Oil-based mud (OBM), a non-Newtonian fluid, is known for its superior performance in drilling complex wells as well combating potential complications. However, the good may degrade under certain circumstances especially because of impact chemical instability at an elevated temperature. The same phenomenon occurs water-based (WBM) when it used high temperature conditions. To prevent this degradation from occurring, numerous studies on utilizing nanoparticles to formulate smart fluids...

Deviation from vertical path makes drill cuttings to accumulate on the lower side of wellbore that induces formation bed. Subsequently, relative problems occur while drilling. Excessive torque and drag, difficulties in running casing hole accomplishing good cementing jobs mechanical pipe sticking are few classical examples such problems. Therefore, a comprehensive understanding influential parameters cleaning seems be essential. This paper indicates results an experimental study was carried...

Drilling water-sensitive shale formations often leads to wellbore instability, resulting in drilling problems because of the clay's high-water affinity. To solve this problem, different nanoparticles (NPs), such as nanosilica, have been used formulate water-based muds with potassium chloride (KCl-WBM). Nevertheless, unmatched pore size pores when using nanosilica fails completely prevent swelling and dispersion. This study discusses effects KCl-WBM sodium dodecyl sulphate-treated...

In oil and gas exploration development, drilling a hole is one of the first most expensive operations. The continuous demand from industry to reduce costs operational problems has resulted in numerous innovative technologies that allow us drill directionally. Nevertheless, cleaning become problematic issue directional because cuttings tend be deposited on lower side deviated hole. Excess accumulation significantly reduces rate penetration indirectly increases cost. To improve transport...

Field experience has shown that the inefficient transport of small cuttings is a main factor contributing to excessive drag and torque during drilling deviated hole; however, very little known about behavior cuttings. This experimental study investigates effect different polypropylene bead concentrations in water-based mud (WBM) on hole cleaning, along with effects cutting size, drill pipe rotation, inclination angle. A total 160 runs were performed using an rig consisting 13 ft (3.96 m)...

Drilling fluid rheology, filtration, and lubricity are fundamental parameters that influence the efficiency ease of drilling operations. The industry is constantly exploring different research areas for stabilizing improving these at high temperatures. use additives, especially synthetic polymers, poses a threat to environment. Herein, rice husk char (RHC) was used synthesize graphene Nanoplatelets (GNP) whose surface modified with triton-X100 nonionic surfactant. Field emission scanning...

Oil and gas operators worldwide are expecting service companies to deliver integrated techniques minimize, if not prevent, drilling problems. Drilling fluids perform vital functions ensure the success of operations. The technical challenges often associated with water-based loss critical properties, such as fluid control rheology, under demanding conditions, in deeper, high-temperature high-pressure wells. Fluid during operations has a very significant effect both reservoir formation damage...

Prior to embarking on mobile learning, it is critical for learning institutions research the area of finding right ingredient learners by firstly seeking whether they are ready adapt mobility learning. Adding a Malaysian perspective, purpose this paper was present quantitative study university students’ readiness integration technologies in education system within their institutions. The carried out 11 public universities Malaysia, whereby 55 questionnaires were randomly distributed students...

Drilling operation produces two major wastes which are produced water and drilling waste. The waste must be properly managed to ensure no impact the environment human. environmental human effects of exposure discussed in paper. Different type fluids has different composition, influence fluid. Due potential human, there regulations by host government international conventions for management. Generally, oil based fluid is not permitted offshore disposal drill cuttings require treatment before...

Abstract Hole cleaning is always a problem, particularly during drilling operations, and fluid plays an important role in transporting drill cuttings through annular section of wellbore to the surface. To transport cuttings, water-based mud with added polypropylene beads was selected since it environmentally friendly cost efficient. The help by providing additional buoyancy force that lifts surface via influence collision drag forces. This experiment performed using 20 ft test section, 10...

Insufficient hole cleaning, cutting suspension, clay swelling, and filtrate invasion of the formation might result from inadequate drilling mud properties. For effective wellbore stability, water-based (WBM) rheology, lubricity, filtration, shale inhibition must be optimized controlled. WBMs react with clays cause time-dependent borehole issues, which is their principal drawback. Moreover, prolonged exposure destroys certain WBM components, resulting in minimal These indicate need for...

This study examined the teachers' perceptions on implementation of mobile learning via phone at schools. The sample for this comprised thirty eight teachers who were teaching Information Technology (IT) subjects from various primary schools in Penang, Malaysia. A quantitative survey was administered to respondents whereby results indicated that adoption not perceived well among respondents. Moreover, also quite skeptical about future should it be implemented their article concludes with...

Abstract Biodegradable additives are required to minimize the environmental hazards from drilling fluid wastes. This study explores feasibility of applications henna leaf extracts (HLE) and hibiscus (HBLE) as ecological benign products in water-based fluids (WBDFs). Rheological filtration characterizations were carried out on WBDFs detect effects different concentrations (1, 2, 10, 20, 30, 40 g) these plant at 78 300 °F.
