... Abstract This paper aims to present a field-wide case study that explores the use of Echometer survey as an alternative method for acquiring static reservoir pressure data. In Field X, located in the East Malaysia Region, conventional static gradient surveys (SGS) were typically deployed...

..., where water samples were collected. Oil, water, and gas gradients were calculated. Lessons learnt and inputs from Geomechanics were used in aligning the probe face and reference to the critical drawdown pressure (CDP). A total of 4,821 feet (1,469 meters) was drilled. 58 pressures were acquired...

... fracturing has been applied in Sanga-Sanga since 1980 until 2005 as first campaign but faced with many failures amounting 85% of the job failed. After a thorough study in 2006, one of the finding of contribution of failed job is high fracturing pressure triggered by high frac gradient. The study suggests...
