Wellhead

1. Pressure Containment: The wellhead provides a pressure-tight seal to prevent the escape of reservoir fluids (oil, gas, or water) from the wellbore. It contains the high pressures found deep within the well.
2. Connection Point: The wellhead serves as a connection point for various surface equipment, including production tubing, casing, control valves, and flowlines.
3. Control Valves: Control valves, such as chokes and safety valves, are often integrated into the wellhead to manage and control the flow of fluids from the well. These valves regulate pressure and flow rates.
4. Monitoring Points: Pressure and temperature sensors are typically installed on the wellhead to continuously monitor downhole conditions. This data is crucial for well control and optimization.
5. Safety Measures: Wellheads may include safety features like blowout preventers (BOPs) to prevent uncontrolled releases of hydrocarbons, especially during drilling, completion, and well testing operations.
7. Tubing Hanger: In wells with tubing strings (common in production wells), a tubing hanger supports the tubing and provides a seal to prevent fluid escape.
8. Production Tree: In many cases, a production tree is installed on top of the wellhead. It's a set of valves and fittings used to control the flow of hydrocarbons from the well to the production facilities or pipelines.
6. Casing Hanger: The casing hanger is a component of the wellhead that supports the casing and provides a seal between the casing and the wellhead. It helps maintain well integrity.
6. Casing Hanger: The casing hanger is a component of the wellhead that supports the casing and provides a seal between the casing and the wellhead. It helps maintain well integrity.
9. Fluid Separation: In some wells, particularly those producing water along with oil and gas, a separation system may be integrated into the wellhead to separate and collect different phases (oil, gas, water) before they are transported.

Wellheads are designed to withstand high pressures, corrosive environments, and extreme temperatures. They are a crucial part of ensuring safe and efficient oil and gas production operations. The specific design and components of a wellhead can vary depending on the well's purpose, depth, and the characteristics of the reservoir.

What are the types of x-mas trees?

a production tree, also known as a Christmas tree, is an assembly of valves, spools, and fittings used for controlling the flow of oil or gas from a well. The type of production tree used depends on factors such as well conditions, production requirements, and safety considerations. Here are some common types of production trees:

Conventional Christmas Tree: This is a standard configuration used for most conventional wells. It includes valves for controlling the flow of oil or gas, as well as other components such as a choke, master valve, wing valve, and pressure gauges.
Dual Tubing Christmas Tree: In wells with dual tubing strings (two separate tubing strings for production), a dual tubing Christmas tree is used. It allows for independent control of each tubing string.
Through Tubing Christmas Tree: This type of tree is designed to accommodate through-tubing operations, where tools or instruments are run through the tubing string without the need to pull the tubing.
Horizontal Christmas Tree: For wells with horizontal completions, a horizontal Christmas tree is used. It is designed to handle the challenges posed by horizontal wells, such as controlling flow from multiple zones.
Dual Completion Christmas Tree: In wells with multiple reservoirs, a dual completion Christmas tree is employed. It allows for the independent control of each completion zone.
Vertical Subsea Christmas Tree: Subsea Christmas trees are installed on the seafloor for offshore wells. A vertical subsea tree is suitable for vertical well completions.
Horizontal Subsea Christmas Tree: This type is designed for subsea completions in horizontal wells. It provides the necessary control for horizontal well configurations.
ESP (Electric Submersible Pump) Christmas Tree: In wells that use electric submersible pumps for artificial lift, a specialized ESP Christmas tree is used to accommodate the pump and control its operation.
Slimhole Christmas Tree: Slimhole trees are designed for wells with smaller diameters. They are often used in slimhole drilling and completion operations.
Smart Christmas Tree: Some modern trees are equipped with smart technologies, such as sensors and communication systems, to enable real-time monitoring and control of well parameters.

The selection of the production tree depends on the well's characteristics, the type of reservoir, and the production strategy. Each type of tree is designed to meet specific operational requirements and ensure the safe and efficient production of hydrocarbons from the well.

The Sealer

First it is drilled for the sealer ( that big hole box) it also prevent or save the well from any eruption or rocks to fall down in the well production casing while coil tubing or slick line are working

The Conductor

Second we drill in the ground and we put the Conductor conductor by hammering it until refusal point ( when we hammer on the conductor 160 times and it moves only one feet). We pump cement to put it between the conductor and the mud to be fixed (not necessary)

Collar or coupling

That pipes in the conductor jointed together with a threatening pipe called collar or coupling

Surface casing

We put another pipe inside the conductor its name is surface casing We repeat the cement process against to fix the casing pipe too

Intermediate casing

Then we put the Intermediate casing and the cement also

The reservoir

That hole that contain the fluids

Production tubing

Then we put a tube inside the Intermediate casing going to the liner linear is the distance between the end of that tube going to the reservoir

Linear

The packer is put between the tube and the intermediate casing to fix the tube, to isolate between annulus and mud downside and to pump the brine to equal the pressure outside the tube and inside the tube with the oil

Brine/Erine liquid

we pump Brine to the water in the annulus to prevent the casing from corrosion and the pressure of the annulus should be 0 and 200 maximum.

Flabber or the dowmhole

Flabber is put in the tube near the surface for emergency shutdown and it works with the pressure we put from the downhole to open it and it shut with the pressure of the oil flow

Annulus

The annulus is the gap between the tube and the Intermediate casing and production tubing from it We pump the Brine and we can make bleed off from that annulus There are three annulus A 9 5/8, B 13 3/8, and C

Production casing

There is a production casing which I think it's same as tubing and the final pipe going down inside intermediate casing
A liner is a shortened string of casing used to case the small open hole section below an existing casing string in a hole it's just like casing except that a liner doesn't run all the way to the surface . Instead the casing crew hangs it from the bottom of a previously run casing or liner string using a special piece of equipment called liner Hanger it is used to save money

Clamp

It should be between annulus A valve and annulus B valve

Guide shoe

The guide shoe is a a heavy steel and concrete fitting but the crew makes up in the end of the first casing joint to go in the hole, it guides the casing rough spots and ledges in the wellbore. It also has an opening and the end. Drilling mud enters this opening when crew runs casing into that wellbore - later cement will come out from this opening on its way into the annulus

The Separator

The gas line :- To increase or decrease the orifice (run the orifice) you need to do the following
1/ open the equalizer and open the gate then adjust from the carrier to make it in the upper chamber or down chamber finally open the upper chamber valve then close all previous valves inverse gate valve and equalizer. Gas line can go to the production line and go for burner line by a diverter in the gas line in the Separator
The oil line:- I can adjust the level from the lcv box to make the level stable and control form the pcv only
The Separator can be three phases (water, oil and water) or two phases (liquid and gas)

Why do we have two different sizes of gas lines?

For low flow rate it is only suitable to use the smaller line because the bigger line of PCV will not be able to maintain a stable pressure inside separator.
For high flow rate it is only suitable to use the bigger line because if you flow through the smaller line would get turbulent flow which would give inaccurate flow measurement.

What type of valves do we use in lcvs and pcvs?

Throttling valves.

What is the pressure setting for the relief valve on separator and surge tank?

Explain separator inner parts.

Deflector plates (Inlet configuration): This plate is located in the front of the inlet it causes a rapid change in direction and velocity of the fluids, forcing the liquid to fall to bottom of the vessel. The deflector plate is responsible for the initial gross separation of liquid and gas.
Coalescing plates (Intermediate Configuration): These plates are arranged longitudinally in an invert V-shape in the upper part of the separator, the liquid droplet in the gas hit the plates and stick to them, as more gas through the plates, more droplets coalesce to form bigger drops that fall to bottom of the vessel.
Weir plate (Intermediate Configuration): This plate located at the bottom of the separator, divided the separator into two compartments (Oil and Water) provided that the water level is controlled, it only permits oil to overflow into the oil compartment.
Foam breaker (Intermediate Configuration): This piece of equipment is made of wire mesh, like the mist extractor. It prevents oil particles in the foam (comprised of oil and gas) from passing through the separator and being carried away with the gas.
Mist extractor (Outlet configuration): This piece of equipment is composed of a mass of wire netting. Before leaving the separator, the gas stream passes through the mist extractor, causing the tiny oil droplets remaining in the gas to fall down.
Vortex breaker (Outlet configuration): These breakers are located on the oil and water outlets. their function is to break the vortex effect that can occur when oil and water exit the separator from their respective outlets. the vortex breakers prevent any gas from being sucked away with the liquids.

What is the difference between junior and senior Daniel?

For Junior Daniel It has a single chamber which makes it impossible to change the orifice size when you are flowing through gas line without stopping the operation.

In the context of well testing, "ESD" commonly refers to "Emergency ShutDown" or "Emergency Shut-In." This term is related to safety measures and protocols in the oil and gas industry, particularly when conducting well testing operations.
An Emergency ShutDown (ESD) system is designed to rapidly and automatically shut down or isolate a well or a facility in the event of an emergency. The purpose of an ESD is to mitigate risks, protect personnel, and prevent or minimize damage to equipment and the environment.
During well testing, various factors such as high pressures, unexpected flow conditions, equipment malfunctions, or safety breaches could pose a risk. In such situations, the ESD system can be activated to quickly close valves, isolate the well, and bring the entire system to a safe and controlled state.

Key components of an ESD system in well testing may include:

Emergency Shutdown Valves (ESVs):
These are valves that can be automatically or manually closed to stop the flow of fluids in the event of an emergency.
Control Systems:
Automated control systems are used to monitor key parameters such as pressure, flow rates, and temperatures. If any parameter exceeds predefined safety limits, the control system triggers the ESD.
Safety Instrumented Systems (SIS):
These are systems designed to ensure the safe operation of a process or facility. They include sensors, logic solvers, and final elements (such as valves) that actuate in response to predetermined conditions.
Emergency Response Procedures:
Well testing operations have well-defined emergency response procedures that guide operators on how to handle emergency situations, including when and how to activate the ESD system.

Emergency Shutdown (ESD) valves

Emergency Shutdown (ESD) valves are critical components in safety systems, especially in the oil and gas industry. They are designed to quickly close and isolate a process or equipment in emergency situations to prevent accidents or protect personnel and assets. Various types of ESD valves exist, and the selection depends on factors such as the application, fluid type, and system requirements.

Ball Valves: have a rotating ball with a bore through it. In the closed position, the ball blocks the flow path, providing a quick shut-off. Ball valves are often used for ESD applications due to their fast-acting nature.
Gate Valves: use a gate (usually a flat or wedge-shaped disc) to block the flow. They are suitable for applications where a tight seal is required. Gate valves may have rising or non-rising stems.
Butterfly Valves: have a disc that pivots on a central shaft to control the flow. In an emergency, the disc can be quickly rotated to the closed position. Butterfly valves are known for their quick operation.
Piston Check Valves: Piston check valves use a piston-like disc to control the flow. In an emergency, the piston is forced into the closed position, preventing backflow.

Choke manifold compotents

It controls the flow rate and the pressure of the well head
It's located downstream of the flow head
The maximum size is 128 which it equals two inches
Adjustable choke and fixed choke

why the adjusable choke on the right side of the chokemanifold ?

The Adjustable choke is in the right side for emergency if something happen we can easily close it in the same direction of the flow to be easy to close.
To maintain the direction of flow to be the same of closing direction of adjustable choke.

chokemanifold features:-

chokemanifold is used to control the fluid from the well by reducing the flow pressure and by achieving a constant flow rate before the fluid enter the processing equipment on the surface.
Four gate valves
a posititve or fixed choke.
Tapping points for measurements of the upstream and downstream pressure
Thermometric well to monitor the temprature of the well
An adjustable choke

changing from the adjustable to fixed choke

preparation of fixed choke adjust the adjustable choke until the flow stabilizes, then prepare the equivalent fixed choke to be installed

pessurizing fixed choke box open the downstream valve of the fixed choke box to equalize the pressure (it is advisable to open the downstream rather than the upstream for safety measure)

Diverting the flow from adjustable to fixed choke open simultaneously upstream valve on the fixed side wile the upstream valve of the adjustable side is closed

flow through fixed choke the downstream of the adjustable side is closed in pressure bled off on the adjustable choke.

chokemanifold principle functions

safety function by controlling the well head pressure
it allows different choke sizes to control the flow rate
it prevents wate and gas coming by limiting the flowrate
it prevents formation sabd from entering the well by limiting the flow rate
it ensures critical flow where the pressure fluctuations downstream of the chokemanifold do not affect downhole pressure and flowrate of the well.

chokemanifold types according to:-

working pressure (5kpsi, 10kpsi, 15kpsi)
types of gate valves (McEvoy, Marbranque, Sereg, and WOM)

The procedures to change from adjustable choke to fixed choke :-

bleeding the fixed choke between upstream and downstream valves to the tank
prepare the choke bean size
open the fixed choke valve
get the choke bean out and put the new one
close the fixed choke cover
do a function test for the bleeder valve by opening the downstream fixed choke valve
open the upstream fixed choke and close the upstream fixed choke simultaneously
close the downstream adjustable choke

why the low pilot is upstream of the choke and high pilot is downstream of the choke :-

low pilot is upstream of the choke manifold

high pilot is downstream of the choke manifold
because if the downstream pressure doing up more than the pressure of the high pilot predefined on so the line will shutdown to protect our equipment as a safety meassures
