Developed by ADNOC Onshore ASR - UC Drilling Department at Abu Dhabi (U.A.E.) the novelty involves six (06) different technologies necessary to minimize axial buckling in the monobore completion while maximizing well accessibility and integrity during the Rigless...

... of the expansion tool was good. Abstract The monobore solid expandable tubular (MSET) system, which maintains the same drift as the previous casing and enables the operator to maintain an original drilling plan to total depth, is the next generation solid expandable tubular technology - the most advanced...

... Abstract The use of monobore expandable systems has been theorized in previous works (Dean 2003, Dupal 2002) with various proposed embodiments. Commercially available sizes are limited to 8-1/2 and 12-1/4 wherein the size designation refers to the drift diameter which the monobore system may...

... Abstract This paper presents the success story of an exploration well in Malaysia which exemplary applied a breakthrough integration of 3-1/2″ tubing in 8-1/2″ hole cemented monobore utilizing a new well testing concept of Tubing Stem Test (TST) to save cost and rig time. The Tubing Stem Test...

... bend housing. There is a broad area of more than a 22-mile radius where the operator has drilled monobore wells in New Mexico, that has a similar scenario for comparison. The zone with the most wells drilled with Conventional and Compound angle motors was selected. The selected zone consists...

... Abstract Monobore cementation is defined as where a single production tubing size runs from the pay zone all the way to surface and is cemented in place. This type of well design greatly reduce rig time and cost. The challenge however is to achieve a good cement in the annulus as a well barrier...

... Abstract Coiled tubing (CT) milling of downhole plugs in large monobore completions is considered one of the most challenging CT workover operations, especially when conducted in offshore environments where intervention workflows are driven by efficiency gains for operators and service...

... Every drilling and completion operation has a room for improvement while staying within project's and safety requirements constraints. This paper discusses successful optimization idea from risk assessment to implementation in number of gas unconventional wells: cementing monobore 4 ½" 15.1...

... 14310 V0 rated (bubble tight) Straddle Packer assembly, fully compliant to H2S service per NACE TM0177 / ISO 11960 Accurate location identification of communication between production tubing and annulus in the corrosion resistant monobore completion of a raw gas injector well with ultra-high...

... Abstract One of the biggest sources of dry gas in the world is located in the Middle East. Every project in this field faces challenges that require good-quality downhole data to be properly addressed. In the present case, the risks involved when milling inside a 7-in. monobore completion...

..., and upper completion systems to create a monobore conduit. This new monobore completion system is rated for 15,–KSI target surface treating pressures. Traditionally, cementing and isolation objectives have been achieved using liners and liner hangers capable of deploying those liners and also isolating...

... in the Tarim Oilfield, confidence in a generalized model will encourage engineers to assess other opportunities. The ability to predict expansion stresses and sealability are also seen as the first step for the operator in the development of a monobore system that provides full pass-through and a casing...

... lift (CTGL) implementation in cemented monobore completion which uses 3.5 inch tubing has been a breakthrough in VICO Indonesia. This gas lift technique has been successful on arresting decline and even ramping up the oil production in this brown field. CTGL application in VICO uses only orifice...

... Abstract This paper highlights a unique technique used to overcome the specific challenge of locking open a failed-closed surface controlled sub-surface safety valve (SCSSV) in a monobore completion without a landing nipple profile above the SCSSV. The technical details of both the problem...

... Abstract The demand for reduced AFEs for horizontal wells drilled in the Niobrara unconventional shale play increased the need for improved drilling efficiencies. Better efficiencies can be achieved by utilizing monobore well designs which maintain a single diameter hole size for the vertical...

... Complex located in Zulia state. In view of this, it became necessary to evaluate the feasibility of building wells using monobore completion technology especially in the B6 LL 370 reservoir located in Tia Juana Field, Lake Maracaibo. Designing a monobore completion involves the construction of a wellbore...

... economically develop their acreage. An OHMS completion system with a cemented-back monobore well design will be highlighted in this paper as a viable solution for operators drilling and completing horizontal wells in the Permian Basin. The following discussion includes steps taken by the operator...
