ExxonMobil Cepu Limited (EMCL), as the operator of Banyu Urip field in Cepu Block, Indonesia, observed several oil wells with high Gas Oil Ratio (GOR) after several years of production. Oil production curtailment was expected due to limited surface gas handling capacity. Additional stand-off against reservoir gas cap shall be established by performing top perforation interval shut-off to reduce GOR and maximize oil production. Perforation shut-off became more challenging due to high concentrations of H2S and CO2, relatively high reservoir temperature, long perforation interval, and total losses experience. The remedial solution required a V0 “gas-tight” qualification, live well execution, induced minimum to no formation damage, and provided minimum reduction of tubular Inner Diameter (ID) post remedial work to avoid significant production impact and allow future wireline tools deployment. Considering the high profile of Banyu Urip field, which currently produces ~29% of Indonesia’s oil production, EMCL selected the fit-for-purpose remedial method with the highest probability of success. The hydroformed expandable casing patch (patch) with Corrosion Resistance Alloy (CRA) material and its top-down expansion method was evaluated and selected. The re-designing of inflatable element was performed to improve durability in high temperature and verified by laboratory testing. Patches were installed and overlapped to cover the top perforation interval. Seals on top and bottom of the patch extremities formed V0 “gas-tight” sealing mechanism against the casing. The patches were deployed utilizing a smart coiled tubing. All patches were successfully installed as per plan. The wells were brought online with significantly reduced GOR post patches installation. This was the first installation of the patch utilizing smart coiled tubing and ~90 feet Coiled Tubing (CT) tower in sour wells within any ExxonMobil affiliates. The detailed technical preparation, strong safety culture and leadership as well as relentless learnings application have delivered a successful project to reduce Banyu Urip wells GOR and enable EMCL to maximize oil production.

Image Simulations

For well over two decades computers have played an important role in electron microscopy; they now pervade the whole field - as indeed they do in so many other aspects of our lives. The initial use of computers was mainly for large (as it seemed then) off-line calculations for image simulations; for example, of dislocation images.Image simulation has continued to be one of the most notable uses of computers particularly since it is essential to the correct interpretation of high resolution images. In microanalysis, too, the computer has had a rather high profile. In this case because it has been a necessary part of the equipment delivered by manufacturers. By contrast the use of computers for electron diffraction analysis has been slow to prominence. This is not to say that there has been no activity, quite the contrary; however it has not had such a great impact on the field.

Self Immolation

Over the last few decades there has emerged a small, yet influential eco-Buddhism movement in South Korea which, since the turn of the millennium, has seen several S?n (J. Zen) Buddhist clerics engage in high-profile protests and activism campaigns opposing massive development projects which threatened widespread ecological destruction. This article will survey the issues and events surrounding three such protests; the 2003 samboilbae, or ‘threesteps- one-bow’, march led by Venerable Suky?ng against the Saemangeum Reclamation Project, Venerable Jiyul’s Anti-Mt. Ch?ns?ng tunnel hunger-strike campaign between 2002 and 2006, and lastly Venerable Munsu’s self-immolation protesting the Four Rivers Project in 2010. This article will additionally analyze the attempts by these clerics to deploy innovative and distinctively Buddhist forms of protest, the effects of these protests, and how these protests have altered public perceptions of the role of Buddhist clergy in Korean society. This study will additionally highlight issues relevant to the broader discourse regarding the intersection of Buddhism and social activism, such as the appropriation of traditional Buddhist practices as protest tactics and the potential for conflict between social engagement and the pursuit of Buddhist soteriological goals.

The aim of this study is to investigate how the African novelists have domesticated the English language to suit their environments, experience and purpose. Specifically, the literary pieces – The Last of the Strong Ones (Strong Ones), House of Symbols (symbols), Children of the Eagle (Children) and the Trafficked of Akachi Adimora-Ezeigbo were x-rayed. This exploration adopted the Hallidian Systemic Functional Linguistics, which highlights how language is used. The textual method of data analysis, the primary and secondary data collection methods were employed and the results showed that the African literary artists in general and the Igbo Nigerian novelists in particular have taken on a unique style of writing in the African vernacular style. For that reason, the speeches of the characters are laced with dignified local appositives, high profile Igbo songs and tales, studded local proverbs, lexical transfers, ritzy transliterations and so on; and these have given African rhythm to the English language. This notwithstanding, the aura, glamour and credibility of the English language as the medium of communication are retained.
