Hello Alex, Thanks to your time immediately!
1-Can you inform our readers about your organization and background? 2-With respect to SWD wells what ought to operators keep in thoughts?
M and M Pump and Supply consists of three companies: 1. M and M Pump and Supply Inc., Clay Metropolis and Mattoon, Illinois selling Oilfield Tubulars and Sucker Rods, Tanks both steel and fiberglass, downhole oilfield pumps, optimistic displacement and centrifugal pumps, pipe, valves and fittings and absolutely anything that’s used to drill, full, or equip an oil or gas properly. We additionally service and restore natural gas engines, salt water pumps and have a whole stock of fibergass pipe and fittings for salt water injection strains. 2. PD Service Co., Clay City, Illinois furnishing oilfield trucking, oilfield development crews, tank trucks, tubing and casing testing and inspection crews, frac and swab tank rentals, steamers and oilfield threading providers. Three. McCoy Machine and Gear Co., Flora, Illinois furnishing full oilfield machine shop, new and rebuilt pumping units and cellular service trucks for area repair of pumping models and salt water pumps and manufacturing Miller Sand Pumps.
On the subject of salt water disposal and injection wells I might advocate working a good string of Sealtite Plastic or CPVC lined tubing to protect in opposition to inside corrosion and being sure to protect the anular space between the casing and the skin of the tubing with a very good corrosion inhibitor, oxygen scavenger and biocide in both liquid or pellet form. If you’re water flooding make sure to decide on a great producer on your injection nicely as these seem to make the perfect injection wells with the very best waterflood outcomes. Evidently have a petroleum engineer analyze your field for recoverable barrels of oil and desired injection rates per injection nicely to improve you odds of the best outcomes out of your waterflood. Establish an excellent chemical program for your injected water for management of corrosion and scaling tendencies. Beginning this program instantly is significant to minimizing problems down the street that would result in excessive pulling of each producing and injection wells in a waterflood. Make sure to have a chemical firm analyze injected and produced water for compatibility to stop potential extreme scaling and corrosion down the highway.
3-What type of pumps work finest for SWD wells? How do they work?
Every little thing with regards to pump choice for a salt water disposal or injection effectively is outlined by barrels per day of water to be injected and most stress required to inject the water at that price. As a result of most injection wells require anywhere from reasonable(300 to 700PSI) injection pressures to very high pressures(over 2000PSI) a constructive displacement pump reminiscent of a plunger or piston pump or a diaphragm type pump is often required. All positive displacement pumps require good water supply at the pump intake and it is essential to be sure this is achieved both by oversizing and flooding the pump suction or charging the pump suction with a correctly sized centrifugal pump. Pumps of this kind are usually powered by both an electric motor or gas engine with satisfactory horsepower to handle the utmost flow rate and pressures that the pump will be subject to. Brake Horsepower requirement is calculated by the next components: Gallons per minute instances Maximum Pressure occasions a constant of .000648 equals Most Brake Horsepower Required.
Four-I’ve heard much about Hydra-Cell and Cat pumps, are there another manufacturers to think about?
Among the more frequent brands of Constructive Displacement Pumps are Gaso, Wheatley, Oilwell, Gardner Denver, Bethlehem(B-Grasp), Kerr, Myers, Union, Ingersoll Rand, Cat, Hydracell among others. The key to selecting which pump works finest to your software as soon as again will depend on barrels per day to be injected and the stress wanted to perform this. One other key consideration can be having a distributor that stocks parts for and providers the model of pump you are going to purchase in order that downtime for pump servicing and repairs might be kept to a minimum. Hydracell Pumps are usually less expensive than plunger pumps if yow will discover one which meets your quantity and stress necessities. These pumps may even in all probability require completea substitute after 5 to 10 years in service. Huge plunger pumps such because the Gaso, Wheatley, Oilwell, Gardner Denver, Kerr, B-Grasp can run for forty to 50 years if properly mainained and rebuilt each 3 to 10 years depending on service situations.
Cat pumps fill the area of interest for low volume, very high strain applications notably properly at an affordable price, but substitute part prices are typically fairly expensive when the pump needs serviced. Probably a very powerful thing you are able to do for any of the above pumps is to develop a very good preventative upkeep program with explicit attention being paid to the situation of the oil in the power finish of the pump. Pumps on this service often run 20 hours a day or more so it is imperative that a every day preventative maintenance inspection is made and that fluid change intervals are followed religiously.
5-Do certain manufacturers have execs and cons?
6-Any maintenance or ongoing utilization precautions to take with these kind of pumps?
#5 and #6- I partially answered these questions when responding to query #4. Different maintenance concerns. Be sure you purchase a packing gland wrench for tightening plunger packing on plunger pumps in addition to a hammer style valve cover wrench for pumps with threaded valve covers. Some pumps use a deep socket packing gland wrench and a few require a spanner wrench. Along with daily energy end gear oil inspection, plunger packing must be tightened if plungers are leaking more than 3 to 5 drips per plunger per minute, nevertheless it’s imperative not to overtighten plunger packing as ceramic plungers which are usually used in salt water service will break if subject to heat over 150F and this can occur if packing is overtightened. It is normally greatest to let plungers run for a number of minutes after tightening packing, turn the pump off and then really feel the ceramic part of the plunger and ensure it is not hot to the contact, if it is your packing is probably too tight.
You probably have an injection properly that goes on vacuum and need to suck your tanks dry, install a verify valve with a heavy spring which won’t allow the well to suck your tanks down. This can stop plunger breakage due to the pump happening air and sucking any BS on high of your water into the pumps valves. I would also advocate installing a Y-strainer on the intake line to the pump to prevent debris from plugging the pumps valves. Make sure you inspect this strainer regularly and after the preliminary hour of pump operation and after 24 hours of preliminary operation, as there may be likely to be debris in newly assembled traces that would plug the strainer. When running Hydracell Pumps examine the gear oil each day as if you poke a hole in one of many diaphragms salt water could have direct access to the pumps powerend. Lastly you should definitely oversize the pumps intake(suction) line and use as few 90 diploma els as potential to insure satisfactory fluid supply to the pump. Remember the old adage that 6-90degree els almost equals a bull plug!!
7-Should an operator over compensate and buy a pump that is much larger Horse Power than is indicated?
A specific amount of security factor needs to be built into all pump and motor design within the event injection volumes exceed authentic estimates or more pressure is required to dispose of injected water than was originally estimated. Petroleum Refinery manufacture It’s also wise to not run any pump at its most recommended RPM as this will result in larger maintenance and rebuild costs than a pump being run at 80 to eighty five% of its most capabilities. I’d recommend designing your pump system at seventy five to 80% of a pumps quantity and stress capabilities. This will permit for some additional quantity and strain if needed without causing maintenance complications down the highway.
8-What’s a common downside you see in the sector?
Frequent issues which I see in the field are: A. Failure to correctly maintain powerend oil high quality leading to costly powerend overhauls. B. Failure to oversize pump suction lines and allow for sufficient water provide to the pumps intake valves resulting in premature valve failure. C.Failure to install a bypass valve on pump discharge strains resulting in catastrophic falure such as a damaged pump crankshaft is someone forgets and turns the pump on in opposition to a closed valve. D. Failure to display screen incoming water to pump and failure to often examine display in suction Y-Strainers, particularly when water is being hauled into the lease by tank trucks(Word; A settling tank is best used when water is being hauled into the lease by tank trucks.) E. Failure to put in a bleeder valve on pump discharge line to allow for bleeding any trapped air out of the pump. Failure to religiously observe a every day and weekly pump inspection and maintenance schedule.
9-Please Inform our readers about how to handle corrosive fluids within the pump?
With a view to properly prevent corrosion in a salt water pump, the fluid end of the pump should usually be cast from both aluminum bronze or 316 Stainless Steel that are extremely corrosion resistant. In some brines which are not too corrosive and where pressures are to not high a bronze fluid finish will present passable service at a price which is significantly cheaper than aluminum bronze or stainless steel. Nonetheless, commonplace brass has limited resistance to hydrogen sulfide and can often wash out quickly when handling brines that carry H2S. Additionally it is a good idea to chemically treat injected water for each corrosion and scaling tendencies as this will forestall your injection well from plugging off and protect your downhole tubulars.
