P3 psi =
(P 1psi ) 2 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.

Formulas & Equations 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.

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
19
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) 12in. d 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: d 3.1416 6.25 6.545 (round to 6.5) 3 3
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
20
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 30
Rules of Thumb Estimating Temperature Drop Across a Choke or Orifice 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). Estimating Formula
Tdrop
Ph PL 1F atm
Where: Tdrop = Temperature drop (degrees) Ph PL
= Gas pressure before the choke (psi) = Gas pressure after the choke (psi)
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. Tdrop =
(1,000 500) 1F atm
= 33 x 1°F = 33°F temperature drop

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 1,000
Area of a Circle (in2) 0.7854 x D2 or π D2/4 or π R2 Where: D
= diameter (inches)
R
= radius (inches)

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.
