Keeping your air conditioning running efficiently isn’t just a matter of comfort. It can prove to be a matter of health and safety.

Air conditioning also helps control humidity. Humidity control helps prevent mold and mildew growth. Limiting mold and mildew growth protects your respiratory health.

So, here are five AC maintenance tips that will help keep your unit running smoothly.

1. Change Your Air Filters
Your HVAC system comes equipped with air filters to capture dust, pet hair, and other contaminants. These filters prevent those contaminants from interfering with your system’s operation.

Over time, those filters get dirty or clog up. A dirty air filter can often cause icing on your air conditioning unit, which pushes the unit harder than necessary. Changing out your filters once a month can help prevent this problem.

2. Clear Away Plants and Bushes
Your air conditioning unit needs freely flowing air to function correctly. As bushes, flower beds, grass, or weeds grow around the unit, they obstruct the airflow. Again, this pushes the unit harder than necessary.

Clear away any plant life you find growing near the unit. It ensures the unit gets enough air. That ensures a more efficient unit for your home.

3. Check the Drain Line
Your air conditioning unit needs to drain excess moisture from the condenser. This drain line can clog from algae growth.

You do some preventative maintenance by flushing the line from time to time with a small amount of bleach. One cup will usually do the trick.

If algae or mold has mostly plugged the line, a basic wet/dry vacuum cleaner can typically suck away the obstruction.

4. Get a Programmable Thermostat
Many people leave their air conditioning turned on all day, cooling an empty house or apartment. Others simply forget about adjusting the thermostat on their way out the door. This shortens the working life of the air conditioning unit and costs you money.

A programmable thermostat removes the human element. You simply program the thermostat for the temperatures you want at different times of the day. You save money and extend the efficient working life of the unit.

5. Schedule Professional Maintenance
A lot of things you can’t necessarily see may go wrong with an air conditioning unit. A professional technician can check these things, including:

Electrical components
Mechanical components
Coolant levels
Duct integrity
Calling a pro in once or twice a year ensures that your air conditioner stays efficient for as long as possible.

Parting Thoughts on AC Maintenance Tips
AC maintenance plays a crucial role in improving your air conditioning unit’s performance. Good DIY maintenance helps ensure proper airflow and drainage. A programmable thermostat makes sure you don’t run the unit more than necessary.

Professional maintenance lets you know that the electrical and mechanical components still work correctly.

BASIC CONCEPTS IN RESERVOIR ENGINEERING

In the process of illustrating the primary functions of a reservoir engineer, namely, the estimation of hydrocarbons in place, the calculation of a recovery factor and the attachment of a time scale to the recovery; this chapter introduces many of the fundamental concepts in reservoir engineering. The description of the calculation of oil in place concentrates largely on the determination of fluid pressure regimes and the problem of locating fluid contacts in the reservoir. Primary recovery is described in general terms by considering the significance of the isothermal compressibilities of the reservoir fluids; while the determination of the recovery factor and attachment of a time scale are illustrated by describing volumetric gas reservoir engineering. The chapter finishes with a brief quantitative account of the phase behaviour of multi-component hydrocarbon systems.
CALCULATION OF HYDROCARBON VOLUMES
Consider a reservoir which is initially filled with liquid oil. The oil volume in the reservoir (oil in place) is

The product Vφ is called the pore volume (PV) and is the total volume in the reservoir which can be occupied by fluids. Similarly, the product Vφ (1−Swc) is called the hydrocarbon pore volume (HCPV) and is the total reservoir volume which can be filled with hydrocarbons either oil, gas or both. The existence of the connate water saturation, which is normally 10−25% (PV), is an example of a natural phenomenon which is fundamental to the flow of fluids in porous media. That is, that when one fluid displaces another in a porous medium, the displaced fluid saturation can never be reduced to zero.
This applies provided that the fluids are immiscible (do not mix) which implies that there is a finite surface tension at the interface between them. Thus oil, which is generated in deep source rock, on migrating into a water filled reservoir trap displaces some, but not all, of the water, resulting in the presence of a connate water saturation. Since the water is immobile its only influence in reservoir engineering calculations is to reduce the reservoir volume which can be occupied by hydrocarbons.
The oil volume calculated using equ. (1.1) is expressed as a reservoir volume. Since all oils, at the high prevailing pressures and temperatures in reservoirs, contain different amounts of dissolved gas per unit volume, it is more meaningful to express oil volumes at stock tank (surface) conditions, at which the oil and gas will have separated. Thus the stock tank oil initially in place is


and the problem is to determine the level at which the oil water contact (OWC) is to be located. Measurement of the enclosed reservoir rock volume above this level will then give the net bulk volume V. For the situation depicted in fig. 1.1 (b) it would not be possible to determine this contact by inspection of logs run in the well since only the oil zone has been penetrated. Such a technique could be applied, however, if the OWC were somewhat higher in the reservoir.
The manner in which the oil water contact, or fluid contacts in general, can be located requires a knowledge of fluid pressure regimes in the reservoir which will be described in the following section.

"Limitation is a mentality that most people practice daily until it becomes their reality".

We see life through a lens. Through a pair of goggles. Via a filter. Made up of our closely cherished beliefs—and regularly run emotional patterns.
And we rehearse these constantly until they submerge into our subconscious.....if we’re not aware, we’ll believe what we see is true. Instead of recognizing that what we’re witnessing is simply our perception of what’s true.Instead of recognizing that what we’re witnessing is simply our perception of what’s true.

|Subsea & |Injection Wells|

Subsea wells
Subsea Wells are essentially the same as dry completion wells. Mechanically, however, they are placed in a subsea structure (template) that allows the wells to be drilled and serviced remotely from the surface, and protected from damage, e.g., from trawlers. The wellhead is placed in a slot in the template where it mates to the outgoing pipeline as well as hydraulic and electric control signals

Control is from the surface, where a hydraulic power unit (HPU) provides power to the subsea installation via an umbilical. The umbilical is a composite cable containing tension wires, hydraulic pipes, electrical power, control and communication signals. A control pod with inert gas and/or oil protection contains control electronics, and operates most equipment via hydraulic switches. More complex subsea solutions may contain subsea separation/stabilization and electrical multiphase pumping. This may be necessary if reservoir pressure is low, offset (distance to main facility) is long or there are flow assurance problems so that the gas and liquids will not stably flow to the surface. The product is piped back through pipelines and risers to the surface. The main choke may be located topside.



Injection Wells
Wells are also divided into production and injection wells. The former are for production of oil and gas. Injection wells are drilled to inject gas or water into the reservoir. The purpose of injection is to maintain overall and hydrostatic reservoir pressure and force the oil toward the production wells. When injected water reaches the production well, it is called “injected water breakthrough.” Special logging instruments, often based on radioactive isotopes added to injection water, are used to detect breakthrough. Injection wells are fundamentally the same as production wellheads. The difference is their direction of flow and, therefore, mounting of some directional components, such as the choke.

Permian Water Creates as Many Problems as It Solves
Water is precious, and it is a factor in every aspect of oil production in the Permian Basin. It is used to produce the hydrocarbons, and it is produced with them. In the often-arid region of the Permian, finding a balance between water production and use can be a challenge.
