Deepwater activity in Asia Pacific has been largely centered on exploration drilling with a few projects going through into full development of commercial finds. New areas are subject to exploration activity with a growing interest in the regions deepwater acreage. This session will provide an overview of the deepwater drilling activity in Asia Pacific highlighting what we have learned from the recent past and what we can apply towards future activities.
Well control in deepwater operations is an increasingly important topic. Since the Macondo incident more and more regulators are looking at deepwater well control issues. This session take a look at the well control requirements and the blowout contingency planning requirements as they are operated in a number of countries. We will not only address the well control planning aspects but will also have a discussion about the environmental aspects as well as the well control response requirements with regards to capping stacks. Drilling the well is only one of the well control aspects, with the increased number of subsea wells, the well intervention well control aspects are also addressed in this session.
Advanced, cutting-edge and state-of-the-art technologies focused on improving the safety, effectiveness and efficiency of drilling operations in Deepwater environments are currently being successfully rolled out and deployed globally. Most of them focus on Managed Pressure
Drilling (MPD) technologies, whether of the dual gradient, constant bottom hole pressure, advanced flow detection and control, or the continuous circulation variant. Whatever the MPD type, these new technologies are making a large impact on Deepwater Drilling campaigns and have the potential to be able to do more once they are optimized and perfected with widespread utilization. This session focuses on the experience gained with ongoing projects in various locations utilizing these new technologies as well as the preparations being made to deploy new ones. It will also cover other new technologies that are on the cusp of being translated from concept stage to workable prototypes and even field trials, in the interest of sharing knowledge as to what more has technology have in store for drilling operations.
As Deepwater developments mature and prepare for long-term (and often permanent) interventions campaigns, the need to perform routine maintenance and repair economically is highlighted. This requirement has led to increased interest in the use of Rigless and Riserless Operations to perform subsea interventions. In turn, this leads to the requirement for wire line technologies that can reliably perform operations that historically have been performed in a riser-based environment. This session will look at some of the new technologies coming to market in this respect, as well as the systems that will deploy them in future.
Deepwater developments bring an additional dimension of challenge to the design and running of completions. The usual drivers of efficient and maximised production have to be weighed against reliability and the potentially ruinous costs of workover and repair in the deepwater environment. As such design can come down to a choice between zero tolerance for failure and a more holistic, life of field approach. In this session we consider a number of recent success stories and how they were achieved as well as how technology is to be applied as an enabler in one of the regions newest deepwater developments. Among the challenges in Deepwater completions are prediction and controlling of sand production, cost effective reservoir simulation program and avoidance of intervention.
The greatest efficiency challenge and consequently the largest and most expensive contributor to NPT in Deepwater Drilling Operations relate to issues associated with the reliability of well control equipment. This session will highlight efforts and activities currently available to address this critical issue from different perspectives. We will discuss improving root cause analysis, system improvement, improved response times, alternative methodology towards well control, systems designed to managed risk and aid decision support.
In this session major operational challenges associated with Deepwater Drilling will be discussed. For example, in progressively deeper water depths the use a marine riser for conveying drilling fluids from the well to the rig imposes increasingly restrictive limits on the use of traditional well designs. These restrictions are due to the considerable added pressure imposed on the well by a significantly tall column of high density drilling fluid within the marine riser. Reliably removing this additional (and undesired) hydrostatic pressure from the drilling process is the key to unlocking the potential of ultra- deepwater prospects utilizing the traditional well designs of shallower water depths. It is for this reason that Managed Pressure Drilling (MPD) and Dual Gradient Drilling (DGD) are focal points for this session. The ability to apply these drilling techniques in an operationally robust manner is a goal that most Deepwater operators desire to achieve. The discussion of this and other important operational challenges are planned.
Innovative and unconventional approaches to Interventions and IRM in Deepwater are taking place throughout the world. As new challenges faced by operators clash with the rising cost of rigs and a shortage of dedicated vessels, new solutions to a host of issues need to be sought. In this session we aim to bring case studies from around the industry that show a number of ‘firsts’, ‘one-oﬀs’ and intelligent approaches to talking intervention challenges both old and new.
Deepwater E&P poses many challenges as it is such a complex environment where there are no shortcuts to success. Every project requires long-term investment and commitment due to the following factors i.e. high cost, high risk, harsh/remote locations, challenging logistics. All this and more are testing the limits of industry resources. Advancement in Formation Evaluation Technology such as high resolution electrical image logs, formation pressure testing and fluid sampling while drilling tool provide the necessary info to validate the economic value and reservoir potential, managing wellbore stability in real time, refine and optimize the wellbore construction design.
