Saudi Aramco's "M" Field is located offshore and will be developed using over 300 wells with a combination of land and offshore drilling facilities. Well number M-A is a land-based, power water injector well, drilled to an offshore bottomhole location. The resulting well design dictated directionally drilling an extended-reach well with an 8–1/2-in. horizontal-hole section over 13,900 ft (4237 m) in length. It was apparent from the outset that directionally drilling the 8–1/2-in. section was going to be extremely challenging. Once drilled, running and cementing the 7-in. liner would present a host of additional difficulties. To ensure a successful outcome, Saudi Aramco assembled a dedicated team of Operator and Service personnel to review all aspects of this openhole section and resulting liner running operations. The latest in directional drilling technology was used to ensure the exacting directional control needed to deliver the wellbore. In addition, running the over 14,400-ft- (4389-m)-long liner required the use of new and innovative liner hanger technology to overcome any challenges encountered during liner deployment. This paper will outline the planning, methods, and equipment applied to deliver the resulting 8–1/2-in. hole section, and successfully deploy Saudi Arabia's longest-ever cemented 7-in. liner. Introduction Field Description "M" field is an offshore field located in shallow water depths of 3–16 ft (1 to 5 m). The field has been produced since its discovery, and the current plan is to increase production dramatically by drilling more than 300 onshore and offshore wells. However, the location of the field in shallow water makes developing the wells even more challenging. Saudi Aramco's offshore drilling fleet consists of jack-up rigs that cannot operate in shallow water. The preliminary planning showed that 37 platforms are needed to be installed to meet the production target, and major dragging works have to be done for channels to facilitate the movement of marine vessels and rigs.
