## What is Pipes (Oilfield)?

Pipes (Oilfield) App computes the volumes and weights of various oilfield pipes. This includes the calculation of:
	- The metal displacement volume for an open-ended or closed-ended pipe string.
	- Primary cementing volumes
        - Liner cementing volumes
        - Cement plug volumes
        - Cement thru Coiled Tubing volumes
        - Bottom-Up and rat-hole volumes
        - Hole volumes without pipe in the well
        - Pipe volumes and partial displacement down a specific restriction in the drill pipes or Tubings.
        - Annular volume between Pipe/Hole and a CT string as well as CT capacity taking in consideration a CT reel volume at surface. 
        - The internal volume of a pipe string (pipe string capacity)
	- The annular volume between two pipe strings.
	- The annular volume between a pipe string and the open hole.
	- The annular volume between a pipe string and a combination of pipe string and open hole.

For annular volume calculations, the app allows the addition of an excess percent . This can be applied to either the open hole sections only or to open hole and outer pipe sections.

	- The weight of a pipe string in air or in a fluid (the calculator allows to define a different fluid density inside and outside the pipe string).
        - The friction and hydrostatic pressures in a pipe
        - The formation injection pressure 
        - The pressure drop across a bit or a nozzle
        - The circulating pressure in a drill or casing string or in a coiled tubing pipe..

Also, the Pipes (Oilfield) App allows each of the strings to be composed of three different pipe sections and the same applies to open hole. 

The app includes a complete database of all API casing, drill pipe and tubing pipes as well as the list of the most common coiled tubing and open hole sizes.

A provision of adding and deleting user's defined pipe details is available through the "User's Data" module. Moreover, the app allows saving the calculation details and sharing them through emails, messaging apps, and through iCloud account to different user's devices.

## Key features

- Metal displacement volume calculation
- Cementing volume calculations
- Annular volume calculations

## Frequently asked questions about Pipes (Oilfield)

### What types of volumes can Pipes (Oilfield) calculate?

Pipes (Oilfield) can calculate metal displacement volume, primary and liner cementing volumes, cement plug volumes, coiled tubing volumes, rat-hole volumes, hole volumes without pipe, pipe volumes with restrictions, annular volumes between pipes and open hole, and internal pipe string capacity.

### Does Pipes (Oilfield) support custom pipe data?

Yes, Pipes (Oilfield) includes a "User's Data" module that allows users to add and delete their own defined pipe details, providing flexibility for specific project needs.

### Can Pipes (Oilfield) calculate pipe weight in different fluids?

Yes, the app can calculate the weight of a pipe string in air or in a fluid. It allows for defining different fluid densities inside and outside the pipe string for accurate calculations.

### What pressure-related calculations does Pipes (Oilfield) offer?

Pipes (Oilfield) calculates friction and hydrostatic pressures within a pipe, formation injection pressure, pressure drop across a bit or nozzle, and circulating pressure in drill, casing, or coiled tubing pipes.

### How does Pipes (Oilfield) handle annular volume calculations with excess percentages?

For annular volume calculations, Pipes (Oilfield) allows the addition of an excess percentage. This excess can be applied exclusively to open hole sections or to both open hole and outer pipe sections.

### What is the pricing for Pipes (Oilfield)?

Pipes (Oilfield) is a paid application priced at $14.99. This one-time purchase grants access to all its features and calculations.

### What devices is Pipes (Oilfield) compatible with?

Pipes (Oilfield) is designed for iOS devices, including iPhone, iPad, and iPod. It requires iOS 11.0 or later.

### How often is Pipes (Oilfield) updated?

The application was last updated on January 20, 2023, indicating ongoing support and potential for future enhancements. The latest version is 5.8.

## Version history (last 5 releases)

### 5.8 — 2023-01-20

- The interface have been improved for iPhone 14 and 13 devises
- The naming algorithm for a calculation has been updated

### 5.7 — 2020-11-28

Several improvements are added to the "Pipes (Oilfield)" App, this includes:
- The "Rheology" module is added to calculate fluids parameters for various rheology models
- Improvement to the Dark and Light modes
- Interface improvement for new iPhones
- Several Bug fixes

### 5.5 — 2020-03-31

Several improvements and bug fixes are included in this version:
- The NEW "Pressure"module  is added to calculate circulating pressure, formation injection pressure and pressure drop across a nozzle.
- The casing, drill pipe, tubing, coiled tubing and open hole selection screen has been improved to allow quickly finding the desired pipe.
- When a fluid in skipped in the  cement plugs and thru CT cement plugs calculation, the calculated displacement volume was not correct. Now, you can use a wash and a cement slurry in the plug calculation and skip the spacer and the displacement volume will display the correct figure.
- The "Volume" module layout has been improved.
- Now if the name of the case is not filled, the module will auto generate a labeling (naming) which can be used to save the calculation.
- The User defined pipes labeling has been improved
- New casing and drill pipe sizes have been added to the app's database.

### 5.4 — 2019-12-08

Pipes (Oilfield) ver. 5.4 comes with many improvement.

The "Annular Volume" module allows the quick computation of :
- Primary cementing volumes
- Liner cementing volumes
- Cement plug volumes
- Cement thru Coiled Tubing volumes
- Bottom-Up and rat-hole volumes
- Hole volumes without pipe in the well
- Pipe volumes and partial displacement down a specific restriction in the drill pipes or Tubings.
- Annular volume between Pipe/Hole and a CT string as well as CT capacity taking in consideration a CT reel volume at surface. 

The UI has been simplified and data entry is made much easier to follow and quick to fill.

Many bugs leading to crashes when switching from a pipe database to another have been rectified. Also, depth entries input have been improved.

### 5.3 — 2019-01-05

No release notes.
