Wait and Weight method on Directional Wells

 Wait and Weight method on Directional Wells

ww_on_directional_top01

During drilling operations on oil wells, there may to occur the inflow of formation fluids into the well, which is an undesirable condition. The driller should detect such events and shut-in the well immediately and to record informations corresponding to stabilization of pressures SIDPP (Shut-in Drillpipe Pressure) and SICP (Shut-in Casing Pressure) and the volume gain.

There are two methods more used to well control when the drill string (drill bit) is in the bottom of borehole (normally on drilling when reaches a formation with pressure bigger relative to the bottom hole pressure): The Driller’s Method and the Wait and Weight Method (also named Engineer ‘s Method).

The Driller’s Method is performed with two circulations. The first circulation with the original fluid to circulate the influx out of well and the second circulation to fill the borehole with a new fluid. This method can be started immediately after shut-in the well.

The Wait and Weight Method is performed just with a single circulation with the new fluid, but is necessary to wait a lag time until to prepare the new fluid to start the method.

The choice of the method

The choice between these two methods is a controversial question among professionals of oil & gas, but if the rig has already the new fluid available to control the well (the hydrostatic pressure of the new fluid is equivalent to the formation pressure), the Wait and Weight method is aplied and the control will be just with a single circulation in two steps:

Wait and Weight Method

Step 1

Replacing the original fluid in the drill string with the new fluid circulating until the drill bit. Start pump and bring the pump speed until the slow circulation rate, keeping the circulating pressure according the table “Pressure versus Pumped Strokes”, starting with the Initial Circulating Pressure (ICP) and ending with the Final Circulating Pressure (FCP).

ICP = SIDPP + Circulating Pressure @ Slow Circulating Rate (recorded previously).

FCP = Pressure(@ scr) x New Fluid Density / Original Fluid Density

Vertical Wells

On vertical section, the rate “pressure drop / stroke” is constant and the calculations can be made in 10 steps.

ww_table

ww_graph_vert

Directional Wells

On deviated section, starting on Kick-Off Point (KOP), the rate “pressure drop / stroke” is not constant. The calculations will consider the steps by 100 strokes each.

ww_direc_calcs

ww_dir_table_calcs

ww_graph_dir2

Step 2

Continue the circulation with the new fluid to fill the all annular until the surface keeping the circulating pressure constant equal to FCP – Final Circulating Pressure.

Operational Limits

It is very important to monitor operational limits during the circulation to avoid fracture of the formation, usually at the shoe depth of the last casing.

The advantage of the “Wait and Weight” method is to provide a lower resultant pressure at the shoe depth before the gas reaches the shoe depth, that is, when the new fluid passes through the drill bit, increasing the hydrostatic pressure in the annulus before of the gas to reach the shoe depth.

ww_limits

Conclusion

The Wait and Weight method is advantageous when the rig has already the new fluid available to immediate circulation. Normally the new fluid need a lag time to be prepared. (1) On well closed, an influx of gas is moving up continuously and pressurizing the borehole all the time. (2) The calculations to control directional wells are relatively complex.

If it is not possible for the new fluid to reach the annulus before the gas reaches the shoe depth, due to (1) the lag time to prepare the new fluid or (2) the volume of the drill string is greater than the volume of the annulus above the gas until the shoe depth or (3) the difficulty to calculations on directional wells or (4) formations with low fracture pressure on deepwater for example, it is recommended choose the “Driller’s Method” to start immediately after the shut-in the well, holding the circulation pressure equal to Initial Circulating Pressure until the circulation of the total volume of the annulus and to replace the fluid only in the second circulation of this method.

I hope that this simple explanation about the Wait and Wait method on directional wells helps on choicing the method most efficient.

MPD Simulator for iPhone and iPad 

MPD Simulator for iPhone, iPod touch and iPad 

MPD Simulator

Available_on_the_App_Store_Badge_US_UK_135x40_0824

This app is designed for both iPhone and iPad.

This application provides practical simulations of the Dynamic Well Control on the Managed Pressure Drilling (MPD) operations in the oil field services.

With Managed Pressure Drilling (MPD), when kicks occur, they are typically smaller, contained more quickly, and, in some cases, they may be circulated out through MPD equipment without drilling or circulation interruption.

This simulator is the new project based on the Drilling Simulator 2 available on our portfolio on the App Store, but specifically for dynamic well control on onshore and offshore operations (deepwater).

MPD System on this simulator:

1. RCD – Rotating Control Device
2. Annular Preventer (or Drill String Isolation Tool – DSIT)
3. Automated Choke for CBHP (Constant Bottom Hole Pressure), Constant Drill Pipe Pressure and Constant Choke Pressure.
4. RPD – Rig Pump Diverter
5. BPP – BackPressure Pump

Additional features:
1. Driller Interface based on Pressure Gauge, Weight Indicator, Rotary Torque gauge and Geolograph.
2. Choke Interface based on Hydraulic Choke Digital Panel.
3. Graph in full screen (with background color in black or white) for analysis.
4. Special screen layout optimised for iPhones 6 / Plus and iPad Pro
5. Auto/Manual Control on MPD Choke ONLY.
Note: For well control based on conventional rig choke panel, please buy the “Drilling Simulator 2”.

Other features also available:

A graphical very useful tool for training of roughnecks, derrickmen, drillers, toolpusher, drilling engineers and students in the well control procedures.

– Ability to drilling, kick detection, shut-in, stabilisation of pressures;
– Interactive System: no pre-set methods;
– Ability to apply control methods: Driller’s method, wait and weight, dynamic volumetric and static volumetric (lubricate and bleed);
– Hydraulics and Hydrostatics;
