This application uses the basic calculations of the Volumetric Method to control oil wells after the occurrence of kick during drilling operations on landing rigs (Onshore).
It is can be applied on the oilfield and also can help in the understanding of the Volumetric Method of well control.
This is a basic well control simulator for training in Oil & Gas that simulates the control applying the Volumetric Method (and Lubricate and Bleed Method) after the kick detection during stripping out the drillstring on the drilling operations in the oil well.
This is a project also based on app “Kick Game 2” available in our portfolio like the Driller’s Method Simulator and Wait and Weight Method Simulator. Like these apps, just surface parameters are displayed.
Features:
1. Interface based on Hydraulic Choke Panel. 2. Graph in full screen (with background color in black or white) for analysis. 3. Pre-recorded data sheet 4. Well Design with Casing + Open Hole without the Drillstring in the Wellbore. 6. Full features version with pause and digital gauges. 7. Method with Step by Step procedure to turn the exercise easy to practice.

There are several concepts about kick tolerance, but this article only deals with the concept of kick tolerance as the maximum kick volume.
Kick Tolerance is the maximum kick volume that can be taken into the wellbore and circulated out without fracturing the formation at weak point (normally at shoe depth), given a diference between pore density (equivalent) and the mud weight in use.
The maximum gas bubble height in the open hole can occur either at the bottom around the BHA (Bottom Hole Assembly) or when the volume is at its maximum when the gas reaches the the casing shoe.
Calculating the Gas Volume at shoe depth based on the Maximum Influx Height
Maximum Gas Volume at shoe = Hk,max x Annular Capacity DP and ID Hole)
1. Calculate V1 at bottom applying the Boyle’s Law: P1 x V1 = P2 x V2 (isothermal)
V1 = Vshoe x P,fracture / P,pore
2. Calculate V2 at bottom around the BHA with height equal to Hk,max,
V2 = Hk,max x Cap,ann,bha
Calculating volumes for Hk,max in the Directional Wells
Boyle’s Law
Normally, the formula used only considers Boyle’s Law, without considering that there is a temperature variation from the bottom of the well to the depth of the casing shoe.
Gas Law and Gas Compressibility Factor
For natural gas, the gas law is best applied because there is temperature variation in the well and the gas has a compressibility factor different from 1.
P x V = n x R x T x Z
P, Pressure V, Volume n, Number of moles R, Constant T, Temperature Z, Compressibility Factor of the gas
In this case, the calculations considering the Gas Law:
V1 = (Vshoe x P,shoe) / (Tshoe x Z,shoe) x (Tpore x Z,pore / P,pore)
Kick Tolerance (Max Vol) application
We develop an application with options to select temperature and/or the Z-Factor of the gas. It works with vertical wells and 3D directional wells.
Comparing Boyle’s Law versus Gas Law
On vertical well, the result is not affected when the volume calculated at the bottom of the hole is smaller.
Using the Boyle’s Law:
Using the Gas Law:
On directional well, the kick volume at the shoe depth converted to bottom of the hole is normally smaller and the result is affected when applying the Boyle’s Law or the Gas Law.
Note: In this directional well, the shoe depth is in a vertical section. So, height and length of gas bubble can be equal in a directional well.

BPP is a auxiliary component of the MPD System to provide flow to maintainBack Pressure during low-flow events or pumps-off events, such as in drill pipe connections.
When the rig mud pump is being ramped down slowly for connection purposes, the back pressure pump is turned on and ramped up when the rig mud pump drops below a set point. Flow by choke varies causing greater pressure variations, requiring more attention from the operators.
RPD is a necessary component of the MPD System to maintainBack Pressure during drill pipe connections using the flow provided by the mud pumps of the rig. The flow by choke does not vary. Pressure variations are smaller.
