Opis:
While drilling a well using rotary drilling method with drilling mud application, permeability damage of aquifer layers in near-well zone takes place. It is caused mainly by inflow of both solid phase and filtrate originated from the mud into pores or fractures of drilled rock. In consequence of this phenomenon, pressure drawdown increase and well hydraulic efficiency decrease can be observed, what leads to exploitation capacity diminution. For the reparation of formation damaged permeability in near-well zone, new agent for disintegration of clay minerals called SKINAUT was developed at the Drilling, Oil and Gas Faculty of AGH-UST Krakow. In order to confirm its effectiveness in industrial conditions, it was conducted test of well activation for water intake from loose formation. Applied agent allowed to counteract the clogging of pore spaces and to reduce the hydraulic resistance of well thereby decreasing pressure drawdown and considerably improving well efficiency.

Opis:
The operation of water supply networks basically relies on the ability of supply water, which in the case of groundwater intakes, is defined by usable reserves offered by the wells involved. Their establishing is the last stage of an investment, i.e. building of groundwater intakes, and their value determines the type of infrastructure and technological hardware in the wells. Owing to the fact that the usable groundwater reserves are conditioned by a number of factors (economic, technological, environmental) their correct determining depends on the correct definition of the number and quality of measurements and hydrogeological observations. In practice, these measurements tend to be shortened to minimum (test pumping) or discarded (diagnostics of well construction) for financial reasons. As a result the user obtains either over- or underestimated information about the intake parameters. Exploitation of a well with overestimated capacity brings about serious technological and economic consequences, starting from the lowered productivity (drop of water table, lower yield), change of chemical composition of water, sanding up of the well as well as well failures and damage. The use of a well with underrated output does not shorten the life of the well, though is disadvantageous for the economic reasons. The productivity of wells can be verified after a few years of controlled extraction, on the basis of which the cost of water extraction, stability of chemical composition or impact on other intakes in given work conditions. Accordingly, this is a basis for updating usable groundwater reserves of the wells. Moreover, after many years of observation of groundwater intakes, one can formulate recommendations warrantying long life of wells, rational management of pump aggregates and well renovation plans.

Opis:
Drilled wells during their operation are subject to so-called “aging” processes, which is visible in the decrease of their efficiency and increase in depression. The process, especially in case of quaternary and tertiary waters, is most affected by the chemical colmatation of the filter and filter-adjacent zone with chemical compounds precipitated from the flowing water. The literature analysis shows that ferrous sediments are the main mass of sediments clogging the quaternary and tertiary water intakes. They are usually in the form of soft reddish-colored sediments, and their essential element is Fe2O3 and FeO. Iron, siderite and quartz hydroxides were also found. The degree of colmatation in such wells can be significantly reduced by frequent renovations with chemical methods. The article presents results of laboratory tests on dissolution of sediments clogging withdrawal well filters with sodium dithionite (Na2S2O4) and sodium pyrosulphite (Na2S2O5). Representative samples were taken from selected quaternary water intakes in northern Poland.

Opis:
During the drilling process, between the drilling bit that ruins the rock in the bottom-hole and the energy source located on the ground surface is the drillstring that has certain length and small cross cuts that define the dynamics of the drilling bit work. Along with the development of science, for optimization of drilling processes were developed and continue to be elaborated mathematical models that use empirical dependencies based mainly on laboratory data which are very far away from the real conditions of well construction and fail to take into account all the peculiarities of this process. Thus, the management of the drillstring dynamics related to an increase in the effectiveness of deep directional and horizontal wells drilling process through the minimization of torsional and longitudinal Iow frequency vibrations of drilling instrument is a matter of topical interest nowadays.

Opis:
One of the most important sources of water for communal purposes in the Lublin area are the useful groundwater aquifers intaken with deep drilled wells. Such wells should be highly efficient and localized in a close vicinity of the local water supply network to lower the cost of transport. Large amounts of water can be produced by large diameter wells, where heavy duty pump aggregates can be installed. High rates of penetration cannot be obtained if the profile abounds in hardly drillable carbonate. This elongates the time of drilling and increases negative impact of mud on the near well zone of the aquifer. It also lowers hydraulic parameters of the well. To improve the efficiency of the wells, drillability tests with cogged bits were performed in carbonate rocks to optimize the mechanical parameters of drilling. Measurement sections, each 0.3 to 0.5 m long, were selected for the tests. Each section was drilled at constant rotational speed and weight of bit values. Prior to the drillability tests, the limits on the weight of bit and rotational speed of the bit were established, in line with the technological characteristic of rig Wirth B3A, strength of the string and of the cogged bit.

Opis:
Use of deep water-bearing horizons on an industrial scale is an expensive undertaking, mainly in the first phase of the project which is the well construction stage. Also, emergencies occur during the well operation, with the most frequent including yield reduction caused by the poor technical condition of the well. These 17 frequently lead to the total decommissioning of the well, caused, for example, by backfill, filter damage or casing pipe damage. After conducting the proper diagnostics, a decision is most often made in such cases to reconstruct a well, and much less seldom to drill a new well hole. Reconstruction of water intake wells usually encompasses replacement of the entire filter column with the well filter damaged as a result of ageing. As new technologies and materials become available on the market, it is possible to use new generation filters in the well construction, with better technical parameters (in terms of strength, hydraulics and corrosion resistance). In many cases, it allows for maintaining or achieving similar operational parameters in the reconstructed well. The determination of resources for a reconstructed well should, however, take into account modified filtration conditions in the aquifer’s zone adjacent to the filter because of the zone siltation during previous use of the well. The paper includes an evaluation of the impact of the reconstruction of two wells extracting water from the Lower Cretaceous level on improvement of their yields.

Opis:
Most of the useful aquifers in Poland occur in the Quaternary and Tertiary horizons, which are deposited at a depth of tens to hundreds of meters. Owing to the need of providing large quantities of water for municipal and industrial purposes, the aquifers are more and more frequently opened with large diameter wells of various designs. Such wells are mostly drilled with the rotary method with reverse mud circulation with the use of various bits. The Quaternary and Tertiary strata abound in loose and weakly consolidated rocks therefore cutter bits are predominantly used. They allow for high rates of drilling and shorter time of drilling of the well. This significantly influences the negative influence of drilling mud on the near screen zone of the aquifer and better hydraulic properties of the well. Drillability tests were performed with cutter bits of 0.86 and 0.67 m diameter for providing high rates of drilling of large diameter intake wells in loose and weakly consolidated rocks. The research was made for measurement sections 0.5 to 1.0 m long, and each of them was drilled at con- stant rotational velocity and axial weight on bit. Prior to the drillability tests the limitation of weight on bit and rotational velocity of bit imposed by the technical characteristic of Prakla B50 rig, strength of the string and butter bit were established. Various regression models were analyzed for the sake of finding a dependence between drilling rate and axial weight on bit and rotational velocity of bit for particular macroscopically homogeneous layers. The best results were obtained for the exponent model illustrating the influence of axial weight on bit and rotational velocity of bit on the drilling rate, which has been proved by the calculated regression coefficients and statistical parameters.

Correctly performed intake wells are a warranty of long and efficient exploitation of the object. A number of important factors are involved, starting from the correct technology of drilling to proper supervision of the investor and control of realization of particular stages of work. These factors are typical of each stage of the investment process, from the stage of determining project requirements, quality of drilling to commissioning of the well. For this reason it is extremely important for the investor to establish the requirements and technical criteria which will be presented to the authors of the geological project and potential performer of the well. Geological works can be successfully verified with available diagnostic techniques, thanks to which the quality of performance can be recognized, make the contractor remove construction failures and improve the efficiency of hydraulic well before final commissioning. The necessity of performing such an analyses should be included in the budget of the planned well.Properly defined technical condition of the drilled well and evaluation of its hydraulic efficiency, being a basis for commissioning, allows the designers to select rational parameters of production and elongate a well’s life.

Laslau Mare is a mature gas field in Transylvania Basin. The field exploitation began in 1975 and has been operated since then by Romgaz. In 2004 Romgaz entered into an Association agreement with Schlumberger to rehabilitate Laslau Mare field. Association’s main goals for project rehabilitation has been maximization of field potential by increasing gas production and reservoir ultimate recovery factor. The incremental production, defined as the additional gas volume obtained above a production baseline negotiated at project inception is the key objective of Association. According to Project Management Body of Knowledge (PMBOK®) framework from the Project Management Institute (PMI), the project management breaks in processes groups, knowledge area and professional and social responsibility all of them being integrated in a system approach. This paper examines key aspects of the project management system processes, adapted to the oil and gas industry and implemented in our project to meet and exceed project goals.

Opis:
The technology of CO2 sequestration is connected with the necessity of drilling wells, which construction is adapted to aggressive CO2 rich environment. Recipes of cement slurries, used nowadays in carbohydrates production wells, are prepared without considering corrosion occurrence caused by affection of acidic environments originating from carbonate acid radicals. Although increased resistance to sulfates is typical for these cements, this does not guarantee any resistance to corrosive effects of CO2. Density, fluidity, filtration, Marsh Funnel viscosity and rheological parameters measurements (with a twelve‑ranged viscometer FANN) were carried out. Using Rheosolution Software, a proper rheological model for each recipe was matched. Corrosive effect on cement rock was obtained through keeping samples in pressure tanks containing compressed CO2 for the period of 180 and 360 days. Directly after taking the samples out of the tanks, flexural and compressive strength tests were carried out with the use of hydraulic press. The results were compared and differences between the samples from CO2 and samples taken from water environment according to API recommendations were presented. The corrosion effect on the samples from both environments was presented with microscopic images. Lengthening of the slurry thickening time and improvement of the slurry fluidity were obtained thanks to adding the third generation superplastifier produced by BASF Polska Sp. z o.o. As a research result a slurry recipe of the best strength has been developed. It can be used for proper sealing in CO2 sequestration well technology

A group of innovative recipes of slurries to be used for sealing wellbores in shale formations were worked out. Both fresh and hardened cement slurries should meet restrictive technological requirements, therefore this issue was in the focus of the conducted research. Laboratory experiments were performed on high-class research and control/measurement equipment, thanks to which innovative recipes of cement slurries for sealing casing in shale gas formations could be worked out. These recipes comply with standards and can be successfully used as read-made applications for sealing casing installed in shale formations.

downhole water sink
Opis:
It is well known that water coning is a difficult-to-solve problem in heavy oil reservoirs with bottom water. A promising solution is offered by the downhole water sink (DWS) technology – a dual well completion technique for water coning control in reservoirs with bottom aquifer. In the field case addressed in this study, a DWS well was installed in a heavy oil reservoir underlined by thin water zone – notorious for severe water coning problem. Initially, the two well’s completions had no separating packer; Later, the well was recompleted with packer and displayed much improved oil productivity and water coning control. However, after accidental shutdown of the bottom (water sink) completion and continuing production from the top (oil pay) completion the well was rapidly watered out and shut down. In this study, the well’s production history is analyzed to better understand dynamics of water coning control with packer-less DWS and the effect of temporary water sink shut-down. The analysis is performed with a radial grid-based simulation model using the reservoir properties and well production data. An adequate history match is achieved by tweaking reservoir properties within their uncertainty range – mostly the relative permeability and capillary pressure curves. The packer-less completion displays steady invasion of water to the top oil completion through the gravel pack with no separating packer. The analysis also confirms detrimental effect of sole temporary shutdown of the water sink (bottom) production that caused rapid buildup of water saturation in the oil pay zone around the well. This work also evaluates possible restoration of oil productivity by putting the well back on production after a dormant period of time (when water cone might subside) and the contribution of the bottom water drive (aquifer strength) to the restored productivity. A 25-year production performance forecast is performed for three scenarios of well’s operation after the water sink completion’s shut-down for one month: (a) no shut-down and continuing production as DWS well; (b) one-month shut down and conversion to a conventional single-completed well; (c) one-month shut down and continuing production as DWS well. The results reveal that the watered-out well could be revived as an oil producer only by restoring its DWS operation [scenario (c)] as the conventional well operation [scenario (b)] would produce only water. Moreover, detrimental effect of temporary water-sink shut down would irreversibly reduce well's productivity by more than 10 percent. It is also shown that stronger aquifer stimulates DWS well productivity improvement of up to 20 percent in case of strong bottom water drive.

Opis:
Sustained casing pressure (SCP) represents a major issue because of its large scale occurrence and risks to health, safety, and the environment. Present regulatory assessment of sustained casing pressure is mostly qualitative with implicit risk formulation. It currently holds that wells with casing head pressure that can be bled-down to zero and is followed by slow 24-hour pressure buildup are below acceptable level of risk. This study introduces new quantitative metrics of well integrity loss risk - the instant cement sheath leak rate of 15 scf/min (barrier integrity), and the total annual environmental gas discharge of 6 tons of volatile organic compounds (VOC) per year. Field data from 19 wells reportedly affected by sustained casing pressure (SCP) are examined with a SCP testing software to assess whether or not wells with pressure that is able to bleed to zero would meet the proposed criteria. Using modeling and software tools developed by Xu and Wojtanowicz (2001) and Kinik and Wojtanowicz (2011), it is determined that three of the 19 wells (15.8) examined would fail the instant leak rate criterion. On the total discharge criterion, assuming the wells' annuli above the cement top filled out with seawater, it was also found, again, that 15.8 percent of the wells would fail the total environmental discharge criterion. Moreover, for the worst-case scenario of absolute open gas flow (empty annulus above the cement top), five of 19 wells (26.3) would fail the criterion. It is shown that - statistically, the bleed-down of casing pressure to zero gives a 90-percent confidence of the well passing the proposed criteria. Furthermore, no clear correlation was observed between pressure build-up and the barrier integrity or the environmental gas discharge criteria, thus questioning the 24-hour pressure buildup relevance as a risk indicator.

Opis:
Rehabilitation operations are applied to mature gas field, which although have a significant history production, owns a continuous energetical capacity which could be exploited in economicaly efficient conditions. For rehabilitation are selected from all the mature fields those which could additionally offer to the currently obtained basis production, a supplementary production, generated through interventions in reservoirs, wells or surface infrastructure. Although the opportunity of mature gas field rehabilitation is evident and unanimously accepted, the effective implementation of the concept represents a complex intervention. This fact is just due to natural gas reservoirs diversity, which involves developing particular models of rehabilitation, adapted to each reservoir capability. Conceptually, mature gas field rehabilitation can be divided in three sequences: reservoir, well, surface facilities. Intervention in one section or another, or concomitent intervention in all three sequences, is dictated by technical and economical reasons. Mature gas field rehabilitation must begin with main production problems identification that once recognized can be solved by remedial actions. Such corrective measures are commonly used in order to inerease the productivity of gas wells and removing restrietions on reservoir - well - surface facilities route.
