Rod Pumps
Introducing the Rod Sentinel. Sivam has designed and patented the first fail safe, surface controlled subsurface safety valve for sucker rod application called rod sentinel - an innovative technology that changes the game in dual barrier policy of the oil and gas market. This Sivam safety valve can be applied in all sucker rod completed wells where it is necessary to comply with the dual barrier policy. The Rod Sentinel SCSSSV can be installed in landing nipple for 2.81 inches surface controlled wireline retrievable insert valves with standard profiles. The Rod Sentinel SCSSSV lock mandrel has been designed to be installed and retrieved by the sucker rod string in combination with the pump plunger so it completely avoids the cost and risk of a workover. The beam pump safety valve was designed in compliance with the fail-safe concept. Control line pressure keeps the valve open and when the pressure fails the preloaded power spring in the valve pushes the sealing pads within the cone housing and the valve closes using the same hydraulic control line technology as a conventional SCSSSV.

The Sivam Hybrid Downhole Pump is a rod pump that utilises the existing tubing as the pump barrel. The standing valve is installed first in a tubing profile, and the travelling assembly is then installed. Dual barrier options such as the Rod Sentinel can also be installed and recovered using the Hybrid Downhole pump. The Hybrid Downhole Pump increases fluid production by maximizing rod pump barrel size, and installation costs are minimised by being through-tubing installable. An excellent choice for well testing existing completions that do not have artificial lift installed. When used in conjunction with the Rod Sentinel SCSSV the Hybrid Downhole Pump is capable of dewatering gas wells, rod pumping critical sour wells, or for installation on lower rate offshore wells.

Sucker rod pumping systems are the oldest and most widely used type of artificial lifting system for oil wells. Sucker-rod pumping is the most widely used artificial lift method for onshore oil wells. Sucker-rod strings transfer the motion from the driving machine on the wellhead to the downhole oil pump. Pump diagnoses are generally conducted through an interpretation of the pump dynamometer graph (pump card). View Details
