    a brief intro about well testing

    Well testing is an important process and it is needed in order to evaluate the reservoir production potential. It consists of fluid production during a relatively short period and measuring the three main variables which are evaluation, time, flow rate and pressure. Well testing is usually done during exploration, development and production periods of an oil field, always in order to collect data that clarifies knowledge about the field and the economic viability of its production.

    Important quantitative parameters are estimated through well testing such as absolute permeability, skin factor, wellbore storage co-efficiency, reservoir volume, average pressure, etc. These parameters are estimated by comparing the measured field data against theoretical mathematical models based on the continuity equation and Darcy’s Law, that leads to the diffusivity equation, and a set of boundary conditions.

    PLEASE CORRECT MY LETTER!

    Dear Tom,
    Thanks for the letter. It was great to hear from you again. I should have written sooner but I have been busy with my exam.
    You asked me what sport there is in my school. Unfortunately, we only have football and basketball. In my opinion, people usually go to watch big sporting events in a sports bars or stay at home with friends. Personally, my favourite sport is dancing. I Fell relaxed, happy, and energised when I do it.
    Anyway, I am very happy that your dad’s bought a new car. What colour is it? How much was the car? Where did he buy it?
    Sorry, I have to go now. I need to prepare for my exam again. I look forward to your reply.
    Best wishes,
    Christina

    Football evening

    This is a football week. We have Champions League semi final matches. Spain has two teams in this phase: Atlético Madrid and Real Madrid. Two teams with two different styles. Atlético has stubborn and effective play thanks to its team play concept. On the other hand, Real Madrid has effective play thanks to its millionaire stars. I enjoy the Champions league but neither Atlético Madrid nor Real Madrid are my teams. I prefer to follow the Liga Adelante (The second spanish football league) because my team, Córdoba play there.

    Yes light clothes makes sense however as you are comparing the clothes to winter clothes it is better to say "lighter clothes"

    "Good" is used when describing something e.g. That film was good "Good at" is used when specifying what the person or thing is good at doing e.g. Tom is good at playing football. "Be good" is an order given to someone, for example a mother telling her children to behave well.

    The Rope

    Rope is a film by Alfred Hitchcock, starring among others James Stewart, which was released in 1948 and became a blockbuster. To make this movie Hitchcock got inspiration from a stage play entitled Rope's End, by Patrick Hamilton. The film is based on real facts, which happened in 1924: the abduction and murder of a teenager. On May 21, 1924 two young men, Loeb and Leopold aged 18 and 19 abducted and murdered a 14-year-old-boy. Both of them were very intelligent and came from rich families. They did it just to prove that they were able to, and because they were convinced that they could get away with it. They thought that they were smarter than everyone else and that they would not be caught because they had committed the perfect crime. Of course, they were not as intelligent as they believed and were caught and arrested. They were not sentenced to death thanks to a twelve-hour speech made by their lawyer, which persuaded the judge and they got a life sentence instead. Loeb was killed by another prisoner in 1936, while Leopold got out on parole in1958 and moved to Puerto Rico, where he lived the rest of his life.

    Could you correct my small post 15 sentences please mant thanks in advance

    Good day to you!
    How are you doing? I hope all is well with you and your family.
    What's the weather like near you? Over here, it has been raining since morning and it hailed heavily twice for five minutes.
    As for me I am doing ok. Although I must admit that sleepless and fretful nights because my baby is waking me up are making me a bit exhausted. I am trying to catch up on sleep during the daytime but my problem is that I can't fall asleep.
    My baby has got used to being in my hands all the time. I don't mind as my husband has ridded me of all household chores so my only duty now is to take care of our baby.
    Unfortunately, I have no time on my English now.
    But I am watching a documentary about Scotland by the BBC. It's quite interesting and I like the narrator's way of speaking and the background music.
    That's all my news for now.
    I will do my best to keep in touch with you.
