النايت بوشر في الصباح 😆

26/04/2025

I’ve dedicated many years of my life to the oilfield 🔥 - a life where every hitch begins with a silent prayer and no guarantee of making it back home.

We’ve faced long drives through thick fog, battled brutal weather, and flown across continents to do our jobs. We put in over 100 hours a week — sometimes grinding through 20 to 24-hour shifts in unforgiving heat or freezing cold. And we did it without hesitation… for the ones we love.

To all my brothers and sisters in the oilfield - God bless you. You are the toughest, most resilient people I’ve ever known.

Being an oilfield hand means sacrificing what matters most - missing birthdays, anniversaries, and holidays - to provide a better life for our families. We do the hard jobs, the long hitches, the night shifts. We power the world quietly - keeping homes warm, cars running, and lives moving. Even those who criticize what we do still enjoy the comfort our work brings.

We work hard, and we play hard. And through every day, every week, every month… we count down the moments until we’re finally back home with our loved ones. There’s no better feeling than that first hug after a long hitch.

And today, I ask you - please take a moment to remember the ones who never made it home. Their hitch never ended. They gave everything for this life, and we honor their sacrifice.

God bless all my oilfield brothers and sisters.

Liner Hanger Explanation:

A liner hanger is a mechanical device used in oil and gas wells to hang a liner (a shorter casing string) inside the previously run casing. This technique saves time and cost while maintaining well integrity.

There are two main types:

1. Conventional Liner Hanger

How it works:
It uses mechanical slip elements that grip the inside wall of the casing to hold the liner.

Setting method:
Set by applying weight or rotation to activate the slips.

Advantages:

Reliable in many well conditions.

Can handle high loads.

Disadvantages:

Requires precise setting tools.

May cause casing damage if not properly handled.

2. Expandable Liner Hanger

How it works:
It expands a metal section outward until it tightly presses against the casing wall.

Setting method:
Set by hydraulic expansion without mechanical slips.

Advantages:

Provides a larger internal diameter (ID) after setting.

Less risk of casing damage.

Good for high-pressure, high-temperature wells.

Disadvantages:

Requires special tools and careful pressure control.

Sometimes more expensive.

Oil Well Cement Additives

Additives play significant role in oil and gas well cementing operations. There are varieties of cement additives that have been developed to allow the use of Portland cement in many different oil and gas well operations.

In an attempt to formulate the appropriate cement slurry for any cementing job, the right additive must selected and the right quantity must be added. Additives have different functions and are broadly classified as:
▪️accelerator
▪️retarders
▪️extenders
▪️fluid loss agents
▪️dispersants and many more.
.
Each of the broad classification has different categories of additives that have been developed to perform almost the same function during cement slurry design.

1. Accelerators
Accelerators are added to shorten the time for cement to properly set and it will reduce rig time while waiting on the cement (WOC). Accelerators are crucial in shallow depths where bottom temperature is low. In the deeper section, it may not require an accelerator, because the well is hot enough and the thickening time will be normal. The WOC time is generally based on the time required to obtain 500 psi compressive strength of the cement.

2. Retarders
Retarders have the opposite function as accelerators because they are used to prolong thickening time of cement in order to prevent premature setting of cement. Retarders are used in the deeper hole section where bottom hole pressure is high.

3. Light Weight Additives (extenders)
Lightweight additives are used to reduce slurry density. Some sections in the well may require a reduced cement weight because a formation fracture gradient is quite low. With normal cement density, it can cause cement losses and it will result in a bad cement job. Reducing the cement density will cause decreasing in compressive strength and increasing in thickening time.

4. Heavy weight additives
Heavy weight additives are added in order to increase slurry density. Some overpressures zones must be cemented with a high density cement.

5. Fluid Loss Additives

6. Friction Reducing Additives

Types of Caprocks in Petroleum System

▪️Cap rock
Caprock is a rock that prevents the ﬂow of a given ﬂuid at a certain temperature and pressure and geochemical conditions. The caprocks can be categorized into three types:

1.🔽caprocks are typical for argillaceous sequences in a state of continuing compaction; they are developed in areas of young subsidence of Earth’s crust, with abnormally high pore water pressure. Sealing properties of these rocks are determined by the amount of capillary pressure at the contact of the reservoir and caprock, the pore pressure of water saturating the caprock, initial pressure gradient of water and the variation of hydraulic forces in the section. Oil and gas accumulations have higher potential energy than that of the formation water.

2.🔽caprocks are associated with rocks compacted beyond the plasticity limit and having lost ability to swell on contact with water. Such rocks do not contain swelling clay minerals, and interstitial water contains surfactants. Consequently, pore water in these rocks does not have initial pressure gradient. This type of caprocks is encountered mostly in the Paleozoic and Mesozoic sediments of young and old platforms. There are no clear-cut overpressure environments there, but there is a relatively clear hydrodynamic subdivision in the section. the hydrodynamic environment may improve or lower the sealing capability of caprocks. In an extreme case, the water potential in the reservoir may exceed the water potential of the bed overlying the caprock by the value of capillary pressure. In such a situation, the caprock will be open for the vertical ﬂow of hydrocarbons, and the trap will not exist even when potential distribution in the reservoir bed is favorable.

3.🔽caprocks are typical for rocks with a rigid matrix and intense fracturing. Such caprocks are mainly developed over the old platforms in regions of low tectonic mobility, with no detectable hydrodynamic breakdown of the section. Formation water potential in such regions is practically equal throughout the section and corresponds to the calculated hydrostatic potential.

Inside BOP valve (Gray Valve)
Insider Blowout Preventer (IBOP) valve has several industrial names as drill pipe float valves, Gray valves, Omsco valves and drop-in dart valves.

Figure1: Inside BOP (Dart Type)

This valve is a non-return valve (check valve) allowing pumping through the valve into the drillstring but it prevents upward flow and the more widely used type is “dart-type”. The dart is used to hold the tool open therefore it is possible to stab the valve while the fluid is flowing through the drillpipe. With the IBOP valve installed in the drill string, it allows you to strip in hole without mud flowing through the drillsting. The IBOP valve should not be used for shut the well in while tripping.

Understanding Gas Cap Drive Reservoirs

The illustration highlights the structure and production dynamics of an oil reservoir with a gas cap drive mechanism.

Cross-Section View (A):

Two oil-producing wells are completed in the oil zone beneath the surface.

The reservoir is divided into two main sections:

Gas Cap: The upper layer, consisting of natural gas.

Oil Zone: The lower layer, saturated with crude oil.

Gas from the gas cap expands and moves downward and outward, helping to push the oil toward the wells.

This natural gas expansion provides the energy needed to drive oil production, maintaining reservoir pressure in the early stages of production.

Map View (B):

From above, the gas cap occupies the central part of the reservoir, surrounded by the oil zone.

The producing wells are strategically located to efficiently drain oil without causing early gas breakthrough.

The gas expansion is radial, pushing oil toward the wells from all directions.

Key Insights:

Gas Cap Drive: A primary drive mechanism where the expansion of the gas cap maintains reservoir pressure and supports oil production.

Reservoir Management: Proper control of production rates is essential to prevent gas coning and to maximize oil recovery.

Well Placement: Strategic well positioning is crucial to optimize reservoir performance and delay gas production.

In gas cap drive reservoirs, understanding the interaction between the gas and oil phases is vital for designing effective production strategies and achieving maximum recovery.

The gas that accumulates in the upper portions of a reservoir where the pressure, temperature and fluid characteristics are conducive to free gas. The energy provided by the expansion of the gas cap provides the primary drive mechanism for oil recovery in such circumstances.
