Many small oilfields in poorly sorted and highly non-uniform unconsolidated formations with high fines content cannot be developed economically using the preferred sand control method, gravel pack. ‘J’ Field in Malaysia is a small oilfield with marginal economics that was developed successfully using stand-alone screen (SAS), a cost-effective open hole (OH) sand control method. Deployment of SAS in ‘J’ Field does not meet the industry-accepted criteria for sand control methods but provided the operator adequate sand control while fulfilling its economic needs. Recent advances in OH sandface completion technologies such as multi-layer mesh screens, inflow control devices (ICDs), and zonal isolation using swellable packers provided improved performance and reliability of recent SAS installations. This project marks a few firsts in sand control screen technology: World's first installation of multi-layer mesh screenMulti-layer mesh screen is the current state-of-the-art in premium mesh screen technology. It uses several layers of woven metal mesh filters of gradually decreasing micron rating and diffusion-bonded together, which creates a filter that provides better plugging resistance and solids retention capacity.Malaysia's first installation of tube-type ICDICDs are passive flow control devices that are used in OH horizontal (Hz) wells to delay the onset of water breakthrough and minimize its effect by balancing inflow from toe to heel or between high-perm and low-perm zones. ICDs are integrated with sand control screens for use in unconsolidated formations. Swellable packers are used in ICD completions to provide compartmentalization. This paper highlights the recent success of utilization of these cost-effective OH sandface completion technologies in the development of ‘J’ Field.

This paper will describea tubing cut operation carried out on a deepwater rig without having to first perform the usual, time consuming rig operations to work tension down to the target cut depth. Avoiding this standard procedure was achieved through application of a unique "Mechanical Cutter based Cutting Pad platform" (MCCP). Utilization of this technology enabled the operator to avoid having to unseat the tubing hangar and expose non-shearble across BOP and loss functionality of Surface Controlled Sub-surface Safety Valve. The other add-on benefits from this system is reducing number of wireline in the deepwater environment. Prior to introduction of MCCP, all others technologies recommendedthat the pipebe placed in tension achieve a successful cut. MCCP technology allows the flexibility of effective and efficient tubing cut with string in both tension and compression which is highly desirable in deepwater intervention. The is achieved as the tool incorporated grinding of tubing surface which enables a smooth cut. The first deepwater tubing cut application was in offshore India in February 2014 in a 5 well deepwater side track operation. In the 5 wells, MCCP cut three 5.5", 20 lb/f 13 Cr 80 and one 7" 29 lb/f 13Cr80. The MCCP eliminated several hazards associated with cutting the tubing in tension in this Deepwater environment and ensured that the operation was carried out in a safe and efficient manner. This paper will detail the efficiency and value added of cutting tubulars in compression or neutral load.
