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:
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.

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.

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:
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.

Opis:
A major source of valued water are groundwater deposits. Therefore, constantly growing water demand requires greater focus on the subject of hydrogeological drilling. The primary requirements for groundwater drilling are: protection of important aquifers as well as formations being drilled and further easy removal of the mud residues during well development. Both aspects are connected to mud ingredients and additives selection. This necessitates an improvement of drilling fluid formula for most effective borehole drilling and successive exploitation. This article concentrates on the drilling fluid for hydrogeological drilling. In order to validate the practical utility of developed mud, laboratory research was conducted. An analyses of the outcomes expose the mud improving drilling process and fulfilling above mentioned requirements

Opis:
The article describes issue of a mud for hydrogeological wells and a method of removing sediment accumulated on the well filter and in the near-well zone after borehole drilling. Developed fluid formula is based on both primary criterion of selecting the best technological parameters of the mud and restrictive ecological standards. Because of the contact between the mud and the underground water (which is the main source of potable water), a need to select appropriate components such as biodegradable polymers (Guar-Gum, XC) and other organic compounds that are not causing harmful environmental effects has arisen. Furthermore, developed formula allows for relatively easy removal of mud remains from the well filter and near-well zone, inereasing well efficiency. The paper includes research findings of sediment acidizing by the procedure called "soft acidizing". Any information about practical application of this procedure can hardly be found in specialized literature. Therefore, concentrations and variations of the acetic, hydrochloric and citric acids were subject of research and analysis.

Opis:
Clay rock hydration is primary reason of borehole wall instability during drilling. In correspondence to this fact, it is substantial to counteract abovementioned phenomenon. It can be achieved e.g. applying ionic hydration inhibitors in the drilling mud formula. From the point of view of drilling effectiveness, the most practical is water based inhibitive mud. Its stabilizing properties are partially effect of soluble salts and low concentrations of polymer. This type of the mud exhibits good rheological properties and causes, in most of cases, increased rate of penetration (ROP). Ionic inhibition contribute to reduction of both dispersion and hydration of clay rock due to decreased instability of shales containing swelling clays. Hydration degree depends on the type and concentration of inhibitive ions in the drilling mud. This paper describes studies on influence of the chosen inhibitors (KCl, K2CO3 , HCOOK, CaCl2) on technological parameters of the developed drilling muds with triple inhibition system. Obtained results indicate good parameters of the mud. For HCOOK and CaCl2 increase of the inhibitor concentration causes major changes in mud parameters, however for K2CO3 and KCl those parameters do not change significantly.
