Fluid Sampling
DataCan is now the exclusive provider of Leutert Sampling equipment in Canada.
The Company Friedrich Leutert GmbH & Co. KG was founded in 1941 by Friedrich Leutert, a watchmaker by trade, and a gifted engineer. Most of the early instruments for the oil and gas industry, and chronometers as well as navigational instruments for the shipping industry were designed by him. He quickly established the company as a major provider of subsurface and surface instruments mainly for the upstream oil and gas industry in Europe.
Positive Displacement Sampler
Leutert has been manufacturing bottom hole samplers since the early 1950s. Our latest product, the Bottom Hole Positive Displacement Sampler, has found universal acceptance and success in worldwide oilfield locations. The PDS system provides clients with representative samples of well fluids which can be transferred on location to the sample bottle without the use of mercury. The samples, when analysed, may provide data vital to the economic and technical evaluation of the reservoir.
Features
* Shortest sampler of its kind available in the market
* Confirmed sample volume (600 cc)
* Ability to operate in hostile well conditions
* No risk of contamination prior to or after sampling
* Adjustable sampling duration
* Mercury free transfer to shipping bottle
* Positive locking after tool closure
* Ability to validate sample in sample chamber
One Phase Sampler
The Leutert Positive Displacement Sampler provides clients with representative samples of well fluids all over the world. The collected fluid can be transferred on location to the sample bottle without the use of mercury. The modified version of the PDSshort, the One Phase Sampler OPS, allows the sample to be pressurized above reservoir pressure after it has been taken from the reservoir. This compensates any temperature induced pressure drop (e.g. as the sample is returned to surface) and maintains the sample in single phase.
Features
* Shortest sampler of its kind available in the market
* Considerable sample volume (600 cc)
* Maintaining the sample in single phase
* Less seals due to reduction of nipples
* Mercury-free transfer to shipping bottle
* Positive locking after tool closure
* Ability to validate sample in sample chamber
Nitrogen Booster
The Leutert One Phase Samplers and Cylinders allow over pressuring the samples after they“re removed from the reservoir. The Sample chambers are pressurized across a piston with a nitrogen gas chamber. This compensates any temperature induced pressure drop (e.g. as the sample is returned to surface). The Leutert Nitrogen Booster Station is used to compress nitrogen into the sample chambers of the One Phase Samplers and Cylinders to a pressure rate above the well pressure.
Flow Through Sampler
The PNL is a flow-through type sampler used to secure fluid and gas samples under reservoir conditions of temperature and pressure and bring them to surface for PVT laboratory test. This is achieved with the Leutert sampler PNL by using a stainless steel tube through which oil and gas may flow whilst lowering the instrument into the well to the desired sampling depth.
The PNL is then closed mechanically by either a jar head, clock tripping mechanism or an electric motor trigger. The sampler is then pulled back to surface and the trapped sample may be evaluated in PVT laboratory analysis.
For safe transportation of the sample obtained by the PNL, it is usually required to transfer the sample into specially designed shipping bottles. For this procedure, Leutert also supplies the bottles, a high pressure mercury pump and all other necessary tools and instruments.
Sampler Clock
The Sampler Clock has been designed to activate the Leutert bottom hole samplers PNL and PDS/OPS. Samplers with different pressure ratings may employ the same clock. Even other downhole tools such as callipers may be activated by the clock. The clock is of extremely rugged design to resist vibration, shock and temperature extremes encountered in oilfield and geothermal operations.
They are not sensitive to bumping and jarring, f. ex. one chosen at random (without special grooming) has been allowed to fall 1000 times from a height of 1 meter (39.4") without visible damage or impairment to its function.
Clock ranges are available in different hours of total shut-off time. The winding key allows setting of partial times of respective total time of the clock.
Piston Type Sampler Cylinders
The Piston Type Sample Cylinders PDC and OPC are shipping bottles designed to transport and store pressurized samples, especially hydrocarbon samples.
To separate the sample fluid from a secondary driving fluid, the bottles are equipped with a floating piston. A mixing ball is also incorporated in the bottles. The bottles are designed with a minimum of dead volume.
The two end caps are sealed with double O-ring seals and back-up rings. The piston has a single O-ring seal and a wear ring and is designed to minimize friction and reduce pressure load. The bottles are equipped with right angle needle valves with ¼" NPT female port connections on both sides. On the sample side there is also an evacuation port nipple and plug.
The bottles are further equipped with protectors on both ends for protecting valves and threads during handling and transportation.
A fiber glass or aluminum transportation box is available.
Surface Sampling Bench
The Leutert Surface Sampling Bench SSB is used to take surface samples from the test separator during production testing of oil and gas wells. Samples of the separated fluids are taken simultaneously. The oil is collected in a piston type sample cylinder while the gas may be collected in one of the Leutert gas sample cylinders. In the laboratory, oil and gas are recombined for further analysis. The SSB is suitable for carrying one piston type oil sample cylinder and one or two Leutert gas cylinders.
A representative sample can be taken only, if the well conditions are stable during sampling. Unfortunately, small changes may occur within short periods of time. These changes may affect the equilibrium in the separator and, therefore, affect the composition of sampled fluids. The chance for changes appears to rise with the time it takes to take the required samples. Using the Leutert Surface Sampling Bench ensures that the samples may be taken in a very short period of time. Within this time, changes in the equilibrium are unlikely to appear and a representative sample may be taken.
Gas Sample Cylinder
For every PVT analysis, a true representative sample is required. Such samples may be taken from the well test separator during production testing operations. Gas, oil or condensate are collected separately at the same separator conditions. Later, the components are recombined for PVT analysis in the laboratory. In this case, Leutert Gas Sample Cylinders with a large capacity of max. 20 liters ensure sufficient gas from a single sample for a complete PVT recombination study.
The Gas Sample Cylinder is made from aluminum for strength, corrosion resistance and metal fatigue resistance. It is also lighter than comparable steel cylinders making it easy to handle and cheaper to transport.
This special valve design allows to operate the Leutert Gas Sample Cylinders like conventional double ended Gas Sample Cylinders. In comparison to the average double ended Sample Cylinders, the Leutert Gas Sample Cylinder has the advantage of a stable base which makes its handling easier.
Sand Sampler
The Leutert Production Sand Sampler is used to collect physical samples of sand from the flow line of a well. The sampler is used by many oil companies due to its reliability. The volume of collected sand is representative and allows calculating the sand volume produced by a well. Sand samples should be taken from all wells routinely to determine which wells are causing sand build-up.
The flow-through sand sample cylinder is equipped with one inlet respectively outlet valve on each end and an integrated mesh of different mesh sizes. The cylinder tube can be separated into two parts and the mesh may be changed. By changing the mesh size, a maximum of sand can be filtered without causing high pressure in the device by blocking the pores. The inlet valve of the sample cylinder is fitted with a rupture disc for any unforeseen pressure build-ups.
