Casing completion is an extremely important part of the process of drilling and completing an oil well. This paper aims to focus on measuring corrosivity caused by drilling mud on casing materials using a simple method.

In this experimental study a simple method is used to determine the effect of drilling mud on the two widely used casing string materials in the oil industry, carbon steel and J‐55 alloy. The drilling mud was formulated using Saudi local clay deposits, where mud viscosity at different clay concentration was measured to show the effect of clay content on mud apparent viscosity, and select the best formulation. The average weight loss of each type of steel was measured to show the corrosion rates, caused by a drilling mud formulated using collected clay samples. Viscosity measurements are shown.

Corrosion in dynamic tests is higher than in static tests, and the Saudi clay muds were less corrosive on J‐55 alloy than on carbon steel.

The assessment method is a simple and fast way to predict maximum and minimum corrosion while drilling.

Laboratory investigation of the effect of carbonate contaminant on the rheological properties of drilling mud based on Bingham plastic flow model was carried out. The rheological properties investigated were yield point, plastic viscosity, initial gel strength and ten‐minute gel strength. Eight samples of the same mud were used in the investigation. Equipment used in studying the rheological properties was a direct‐indicating viscometer. The result of the investigation showed that carbonate contaminant in drilling mud adversely increases the yield point and gel strength. Marginal increase in the plastic viscosity of the mud was also observed. The mud flocculated as the amount of carbonate increased.

The purpose of this paper is to study the tribology behavior of steel–steel contact under the lubrication of water-based drilling mud with different oleic acid-filled microcapsules as lubricant additives.

A ball-on-disc tribometer was used to evaluate the lubrication properties of the steel–steel contact. The wear tracks of the worn surfaces were observed by a scanning electron microscope.

Results show that the dependence of both friction and wear on the category of additives shares a consistent pattern. In contrast to oleic acid and empty microcapsules, oleic acid-filled microcapsules achieve the best tribological performance which is related to the lubricant effect of oleic acid and the isolation and rolling abilities of microcapsules.

This study provides a helpful method of encapsulated lubricant additives to prolong lubrication performance for steel–steel contact.

This study has applied microcapsules to improve the tribological properties of drilling mud.

The purpose of this paper is to obtain the combination of working parameters suitable for pulsating negative pressure shale shaker through simulation, which is conducive to efficient recovery of clean drilling fluid and relatively dry cuttings.

Shale shaker is still one of the main equipment in solid–solid and solid–liquid separation processes in drilling industry. This research is based on a new drilling fluids circulation treatment device, namely pulsating negative pressure shale shaker. In this work, a numerical study of particle flow and separation in the pulsating negative pressure shale shaker is carried out by coupling computational fluid dynamics/discrete element method (CFD-DEM). The effect of vibration parameters and negative pressure parameters are studied in terms of conveyance velocity and percent through screen.

The results show that, conveyance velocity of particle is mainly affected by vibration parameters, negative pressure in pulsating form can effectively prevent cuttings from sticking to the screen. Vibration parameters and pulsating airflow velocity peak have great influence on percent through screen, while vibration frequency and screen slope have influence on the time when the percent through screen reaches stability.

In this paper, the authors put forward a new kind of drilling waste fluid treatment equipment, and focused on the study of particle movement law. The results have important guiding significance for the selection of structural design parameters and rational use of equipment. In addition, the new device provides a new idea for solid–liquid separation method, which is one of the hot topics in current research.

Because much human knowledge consists of elementary fragments of know‐how, applying a significant amount of knowledge requires new ways to organize decision‐making fragments into competent wholes. Knowledge systems collect these fragments in a knowledge base and then access the knowledge base to reason about each specific problem. As a consequence, knowledge systems differ from conventional programs in the way they're organized, the way they incorporate knowledge, the way they execute, and the impression they create through their interactions. Knowledge systems simulate expert human performance, and they present a humanlike facade to the user.

The purpose of this paper is to study the influence of different factors on mud performance, find the best conditions and synthesize a new type of anti-collapse drilling polymer mud with higher stability. The anti-collapse mechanism of drilling polymer mud was also suggested.

Exploring the influence of different molecular weight thickeners, filtrate reducers, soda ash addition and film-forming components on the mud performance, so as to obtain the best ratio of anti-collapse drilling polymer mud.

The results show that the use of vegetable glue, sulfonate copolymer and vegetable fiber powder can synthesize a high-viscosity, high-stability, collapse-resistant mud. When the mass ratio of vegetable fiber powder: vegetable glue: sulfonate copolymer is 40:1:2, the mud viscosity is 21.2 s, the fluid loss in 30 min is only 12.5 mL, and the mud film thickness is 1.5 mm, which is one ideal anti-collapse polymer mud.

Compared with ordinary polymer mud and bentonite mud, this anti-collapse polymer mud not only uses vegetable glue instead of traditional tackifiers but also effectively uses vegetable fiber powder produced from waste wood, which is environmentally friendly and highly stable specialty. It can effectively improve the safety and quality of construction during drilling in water-sensitive geology.

DURING October and November 1957 B.P. Exploration Co. Ltd. made a number of trials at their Egmanton oilfield in Nottinghamshire to compare the relative merits of turbodrilling and rotary drilling techniques. Although the details of these results are not of direct interest from a lubrication point of view the part played by the drilling fluid in these techniques is worthy of note.

Disruptive technologies can significantly contribute to the sustainability of operations in the petroleum supply chain. The present study aims to identify the prime sustainable dimensions and disruptive technologies implementation in the supply chain of the petroleum industry. The authors used content analysis in the literature and experts input to explore the sustainable dimensions and disruptive technologies in the supply chain.

This study used a hybrid method of hesitant fuzzy set and regret theory to identify the prominent sustainability dimensions and prominent disruptive technologies. This method emphasizes the decision-makers psychological characteristics under uncertain environments.

The result indicates that social responsibility, labor practices, safety and technical standards hold the most prominent sustainable dimensions in the petroleum supply chain. Further, the result also depicts that when consider an equal degree of regret and rejoice, artificial intelligence and big data could significantly enhance operations sustainability in the petroleum industry.

This study considers only 11 sustainable dimensions and 43 sustainable factors, whereas other dimensions and factors could also be considered in future research. The research uses hesitant fussy set and regret set theory to identify the prominent sustainable dimensions and disruptive technologies, whereas other multiple-criteria decision-making (MCDM) techniques can also be used.

To the best of the authors’ knowledge, this is the first paper to explore the sustainable dimensions (environmental, social and economic) and disruptive technologies in the supply chain of the petroleum industry. This research intended to guide the practitioners, policymakers and academicians to emphasize their effort toward sustainable operations supply chain management.

The research assessed the development of petroleum drilling activities and its associated waste discharges in the Niger Delta environment of Nigeria. Field visits were made to 18 wells in which petroleum drilling operation was in progress. Of this number, wastes samples were randomly collected from ten wells for data collation and laboratory analysis. Results show that petroleum drilling waste types in Nigeria include cuttings, mud/chemical, oil spills, cement slurry/dust, condemned pipes, filters, and machinery parts and even noise. Pretreatment of waste in hardly undertaken by the oil prospective companies before discharge into the surrounding environment. Total dissolved solid and oil/grease values as high as 3700mg l^–1 and 1100 parts per million, respectively, were tested as effluent discharges around some of the wells studied. It was recommended that the Nigerian Government constitute a powerful environment monitoring body whose responsibility will be to ensure that the various multi‐national oil companies comply with petroleum laws and statutes of the country.

The purpose of this study is to solve the oil drill pipe joints and casing excessive wear problems and to improve the drill pipe joint-casing wear resistance and anti-friction properties.

On the surface of the drill pipe joints using oxyacetylene flame bead weld (BW) wear-resistant welding wire ARNCO-100XT^TM prepares welding layer, high-velocity oxygen fuel (HVOF) Cr₃C₂75-NiCr25 prepares coating and subsonic flame spray and remelt (SFSR) Ni60 prepares coating, then comparing and analyzing the friction and wear of the three types of wear-resistant layers and the casing under the condition of 1.8 g/cm³ mud drilling fluid lubrication. The wear resistance and anti-friction performance of the drill pipe joints were evaluated based on the wear situation, finally revealing its friction and wear mechanisms.

Three types of wear-resistant layers can improve the surface wear resistance of drill pipe joints, the wear-resistant layer and the substrate are well combined and the welding layers and coating are both dense and uniform. The wear resistance of the HVOF-Cr₃C₂75-NiCr25 coating is 10.9 times that of the BW-ARNCO-100XT^TM weld layer, and the wear resistance of the SFSR-Ni60 weld layer is 2.45 times that of the BW-ARNCO-100XT^TM weld layer. The anti-friction properties of SFSR-Ni60 welding layer is the best, followed by HVOF-Cr₃C₂75-NiCr25 coating, and the anti-friction properties of BW-ARNCO-100XT^TM welding layer is the worst among the three.

The research results of this paper have great practical value in the process and material of improving the wear resistance and anti-friction performance of the drill pipe joint casing.
