Remedial Sand Consolidation: Case Study From Mahakam Delta, Indonesia

Abstract

Tunu and Tambora gas fields are located in the Mahakam river delta in the province of East Kalimantan, Indonesia. The fields consist of wet gas bearing sand bodies over a height of 13000 ft. The main producing zones are developed by intensive drilling with wells simply completed to allow a bottom up perforation strategy. The main objective is gas production from the deeper Main Zone layers. The shallow reservoirs prone to sand production are not primarily targeted. When sand production after additional perforation is observed, gas production is normally limited to maximum sand free rates or the wells are shut in to avoid damage to surface equipment. Sand consolidation has been used as a sand control method since the 1940’s. However, it had never been attempted in operator’s fields in Indonesia. To author’s knowledge sand consolidation is not commonly used in South East Asia, in general. Unlike widely used conventional sand control methods this alternative method allows production from sand prone reservoirs while maintaining full wellbore access below treated zones. The treatments presented in this paper were to validate sand consolidation as a viable sand control option in operator’s fields in the Mahakam Delta, utilizing new internally catalyzed epoxy consolidation fluid. The treatments were performed with 1.75’’ coil tubing and a packer. To date three Tunu/Tambora wells have been treated. The treated reservoirs have been producing without sand production after treatment. This paper describes candidate selection, job execution and treatment results.

A Review of Enzyme-Induced Calcium Carbonate Precipitation Applicability in the Oil and Gas Industry

“…EICP can be utilized to solve sand production issues. For this process to be applicable, certain criteria have to be considered, and many researchers have supported that the following criteria should be considered before choosing chemical sand consolidation as a sand control method ( Carlson et al, 1992 ; Wasnik et al, 2005 ; Chaloupka et al, 2010 ; Renpu, 2011 ). The bottom-hole temperature range has to be considered; in general, a range between 100 and 225°F is applicable.…”

Chemical Sand Consolidation: From Polymers to Nanoparticles

“…The experimental investigation, conducted by the researchers, showed that the compressive strength was 1340 psi at temperature up to 204 ℃ [55]. Chaloupka et al [56] applied catalyzed epoxy fluid to consolidate a sand formation in the Mahakam river delta, Indonesia. They reported that the regained permeability is 63% at the temperature range of 93-177 ℃, [56].…”

The Effect of Resin Injection on the Productivity of Shallow Sandstone Layer in Mawar Field

“…A research is required for the treatment of such problems in Mawar Field. Based on the observation, two wells in the field were decided to get chemical treatment [4,5]. The data of the wells are given in Table 1.…”
