Opis:: Cementing jobs are a very important element of drilling technology considering the completion of a given field. The selection of an appropriate recipe for sealing slurry is a challenge for the cementing services and research units. Both fresh and set slurry should meet a number of technological requirements. Various chemical, physical and mechanical properties of the ground and rock mass media to a different degree influence the technological parameters of the injected fluid. The sealing slurries have to meet certain criteria if the high efficiency of works is to be provided. The first of them is the criterion of physicochemical congruence with the environment. The second condition stems from the criterion of pumping the slurry. It is realized by selecting an appropriate rheological model and rheological parameters of the sealing slurry. The third requirement is connected with the need of providing suitable strength and durability of hardened sealing slurries as a result of the physicochemical processes. The fourth condition should account for the economy and ecology factors. The selection of recipes for sealing slurries should not be accidental or an output of unfmished laboratory tests. The correct sealing and reinforcing of the rock mass are prerequisites of further engineering works performed in the wellbore. The results of laboratory experiments on the concentration of ash from the fluidized-bed combustion of lignites on rheological parameters of fresh sealing slurries based on drilling cement class G (HSR) Dyckerhoff (API Class G HSR - Black Label) for various water/cement ratios are presented in this paper.

Opis:: This article presents a method in which low rheology drilling muds are used as a solution for demanding wellbore pressure management and high Equivalent Circulating Density (ECD) values. In order to investigate this problem series of numerical simulations were conducted. Real, field data from two already accomplished wells was used to recreate actual wellbores conditions in Halliburton Landmark Drilling Software and to calculate ECD values. In order to check and confirm the program’s results accuracy, the outcomes were compared with pressure while drilling (PWD) equipment surveys results made during drilling operations. Next, simulations were made in order to check how low rheology parameters of drilling muds will impact overall ECD values. Additionally in the article are included field tests results from Hibernia Platform, prepared by Bolivar, Joung et al. in 2007 where specially treated (TMSB) low rheology drilling fluids was used to mitigate lost circulation issues and extensive ECD values. Both researches’ results indicate that low rheology drilling muds may solve ECD optimization problems while still maintaining required properties and executing tasks of drilling fluids.

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.
