Opis:: While reconstructing partially exploited boreholes located in south-eastern part of Poland there were several issues. Standard procedures were not efficient enough to fulfil the requirements for fluid to work properly. This enforced investor to turn to the Faculty of Drilling, Oil and Gas AGH UST Krakow for assistance in developing special formula for working fluid. Major requirements set for reconstruction fluid were to: inhibit hydration of loam rocks, reduce corrosion of casing and tubing and decrease filtrate loss which maintained at a high level. Therefore, the Faculty of Drilling, Oil and Gas AGH UST Krakow developed and compared various reconstruction fluids' formulas to eliminate encountered complications. The article also concentrates on studying the samples collected from the borehole and presents conclusions based on laboratory tests. Analyses of the research results expose best working solution for eliminating the issues that came across during reconstruction of the borehole.

Opis:: Controllable fluids (smart liquids) are the substances that change their properties under the influence of external physical fields. Changes of these liquids properties take place in a controlled manner and they are fully reversible. The ability to changing nature of work is a very important aspect that determines their vast application possibilities. It also makes they are occupying significant place in the modern engineering. Content of this report has been in turn devoted to systematization information on the properties and work of magnetically activated controllable fluids. There have been highlighted some commonalities and differences between two basic types of magnetic fluids (ferro- and magnetorheological fluids). Essential areas of controllable fluids application and their production methods have also been presented within this notice. It seems to be more than reasonable to explore this title issue using new methods of research and observations. They in fact directly create another chances for discovery unknown features or simply adapting the existing ones to current technical expectations. What are also important, smart liquids can be threaten as highly advanced materials which synthesis cover manipulation on the already known substances and do not cause any environmental pollution. Discovered over sixty years ago, they still signalize a great potential to development.

Opis:: Clay shale rocks large intervals drilling generates a serious issues caused by hydration, swelling and dispersion of clay rock. Those reactions might lead to break-downs and complications in drilling as the consequences of borehole wall stability loss that have source in cave effect (occurrence of caverns and cavings) and borehole diameter sharp decreasing. Therefore, the outcomes of the research that have been undertaken are muds formulas adjusted for drilling various clay rock intervals.

Tematy:: drilling fluids
underbalanced drilling
Opis:: This paper describes a research finding of drilling mud designed for UnderBalanced Drilling. The UnderDril mud formula is based on a low number of compatible components, therefore it enables uncomplicated adjustment of its technological parameters to specific conditions and contributes to the reduction of its application costs. Moreover, the UnderDril mud is composed of biodegradable ingredients, that results in a beneficial effect on the possibility of its utilization and simultaneously makes it hazardous free for the environment. The conducted research showed that the abovementioned mud can find an industrial application.

Opis:: An unsteady MHD two-layered fluid flow of electrically conducting fluids in a horizontal channel bounded by two parallel porous plates under the influence of a transversely applied uniform strong magnetic field in a rotating system is analyzed. The flow is driven by a common constant pressure gradient in a channel bounded by two parallel porous plates, one being stationary and the other oscillatory. The two fluids are assumed to be incompressible, electrically conducting with different viscosities and electrical conductivities. The governing partial differential equations are reduced to the linear ordinary differential equations using two-term series. The resulting equations are solved analytically to obtain exact solutions for the velocity distributions (primary and secondary) in the two regions respectively, by assuming their solutions as a combination of both the steady state and time dependent components of the solutions. Numerical values of the velocity distributions are computed for different sets of values of the governing parameters involved in the study and their corresponding profiles are also plotted. The details of the flow characteristics and their dependence on the governing parameters involved, such as the Hartmann number, Taylor number, porous parameter, ratio of the viscosities, electrical conductivities and heights are discussed. Also an observation is made how the velocity distributions vary with the rotating hydromagnetic interaction in the case of steady and unsteady flow motions. The primary velocity distributions in the two regions are seen to decrease with an increase in the Taylor number, but an increase in the Taylor number causes a rise in secondary velocity distributions. It is found that an increase in the porous parameter decreases both the primary and secondary velocity distributions in the two regions.

Opis:: Undermentioned article presents how wellbore trajectory changes may impact mud flow pressure losses in wellbore annulus and overall Equivalent Circulating Density (ECD) value. In order to investigate this topic, there were conducted two series of tests. In the first round actual, field data from six previously drilled wells was used to recreate real wellbores conditions in Halliburton Landmark Drilling Software and to calculate ECD values. In order to check and confirm the results accuracy, the outcomes were compared with pressure while drilling (PWD) equipment surveys’ results made during drilling operations. Next it was analyzed how ECD parameter's values change in particular sections of vertical and horizontal wellbores, due to trajectory angle modifications. With aim of expanding scope of the work, the second group of tests was made in Drilling Fluids Laboratory at Faculty of Drilling, Oil and Gas. Using Grace Sagging Tester M8500 Ultra HPHT it was examined how in wellbore conditions (high pressure and temperature) wellbore trajectory angle modifications may impact solids sedimentation process and fluid density changes in the annulus thus ECD value as well. The results indicate that there is a relationship between wellbore trajectory angle changes and ECD value shifts. In addition there are included field tests outcomes prepared by K&M Technology Group which confirm presented assumption.

Tytuł:: Complex reservoir drilling fluid solutions for reservoir drilling

Tematy:: drilling fluids
reservoir drilling
Opis:: Drilling into a pay zone with a conventional fluid can introduce a host of previously undefined risks, all of which diminish reservoir connectivity with the wellbore or reduce formation permeability. This is particularly true in horizontal wells, where the pay zone can be exposed to the drilling fluid over a long interval. Selecting the most suitable fluid system for drilling into the pay zone requires an understanding of the reservoir. Using data generated by lab testing on core plugs from carefully selected pay zone cores, a reservoir-fluid-sensitivity study should be conducted to determine the morphological and mineralogical composition of the reservoir rock. Natural reservoir fluids should be analyzed to establish their chemical makeup. The degree of damage that could be caused by anticipated problems can be modeled, as the effectiveness of possible solutions for mitigating the risks. In addition to being safe and economical for the application, a Reservoir Drill-In Fluid should be compatible with the reservoir's native fluids to avoid causing precipitation of salts or emulsions production. A suitable nondamaging fluid should establish a filter cake on the face of the formation and shouldn't penetrate too far into the formation pore pattern. The fluid filtrate should inhibit or prevent swelling of reactive clay particles within the pore throats. Formation damage commonly is caused by: – Pay zone invasion and plugging by fine particles. – Formation clay swelling. – Commingling of incompatible fluids. – Movement of dislodged formation pore-filling particles. – Changes in reservoir-rock wettability. – Formation of emulsions or water blocks. Once a damage mechanism has diminished the permeability of a reservoir, it seldom is possible to restore the reservoir to its original condition.
