Allspeeds Limited has designed a new, smaller-bore, Millingford sucker rod pump to extend the life of marginal and starved oil fields. The 1.25-inch bore, pump can be used to reduce the pumped volume per stroke by almost half, thereby minimising the effect of pump-off.
In production since the 1950s, the Millingford range of subsurface pump bore sizes now range from 1” to 4 3⁄4” diameter with mechanical, cup type (chevrons) or friction type hold downs available in a variety of materials to suit specific well conditions.
As oil wells are gradually exhausted, there is not enough fluid to supply the rod pump, causing pump-off – where more gas than liquid is being pumped. In addition to the fall in the efficiency of oil extraction, the pump itself may be damaged. The 1.25” inch bore sucker rod pump will lead to a 45% reduction in pump volumes compared with standard 1.5” pumps. This reduces the quantity of liquid pumped from starved wells but allows the pump to run continuously without damaging surface equipment. Special adapters are used to allow the smaller pump to be fitted in place of the normal sized pump.
The new, smaller bore pump, is further evidence of the ability of Allspeeds Limited to adapt designs to specific customer needs and enhances their existing portfolio of sucker rod pumps and spares.
Allspeeds manufactures the complete Millingford sucker rod (insert) pump and tubing pump assemblies including plunger, barrels, valve cages, balls, seats and fittings within its ISO9001 QMS. Millingford plungers and barrels are engineered for optimum performance and longer life. Plungers can be supplied with electro less nickel-plated threads and/or bores to improve performance in extreme corrosive conditions. Barrels are made from a variety of materials, and precision honed and polished to a world class standard.
Millingford is just one of the brands manufactured by Allspeeds Limited, from their works in Clayton-le-Moors, Lancashire, with the others being Webtool (hydraulic cutters and grippers), Tangye (jacks and pumps) and Kopp (variable speed drives).
Allspeeds’ facility includes extensive development, manufacturing and test facilities. All work is performed in line with ISO 9001 quality standard with all products fully traceable from raw materials to the finished product. Testing facilities were designed to meet Allspeeds’ needs as well those of the customers wishing to witness factory acceptance testing.
With a suite of eight CNC machines, together with grinding, honing and other general purpose machinery and with dedicated fitting, assembly and spray paint areas, almost all aspects of our finished products are completed in-house, which reduces the dependency on third-party involvement, keeping control of lead-times within the company.
