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.

Summary This paper provides an overview of design and life-cycle considerations for certain unconventional-reservoir wells. An overview of unconventional-reservoir definitions is provided. Well design and life-cycle considerations are addressed from three aspects: upfront reservoir development, initial well completion, and well-life and long-term considerations. Upfront-reservoir-development issues discussed include well spacing, well orientation, reservoir stress orientations, and tubular metallurgy. Initial-well-completion issues include maximum treatment pressures and rates, treatment diversion, treatment staging, flowback and cleanup, and dewatering needs. Well-life and long-term discussions include liquid loading, corrosion, refracturing and associated fracture reorientation, and the cost of abandonment. These design considerations are evaluated with case studies for five unconventional-reservoir types: shale gas (Barnett shale), tight gas (Jonah feld), tight oil (Bakken play), coalbed methane (CBM) (San Juan basin), and tight heavy oil (Lost Hills field). In evaluating the life cycle and design of unconventional-reservoir wells, "one size" does not fit all and valuable knowledge and a shortening of the learning curve can be achieved for new developments by studying similar, more-mature fields. Introduction The emergence of unconventional reservoirs as critical sources of oil and natural-gas production has forced engineers and geoscientists to view field development in new ways. One of these areas is the life cycle and design of the individual wells and the upfront considerations that must be taken into account for long-term development. Unconventional reservoirs bring unique problems to design topics that range from well-spacing considerations to wellbore orientation, most of which need to be considered before the well is drilled and should be addressed as part of an overall reservoir-management plan. When considering the choice of a well type for an unconventional reservoir, one type is not appropriate for all situations. For instance, the need for a single, small-diameter wellbore in a tight gas field is dramatically different from the need for a horizontal wellbore in a shale-gas or naturally fractured oil system. Additionally, not only do the constraints of the initial completion need to be considered, but so does the length of the life of the well, which can be considerable in unconventional reservoirs. This paper discusses the design and life-cycle considerations for certain unconventional reservoirs. It defines the types of unconventional reservoirs that are addressed and discusses the specific situations that should be considered for such reservoirs. Certain case studies that demonstrate the need for such considerations are presented.
