## What is Mud fluid?

Mud fluid - an app for mud engineers that allows you to quickly calculate the time and volume of wellbore flushing. For convenience, well flushing is divided into drilling intervals: surface casing, production casing and liner. It is also possible to calculate the weight of the solution and the dilution.
At the moment only metric units are available, in the future there will be an update to the ability to select imperial units

## Key features

### 5/5 — Спасибо!

*2026-05-02, version 2.0.0*

Обновление отличное, удобнее чем ползунки. Но просьба добавить «техничку» и возможно «пилот»

### 3/5 — На тройку

*2025-07-11, version 1.4*

Нельзя выбрать плотность добавляемого раствора меньше 1
Неудобные ползунки

### 3/5 — Баг

*2023-06-08, version 1.4*

Не стало считать «Промывку скважины», Кондуктор, остальное считает правильно

### 5/5 — Baroid

*2023-01-11, version 1.3*

Приложение работает без нареканий!!!👍🏻

### 5/5 — Приложение топ

*2022-06-28, version 1.3*

Быстро помогает рассчитать утяжеление бурового раствора

### 3/5 — mud fluid

*2022-05-08, version 1.3*

Не корректно работает в iOS 13.3, «обложка» приложения увеличена (как под лупой), надписи «Настройки» не видно, данные начальный плотность и начальный объём не даёт корректировать («ползунок» не передвигается).

### 5/5 — Полезное приложение

*2021-10-19, version 1.2*

Удобно, можно оперативно посчитать утяжеление БР непосредственно на буровой. Хотелось бы ещё чтобы добавили расчёт рассолов солей по плотности калий хлористого и галита.

### 5/5 — Отлично!)

*2021-09-23, version 1.2*

Приложение отличное,большое спасибо автор) Очень удобно теперь иметь всегда при себе в помощь,хоть на буровой,хоть на планерке)) Есть небольшая просьба,не могли бы добавить возможность в разделе утяжеления и смешивания выбрать плотность,меньшую чем 1.00 г/см3? При работе с РУО необходимо) В остальном все отлично!

### 5/5 — Отлично!

*2021-09-17, version 1.2*

Отличная приложуха! Респект автору!

### 5/5 — Мобильно и удобно

*2021-08-28, version 1.1*

Спасибо за работу, очень удобно когда находишься на буровой на промывке. Сделай пожалуйста ещё приложение на утяжеление , смешивании разных плотностей и тд бурового раствора. А так же содержания твёрдой фазы при использовании барита, мела, галита.
