Anti-Collision Risk Management Standard for Well Placement

Abstract The Well X in Nong Yao field, is an infill-well designed for the Gulf of Thailand which presented several interesting challenges due to its complexity, tortuosity, and potential collision risks with other wells. This paper demonstrates the application of a Real-time Advanced Survey Correction (RASC) with Multi Station Analysis (MSA) to correct the Measurement While Drilling (MWD)'s azimuth. The Well X is a 3D Complex design with a high drilling difficulty index (DDI) at 6.9, high tortuosity of 316 degree, and which has an aggressive build on inclination and azimuthal U-turning well path. The well also creates difficult doglegs severity (DLS) up to 5.5deg/100ft, which is near the limit of the flexibility required to achieve the horizontal landing point. The conventional MWD survey, with proximity scanning with the nearby Well A, demonstrates high risk with a calculated Oriented Separation Factor (OSF) of 1.01. The RASC-MSA method is applied with a clearly defined workflow during execution in real-time and provide significant improvement in calculated OSF. RASC-MSA is applied for every 1,000 ft interval drilling below the 9.625in casing shoe. The workflow ensures that the directional driller follows the corrected survey along the well path and especially in the last 300 ft before reaching the electrical submersible pump (ESP) tangent section. The result from RASC-MSA, indicated a 29 ft lateral shift on the left side of the MWD standard surveys. Without this technique, Well X has a high potential to collide with Well A and Well B (Figure 1) as the actual OSF may less than 1 while drilling. The final 3D Least Distance proximity scanning with Well A shows a minimum OSF = 1.35, which is a 30% improvement compared to the conventional MWD survey. Another nearby well, Well B, indicates a minimum OSF=1.66 and passed the anti-collision OSF rule. In consideration of the drilling efficiency, availability, cost effectiveness and time saving, the RASC-MSA analysis to correct the MWD's azimuth are applied and the separation factor can be improved by 30%. In conclusion, the collision risk management technique applied successfully met the complex challenges of Well X, which was successfully drilled and safely delivered.

This study aimed to identify to what extent Australian organizations have any plans to manage business continuity threats, and the nature and content of these plans. Sixty-four respondents who were risk management professionals were surveyed to explore the Business Continuity Practices within their organizations. The ANOVA analysis showed 39 per cent of the organizations had developed an enterprise-wide plan of which just over half stated that the plan was tested. However, 36 per cent of respondents had no plan, an “informal plan,” were developing a plan, or did not know whether they had a plan. Standardized guidelines for a process to manage risks have been developed across many spheres and countries and are brought together in the international risk management standard ISO31000 (ISO, 2009), which presents a process applicable to all organizations and all risks. Human resource practices that promote consistent communication and an organizational culture that allows business continuity plan values, attitudes and beliefs to become embedded and to move across traditional organizational boundaries are therefore important for gaining the cooperation needed to implement plans in an organization's operational areas pertaining to business continuity.

AbstractVessel biofouling is a significant pathway for the introduction of nonindigenous marine species (NIMS). New Zealand is the first nation to regulate the vessel biofouling pathway, with controls scheduled to come into force in May 2018. The Craft Risk Management Standard (CRMS): Biofouling on Vessels Arriving to New Zealand specifies the hull fouling thresholds that vessels must meet; and here, we present the evidence-based decisions that underpin these thresholds.Under the CRMS, a vessel must arrive in New Zealand with a “clean hull,” the thresholds for which are governed by the intended duration of a vessel's stay in New Zealand. For example, long-stay (≥21 days) vessels must meet a more stringent standard of hull cleanliness due to the increased likelihood of release and establishment of NIMS. While setting a clean hull threshold at “slime layer only” can be tractable when vessels operate within the specifications of antifouling coatings, incidental amounts of macrofouling can establish even under the best management practices. Because of such instances, the thresholds within the CRMS were designed to allow for the presence of some macrofouling species, albeit with restrictions to minimize biosecurity risk. These thresholds are intended to limit species richness and to prevent successful reproduction and settlement of the allowed taxonomic groups while considering the practicality and feasibility of implementation.The difficulties of managing biofouling on different areas of the hull are acknowledged within these thresholds. For example, a greater tolerance of macrofouling has been allowed for niche areas due to the difficulties in preventing biofouling on these areas.

Standard Framework

This study is conducted to carry out the risk management process in the logistics department of the electricity company unit, which has the main duties in managing electricity transmission assets, controlling investment and logistics transmission, and maintaining transmission assets. The risk management process in this study was prepared as a step in shaping the risk profile of business processes in the logistics field to avoid the failure of business processes that resulted in unavailbility of logistics material, which could impact the electricity transmission. This study uses the AS/NZS ISO 31000:2009 Risk Management Standard framework. Calculation of risk priorities is using Analytical Hierarchy Process, based on a questionnaire to experts in the field of company logistics. From the calculation using AHP, Work Accident (HR2) has been identified as the most vulnerable risk among others risk factors.
