... field applications in similarly complex wells. The new model allowed drilling personnel to identify the parameters most likely to induce fractures. Equivalent circulating density (ECD) had the most impact, followed by minimum horizontal stress, Young’s modulus, fracture length, and Poisson’s ratio...

... Abstract Exploration wells in India are being drilled to target tight sandstone reservoirs of Mesozoic age with potential hydrocarbon accumulation in the Gulf of Kutch (GK) & Gulf of Saurashtra (GS). Typical permeability ranges from 0.1 md to 2.5 md with effective porosity in range of 8...

... Abstract Due to the special working environment, offshore drilling operation faces multiple challenges such as narrow pressure margin, difficulty in detecting down hole conditions and high operational risk. A new managed pressure drilling equipment is developed and named as pressure control...

... Abstract Lost circulation is one of the frequent challenges encountered in the well drilling and completion process, which can not only increase well construction time and operational cost but also pose great risk to the formation. However, choosing the most useful treatments may still...

... Deep water projects are presently complex, where more drilling challenges can be encountered and higher uncertainty increases the risk of problems during the well construction phase, especially due to the narrow pressure window environments. Managed Pressure Drilling (MPD) is one...

... Abstract This paper demonstrates how an operator mitigated a hazardous pore pressure drilling risk using a technology that was new to the operator. The Seismic While Drilling (SWD) increased safety and efficiency at lower cost over commonly used alternatives. In 2019 MOL Norge AS drilled...

... Abstract Pertamina EP is an Indonesian national oil company which subsidiaries of PT Pertamina (Persero). For nearly 60 years, the Pertamina EP drilling area has been located onshore. In September 2017, Pertamina EP successfully conducted a Poleng N-2 well as the first drilling operation...

Collaboration between cross-functional project teams – construction, drilling, testing, and production – is examined from the economic delivery of several challenging wells under various environmental challenges and constraints...

... Abstract Applied annular pressure, for both managed pressure and underbalanced drilling, was born on land decades ago. In fact, the first Rotating Control Device (RCD), the critical component, dates as far back as the 1930's. Simply closing the annulus around the drillstring, and "bottling up...

... South China Sea is one of the offshore HPHT region, with the maximum 2.38 pressure coefficient, 480 degF bottom temperature and 50% CO 2 . The drilling and completion are challenging problems. This paper reviews the past 20 years' researches and practices in South China Sea HPHT area. Based...

... is achieved in PNPR cluster, historically and in near future. Ever since first production by PX and NX in 2004, infill drilling campaigns have been needed to sustain production above the economic limit of 5,000 bopd. Later in 2009, approximately a year after PR kicked off its first oil; the14 km pipeline...

... Stress theorem should be applied to. The novelty of dividing the subsurface into four zones using this new approach reduces the risk of predicting the pore pressure before drilling and the uncertainty of its correct calibration during drilling. This new pore pressure calculation is done separately...
