“…The design was then modeled using a simulated BHA that included collars and stabilizers gauged to match the final swellable-packers, ICD screens and blank pipes sequences to ensure that the hole condition and DLS compatibility allowed the completion strings to be run successfully to bottom (Samie et al 2012) (Fig. This required an immediate interpretation of the permeability in each lateral within hours of its being drilled so that the ICDs could be configured accordingly on the rigsite.…”

Drilling, completion, and production monitoring and control of multilateral wellbores in highly unconsolidated sandstone formations have been successfully achieved both technically and operationally in the recent past, helping to ensure that planned production rates and reserves are achieved.Gravel packing lateral branches on multilateral wells is no longer challenging. Sound isolation of the main branch can preserve the mainbore of debris when milling the window and drilling the lateral, helping ensure seamless gravelpack operations. Stable junction isolation exists to support sand placement and subsequent reverse-out gravel pack operations in the main and lateral branches.With respect to multilateral wells, one of the key factors in terms of determining whether or not a multilateral wellbore might be suitable for a given project is the size and type of sand control completion and technique that might be necessary. The use of conventional standalone screens combined with multilateral technology has a long and highly successful history. Where more sand control reliability is necessary, the use of gravel packs or frac packs in combination with multilateral wellbores, technology is now available and beginning to develop its own successful history.In its current form, when combining advanced sandface completions with multilateral completions, gravel pack operations are subsequently followed by the installation of the multilateral and upper completions. As a result of a newly developed system, the junction completion can now be interconnected with the sand control operations in a single seamless operation.

Drilling, completing, and the production monitoring and control of multilateral wellbores in highly unconsolidated sandstone formations have achieved technical and operational success in recent past by ensuring that economic viability is attained and that well life is prolonged. Gravel packing the lateral branch on a multilateral well is no longer a challenge. Sound isolation of the main branch is achieved to preserve the mainbore of debris when milling the window and drilling the lateral, which will ensure seamless gravel-pack operations. Stable junction isolation exists to support sand placement and the subsequent reverse-out of gravel-pack operations in both the main and lateral branch. Additionally, it is no longer considered a risk to run long, stiff, bottomhole completion assemblies across the window junction. One of the key factors in determining if a multilateral wellbore might be suitable for a given project is the type of sand-control completion and technique that might be required. The use of conventional standalone screens has a long and highly successful history. And now, where more sand-control reliability is required via use of gravel packs in combination with multilateral wellbores, technology is available and is also beginning to develop its own successful history. Multiple successful installations of dual-bore, horizontal gravel-pack completions combined with Level-5 multilateral completion systems has resulted in increased reservoir drainage to improve the oil-recovery factor as well as the economic gains. In its current, form when combining advanced sandface completions with multilateral completions, the gravel-pack operations are followed by the installation of multilateral and upper completions. As a result of a newly developed system, one can now interconnect the junction completion with the sand-control operations in a single, seamless operation.

Since 1999, more than 120 wells in Saudi Arabia have been completed using multilateral technology (MLT). This paper will discuss case histories, associated technology improvements, and best practices in which dual-lateral completions, with and without pressure-isolated junctions (Technical Advancement of Multilaterals (TAML) levels 4 and 5), were developed and used to help ensure that each installation met the operator's objectives. Advancements and improvements in multilateral technology has led to reduced risk and enhanced well production, while addressing the operator's well challenges of maximizing reservoir exposure and increasing the use of existing slots. This paper uses end-of-well and incident reports to identify areas for improvement, the subsequent implementation, and the results of system modifications. Focused planning of drilling operations, wellbore preparations, installation procedures, and development of contingency methods led to the success of the installations. The operator's commitment to using this technology has reduced non-productive time and provided incremental cost savings as process improvements were implemented over the 15-year period. Multilateral technology in Arabian Gulf offshore fields has enhanced productivity using innovative techniques to fulfill the completion and intervention requirements of dual-lateral wells, with and without pressure-isolated junctions. Collaborative multidisciplinary teams comprised of engineers from the operator and multilateral service provider were assigned to help ensure the successful implementation of the technology. The system modification goals of improving consistency and enhancing the surface indications of downhole progress during the junction construction were met, thereby increasing the reliability and overall confidence in this technology. The multilateral systems were run in both new and existing wells, and the operator's objectives were met in each case. The successful implementation of this technology has expanded the use of multilateral completions in the Middle East. This paper provides an overview of the evolution of advanced multilateral technology well-construction techniques and describes how overcoming challenges became a catalyst for innovation. This technology is now routinely applied to increase reservoir exposure and meet development and production goals.
