Abstract

Mud is one of the things that is very supportive in drilling operations, the design of the mud can affect the effectiveness of drilling work, the costs to be incurred, up to when the well is in production. Of course what is expected from a mud usage is low expenditure and drilling with optimal results. Drilling mud plays a very important role in a drilling operation. Drilling that can run quickly, safely and economically is greatly influenced by the conditions and sludge system used. The condition referred to here is how the properties or rheology of the mud. Whereas the mud system referred to here is a certain type of mud that must be used with regard to the state of the formation and borehole. Muddy KCl-POLYMER is a non-dispersed mud, where the hydration and dispersion process of the shale formation drilled must be maintained or maintained as much as possible. There are several ways to achieve this, the most common of which is to limit the amount of water that reacts with the shale, by covering the cutting produced by the shale with the polymer as soon as possible to prevent further reactions with water. In this study, we will analyze the use and physical properties of drilling mud using KCl-Polymer sludge which is carried out in the Trisakti University Laboratory of Petroleum Drilling and Production.

Abstract

Y Field is a field that located on Sumatera Island. That located at Jambi Province precisely. This X well which will be drilled is a development wells at Y field. All of the draw well in this Y Field is an onshore wells. This X well shall be drilled using water-based mud. This water-based mud is used because it is cheaper and more economical than using oil-based. But, this mud needs tobe added an additive because the water-based mud has a deficiency in controlling the formations of clay. Planning of mud system for X well is using method of the offset wells, that is using around of wells data to be used as a comparison. This first X well drilled for hole section 26” by size of casing 20” with depth up to 150 ft and mud which used is type of gel/water. And then it is continued with hole section 17 ½” by size of casing 13 3/8” with continuing the former mud of drilling in hole section 26”. The depth starts from 150 ft until 1000 ft. The next hole section is 12 ¼” by size of casing 9 3/8” which a depth that starts from 1000ft until 4100 ft and using new of mud with polymer mud. Last hole section 8 ½” without casing and using polymer mud to continuing the previous drilling from the depth of 4100 ft until 4900 ft. Problem that faces by this draw well is the presence of faults and high pressure at depths below 1000 ft, so it needs to be prepared LCM (Loss Control Material) and Jumbo Bag to overcome the occurrence of kick.
