  • In this paper, the drilling tool integrating damping system is tested with Experimental Modal Analysis (EMA). The natural frequencies, the damping ratios, and mode shapes are detected. Through modal analysis testing the new damped drilling tool shows better damping ratio than the conventional tool.

  • This paper focuses on the correlation of two different marble units from an approximately 3,900 m deep geothermal exploration well (GP-1) in western Turkey by petrographical and geochemical data. Future geothermal exploration drilling in that area will benefit from a better (tectono) stratigraphic correlation and a better definition of the reservoir geometry in the basin. It is an innovative approximation in many settings to correctly correlate marble units without clear stratigraphic markers or fossil record, in particular, when sample material is restricted to cuttings.

  • Based on such analysis, additional issues should be considered while preparing future decommissioning plans and updating relevant laws in Vietnam. Particular challenges include compliance monitoring, shell mounds, drill cuttings, financial assurance, consultation with local communities and recognition of their interests, rigs-to-reefs, coastal communities’ socioeconomic development, and investment in research, training and education about oil and gas decommissioning.

  • Malunion of phalangeal and metacarpal bones are often associated with impairment of hand function and pose a challenging task for treating surgeons in most cases. When applicable, corrective osteotomy is the treatment of choice, where the affected bone is cut to correct malalignment using chisels or saws.

  • Bhoramdev seed drill is the most commonly used farm tool in Chhattisgarh. Never the less, using this plough as farm tool is labour intensive, time taking, making shallow depth and narrow cutting width. Thus, this research is initiated to come up with a solution to the aforementioned problems. Therefore, the objectives of this research were to model the basic components of animal drawn modified bhoramdev seed drill, to fabricate and test the prototype.

  • Environmental pollution by petroleum hydrocarbons (PHCs) is a severe and widespread problem impacting human health and the environment. To combat this issue, innovative and sustainable treatment methods are required. This research study investigated rhamnolipid-enhanced washing of drill cuttings and petroleum-contaminated soil obtained from northeastern British Columbia in Canada. The efficiency of PHC reduction was analysed and quantified via a Gas Chromatography equipped with a Flame Ionization Detector.

  • Cumulatively, all our individual footprints make up the unsustainable total demand. The solution to this problem is for people to take individual action to break down that large footprint. We need to change the way we live to combat climate change, conserve the world’s forests and protect our oceans. No-one wakes up in the morning and consciously decides to contribute to global warming; to help cut down a tropical rainforest; or to deprive future generations of a decent standard of living.

  • Moving to the new panel, check measurements again before cutting pillars etc. for jointing. At this point it is probably safer to leave a "safety margin" of about 1cm (in the right direction!!) when cutting any mid-panel joints. When the panel is offered up for a trial fit and clamped correctly in place, this overlap can be marked and removed more precisely, or crimped with a flanging tool so that one panel slots under the other. Clean up all surfaces to be welded, drilling spotweld holes in the new panel if required. Refit to the vehicle and adjust so that...

  • Remove trim, bumpers etc as required. It can make the job easier in some cases if the bulk of the old panel is cut off first with a sharp chisel, leaving the welded areas much more accessible. Make a quick note of where and how it’s welded, so that the new panel can be welded in the same places. (Note: some wings may be welded on to raised mounts, making weld position important!) Now each spot weld needs to be located and cleanly removed. Purpose-made spotweld drills are available for this, which work on the basic principle of...

  • The simplest drilling fluid is a dirty mixture of water and clay, often referred to as mud. The drilling fluid in the drilling process can be seen as the equivalent to the blood in the human body, the mud pump is the heart, and the drilled out shale (cuttings) represent the slag products. At the surface, we find the mud cleaning system which corresponds to the kidney and the lungs. In the mud cleaning system the cuttings are removed by means of a sieve, the shale shaker.

  • Drilling operations are perhaps the most popular machining process being undertaken today, with their origins being traced back to cutting tool developments in North America in the 19th century. In 1864 toward the latter part of the American Civil War, Steven Morse (i.e. later to design the significant ‘Morse taper’ – for accurate location of the ‘sleeved drills’ into their mating machine tool spindles) founded the Morse Twist Drill and Machine Company in the ‘North’.
