Abstract A set of 5 wells were to be drilled with directional Coiled Tubing Drilling (CTD) on the North Slope of Alaska. The particular challenges of these wells were the fact that the desired laterals were targeted to be at least 6000ft long, at a shallow depth. Almost twice the length of laterals that are regularly drilled at deeper depths. The shallow depth meant that 2 of the 5 wells involved a casing exit through 3 casings which had never been attempted before. After drilling, the wells were completed with a slotted liner, run on coiled tubing. This required a very smooth and straight wellbore so that the liner could be run as far as the lateral had been drilled. Various methods were considered to increase lateral reach, including, running an extended reach tool, using friction reducer, increasing the coiled tubing size and using a drilling Bottom Hole Assembly (BHA) that could drill a very straight well path. All of these options were modelled with tubing forces software, and their relative effectiveness was evaluated. The drilling field results easily exceeded the minimum requirements for success. This project demonstrated record breaking lateral lengths, a record length of liner run on coiled tubing in a single run, and a triple casing exit. The data gained from this project can be used to fine-tune the modelling for future work of a similar nature.

Potential Risks

The clinically available leadless pacemakers for patients with a single-chamber pacing indication have shown to be safe and effective. However, the optimal end-of-life strategy of this novel technique is undefined. Suggested strategies comprise of (a) placing an additional leadless device adjacent to the leadless pacemaker, or (b) retrieving the non-functioning leadless pacemaker and subsequently implanting a new device. Although initial studies demonstrate promising results, early experience of acute and mid-term retrieval feasibility and safety remains mixed. We suggest that the approach of leadless pacemaker retrieval is more appealing to limit the amount of non-functioning intracardiac hardware. In addition, potential risks for device–device interference, and unknown long-term complications associated with multiple intracardiac devices are prevented. The potential inability to retrieve chronically implanted leadless pacemakers limits the application of this novel technology. Therefore, long-term prospective analysis is required to define the most optimal end-of-life strategy.

In aesthetic medicine, during a course of skin whitening treatment, injections must be frequently administered to achieve a strong curative effect. To develop a method to prevent long-term harm due to injections, this study applied a novel technology for the delivery of whitening agents that achieved long-term slow release of agents, thereby reducing the danger of frequent injections. We utilized biodegradable poly(ethylene glycol)-poly(lactide-co-ε-caprolactone) and Span 85 as surfactants and squalene as the core oil to encapsulate and adsorb tranexamic acid in emulsified particles, respectively. The conductivity test determined that the continuous phase of the obtained emulsified particles was aqueous; tranexamic acid did not play a critical role because of its low content. The controlled release experiment demonstrated that the release rate of tranexamic acid from the emulsified matrix was in the sequence of (1) adsorption, (2) encapsulation plus adsorption, and (3) encapsulation. Encapsulating tranexamic acid can efficiently halt the behavior of sudden release and potentially boost the efficacy of whitening.
