Paper Number: SPE-196291-MS
... of the well to recover most of frac fluid in formation due to reservoirs have been very depleted with pore pressure below 2.5 Ppg. From this finding it is deemed that reservoirs with pore pressure less than 2.5 Ppg are not suitable as hydraulic fracturing candidates and therefore losing opportunity...

... high mud weights are required (19 to 20+ ppg) with a very narrow window existing between formations pore and fracture pressures. In some wells this window is only 300 – 600 psi, and the formations are easily broken down resulting in losses. Once losses occur, they are usually total and can result...

... in the field. The results showed that both intermediate and production sections of planned wells would have narrow mud weight windows. Depending on the well trajectory, the production sections could have only 0.8 ppg drilling margin due to a higher depletion of deeper reservoirs. The analyses also highlighted...

..., and drilling was stopped following an uncontrolled loss rate and a diesel-oil stock shortage. Two suspected factors are believed to be the cause of loss circulation in Gunung Kembang: 1) depleted formation pressure, which recorded 6.8 ppg and led to a narrow margin of overbalance mud weight and minimum...
