Decline initials proof

hi this video is going to be a brief introduction to decline curve analysis and this is where in an empirical almost are sort of extending the curve type of fashion we make predictions of future production and really what we're doing is we're making a base case prediction against which we can look at different things that we might be doing like drilling more wells or injecting other fluids so it's relatively brief presentation I'm going to spend too much time on it but at least I'm going to introduce the idea and I'm going to introduce the idea of decline and plateaus so by bringing up the whiteboard I'm going okay so let me let me explain what we're gonna do so let's have a plot here on this axis is time and on this axis is production right I'm going to call this production rate Q it's normally measured in say stop ten barrels a day and 0q is technically ok it's d MP MP is the cumulative production that's the total amount of all we've ever produced okay so who is the is the production rate I came by was per day tears time now finally enough time is measured here in years okay so as I said time zero may be the day at the time that you first discovered or imagined and we're typically just so that we get some sort of scale you know this may be ten years this may be twenty years normally if you're an independent oil company you want to reduce most of the field within twenty twenty-five minutes okay so that's your your typical timescale okay so what happens when you discovered oil but then you need to obviously plan what to do you need to do some of the analyses and described it already in this series of videos so nothing happens then you start drilling a well okay you may have problems and then your world comes on stream so your your flow rate goes goes up then it sort of plateaus then you drill a few more wells and so what you're hoping to is to get to a stage and the Tiffany rapidly which is this so this and maybe there's not a terribly good scale this may be of order one year so within a year or so depending on obviously the size and complexity of the field you hope to drill sufficient wells that you're producing at what's called a plateau rate this this is your platter now why do you platter right you have a plateau right a plateau rate is where you're producing at a fixed flow rate you might say well surely if the reservoir pressure state starts high and goes lower than maybe the rate declines over time which is where we're getting and but often what you do is you design your surface facilities so that they will handle a maximum amount of oil and so you're...
