For some of you, I’d like to share a little bit of my background.
My background stretches back roughly 26 years in the oil and gas industry. I’ve done my time on the completion side. I’ve done work on the drilling side for number of years. The completions or production side for a number of years. That’s where my passion in the industry really lies, is in production.
For the past probably 15 years before getting into the sales side of the oil and gas industry, I spent those years pumping for a couple of different companies in the Permian Basin. And really getting to know the ins and outs of pumping units. And that’s what I like to talk to you a little bit about today.
I know most of you already know the basic components of a pumping unit. You’re walking beams, your horse’s head, saddle bearings, tail bearings, wrist pin patterns, Samson posts, gear reducers, things of that nature and the benefit of SPOC and SPOC providing our variable frequency drive, can really help your unit survive. And when I say survive, I mean hard starts. If you’re just running a typical pumping unit with a control panel, when that pumping unit is kicking on and kicking off, as you very well know, it’s a hard start. It’s a hard start that’s bad for your motors, bad for your gear reducers, your saddle bearings, your tail bearings and even works its way down to the actual nuts and bolts of the pumping unit itself. With the hard starts, of course, over and over, hundreds and possibly thousands of starts and stops throughout the lifetime of that well, and the lifetime of that pumping unit sitting on that well. You get bolt back off. A lot of your bolts start loosening up. Of course, that’s going to make problems for that area. If it’s your Samson posts that’s loosening up or whatever that may be. And one-way SPOC Automation is able to help you and help your pumping unit survive those hard starts is with the soft start of a variable frequency drive.
And I don’t know about you, but I don’t think I’ve ever heard of any motors actually burning up out in the field that actually has a variable frequency drive attached to it. You’re going to get, like I said, a lot softer start. It’s not going to get that massive jolt. So, as soon as that unit is energized, you’re getting 480 volts hitting right to that panel then goes straight to that motor, kicking it on violently.
The other benefit, of course, is your pumpers out in the field. Your pumpers are able to lower or increase your strokes per minute just by using a dial, or using the touchscreen provided with the SPOC variable frequency drops. And with that being said as well, you’ve got a declining well, you’ve put that well online. It’s running eight, 8.5 strokes, minute production starts falling down, the pumper or foreman suggests let’s slow that thing down to six strokes a minute. What do you do? You call out of crew. They’re going to come out. They’re going to do a shift change for you, depending on where your location is for driving time, things of that nature. A basic cost of changing your unit down to get that thing running at six and six strokes a minute, you’re looking at between $500 -$1,000 for that crew to come out and do that when with a variable frequency drive installed on your unit it just takes a hand dial. Let’s just turn it down or let’s get on the keypad and let’s drop those strokes per minute down. Keep that unit running 24 hours a day. And that’s also going to help — just like I said in the beginning of your hard starts with that unit running on a pin timer or if it’s running on a time clock, whatever is going to start and stop, start and stop, start and stop. That’s wear and tear on any item. Especially with a pumping unit, with the number of moving parts of that unit has.
I’ll just go back a little bit to talking about the different parts of the pumping unit that it’s going to affect. That’s going to affect your walking beam. That’s going to affect your horsehead. That’s going to affect your tails, your saddles, your wrist pins. Everything on that unit is going to take its toll.
And with that being said, if any of you have any questions regarding SPOC’s variable frequency drive or if you just have any questions. Please feel free to pick up the phone and give me a call any time or shoot me an email. That’ll do it for this this episode. I wish all of you like a very blessed day and thank you very much for your time.
