Abstract

Drilling mud is a critical fluid in the drilling process, serving to maintain wellbore stability, transport drill cuttings, cool and lubricate the drill bit, and control formation pressure. In this study, a formulation was developed using bentonite, barite, and xanthan gum in specific proportions: 22.5 grams of bentonite, 11 grams of barite, and 8-11 grams of xanthan gum. The objective was to optimize the mud properties for a particular formation. After preparation, the mud was subjected to a series of tests in accordance with API standards, including density, rheological properties, filtration loss, and mud cake formation. The results demonstrated that the mud met the API criteria, with a density range of 9-9.5 ppg, a plastic viscosity (PV) between 13-20 cp, a yield point (YP) between 20-25 lb/100ft², 10-second gel strength between 14-21 lb/100ft², 10-minute gel strength between 17-24 lb/100ft², filtration loss between 9-14.7 ml, and mud cake thickness ranging from 1.47-1.76 mm. These findings indicate that the formulated drilling mud is capable of effectively stabilizing the wellbore, lifting drill cuttings, and minimizing the risks of kicks and lost circulation, thereby enhancing the overall efficiency and safety of the drilling operation in the targeted formation.

Abstract

Evaluation of Water Shut Off and Opening a New Layer of the Bagong Well in the Lesma Field, In oil and gas exploitation activities at the Bg01 Well, the well has been in production for a long time, so there is a problem where the proportion of water content in production wells continues to  increase.  compared  to  the  proportion  of  oil  and  gas  content  produced,  the  improvement  is carried  out  using  the  water  shut  off  method  by  closing  the  existing  perforation  holes  and opening  new  perforations  in  the  same  layer.  Or  closing  the  existing  perforation  holes  that  are indicated to cause an increase in water and the production of other perforated parts. By closing the  layer,  it  is  hoped  that  the  water  cut  will  decrease  so  that  it  will  increase  oil  and  gas production.
