type
mud solids, permeability, bottom-hole assembly
clearance, coefficient of friction and the lubricating
characteristics of mud. Mechanical sticking is caused by
deterioration of hole stability (shale problems, hole
cleaning, etc.) and/or directional (crooked-hole)
problems.
Rule of Thumb for Differentially Stuck Pipe
The estimated force required to pull free is equal to
the contact force per unit length, times the length of
pipe in contact with permeable formation times the
coefficient of friction. This estimate tends to be more
accurate in a straight hole than in a directional well.
Estimating Formula for Differential Sticking
Fdiff = K (P) Area
Where:
K
(P)
= Sticking coefficient (0.2 water base mud)
= Differential pressure (psi)
d
= Diameter (inches)
L
= Permeable zone length (feet)
Area = Contact area (inches 2)

Area = L  
  

 ft   3 
(assume ⅓ of the drill collar circumference is buried)
Circumference =  x Diameter
Conclusion: Force to pull free increases as the length of pipe
in contact with permeable formation increases, and as the
coefficient of friction between pipe and wall increases.
Example
Given 6 ¼" DC:

P = 200 psi (approx. 0.5 ppg overbalance at 8,000 ft)
L = 200 ft (of permeable zone)
Fdiff = 0.2 x 200psi x 200ft x 12in./ft x 6.5in. = 624,000lbs

Rules of Thumb
Free Point and Stretch Estimates
When the drill string is stuck, the free point method can
be used to estimate the amount of free pipe in the hole.
Begin by pulling on the pipe with an initial force (Fi) that
is at least 1,000 pounds more than the hanging weight
of the string, and make a reference mark on the string.
Increase the pull by increments (for example, 5,000 lbs)
to final force (Ff) to determine a measurable stretch.
Mark the string again, measure the distance between
the marks and record as the stretch (S) in inches. Record
the difference between Ff and Fi as the pull increment
(PI). The amount of free pipe (L) in 1,000’s of feet below
the rotary can then be estimated. These estimates tend
to be more accurate in straight holes than in directional
wells.
Estimating Formula
The formula for free pipe length L is:
L = 1.9635  S 
OD 2  ID 2
PI
The formula for pipe stretch S is:
S=
Pl  L
2
2
1.9635  (OD  ID )
Where:
L
= Length of free pipe (1,000s ft)
S
= Stretch (inches)
OD = OD of the pipe (inches)
ID
Pl
= ID of the pipe (inches)
= Pull increment (1,000s lbs) = Ff - Fi
Example
Given:
Drillpipe size = 5", 19.5 lb/ft
OD = 5"
ID = 4.276"
Fi = 5,000 lb
Ff = 35,000 lb
S = 12"
Calculate:
PI = 35 – 5 = 30
25  18.284
L = 1.9635  12 
= 5.27 thousand feet

Estimating Temperature Drop

Rule of Thumb
The temperature drop across a choke or orifice is
about one degree Fahrenheit (F) per each pressure
drop of one atmosphere (rounded at 15 psi).

Where:
Tdrop = Temperature drop (degrees)

atm = Atmospheric pressure (15 psi)
Example
Calculate temperature drop if the gas pressure is
reduced from 1,000 psi to 500 psi across a choke.

Estimating Gas Well Flow Rates
Rule of Thumb
The approximate flow rate (in mmscfd) of a gas well
through a blowdown line choke can be estimated by
multiplying 24 hours/day, times the tubing pressure
plus 15, times the square of the choke size in inches
and divide by 1,000.
Estimating Formula
Q=
24 x (PL  15) x (Dch)2
1,000
Where:
Q = Flowrate (mmscfd)
PL = Pressure upstream of choke (psi)
Dch = Choke size (inches)
Example
Calculate the estimated flowrate of a gas well, given
that tubing pressure is 3,500 psi, and choke size is 1/4.
Q=
24 x (3,500  15) x (0.25)2
= 5.273 mmscfd

Rules of Thumb
Pipe Elongation Due to Temperature
Since the well has higher temperatures than the air
above ground, an elongation will take place.
Rule of Thumb
Pipe will elongate about 0.83 inches, per 100 feet of
length, per 100 degree F increase in temperature.
Knowing the surface temperature and the average
temperature of the well, the elongation can be
estimated.
Note:
Elongation (stretch) is also caused by the
hanging weight of pipe.
