<p class="Default">Lumpur pemboran merupakan salah satu penunjang yang penting dalam suatu operasi pemboran minyak, gas dan panas bumi. Fungsi Lumpur pemboran  ditentukan oleh komposisi kimia dan sifat fisik lumpur.  Kesalahan dalam mengontrol sifat-sifat fisik lumpur akan menyebabkan kegagalan yang dapat menimbulkan hambatan pemboran (<em>hole problem</em>) dan akhirnya mengakibatkan kerugian yang sangat besar. Viskositas merupakan bagian yang pokok dalam sifat-sifat rheologi fluida pemboran. Pengukuran sifat-sifat rheologi fluida pemboran penting mengingat efektivitas pengangkatan <em>cutting</em> merupakan fungsi langsung dari viskositas. Di laborotorium teknik perminyakan penentuan viskositas lumpur pemboran biasa dilakukan dengan menggunakan Marsh Funnel.Penelitian bertujuan membandingkan hasil penentuan viskositas menggunakan marsh funnel dan viscosimeter berbasis video berbantuan <em>software tracker</em>.  Sampel dalam penelitian adalah  lumpur pemboran berbahan dasar aquadest dan bentonite dengan tambahan additive.

Sampel II  berbahan dasar bentonite ditambah aditive spersene 1 gram, Sampel III  berbahan dasar bentonite ditambah aditive CMC 0,5 gram. Sampel IV berbahan dasar berbahan dasar bentonite ditambah aditive CMC 1 gram dan sampel V berbahan dasar bentonite tanpa aditiveHasil analisa menggunakan Marsh Funnel dalam penentuan viskositas lumpur pemboran dimana dari hasil analisa laboratorium apabila lumpur dasar ditambahkan  spersene  maka viskositas kinematik akan berkurang dari 29,3 detik menjadi 28,3 detik dan apabila lumpur dasar ditambahkan CMC maka viskositas kinematik akan bertambah dari 36,5 detik menjadi 38,3 detikPenggunaan viscosimeter berbasis video berbantuan software tracker dalam penentuan viskositas lumper pemboran dengan penambahan spersene 0,5 gram diperoleh nilai viskositas 0,065 ±0.02 poise, penambahan spersene 1 gram diperoleh nilai viskositas 0,052 ±0.02 poise, penambahan CMC 0,5 gram diperoleh nilai viskositas 0,087 ±0.01 poise, penambahan CMC 1  gram diperoleh nilai viskositas 0,092 ±0.03 poise. </p><p class="Default"><em>Drilling mud is one of the important supports in an oil, gas and geothermal drilling operation. The function of drilling mud is determined by the chemical composition and physical properties of the mud. Errors in controlling the physical properties of mud will cause failure which can lead to drilling problems (hole problems) and ultimately result in huge losses. Viscosity is an essential part of the rheological properties of drilling fluids. Measurement of the rheological properties of drilling fluids is important considering the effectiveness of cutting removal is a direct function of viscosity. In the petroleum engineering laboratory the determination of viscosity of drilling mud is usually done using Marsh Funnel. The research aims to compare the results of the determination of viscosity using marsh funnel and video-based viscosimeter assisted by software tracker. The sample in this study was drilling mud made from aquadest and bentonite with additives added. The experiment was carried out five times with different drilling mud compositions. Sample I made from bentonite plus 0.5 gram additive spersene. Sample II made from bentonite plus spersene aditive 1 gram, Sample III made from bentonite plus aditive CMC 0.5 gram. Sample IV made from bentonite based added CMC aditive 1 gram and sample V made from bentonite without additive The results of analysis using Marsh Funnel in determining the viscosity of drilling mud where from the results of laboratory analysis if base mud was added with spersene the kinematic viscosity would decrease from 29.3 seconds to 28.3 seconds and if the base mud is added CMC then kinematic viscosity will increase from 36.5 seconds to 38.3 seconds. The use of video-based viscosimeter assisted by tracker software in determining the viscosity of drilling jumpers by adding 0.5 grams of spersene obtained a viscosity value of 0.065 ± 0.02 poise , the addition of 1 gram of spersene obtained a viscosity value of 0.052 ± 0.02 poise, the addition of 0.5 gram CMC obtained a viscosity value of 0.087 ± 0.01 poise, the addition of 1 gram CMC obtained a viscosity value of 0.092 ± 0.03 poise.</em></p>

Due to the daily increasing demand for crude oil fuel for its various capacities of energy production and utilizations, a twin respond of exploration for more hydrocarbon reserves and drilling activities was accompanied. As a result, rate and cost of importing drilling clay (Wyoming Bentonite), a major raw material in drilling mud becomes so high that hundreds of millions of dollar is incurred on company budget (Arinkoola, et al., 2020). Thus, the Federal Government of the federal republic of Nigeria, on sensing the benefits of local content development, then clamour for its use as drilling mud. This therefore becomes the bed-rock which this paper is belt on to investigate local clay for some its properties, like viscosity-gel strength. This paper also reviews the formulation of an equivalent one barrel of a laboratory drilling mud using Irhodo bentonite. This paper report two methods and devices used to determine viscosities; the marsh funnel viscosity method using Marsh Funnel and Fann Viscosity-Gel method using the Rheometer. The result of the experiment for the determination of viscosity using marsh funnel apparatus, for both local and bentonite drilling mud, and show 27.12 and 37.17sec/qt (seconds per quart). And when additives, CMC and guar-gum were added, 27.23sec/qt, 29.47sec/qt and 23.19sec/qt and 29.47sec/qt respectively obtained.

This study was aimed to investigate the rheological properties and the possibility of nano(Na, Ca )- bentonites nanoproducts to meet the required drilling mud properties. Sepiolite (Sp) and the mixture of 2% nanoNaB with 1% Sp were collected and prepared from Irans oil Company (NIOC). The nanoclay performance evaluation involved the experimental tests of the rheological properties, filtration and gel strength. According to the results obtained from flow properties tests for the mixture, it was indicated that the mixture was not adequate to be a suitable drilling fluid. The main objective was to make stable dispersions with nanobentonite and sepiolite by using a water soluble polymer as stabilizer. The changes in the rheological properties of bentonite were investigated at various concentrations of polyvinyl alcohol (PVA) to discover the stability of the dispersions. The standard API tests were applied for drilling fluid to determine the properties of dispersions.

The new method of Christidis and E beri (2003), which determines the layer charge and charge distribution of dioctahedral smectites in bentonites is presented and is compared to the existing methods for determination of layer charge and charge distribution, namely the structural formula method and the alkylammonium method. The new method is based on the comparison ofXRD traces of K-saturated, ethyleneglycol solvated smectites with simulated XRD-traces calculated for three-component interlayering. Applications of the method include modeling of the evolution of smectite layers towards illite during diagenesis, and study of the influence of layer charge and charge distribution of smectites on important physical properties of bentonites such as rheological properties (viscosity, gel strength, yield point and thixotropy) and swelling. Smectites with layer charge between -0.425 and-0.47 to - 0.48 equivalents phfu affect rheological properties in a different way compared to smectites with higher or lower layer charge than this layer charge interval. Based on these observations a new classification scheme for smectites has been proposed according to their layer charge. In this classification scheme the term smectites with intermediate layer charge has been introduced.

<p>The unidealized of physical and rheological mud can occured when drilling on rock layers with high salt concentrations. It is therefore necessary to add an additive to balance the effect of the salt. The aims of this study is to see the effect of salt addition on various temperature drilling mud.</p><p>This research will use two types of mud with different oil-water ratio. The drilling mud will be divided into four compositions, ie LA, LB, LC, and LD. LA and LC compositions have an oil-water ratio of 80% oil and 20% fresh water. While LB and LD compositions have oil-water ratio of 75% oil and 25% fresh water. Then the study was conducted at various temperatures, ie 80 °F, 130 °F, 180 °F, 230 °F, 280 °F, and 330 °F. After observing of the physical properties and rheology of drilling mud, it was found that the effect of adding salt NaCl can improve the physical and rheological properties of mud such as density, viscosity, gel strengh, mud cake, and solid content. Conversely, the effect of adding NaCl salt may reduce the nature of electrical stability. While the increasing of the temperature can reduce the physical and rheological properties of mud and on the contrary the loss of water and mud cake will increase.</p>

Fluid Properties

About 75% of all formations drilled worldwide are shale formations and 90% of all wellbore instability problems occur in shale formations. This increases the overall cost of drilling. Therefore, drilling through shale formations, which have nanosized pores with nanodarcy permeability still need better solutions since the additives used in the conventional drilling fluids are too large to plug them. One of the solutions to drilling problems can be adjusting drilling fluid properties by adding nanoparticles. Drilling mud with nanoparticles can physically plug nanosized pores in shale formations and thus reduce the shale permeability, which results in reducing the pressure transmission and improving wellbore stability. Furthermore, the drilling fluid with nanoparticles, creates a very thin, low permeability filter cake resulting in the reduction of the filtrate penetration into the shale. This thin filter cake implies high potential for reducing the differential pressure sticking. In addition, borehole problems such as too high drag and torque can be reduced by adding nanoparticles to drilling fluids. This paper presents the results of laboratory examination of the influence of commercially available nanoparticles of SiO2 (dry SiO2 and water-based dispersion of 30 wt% of silica), and TiO2 (water-based dispersion of 40 wt% of titania) in concentrations of 0.5 wt% and 1 wt% on the properties of water-based fluids. Special emphasis is put on the determination of lubricating properties of the water-based drilling fluids. Nanoparticles added to the base mud without any lubricant do not improve its lubricity performance, regardless of their concentrations and type. However, by adding 0.5 wt% SiO2-disp to the base mud with lubricant, its lubricity coefficient is reduced by 4.6%, and by adding 1 wt% TiO2-disp to the base mud with lubricant, its lubricity coefficient is reduced by 14.3%.

We studied and investigated the various viscosimetric and rheological polymers' behaviors during this comprehensive review. The viscosities relate to the investigation of the flux, the deformation, and the polymers' elasticity; we have employed the viscosity since this plays a primordial role in the phenomena flux and implementation of the polymer. The rheology behaviors were investigated for the determination of the physical properties of polymers. The rheological properties are mostly employed for improving polymers implementation. Further, three rheological behaviors models such as Newtonian, pseudo-plastic (Power Law, Law of Tile and Cross Law) and heat-dependent pseudo-plastic (Williams-Landel-Ferry Law (WLF), Law of Tile-Yasuda and Arrhenius law) were studied.

The rheological properties of drilling fluids have an important role in providing a stable wellbore and eliminating the borehole problems. Several materials including polymers (xanthan gum) can be used to improve these properties. In this study, the effect of the local Katira, as a new polymer, on the rheological properties of the drilling fluids prepared as the bentonite-water-based mud has been investigated in comparison with the conventional xanthan gum. Experimental work was done to study of rheological properties of several gums such as, local katira gum, and xanthan gum bentonite drilling mud. Different samples of drilling fluids are prepared adding the xanthan gum and local katira to the base drilling fluid at different concentrations using Hamilton Beach mixer. The prepared samples are passed through rheological property tests including the apparent viscosity, plastic viscosity, and yield point (YP) under different temperature conditions. The obtained results show that the viscosity is increased from 5 to 8.5 cp and YP is increased from 18.5 to 30.5 lb/100 ft2, with increasing the concentration of the xanthan gum from 0.1 to 0.4. However, the effect of the local katira in increasing the viscosity and YP is lower compared with the xanthan gum, which are ranged between 5–6 cp and 18.5–20.5 cp.
