1 W. | e. Equipment Catalogue | Slickline ToolsSlickline ToolsStem ForceTo calculate the force to be overcome to enter the well use the following formula, remember this will give you the balance point, your weight needs to exceed this = Pressure x AreaForce - what we have to exceed using stem barPressure the Well Head PressureArea cross sectional area of the wireline being used (see table below)To calculate standard stem weight per foot use the formula: PressurePT = PA + PHPT - Pressure (total)PA - Pressure (Applied) - WHP or Annulus observed on a tree gaugePH - Pressure (Hydrostatic) - result of fluid gradient and depthHydrostatic pressure = Fg (fluid gradient - psi/ft) x TVD (true vertical depth - feet)Standard fluid gradient Fg (psi/ft) = lbs/gal x to standard fluid gradient x 83 SIZE AND CROSS SECTION AREAC ross Section 3/16 7/32 1/4 5/16 wireline Operations - Slickline CalculationsWIRELINE OPERATIONS: SLICKLINE CALCULATIONSw.

This should be bent to form a 90 deg angle then twisted around itself.

Equipment Catalogue | Slickline ToolsSlickline ToolsH2S and Partial Pressure CalculationsThe damage to the wire is not caused directly by the % of CO2 or H2S but is more a function of the Partial Pressure To determine the Partial Pressure for H2S:PH2S = PPM H2S in gas x BHP/1,000,000 Example: In a well with 3ppm H2S and a BHP of 6,000psiPH2S = 3 x 6,000/1,000,000PH2S = 18,000/1,000,000PH2S = NACE regulations a PH2S of or greater would determine that you need to choose an alloy wire or seek to protect/inhibit you wire (Alloy wire is by far the safest option).To determine the Partial Pressure for CO2:PCO2 = CO2 % x BHP/100 Example: In a well with 3% CO2 and a BHP of 2,000psi PCO2 = 3(%) x 2000/100 PCO2 = 3(%) x 20 PCO2 = 60psiUnder NACE regulations a PCO2 of 32psi or greater would determine that you need to choose an alloy wire or seek to protect/inhibit you wire (Alloy wire is by far the safest option).
