The aim of the project is to develop a new, ’stand alone’ (the hidrate inhibition task is performed individually) technology which ensures the producibility of gas wells with different production rate and gas compisition. The prototype of the control system of this technology is also the part of the development.
The developed monitoring system will be able to operate properly with the gas industry technology without human intervention. During this, the operators will be able to ask for the state of the feeding system and the technological parameters of the wellbore zone by a pre-programed schedule or by a call which can be made anytime. The RIAES of the University of Miskolc was a partner in the fulfilment of the project
Due to the low amount and the good decomposition properties of the chemical, no recycling technology should be developed instead of the methanol regeneration, therefore, the installation of the stand alone type feeding systems to the wellbore zone should be realized.
The developed equipment is suitable for measuring conventional (based on Darcy’s law) and non-conventional (pulse decay-PPD) axial permeability with water or gas. The pore pressure and the mantle pressure are assured by high precision pressure generators, which can be programed. The flooding of the examined rock sample can take place by acidic and basic (alkaline) solutions or petroleum (kerosene)
The device can be used mainly for examining very tight rocks, based on Jones’ theory (1997). A filter can be mounted on the inlet and the outlet side, between 0.5 and 230 microns. The permeameter has a high pressure saturation cell suitable for sample saturation. It is also equipped with a flooding cell for the non-water permeability measurements (brine, oil). After the saturation, the permeability of the very tight rocks can be measured in a short time (max. 1 day) with the PPD theory. The measurement can be repeated, and during the measurement the stress on the rock is low (e.g. 1 bar differential pressure between the inlet and the outlet side). The uncertainty of the measurement can also be estimated.
• Max. mantle pressure: 350 bar
• Max. pore pressure: 320 bar
• Differential pressure interval: 0,01-30 bar
• Measurement temperature interval: 20-150 °C
• Flow rate: 0,01-10 nl/min
• Sample diameter: 1" és 1.5"
• Sample length: max.: 3"
The aim of the project is to establish a grid type, sensor based, remotely controlled mobile measurement system which is suitable for the the continuous monitoring of the surface water quality properties and acts as an online information collection and service system.
As a result of the project, and integrated, scalable, mobile, expandedly reachable complex service pack which is developed for the user profiles whose main elements are the following:
o Objective and model based measurement method to determine the water quality, the predictive selection of the necessary measurements.
o A flow examination reference laboratory environment which is suitable to model the process and to ensure the reproducibility between the influential factors of the water quality and the parameters.
o Measurement equipments based on sensors and a grid-type measurement network built from them.
o A modeling software which supports the enviroment state evaluation.
With the model equipment developed as a part of the project framework, examinations can be performed on an operating well with the anti-agglomeration (AA) products at real conditions. The result of these, may assure convinvingly that these products – as they are effective and environmental friendly – are suitable for replacing the methanol, which substance is conventionally used at gas wells for hydrate inhibition.
With the measurement equipment located in the container and putting this container into the given wellbore zone, the examinations can be performed significantly faster and more effectively. The RIAES of the University of Miskolc was a partner in the fulfilment of the project.
The task in the project was to develop an automatic online water quality analyzing and monitoring system for inspecting water treatment technologies and monitoring of surface water quality. This technology is widespread in the practice, it was used even in the 1980s both in Hungary and in the countries of the European Community.
The aim of the development of the application was to establish a measurement network which ensures access for the user to integrated, modern measurement stations based on a robot analyzer via the suitable informatic system. The accredited operation of the water quality measurement station (accredited laboratory, expert staff) and the informatic systems ensure the objectively documented monitored data in the system center.
After the test operation and the test measurements, the manufactured equipment was put into operation in Devecser, by the brookside of the Torna Brook for continuous monitoring.
The PVT-MIVI 1000/230 type equipment is suitable for synchronous determination of PVT and viscosity, and for the determination of only PVT on higher pressures. The PVT cell is located in an air thermostat. During the development of the cell one of the main goals was to ensure the smallest dead volume. Due to the effective mixing, a Hg threshold was put into the cell. The bottom of the cell can be disassembled.
The most important characteristics of the cell:
• Pressure: max. 1000 bar
• Volume: max. 1000 cm3
• Temperature: max. 230 °C (The cell only be used at the maximum 230 oC temperature range if there is no MIVI in the heated space.)
The PVT-MIVI 1000/230 equipment is basically different from the systems generally used in the PVT measurement practice, because by locating the viscosity measurement unit in the PVT cell, the gas phase volume and the liquid space viscosity can be determined continuously. This innovative solution makes this equipment unique among the PVT measurement systems.
With the mercury porosimeter, the rock sample is saturated by mercury at laboratory temperature with gradually increasing the pressure to pmax.=4000 bar. On the basis of the VHg=f(p) function, the pore size distribution vs. density and distribution functions can be drawn up, and the specific surface area distribution as well.
Water-air, water-oil capillary pressure function measurements are performed by a special centrifuge, where the centrifugal force is responsible for the adequate displacing capillary pressure.
Especially for tight rock samples, it is of importance to know the capillary threshold pressure, i.e. the pressure value should be measured where the displacement of the wetting fluid begins, this is the capillary pressure of the biggest pore throat of the sample core. Knowing the threshold pressure is also important if the evaluation of underground gas storages occurs.
Under increasing and/or decreasing effective rock stress, the pore volume of the rock samples alters, thus, their porosity as well. To measure this alteration, a special equipment is needed, even at hydrostatic loading conditions when the effective rock stress is equal from all directions.
A much more complex equipment is needed if the pore volume and porosity alteration are needed to be measured under two axis (horizontal and a different magnitude vertical) effective rock stress at laboratory loading conditions. Our own developed equipment is suitable for measuring max. 100 mm diameter rock sample cores. diameter, 2” length
From reservoir rocks, the oil displacement measurements can be performed by the injection of liquid or gas state fluids (water displacement = oil displacement of oil, EOR methods). The examination of the displacement process can be performed at laboratory and reservoir conditions on small (D=1-1 ½” and l~2 ¾”), medium size (D=1-1 ½” and l~8 ¼”) or long (D=1-1 ½” and l~40”) rock samples from the reservoir,but can also be performed on different size (diameter, length) sand beds as well. In case of a special need, the displacement process can also be examined in radial flow system.
The condition analogous to the reservoir conditions (Tmax=200 0C and pmax=500 bar) can be assured by own developed equipments. The methodology of the process and interpretation of the displacement measurement data is an own development of our Institute.
